Originally posted by torashi Something similar, but FF, to the K-01 would be what you need, since the pentaprism and mirror is what makes an DSLR a lot heavier. I mean, the P67 is a world of a difference when using the flip up viewfinder vs. the regular or metering prisms.
But an FSLR needn't be that heavy, and it still has the pentaprism and mirror... It'd be interesting to know the weight budget for a DSLR vs an FSLR, to see where the savings could be made.
<ot> I think I would actually seriously consider a totally retro body for legacy lenses - all mechanical apart from the sensor and metering, something like an MX with a FF sensor in place of the film. No AF, just bring back the split screen and microprisms. No IBIS. No flash. No GPS (I'd miss that, but needs must...). If there's a self-timer, it's mechanical - otherwise you start "needing" to add solenoids... Battery fits where the film went, electronics in the take-up spool area and maybe across the back.
Possibly allow for a grip attachment so long as it adds (near) zero size and weight to the basic body; otherwise, just carry a spare battery with you, you do that anyway.

We now return you to your original discussion...
