I'm looking into switching systems or maybe just have both Pentax and another one, and i'm super aware that what i need the most (excluding image quality, which one can take for granted nowadays) is a good autofocus, while a fast burst rate with a deep buffer will be largely appreciated.
I've looked into the original Sony A7 and heard people say its AF was mediocre at best, and that it has a really noticeable shutter lag. This last part would be dreadful as my needs pivot onto a pure sports use.
Is it as bad as people make it sound like?
The original A7 is still a decent camera, especially if you find one cheaply, but really showing its age these days. Continuous shooting is at 5fps - not bad, but not terribly rapid. Buffer clearing is leisurely, but not terrible. AF is OK using native lenses. EVF feels outdated compared to even the one-generation-newer A7 MkII. Doesn't support lossless raw shooting (ARW files use lossy compression which can compromise shadow recovery and result in occasional artefacts). No in-camera image stabilisation.
I nearly bought the A7 as a cheap full frame body for adapting vintage glass, but skipped it and bought an A7 MkII instead - which is also showing its age compared to recent offerings, but considerably better than its predecessor in a number of ways, not least the EVF. If you're keen on the A7, try to hold out for an A7 MkII at the very least.
