micro 4/3 adapter for K-mount lenses

There seems to be a Voigtländer (149 €) and a Novoflex (199 €) offering from a reputable source. These seem a bit pricey: what else is there? Expericence using one with K-mount lenses? (Behind these questions is the lure of a Panasonic GH2 ).

Got one of these from "rainbowimaging" on eBay. Looks very similar to the "Fotodiox" offered on Amazon. For the price the adapter is very nice, a snug fit, works great. It has the aperture control ring which allows setting aperture even on modern lenses without an aperture ring. The "throw" of the adapter ring is pretty short and there are no markings (except "lock" and "open") but it is still useful (I suppose one can meter fully open and watch the meter while closing the aperture to get to reasonably a accurate setting; seemed to work with the DAL 55-300).

Ended up getting a G3 instead of the GH2 I was eyeing at the time of the original post; initial impressions are that the G3 is a slick *little* camera . In practice MF with adapted lenses is works well, especially through the EVF; with the magnified view nailing focus with my M50 1:1.4 wide open goes pretty effortlessly. In dim light the EVF seems to get more noisy and laggy but I can still get well focused shots in far worse light than with the OVF of the K-5.

Does the focus change? E.g. using 50mm plus adapter equals the same 50mm or more?

There is still a crop factor. A 50mm lens on m4/3 has the same field of view as a 100mm on 135 FF. There is no loss of infinity focus.

I just bought two of these adapters, probably they're Chinese according to what I read but they're actually supposed to be decent. Someone on the M43 board I'm on told me to try them. He says he's never had an issue with one and they're less expensive. $10-12 a pop.

I'll let you know when I get mine how they went. There's a couple of sticky threads you should read on adapters here if you haven't already been here. I read just about every thread on here last night and really liked this site. Very informative.

I don't know how anyone can afford not to use an adapter and old lenses with these cameras. The older bodies can be had for a price that won't kill your budget too much but buying new lenses for one of these little cameras is killer prohibitive, IMHO. I can't even find one for my Pen that's under $200. It's a good thing I can MF, smile...

You can probably find the 14/2.5 for under $150 since a lot of cheap kits were sold with it and people split the lens and camera up for sale separately. Great little lens.

My favorite lens is the Pentax-110 1:2.8 18 mm
I make adaptors on my lathe.
Here are some of the lenses / adaptors:

I have this one and it works very well. The throw is small because it's the throw of the aperture flange on the lens. I used it with the 50-200 and the 15:
