Understood. But the initial lens offerings from Samsung don't offer
much in the way of wide angle lenses either.

I was surprised to see the lens selection starting only at 18mm (full
frame equivalent FOV 27mm) with an 18-55mm, 30mm fixed focal length
and a 50-200mm. The zoom focal length ranges seem uncannily close to
the kit lenses for the Samsung and Pentax DSLRs, and I suspect they
come from the same factories that supply several DSLR manufacturers
with these focal lengths.

For pocket use, I'd just get the fast normal, then any lens can be used
for tripod work. I have a 10.5mm fisheye, a 12mm zoom, a 20mm f/2.8
which is quite small. For lightweight hiking telephoto or sneaking into
a venue that doesn't allow 'pro' cameras, my 75-150 would be nice and
for closeups, my Voightlander 90mm f/3.5 APO Lanthar Leica screw mount
which is super compact and has a very limited 0.5x focus range on my DSLRs.

Canon now has a silent live view mode with electronic shutter, which
this actually lacks. That might be ideal for my macro bellows stacking
but I don't think the shutter actually causes much shake, it's just
painful listening to that mirror flap hundreds of times for no reason
for this application.

Most people would want their kit zoom and not mess around with lens
adapters. This should be an inexpensive entry level DX camera. If it
can't meter with weird lenses, I'm not interested.

It would be nice if some of your listed lenses would fit the Samsung,
especially the 10.5mm fisheye and 12-24mm zoom.

I'm not sure metering is so essential. After all, people manage with
non-CPU Nikkors on Nikon DSLRs and meter with a hand-held meter or by
trial and error. You just need a manual mode.

Alas Rollei are now bust, and Yashica ended TLR production quite a few
years ago. Although I know of a UK camera store that has a brand new,
unused Yashica 124G TLR for sale ...

A horrible, cheesy TLR. Better to get a Mamiya.
