Re: Wrong

I don't disagree, but what's a D-FA if not an FA (FF) optimized for digital ? While non WA DA lens will generally cover the FF field, the corners are likely to be rather poor and with significant vignetting, which makes them potentially poor FF lenses.

Actually, no, DA means "Optimized For Digital"; and most DA lenses longer than 30mm cover a 35mm frame. You seem very confused as to how a lens covers a frame ... and it has absolutely no relation to IBIS. You are speculating about lenses you've never seen or used.

Pure speculation; the 560mm hasn't even been finalized; and the 50/1.8 hasn't even been tested for frame coverage. Repeating rumors doesn't make them true.

"DA" officially only cover APSC sensor, and even though there might be some DA lenses that work on FF film cameras (but probably won't with a DSLR with IBIS), officially DA stands for APSC.
