Pros 1. Fast phase detection AF during video. No others have it.
2. 10 fps.
3. Nice in-camera editing features
5. easy to navigate menu
6. lightweight yet durable
7. Can shoot photo and video with just the use of the viewfinder.
Cons 1. the LCD could've been hinged to the side
2. Noise at high ISO compared to D5100. This can be reduced with NR and RAW
3. No intervalometer like D5100.
4. D5100 has better photo editing. but can do the same with post processing.
Summary I'll admit that this is not a complete review. However, I've high-lighted some areas that other reviewers might've not pointed out.
I've been looking for many years for the one camera I want to have with me all the time. One I can use for creativity, taking video, take with on travels, and provide great photos.
Started with Canon T2i. although nice, it lacked the swivel screen and did not focus well for video.
Moved to Canon 60d. Again, took great pictures but no autofocus during video.
Now, most poeple make a big deal that Canon's were used to shoot House and they all love the manual focus as well as set the exposure manually.
This is great if you can control the scene. In shooting a TV show or a music video, the scene is controlled. And you can do retakes, edits, etc. But you can't do that when your shooting a video of your kids running around at the beach or playing in the backyard. When you can't control the scene, it is tough to manual focus. Even with practice, let's say you get good at it... The sun glare may be too much to see the fine details on the LCD screen to see if something is in focus or not. ANd I think this is where the A65 (or any of the new Sony SLT's for that matter) separate themselves from Nikons and Canon's. Granted, the Nikons do a better job of autofocusing during video compared to the Canon's, they are not close to the Sony SLT cameras.
The downside with the Sony autofocus during video is that it does not give you control of the exposure except for the ISO. However, if manual exposure setting is important during video. You can do this by switching to movie mode and setting focus to manual. You lose the autofocus, but there are people that have managed to address this by pressing a button or two, which I can't recall now.
It is true that you lose some of the light coming in with the translucent mirror but I've read that this is about 1/2 an F stop. I did not see this to be a big of a deal unless you are shooting in low light most of the time.
I really like the fact that the D5100 had an intervalometer built in. I'm sure Sony can also provide the same with a firmware upgrade, it is all in the software.
Te D5100 also has an AF illumination lamp so that it does not have to trigger the annoying flash to focus in the dark. The a77 has a lamp, but the A65 does not and uses the flash like the Canon. I think this is unnecessary use of the flash.
I don't find much innovation coming from Canon. Nikon d5100 has great image quality and very nice features such as AF during video, intervalometer, and photo editing, connectivity to an exteranal GPS unit. So, if you want an all around DSLR w/o spending a lot of money, I would pick the D5100 over any Canon out there. If you want one that will keep you happy for the next 2 to 3 years and have a copule of hundred to add to the body, then I suggest the A65.
