Hi, ok, so i've messed with a few cameras over the years, bauer 709,715, beaulieu 4008s, canon 310 up to 1014xls, eumigs, elmo and the odd nizo. Never used a nikon r10, seen results projected and they were extremely sharp. Sharpest super 8 (cartridge) images i've obtained are thru the 10mm cinegon and leicina special, sharpest super 8 zoom is the 6-66 schneider, another sharp lens is the 9-36 vario sonner on the zeiss ms8. Schneider 6-70 fitted to my 7008 pro is not as good as the 6-66, ang 6-80 is a wonderful lens, 64t for some reason looks terrific with the 6-80. The best looking and sharpest, clearest almost 3d looking images i have obtained have been with a bolex ds-8 with 5.5, 12.5 and 36mm primes, exposed using k25.
so,
1st place bolex ds-8 and primes
2nd leicina special 10mm cinegon
3rd leicina special 6-66 and 4008zm2 with 6-66
4th zeiss 9-36
5th 7008s with 6-80
sorry to bore you!!!!!
