Apologies if this sounds a bit naive or silly, but it's something I'd like to know and here's a good a place to ask as any. Is there an adapter which is 'thin', or makes you feel that you are connecting your adapted glass to your A7 natively? Or to put it another way, I have a Takumar 50mm F1.4. Lovely lens of course and lovely size - but the size isn't lovely when I add it onto my camera with my K&F adapter. The adapter's great but the lens looks huge, almost ungainly when attached to it, especially when imagining it on an original film camera. I do appreciate that this is truly a first world problem in these troubled times and that maybe the answer's 'no' - but I thought I'd ask.
