... likes film again.
DR Summicron also ?

I know of one more + a lens head that last I heard was in Australia.
I also had the pleasure of meeting Dr Mandler several times in Midland. Charming man - and what he did not know of optics - is probably not worth knowing!!!
In the end I sold it off, it was better than I could really justify - and I already had the 75f1.4 and the 75f2 Apo - and the VC 75f2.5.
It's not in Australia anymore.
My father was an optical engineer and knew Dr Mandler and Ernst Leitz quite well, but I never met either of them.
In the end I did the same - I have the M 75/.4, the R 80/1.4 and some other lenses of equivalent focal length. The f2 Apo is better close up, and resolution at infinity would be well down on my list of properties I look for in a lens. But the main thing I noticed about the 75/2.4 is that it had a sufficiently different spectral transmission from most camera lenses that it had a very odd tonality in B&W and required filtration in colour.
Marty, do you remember the serial number of yours? From what I found out, #1 was just a product test number, #2 and 3 where lensheads for testing on copy devices (only 6-7 aperture blades) and # 5/6 were put in 75f1.4 mounts. Someone at Midland told me that #5 was put in a shortened 90f2.8 mount. It was a very good lens - but collectors clamored for it and offering things like brand new Nikon Millennium kit + $1000's for it.
Never shot color with it - but in black and white it was deadly sharp. I suspect that the 752 Apo is close to it in performance - particularly close-up performance. Never had both at the same time, so it is a bit of a guess.
Mandler had a bit of a dry wit. We were having coffee in the Midlands canteen and he was explaining something about the 75f1.4 and the 180f3.4 and looked at me " Ach, you dont understand this at all!!!" I admitted that it was way over my head and he said "This is the problem, nobody really understands what I am talking about!".
He also stated that the 180f3.4 should have been sold without aperture blades and locked at infinity " That's when it is better than anything else - once stopped down and focussed close - it is just a very good lens". It was also the first time I heard about the M-mount version of this lens. Huge goggles that keyed in the 135 frame and magnified it to 180 mm view!
I have sen a couple - not pretty, but nice concept (supposedly 6 were made as a test and teaser for the US Navy.
