I think my bias against 67 lenses is probably because I imagine them overkill, or bulkier than necessary for the smaller camera. That might change if I had the opportunity to try one out. If I inderstand the crop factor correctly, the 120mm would be just a little too long for anything but tight headshots. I could use the 75mm for looser shots, but I'd like to have something in between that I could use without having to keep changing lenses. The 135mm LS on the full-frame 645 gives me headshots to 3/4 length shots in a small studio. On the cropped sensor 645D, about 107mm would be about perfect if I'm calculating the crop factor correctly.

I have the 67 105mm and the 645 A 120mm. They are almost exactly the same weight including the adapter for the 105mm. The 105mm is stouter, but shorter. The 105mm fits in my bag better and for non-macro stuff has a better focusing pitch. The 120mm is better optically and the camera exposure/WB works better with it and can naturally focus closer. I like the character of the 105mm, which is why I keep it around--I thought I would sell it after getting the 120mm. I don't shoot in a studio and so I have not really been bothered with or really noticed the 14% difference in focal length

The only remaining choice would be a 645 80-160mm zoom lens, which is bigger and an f/5.6. But that might not a big problem in a studio.

BTW, Travel 67 has some full-size studio portraits take with the 67 105mm on his Flickr site you can download. You should also look at his blog. I have a late version 105mm and I believe he does as well.

So Mahesh, did you end up buying the bright screen? And how did it work out?
