The Sony Alpha SLT-A77 is built around a 24MP sensor and a 2.4M-dot electronic viewfinder. Thanks to its unconventional semi-transparent mirror design is can offer 12 frames per second shooting and its phase-detection AF system works during video recording, providing fast and positive AF during filming - a trick that no 'true' DSLR can match. Ergonomics are on par with the best in this category, with well-placed external controls, solid magnesium-alloy construction and a textured grip for a secure feel in the hand. Staying consistent with Sony's best offerings, the A77 includes a number of in-camera processing and shooting modes like Sweep Panorama, Auto HDR and DRO Dynamic Range Optimization.

The A77 is a well-designed camera which spans the mid-range and semi-professional categories. Its headline features - high pixel count and blazingly fast continuous shooting - will attract a lot of interest, but of greater utility in day to day use are its effective ergonomics, reliable systems and excellent full-time live view system and full-time AF.
Everyday stills and video work in a wide range of situations, and casual sports and action photography.
Not So Good For
High ISO available light photography, and 'serious' sports and action work.
Very nice camera I have sold Canon 550d after 2 years (previously I have used Canon350d) and decided to move to Sony Trired Sony A57 for a couple of days, then A65 for a week and have bougth A77 finally a month ago Extremely fast and accurate AF NO preflash for focus in low light!!! Problems: No problems at all Noise is not a problem at all even at moderate high ISO Quite usefull even at 3200
After almost 1 year of using my A77 for my photography business, I am finally almost satisfied. It's impossible to satisfy a professional wedding or event photographer with a budget under $3000 for a DSLR, but sony has came close with speed and quality when paired with the proper G-Lenses. The only improvements I would like to see is a better external flash, WIFI and blue tooth options for event on site printing. My F58 flash overheats entirely too soon, even with medium activity shooting. ...
Excellent for Enthusiast or Semi Pro
Let me start by saying this; if you're not willing to work with settings to get your desired results, look elsewhere. That being said after about 10 minutes of playing with various settings and menus I had it dialed in exactly how I wanted it. It's weather sealed which is a must for a lot of us, and built like a damn tank. It's pleasant to hold, the rubberized grip is good. Weight isn't much of an issue for me, I couldn't really tell you if it's heavy or not. I like the EVF as much as an ...
For me the α77 with the 16-50 2,8 is the almost perfect camera. I owned the α55 before. I liked it, but It was a bit to small for me. When compared, the speed of focusing, the size, speed and color of EVF, the snappiness’ and responsiveness of the a77 are far better. I like the twin-dials, the top LCD, the weather sealing and the ability to bracket -3/0/+3 for handheld HDR's. Being Sony's second generation SLT camera, it is in basically every aspect better than the α55. The 16-50 lens is ...
Nikon V1 as a wildlife camera?
Hi I've been using my NEX-5R with 70-400 recently for wildlife shots - most of which need a lot of cropping. Optical quality is reasonably good but the body is not designed for this type of work and so buffer depth and other handling apects are frustrating I had been thinking of getting a Sony SLT-A77 (though the high ISO noise worries me) but the Nikon 1 V1 is going for a crazy-cheap price locally and I have a rather nice Pentax F*300/4.5 lens which I wonder about using on it via an Ebay adaptor - this would certainly be a cheaper option than the A77, but would it be a realistic one? Specs for the V1 seem exciting (able to take photos and videos at the same time) but I see that it doesn't have focus peaking and people complain about the image magnification for MF. I would be buying just the body and kit 10-30 lens, and am not interested in buying any Nikon telephoto lenses to go with it 1. Will a cropped bird image on the V1 be similar, superior or inferior to a similarly cropped ...
Here is a set on Flickr showing some shots I have taken with the Nikon 70-300 VR lens on my V1 with the FT1 adapter: http://www.flickr.com/photos/thekrankis/sets/72157637421120234/ I you decide to go the Nikon 1 route I would advise using Nikon lenses, since the recent firmware update many third party lenses that used to work with the FT1 now do not. The 70-300 VR that I use is an affordable starting place and gives an equivalent 190-810 reach. The 300 f4 lens is popular and gives superb results. Also the 70-200 f4 and the 70-200 f2.8 lenses perform very well - the f4 is probably more suitable simply because it is smaller and lighter. Have fun whatever you decide! Continue Reading
Yes, here is one taken with the V1 and a Nikon 300f4 (with 1.4TC). I think the goal with the V1 is to NOT crop. IQ isn't going to be as good as that from larger, recent sensors. The 2.7x crop factor, coupled with ability to do (accurate) central-point autofocus makes the V1 and V2 uniquely capable for doing certain wildlife shots. Namely those with a) decent to bright light and b) non-moving subjects. This thumbnail shot is uncropped: Nikon V1, FT-1 adapter, Nikon 300F4 AF-S with Nikon 1.4 TC. Here is a link to the large size version of the above: http://www.cjcphoto.net/lenstests/v1/images/130306-175446-00-2448-1%20v1.jpg Here is the same bird, without the 1.4TC (bare 300mm lens) but cropped in to about the same composition as the above so you can compare with and without the TC: http://www.cjcphoto.net/lenstests/v1/images/130306-175651-00-2458-1%20v1-crop.jpg The problem with moving subjects is twofold. First, you have only a single (largish) central autofocus point/area. If ... Continue Reading
The V2 has a 60fps mode. I've been shooting him for 5 years now. I suspect he'll be out there again in a week or so, if not already. (This pair of owls returns to the same nest near my house every year). Hmm. I don't know that I would say that. I did, of course, have more pixels on the owl with the TC than without, so there is some advantage in that. But any difference you see may well be more due to post-processing than anything else. You can take photos at the same time, though they are lower resolution JPG's, as far as I know. I don't have any convenient way of posting videos, except in Facebook. Last spring I shot several videos of the owls (3 chicks and one adult in the nest until they got too big). I did it mostly for the grandchildren to see the chicks getting larger each week. I hardly ever do video, except underwater, but the experience brought home to me the possibility of using crop factor reach in a way that you can't match with a D800e, or D7100. If you have Facebook, ... Continue Reading
Moving from Sony to Pentax
Has anyone here moved from Sony (preferably a700) to K5/30/5II?. What have you found to be the pro/cons? I particularly like the availability of a range of water resistant lenses as I shoot a lot from a rubber boat (the Sony option of a77 body is also WR but there is only one Sony WR lens at present). I can see a number of downsides, but don't want to start a war, so will just see what your views are in the light of use. I would prefer it if Maxeyesore did not respond as I am tired of reading his stuff on the Sony forum, however if he must I can just ignore it. cheers tom
Hey, Tom! I think I can give you some tips. It's been almost one year I've made this exactly switch. I'll be brutally honest here, so I *hope* Pentaxians won't get offended :) First of all, the GOOD about the K5: Even though it is a smaller camera compared to the A700 (and any other camera in the advanced-amateur category), it handles perfectly well. I don't have big hands, but smaller cameras tend to annoy me a bit. With the K5 I have had NO issues. It's a joy to hold (and look as well! It's so cute!). The position of the buttons also make sense and you can operate the camera without moving your eyes from the VF, much like the A700. The customization ability is AMAZING. That camera has so many settings, so many nice features, like a built-in time-lapse mode, that will keep you busy for a lot of time. I won't say anything about image quality, specially RAW, because at this point you must have seen already a lot of samples out there. But, in case you're still wondering, the DR and ...

Seals do fail and how you look after your equipment will have more affect on their life than design/manufacture constraints. Not knowing how wet and what you cleaning regime But for stuff like this a wipe down will see the seals lasting well, My k5 is 2 years old and no issues yet. On the DRO point made, the K5 has both shadow and highlight compensation these together replicate DRO but give more options as they can be tuned separates. Shadow compensation being an exposure offset has no impact on performance and can be utilized in RAW And the battery grip point, The k5 can be set to use grip first so I tend to use grip and keep body battery as a backup with nearly 1000 shots on tap from a charged battery I rarely use the body battery at all so never change/charge it. Ergonomics is more difficult I found the k5 horrible without the grip coming from a larger camera but now actually enjoy 'running light' when social shooting. Continue Reading
a77 Frame Rate in manual.
I imagine this question has been addresses before but why is the superfast frame rate restricted to Cont. Priority AE? I thought the technology would be easily built into M as well. I purchased the camera (and had a waterhousing built for it) purely for the advertised 12 fps. I only use the camera in the water with a fisheye lens (Sigma 10mm f 2.8) to get these kind of images. The surfer moves across the frame very quickly so even at 12fps each frame is very different. I only shoot on manual focus (with the lens set just back from infinity) and I only shoot with manual exposure, which is where the problem lies. I've done everything I can to maximise the camera settings to allow for a fast frame rate but with the M setting can only get up to approx 7 fps. I nearly always shoot in full light and rarely slower than 1000th of a second. I usually only shoot for about a half second for each sequence so the buffer is not the issue. Why is the camera faster in Cont.Priority AE than in ...
Yes, it could have been made available in M mode too. The main technical restriction of the high frame rate is that the lens diaphragm has to stay locked at the initial taking aperture instead of opening and closing between frames as it does in the other normal modes. The diaphragm open/close mechanism would not be able to reliably keep up with a 12fps rate. The other technical restriction is that if you also want continuous autofocusing during the burst, the lens cannot be closed down too far because AF will not work below a certain aperture threshold. Simply because Sony chooses not to allow it to work that fast in M mode. There is no other answer. Continue Reading
Probably to foolproof the feature.. IE in manual mode you than have to assume the user read the manual and knows what are the safe apertures and what are the safe shutter speeds. If not it doesn't work right and said user takes the camera back, or writes a long posting here about how lame and useless the camera is, or calls support, or sends it in for repair etc. Auto lets Sony make sure the camera is set in the operating window for 12 FPS. Continue Reading
... Except that the autoexposure feature still will fail to deliver 12fps if lighting conditions don't allow it, or if the user has selected an ISO that is too low for the conditions. In those cases the shutter speed will become too slow (in order to maintain correct exposure) and as a result, the frame rate will drop precipitously. Bewildered people have posted on this exact topic in the past, not understanding why '12fps isn't really 12fps'. It can never be considered foolproof, depending on the user's level of foolishness.
