A-mount is a problem for Sony, they wish they didn't have the A-mount because it's a loose loose situation for them.
They are dammed if they let A-mount users down and they are dammed if they don't.
I think Yutaka Iwatsuki's quote about A-mount's future speaks for itself. They are only keep A-mount alive until E-mount can fulfil all photographic tasks (including sports and wildlife and very low light AF).
They fear A-mount uses reaction when they kill A-mount, so they pretend to care by releasing produces they know won't make a profit (no big sales), only to keep A-mount users from not leaving Sony altogether.
Many of us wished A-mount where the future but realises it's doomed, so we move to other brands or move to E-mount - unfortunately E-mount is not yet matured, too few native lenses, non for wildlife, too few fast zooms (although the most important ones are on it's way) and virtually no third part support...making all native lenses super expensive and from a price point uncompetitive compare to all other brands and formats.
Adapters are what saves the day for E-mount, allowing users to transit into E-mount smoothly, and with their old lens collection intact. Adapters will need to improve to the point where it can deliver almost native performance, or Sony's many features will suffer without native lenses.
I don't know what to say, but I hate A-mount is dyeing but can't do anything but watch and spend money, first at a dual system, then eventually a new system.
- A-mount future:
Yutuka says there are two reason to keep A-mount:
The first is that the A-mount has certain advantages over the E mount and, for now, we can not have all the same functionalities between A and E mount.
The second reason is that they “we have many customers that we can not give up. It is a promise to our customers.“" - http://www.sonyalpha...-our-customers/
