Re: Will the A7711 be mirorless

If SAR is to be believed, the replacement for the A77 will have the sensor in the A6000. Since this sensor has a very fast on-board AF, it begs the question "Is there any further need of SLT technology?". Will this new camera be mirrorless?

Unlikely. Sony E-mount was built from ground up for mirrorless, while A-mount was developed for mirror based PDAF. The former takes into consideration any need for CDAF in the lens AF design.

But, A-mount lenses have been designed for PDAF only. Unless a6000 AF system is purely PDAF, it is unlikely to translate directly to A-mount as is.

A possible scenario is that new lenses and updates to some lenses (latest being 70-200G II) potentially have been given the capability to go mirrorless. This will involve design of SSM (perhaps SAM too) to add CDAF capabilties. But old lenses won't have the luxury.

If that is the case, a possibility of part time mirrorless exists. Whether this happens with a77 II remains to be seen but it could be mirrorless with these specific lenses (and any new/updated lenses) but to support legacy, SLT will be needed.
