Sony A77 Review

« »

This is an in-depth review of the Sony SLT-A77 digital SLR camera that was announced together with the Sony SLT-A65 in August of 2011. I had a chance to test both cameras, along with a number of Sony / Zeiss lenses for the Sony mount, while reviewing the Nikon 1 camera system in late 2011. While I concentrate most of my gear reviews around Nikon cameras and Nikkor lenses, I got really excited about these Sony cameras after seeing the press release and decided to try them out.

Sony A77

I have been enjoying shooting with DSLRs for quite some time now and while I am very happy with the cameras and lenses I use, I just think that we have not been seeing major breakthroughs in new DSLR cameras. New cameras pack more resolution, faster frames per second, better video features and other bells and whistles, but nothing innovative and revolutionary that changes the way we shoot. With Sony entering the DSLR market rather late in 2006 (after acquiring Konica Minolta), it was tough to compete against the long-established Canon and Nikon cameras. Sony introduced a few DSLRs with great features at a competitive price and secured itself the #3 market share spot in DSLR sales globally, mostly with lower-end DSLR camera bodies. With a rather slow adoption rate and a limited choice of lenses and accessories available, the company quickly realized that its only way to challenge the big two was to innovate. In August of 2010, Sony announced its first “Single-Lens Translucent” (SLT) cameras – the Sony A33 and A55. While the concept of a translucent mirror is not new (in fact, Sony calls it “translucent” for marketing purposes, because it is actually supposed to be “pellicle mirror”), Sony was the first to design it to work with an electronic viewfinder. Its first SLT cameras were a success, so Sony decided to embrace the technology and take it a step further with the new Sony A77 and A65 cameras. Going forward, we will most likely not be seeing any more DSLR cameras from Sony, since its management already expressed commitment to this new breed of cameras. We should be seeing more cameras from Sony with translucent mirrors, including high-end, full-frame models.
