Sony Alpha A77

Summary

Our Score:

9

At ISO 100 images are clean and sharp and free of noise.

ISO 200 is virtually identical to ISO 100.

At ISO 400 and the A77 is still producing clean, noise-free images.

ISO 800 shows the merest hint of softening, but you really have to go looking for it.

By ISO 1600 there is some noise, and some softening, although it's still very usable.

At ISO 3200 noise is more pronounced.

ISO 6400 is the cut-off point in terms of overall image quality.

At ISO 12,800 noise is clearly visible even at reduced image sizes.

ISO 16,000 is really for emergency use only.

I own the A65 which uses the same image capture hardware as the A77 but skips a few of the "Pro features" for a substantial saving.

The images taken by this camera are excellent and the Video is 2nd to none, including the £5.5k cameras you list because of the SLT system and the continuous AF it allows. Also IS built into the camera has been improved even further and when capturing video you'll be glad you have it on every lens.

The OLED EVF has many advantages over normal optical versions (you seemed to just list the downside) including the ability to show you the effect of the settings you apply live as you shoot. There's also several "displays" that you can choose from that make taking shots that much easier.

SLT technology also allows true "live view" when using the rear screen when taking either still or video. Truly a godsend as more and more we use this over the viewfinder in everyday use.

I'm extremely impressed by this camera and highly recommend it.

The review was flat and had nothing new compared to other reviews.
It also have a very poor info on the outputs.

Finally, it is in no way as useful as your previous DSLR reviews (from 2008, 2009 and 2010).
I used to have TR as my primary source of un-biased info both for purchasing and selling.
Well, what a poor effort this latest one was.

DON'T BUY THE A77. THE LCD HAS NO COVER SO IT IS CAPABLE OF BEING DAMAGED BY SMEARS OF SWEAT/SUNCREAM/ SUNBLOCK. MOST OTHER SONY CAMERAS HAVE A COVER OVER THE LCD. SONY WOULD NOT REPAIR OUT OF WARRANTY FOR FREE
