MF lenses on Sony a900

Just to keep this group pumped up a little bit.

Slightly OT.

I've been using my MF lenses on a Sony a900 (36x24mm).

The results have been very good, but not better than my better
Sony/Minolta lenses of approx. the same FL.

The drawback is stop down metering (and AF, but I don't use that much in
any case).

Anyone else using their MF lenses on 35mm bodies?

Not yet. I'm not sure using one of my RB lenses on my K2 or LX body is
practial, at this point.

I recently bought an adapter to allow use of my Pentax 645 lenses on
my Nikon cameras, but haven't done much with it yet. The two lenses I
plan on trying are a 135mm f/4LS, for it's leaf shutter, and the 120mm
f/4 Macro in a head-to-head comparison with a 105mm VR.

How do you cock the leaf shutter and trigger it?

With my adapter, it is the camera shutter that is used, not the leaf in
the lenses (Hasselblad).

I compared the Hassy 120 f/4 Makro to the Sony 135 f/1.8 (non macro) for
very comparable results in the center area at max-close focus.

The Minolta (or Sony) 100 f/2.8 macro completely blows away the
Hasselblad (since the Hassy is 1:3 and the Minolta is 1:1 that goes to
follow).

My answer is "awkwardly at best." On the 645, the procedure
is described he

I think it's the roughly the same procedure when using the adapter.
Set the camera to manual mode at 1/8th of a second, select f-stop
and shutter speed on the lens, cock and shoot.

Mine works the same way, unless I want a 1/500th sync speed for
some reason.

Hasselblad (since the Hassy is 1:3 and the Minolta is 1:1 that goes to
follow).

The Pentax is 1:1 natively, so it ought to be interesting.

Hmm. No way I can do that with the HB lens as the leaf shutter
cock/release is on the back flange of the lens. No way to trip it (that
I can tell).

My Sony a900 syncs at 1/250 and the Minolta Maxxum 9 at 1/300 so it's
not that big a deal (For that matter, I can safely sync the 9 to about
1/350).
