Ive always wanted to stay with sony. Although I've never seriously invested in glass for the A mount. I always like shooting sony and I knew I would stick to sony as I progress further into photography. So when my a700 started showing signs of a weakening sensor I bought the A99 and planned an assault on ebay for zeiss glass. 6 days later that A99 broke! An expedited replacement arrived at my door 3 days later... also broken, and with the same error!
The error? Steady Shot System Has Malfunctioned. The cameras were usable albeit with and annoying "error" on the screen and annoying popup warning at every button press. I dont know if there are other A99 batches with easily disrupted stabilization but these 2 are enough to convince me there might be a problem.
Ok so no A99 for me... What then? Not tied to any format with other glass I'm free to shoot anything. Enter the sony a7 and a7r. Smaller (lighter), better processing power, higher res, No stabilization but with stabilized lenses and a native dual mode AF (a7) with PDAF and Contrast AF. Im in.
I can see how A mount users would be upset but Sony wont drop A mount. They wouldnt have updated their white teles if they planned to drop the mount. They wouldnt have announced the 70-200gII (on paper) if they planned to drop the mount. The A99 missed the target too video oriented and not the total package, slow processing and interface, and a poorly made chinese grip that hardly matches the body. They will learn from this and fix it for the next round. There is a 4K camera as steffed mention coming in the future and a faster beast for a more real "pro" target (think d4, 1dx).
I ordered the a7 and sel35f28z, the sel55f18z and 70-200f4 will be next.
