I think I saw someone else mention this earlier in the thread, but couldn't find it. At these magnifications you'll want to use a focusing rail. One driven by a rack and pinion or a threaded rod (like the Bogen 3419 Micro Positioning Plate) is best.

You can't focus effectively with bellows or by shifting the tripod at the magnifications you're talking about, so you need to move the whole rig (camera, lens, bellows) back and forth in very small increments to focus. It can be done with a sliding rail, but a rack & pinion or screw drive is much better.

Sorry to add to your equipment list. Have you considered reversing rings for stacking a couple of your existing lenses? See Shaw for how to do this and to calculate reproduction ratios.

Lee, I am aware of the difficulties of working at high magnifications and already use a focussing rack. I also use couplers and stacked lenses but I am looking at these movie lenses to go beyond what can be done with coupling.

A lot of old cine prime lenses have Series filter threads. Series 4.5 for the tiny lenses for 8 mm and Series 5.5 for lenses for 16 mm are typical. Here's (http://www.brentfinley.com/switar.htm) a guy who supplies an adapter from Series 5.5 to 49 mm.

As I mentioned before, I used the universal mix-and-match BPM bellows and this was long enough ago for BPM parts to be readily available and cheap. Here (http://cgi.ebay.com/New-BPM-BELLOWS-on-TRACK-RAIL-MOUNTING-RING-Leica_W0QQitemZ7602349541QQcategoryZ30059QQssPageN ameZWDVWQQrdZ1QQcmdZViewItem)is one on eBay.

Best,

I have 25mm f1.9 cine ektar (no II). Is there any difference with CE II?

FYI, I have a cine lens that came in a box of junk i bought. It just happened to fit perfectly on a reverse adapter i made to fit a 35mm ysaron on my cannon FD. I havent taken any pics, but from the viewfinder, it looks really good. I'm not an expert on macro photography but it looked bright and sharp. Let us know what you come up with.

I have read Lefokovitz, a good book.
Blaker states that the quality control of lenses is an issue of importance, so if you are thinking of doing something scientific with the lens, test a few and compare.

That's interesting.

I've read the Lefkowitz book several times, in fact I have it right now from the library, and I thought it has a pretty good discription on how to set up a movie lens for 35mm cameras. I wish it wasn't out of print, so that I could get a copy for myself.

The Lefkowitz book is available from many internet used booksellers. I bought two of them earlier this year for very little. One was given as a gift to a student and one I kept as a back-up.

I used a reversed Switar years ago before I got micro lenses. I have a 120/6.3 Macro Nikkor from the Multiphot system and the 12.5/2 and 25/2.5 Minolta bellows lenses from the Auto Bellows III system. Over the years I have used many enlarging lenses, both front forward and reversed, on bellows for macro work. The Minolta Auto Bellows III has some movements so the 60/4 Bogen Wide Angle enlarging lens works well with its extra coverage. The 40/3.5 Bogen Wide Angle enlarging lens, reversed, also works well. For coins and stamps I have had luck with an older version of the 80/5.6 EL Nikkor. Even enlarging lenses like the 40mm EL Nikkor cost very little today so I would prefer them to cine lenses unless I needed much more magnification.

I have Auto Rings for both Konica and Canon systems. If you don't need too much working distance then you can reverse a 28mm or 24mm lens and use an Auto Ring to get semi-automatic diaphragm control. With a flash or two hooked up this is a great rig for chasing moving insects.
