While E-mount news and rumors are pretty reliable and stable the A-mount future is quite more…unpredictable. The last couple of weeks I got in contact with as many as source as possible to try to gather some reliable info. And this is what I got:
1) A-mount is certain to continue.
2) Sony E-mount success caught Sony a bit “unprepared”. Therefore many A-mount product released have been “delayed” to focus resources and production on E-mount. This because that system needs to be broadened as soon as possible before the competition catches up. Editor’s note: This could be a reason why some of the rumored A-mount lenses planed for 2014 haven’t been released yet
3) Release cycle of A-mount products is getting longer.
4) New A-mount cameras will focus on a more high end market (likely no cheap entry level A-mount camera to come anymore?).
So hang on to your current A-mount cameras for a while yet, particularly if you don't fancy paying for the Pro stuff. I for one will not part with my A58 now.
