This is only rated as SR3, but that was my gut feeling (Items 4/5) that Sony's A580 was going to be the last DSLR with OVF from that stable. That was the reason I purchased one although honestly I did not need it just at the moment. So if you are into FF this might be good news. I think there is something in 1-3 because of the agreement between CZ and Sony announced some time ago. If the SLT and NEX do well, and the signs are there, then I think that the Sony APS-C DSLR with OVF will soon become history.(SR3) New rumors about full frame lenses and fullframe camera.
The following rumor is from an external source (Minolta-Forum.de). But I choose to post it on SonyAlphaRumors because the info posted by them is very close to the rumors we received from our sources. A German forum user talked with a Sony and a Zeiss representative at an event organized by Foto Sauter in Munich. Those are the five “news” he received from them:
1) Zeiss/Sony are already working on a few new full frame lenses. And the first lenses are going to be announced soon!
2) There will be new Sony-G full frame lenses. They will be produced in OSAKA (by Konica-Minolta)
3) There will be a new A900 successor with optical viewfinder.
4) The A580 could one of the last (if not THE last) APS-C camera with optical viewfinder
5) The future for APS-C is NEX and SLT
I think that Sony and CZ are going to have a go at the FF prof. market. Note also additional G lenses (if the rumours are right). These will be lenses that can resolve a sensor with probably 32-36Mp.
