There are cases where you cannot get the correct information or cannot take advantage of some features without enabling JavaScript. You can also customize the Function Menu set (12 functions) accessible via the Fn button according to preferences. Assign frequently used functions and settings to these buttons and menus, so that you can conveniently access them to make quick changes, depending on the subject you’re shooting. The other settings can be adjusted manually. The camera records the images continuously at a maximum rate of about 12 images per second. The methods mainly used as examples in this booklet are AF-C and AF-S. Use Single-shot AF when the subject is stationary. When the shutter button is pressed halfway down, the camera locks focus when it determines that the subject is stationary, or continues to focus while the subject is in motion. Use this when the subject is in motion. AF-A can be replaced with this function. You can choose among nine zones. Even with 15 selectable AF points, in Expanded Flexible Spot, the eight AF points surrounding the selected one assist focusing, thereby maintaining focusing performance. Lock-on AF can also be chosen via Focus Area selection. Choosing a focus area for Lock-on AF lets you start tracking the subject from the area of your choice. Listed at the bottom of the choices is the mode that allows Lock-on AF to be activated when the shutter button is pressed halfway down. Even when shooting a three-quarter-view portrait, it can very accurately detect an eye closer to the camera and focuses on it. Once focus is achieved, the area in focus is indicated for a period of time, allowing you to confirm that the focus is where you intend for it to be. Pressing the button that Eye AF is assigned to while framing the shot activates Eye AF. When the camera determines that autofocus is enabled, the face detection frame turns white. When the shutter button is pressed halfway down, the frame turns green. Normal shooting mode.

Hi and Lo settings are available. When you shoot various subjects located at different distances from the camera, one after another, it is recommended to choose 5 (High). When you shoot subjects that become positioned behind other objects, it is recommended to choose 1 (Low). It is set to Fast by default. Setting it to Slow for Macro shooting makes focusing easy. Lock-on AF can also be started when the shutter button is pressed halfway down, and can be selected among the Focus Area selections. Pressing the button located in the center of the multi-selector starts tracking. Pressing the button again stops the tracking. Balanced Emphasis is handy if you want to achieve accurate focus, and not miss a decisive moment when shooting a moving subject. By limiting the autofocus range, you can prevent focusing on an unintended subject, thereby increasing the probability that the intended subject will be in focus. Pressing the C (Custom) button displays the AF Range Control setting screen. Use the front control dial and rear control dial to set the autofocus range. Press the C button to fix the setting. Various AF functions support your movie shooting: autofocusing by Face Detection function, wide Focus Area selections to allow focusing exactly where you want, AF Track Duration settings for movies, and control of when to start focusing action using the focus hold button. Choose an optimal Focus Area according to subject or framing intention. You can assign the function to a customizable button on the camera body instead of using the one on the lens. By using button customization, you can take advantage of advanced movie shooting capabilities, such as one that allows you to change a point of focus at the moment that you intend to do so. If you could answer the survey, it would be much appreciated. The survey responses will be processed statistically and will not be disclosed in a manner in which an individual can be distinguished.

Manual focusing is fun with my camera, here is how it works: Press the delete key on the back, an orange rectangle appears, move the rectangle to the area you want to magnify, press delete again. You're at 7.5x magnification now. Do the same again and you're at 15x. Most lenses today, no matter which make, are optimized for auto focus. I usually use manual focus when I take pictures of food which leaves me plenty of time to adjust as I need. If you shoot mainly non moving objects, you'll definitely be fine.It includes updates to Panasonic's DFD autofocus system, creative photo modes, and video features that come close to matching the more expensive S1H. 335 Nikon Z5 initial review review Sep 1, 2020 at 13:00 Nikon's new entry-level mirrorless full-framer feels anything but entry-level.

The best lenses for Sony mirrorless cameras Sep 4, 2020 at 22:15 Whether you've grown tired of what came with your DSLR, or want to start photographing different subjects, a new lens is probably in order. We've selected our favorite lenses for Sony mirrorlses cameras in several categories to make your decisions easier. The best camera bargains of 2020 Aug 13, 2020 at 21:58 If you're looking for a high-quality camera, you don't need to spend a ton of cash, nor do you need to buy the latest and greatest new product on the market. In our latest buying guide we've selected some cameras that might be a bit older but still offer a lot of bang for the buck. These midrange cameras should have capable autofocus systems, lots of direct controls and the latest sensors offering great image quality. That's a responsibility we take seriously, one that deserves the best effort we're capable of.The Sony A77 optionally comes bundled with a Sony DT 16-50mm F2.8 SSM standard zoom lens, which our sister site SLRGear.com felt to be a capable walk-around zoom. The lens features a built-in focus motor for fast, quiet autofocus, and is designed to be used with subframe Sony SLRs. For detailed test results, see our review of this lens on SLRgear.com. The A77's CMOS image sensor is smaller than a frame of 35mm film, so the angle of view at any given focal length will not be the same as on a 35mm camera. To find the approximate 35mm equivalent focal length, multiply the focal length of the lens by 1.5. (Thus, a 16-50mm lens will provide about the same view as a 24-75mm lens on a 35mm camera.) If there's a duplicate switch on the lens, then both must be set to allow autofocus; that is to say that if either control is set to manual focus, then the setting of the other control will be ignored. The dial on the body provides more control than that on the lens, however.

Instead of simply enabling or disabling autofocus, it's also used to set the AF mode to either Single-shot AF, Automatic AF, or Continuous AF. Single-shot sets focus with each half-press of the Shutter button, while Continuous mode is constantly adjusting the focus, whether the Shutter button is pressed or not. The Automatic setting will lock focus on a still subject or continually adjust focus on a moving subject, for as long as the Shutter button is halfway pressed. The default option is a 19-point Wide Focus area, with AF point locations indicated by small squares visible through the electronic viewfinder or on the rear-panel LCD display. Note that of the 19 AF points, only eleven utilize a cross-type sensor sensitive to detail in both the horizontal and vertical axis, with the other eight line-type sensors being sensitive to detail in one direction only. Wide AF bases its focus on the most prominent subject detail in the portion of the image that falls within the AF brackets, and the A77 can indicate which individual AF points achieved a focus lock by highlighting those points in green on either the electronic viewfinder or LCD while the shutter button is half-pressed. The camera will still automatically choose one or more points at which to achieve a focus lock, but it will restrict itself solely to point in your chosen group while doing so. In Spot mode, the A77 uses only the centermost AF point, and only this point is indicated by a square target box in the center of the viewfinder or live view display. Finally, Local mode is Sony's terminology for a manual AF area selection, also known as Flexible Spot in some earlier models. This lets you manually set the main AF point by using the Multi-controller to highlight one of the 19 available AF points. The active AF area is given a bolder line in the viewfinder and live view displays, and is again highlighted in green upon focus lock as a visual reminder of which point was manually selected.

Face Detection can detect up to eight faces simultaneously within the image frame, and adjusts focus, exposure, image processing, and flash output. Detected faces are indicated with gray frames, which turn white when they fall under an autofocus point. When focus lock is achieved, the camera indicates which faces it feels were correctly focused with a green frame. When no faces fell under a phase detection sensor, the A77 reverts back to showing the AF points that achieved a lock, instead. Optionally, you can program the camera to recognize the faces of up to eight specific individuals, who will then be prioritized over other faces whenever they're recognized in the image frame. Smile Shutter, meanwhile, can be used to trip the shutter automatically when a smile is detected.When held in, the A77 stops down its aperture to the selected value, allowing preview of the depth of field available in the scene. The function is rather more useful than in the typical SLR, however, in that while the view through the electronic viewfinder will dim while the aperture is stopped down beyond the camera's ability to correct for, the camera otherwise adjusts preview sensitivity to attempt to show the image with correct brightness. This makes it quite a bit easier to gauge depth of field with small apertures in good light (but perhaps makes the preview image grainier in low light conditions). This has two advantages over the more common flash-based AF assist on cheaper SLRs: it functions regardless of whether your flash strobe is raised, and doesn't dazzle your subject quite as much, so it's less likely to cause a blink. Together, these allow the A77 to counteract camera movement with movements of the image sensor, rather than the more common approach of moving an optical element inside the lens. Even the lower end of the specified range of effectiveness means a pretty significant improvement in one's ability to hand-hold long exposures.

There is also a manual cleaning mode, where the camera triggers a longer burst of sensor shift shaking. We've generally found dust-removal systems based on cameras' anti-shake systems less effective than those that use an vibrate the sensor ultrasonically, but it bears noting that no dust removal system completely eliminates the need for occasional manual sensor cleaning. Performance at 35mm was also quite good, with very good contrast and good sharpness across most of the frame. Results at the 50mm setting were similar, just a hint soft in the center and a bit softer in the corners. Still, with a total of 24 megapixels on tap, the cropped images are quite useful. (1.4x results in 12-megapixel images, while 2x produces 6-megapixel files.) Overall, a good performance from a premium kit lens. Flash was a bit bright but throttled down reasonably well, though lens casts a shadow. However with the 16-50mm kit lens set to 45mm, the Sony A77 captured a larger than average sized minimum area measuring 4.76 x 3.18 inches (121 x 81 millimeters). The flash did a pretty good job throttling down, though the lens casts a shadow, leading to a very uneven exposure. At the telephoto end, we measured just under 0.2% pincushion distortion, which is not very noticeable in images. This is the tendency for the lens to bend straight lines outward (like a barrel -- usually at wide-angle) or inward (like a pincushion -- usually at telephoto). The lens produced some soft corners at both zoom settings. Chromatic aberration in the corners with the Alpha A77's 16-50mm kit lens at wide-angle (16mm) and maximum aperture was moderate in terms of the number of pixels, so the effect was noticeable in a few shots. At full telephoto (50mm) and maximum aperture, chromatic aberration was less noticeable, with only faint coloration. The softness didn't extend very far into the frame, though, and the center was quite sharp.

At full telephoto, all four corners showed only slightly blurring, while the center was just a touch soft with lower contrast than wide-angle. You can also notice some minor vignetting (corner shading) from the darker corner crops, but it's really quite low. At full telephoto (50mm), chromatic aberration was again low in the corners, and very low in the center. Vignetting was low at wide-angle, and negligible at telephoto. The default setting for this correction is Auto. Sony. When it is difficult to get the proper focus in autofocus mode, you canNotesDo not rotate theRotating the focusing ring forcibly without.

Hence my concern e.g. one has focus lock, and therefore one starts to turn the Lens focus ring, but at that instant the target moves and the AF tries to re-focus; could this damage the AF mechanism. In AF-S once focus has been locked it stays locked, even if the subject moves again.To Switch between Automatic Focus and Manual Focus On Lens: Set Focus Mode Range Switch to AF Full or AF 3m-Infinity Range On A77: Set Autofocus Mode Dial (small dial near lens release button) to AF-A or AF-S NB. This switches between AF and MF. Furthermore the A77 Manual p.123 contradicts the Lens Manual. Why did I document this. OK one could call me pedantic or paranoid, and normally this sort of inconsistency does not really matter. As one could try an option, and if it didn?t work; or worked in a different manner than expected, one could work it out by trial and error. However in this matter one cannot safely try to turn the lens focus ring to experiment, because if the settings were wrong you could potentially damage the lens, camera or both Hopefully it will avoid me making a mistake, and would help other new users especially newbies like myself. I know it's a massive post - so apologies. If I'm not slaughtered too badly I will update the post when Sony Technical responds to the 3 outstanding issues.

If a moderator could move this post to the camera section I'd be very grateful Edited by Submariner - 23 February 2012 at 04:21 Thanks for the informative post.When using AF-A, if the camera senses the subject is moving the focus will keep up with the subject (in theory). If the subject is stationary the focus will lock. Once locked it will not change, even if the subject starts to move unless you release the shutter from the half press. Once locked it is quite safe to turn the focus ring on the camera without fear of doing any damage unless you release and press the shutter again. You mention you are worried about doing damage by experimenting. Don't be. If you try to turn the focus ring and feel any resistance then stop turning. If it is in MF (DMF) mode and focus has locked it will turn freely and no damage can be done. AFAIR the 70-300G can use DMF. It has a button on the lens to press which allows DMF. I'm pretty sure this is correct but will confirm later unless someone beats me to it. I'm wrong. Just flew into my head it's a focus hold button but can be used as DOF preview instead I think. Sorry to mislead you. Thanks for the long post full of info. Edited by russellsbags - 23 February 2012 at 08:35 I was 46 and suddenly life made sense.

When I push the shutter button, it focuses on something and allows me to fine tune it via the focus ring, and shows me via the peaking what area's probably are in focus. If something's moving using AF-A like this, I gotta use the focus ring to track them while holding the shutter down, or switch to continuous AF (C).

And I never use Single-shot AF, I don't know what's different between this and AF-A with DMF except for the AF-A with DMF showing me the peaking and allowing me to adjust manually. But once I put my Sony DT 50mm or the 35mm F1.8 on, which I believe have the built in focus motor, the AF-A with DMF stops showing me the focus peaking, but seems to do the same thing, focusing and then allowing me to adjust.When using AF-A, if the camera senses the subject is moving the focus will keep up with the subject (in theory). Hmmm not what the manual says, but I'll defer to your more expert knowledge. When you press and hold the shutter button halfway down, if the subject is motionless, the focus is locked and if the subject is in motion, the camera continues to focus.

But once I put my Sony DT 50mm or the 35mm F1.8 on, which I believe have the built in focus motor, the AF-A with DMF stops showing me the focus peaking, but seems to do the same thing, focusing and then allowing me to adjust. Well thanks for the post but I'm now well and truly confused. I thought you could only use Focus Peaking when it's set on MF. Yet your getting it to work with AF-A. What lens were you using to manage this? On AF-A there is no ability to manual focus. On DMF there is manual focus and also the ability to use focus peaking. If you have the AF-A setting on DMF (Page 123 manual) what happens is when the A77 has achieved focus lock on a subject it stops trying to focus and disengages the screw drive (focus motor) built into the camera. This only happens as long as you half press the shutter. With the motor disengaged you are free to turn the focus ring on the lens to manual focus. The camera will not try to focus again even if your subject starts moving as long as you keep the shutter button half pressed.

Also, while the button is half pressed the focus peaking will be activated as well as the focus magnifier if you have that selected. If you switch your A77 to DMF mode in the menu and then select AF-A mode on the front of the camera and then point at something and half press the shutter, you will see the camera focus and then you will hear the focus motor disengage. It makes a sort of quiet but firm click. This only happens on screw drive lenses and I believe you only have SSM lenses. Does this make any more sense.

If you want the subject to be in focus, you have to turn the focusing ring yourself until you think it?s sharp. C Continuous autofocusing.

Press the shutter release button halfway, and the camera will find a subject to focus on, and then it will assume your subject is moving and continue to adjust focus. Ideal for shooting sports or in other situations where the camera-to-subject distance is always changing. S Once the camera achieves focus, it stops. It won?t try to focus again until you release and then halfway-depress the shutter release button. This is ideal for most snapshot situations where the camera-to-subject distance won?t be changing. A Automatic mode lets the camera decide whether ?C? or ?S? mode is warranted. After the camera achieves focus, it continues to analyze the camera-subject distance and, if the camera thinks it?s changing, automatically shifts into ?C?ontinuous autofocusing mode. (I personally find its decisions questionable; but many others swear by the camera?s decisions.) So that?s what the 4 focusing modes do. What the AF-A setup menu variable does is allow you to redefine the ?A? setting from the description above to the following description: A Direct Manual Focusing (DMF) mode. This is identical to ?S? mode above, except once the camera has focused on a subject, the autofocus mechanism is disengaged and you are free to turn the lens.But wait! As mentioned in Chapter 2, this DMF feature when coupled with the Peaking function (page 231), even if you don?t choose to tweak the focusing manually the camera will highlight all of the areas in focus for you, acting as a sort of meta-focus-confirmation. Just turn the lens? focusing ring at any time. There is a benefit to enabling this feature with an SSM lens attached, though: it will enable the Peaking Level function as described above.I suppose I thought why should I pay L100 to overcome a badly written manual Plus ideally I like to work things out from the Mfg's manuals because it is then their responsibility if anything goes wrong. But seeing the extract of the book, I can definitely see why you Guys kept referring me to it.

Autofocus is too risky. The cat’s whiskers and eyebrows are a bit like the bars of a cage at the zoo and will tend to attract the autofocus sensors away from the eyes. I confirmed this by trying to manual focus with the new focus peaking enabled: the whiskers and eyebrows were highlighted red and it was hard for me to get the focus changed. In other circumstances, when I’m a little farther away from the subject, focus peaking is a wonderful feature that makes manual focusing easy and effective. I was able to move the focus area over the eye on the right, focus manually, and take the shot. Helped that Kiki wasn’t turning her head too much, of course. Next Post SONY A77 focusing options Notify me of new posts via email. The a77 is a very complex camera on it is quite easy to mess things up. Today my A77 stoped working, it can not see lens F value and I can not have. On. I missed photograph. I cant be the only one in the world that has that issue with battery life. Makes a grinding feel. I also have an A55 and it does not do that. No other lens feel that way on the A77. Any ideas?I'm from Mexico so I only had 2 choices for the kit, 18-135, or 18-200. After mounting the 18-200 I realized it had no mf-af switch, so I guessed it had to be managed with the knob on one side of the lens. I put the camera on manual focus and start playing with the lens focus ring, after some use I can tell you the grinding is still there but not as much as at the beginning, and so far (several months) there has been no issues with my lens in function, when I go to af it focus spot on. Either way, you may google that lens to see if that is normal.With a lens using the in camera motor, I have not noticed any grinding on my A-77.I will look on google. They are both under warranty but I don't want to send them in. That is my favorite lens. Thank you again!I rarely use manual focus, but I tried it out just now with my A77.

I do remember though experiencing the same focusing noise, no more, no less, when I used that lens on my first Sony DSLR - The A200. Is what produces the noise going to hurt the lens or the mount. I guess that's what you would want to know. For reference I manually focused my Sony f2.8 50mm macro lens on my A-580. Only a whisper of a sound there.I have had issues with older Sigma lens on newer Sony bodies, notably the Sigma 70-300mm kit and the 24-70mm F2.8 (which I had repaired and then sold).I wouldn't call it grinding. Grinding to me is harsher and more irregular, like sand in the mechanism. This feels like back driving reduction gearing because that's what it is. Quite normal for this lens.
