I don't find the 67 105 to be magical, but it's a nice, fast long-normal for the 6x7 format, which makes a nice, fast short tele for 6x4.5. It's a double-gauss normal lens design that's fast enough to provide fairly narrow selective focus. But it's not magical.

The 67 SMC Pentax 55/4 is really an excellent landscape lens indeed, second in my bag only to the 45. The 55 is probably sharper than the 45, but the 45 is more useful for the say I see landscapes.

Nothing will be sharper than the DFA 55/2.8 for the 645d/z--it's a much newer design. But you won't find one for $159, either. In that focal range with P645 film bodies, however, I always used a 45-85 zoom. My normal lens for that format was the 75LS, and for telephoto portraits, I used an adapted Carl Zeiss Jena Sonnar 180/2.8, which is magic.

Hi Rick - are there adapted CZJ 180's around or do you have to get them adapted by a specialist? Thks Ian

67 55mm f4 vs 645 55mm f2.8

Some have been adapted permanently, but most of us use them with a separate adapter that mounts a Pentacon Six lens to a P645 body. I have a couple of those adapters, and I leave them on the two lenses I use routinely (the 180 and the Arsat Fisheye).

Is your 180 multicoated? Still thinking about getting one. Thanks.

The DFA645 55MM is on my 645Z most of the time. 2nd place goes to the 645 A 120 f4 macro. Both are stellar lenses for me.

Thanks,

Yes—look for “MC”. If it has a zebra focus ring, it will be single-coated. Multi-coated models will be all black. Earliest ones will have the angled rear barrel (like the zebra), but many of these are single-coated. Next is the stepped barrel with 8-digit serial number, last is the 4-5-digit serial number. The middle one might be best.

There is a black, angled-barrel Sonnar for sale right now already converted to P645. It is NOT multicoated.
