hello

I have a few questions regarding digitar lenses.
What is the relationship between digitar lenses and the
apo-componon HM lenses. Are they the same lenses ?

check out the PDF on the schneider website, the constructions looks the same.

I'm trying to find some info on this as I've been told that in the past
the 60mm and the 90mm componon were supplied to be used
with Sinar Digital backs.

The truth is I just bought a 90mm APO componon HM lens on a copal 0 shutter
because the guy said it is the same as the digitar. Now after transferring over the
money I kinda started to do the digging :|

thanks and cheers

I am not sure they really are but i am using apo componons as picture taking lenses ever since 1998 when i got my first 35mm digital camera. I adapted an old canon FD bellows to fit Nikon and used the FD to M42 adapter to put my various componons in front. I only did studio photography at the time but results made the well rated nikon micro nikkors look like the bottom of a milk bottle. No scharpening was needed to get perfect results. At nikon europe they simply said nikon lenses where better and that i should keep this to myself and not to upset others.....
Nowadays i still use theme vey often on my digiflexII or the contax 645 with CF39 backs.
Image quality is stunning but the out of focus rendering is not that nice.

Componon lenses = Flat Field design

Just try it and you will see how nice and extremely sharp they are. Cambo used also componons but were called digital cambonars, i have them in 90 an 60mm.

rueyloon, I had dealings w/ this gent as well. he seems pretty convinced they are the same, and seemed quite knowlegable on the subject. I use a 90mm Digitar daily on a cambo x2-pro w/ my 5D and the results are amazing. if it's anywhere near the the digitar, you'll be impressed. I was going to buy th 60mm off him, but not compatable w/ the x2-pro

I have the Cambonars - 60, 80, 90 & 120 that I were mounted in that big electronic shuter that Schneider developed for Cambo & the Megavision T2 system. Those shutters are worthless and all the glass was put into new shutters. I communicated a number of times with people at Schneider they all stated that all "Cambonar" lenses are "Digitar" lenses in superior quality.

All four of these lenses are wicked sharp - the best part is that I got all four on EBAY for $1100

This is obviously not a true statement. The "shutter" that you're suggesting is worthless is in fact, not a shutter at all, but perhaps that's why you did not find any value in it.

The MegaVision T2 and T32 have shutters built into the three pass filter wheel; internally in the camera back, which is why there's no shutter in the AutoStop mechanism. AutoStop apertures allowed 1/10 f-stop accuracy from stop down shot, to wide open, to stop down shot; all without touching the lens. This is because the AutoStop workflow was designed in concert with MegaVision's Photoshoot software-- you used the computer to control the opening of the lens for focus, setting the aperture for focussing, and setting the aperture for shooting. You can even see Color Coded Light Metering in live focus so you can set the lighting using modeling lights and expect it to match the strobe output (assuming you have good strobes like Broncolor).
