Hi, Don here from eastwestphoto.net,
I used a Steinheil Tele-Quinar 135mm F:2.8 m42 mount in 1965~66 as yearbook Photo editor for my high school. I took thousands of photos processed in Microdol, rodinal and diafine all in B&W. What I rememeber the most was the amazing sharpness of the negatives and the fine printing I did on a Leitz focomat enlarger with those negatives. I could crop 25x with no problems. Somewhere in 1982 I sold the lens for peanuts when I switched back to Nikon gear. m42 thread gear was dead in the water in those days and my old Pentax H1a was not working.
Today I recieved in the mail from a eBay seller that exact same lens back again, in mint condition. Better than the one I sold back in 1982. I tightened some tiny loose collar screws and the helicoil was as smooth as silk! The optics were prestine, stunning, the A & M switch working and the bladed aperature oil free and working well. Well, where's my adapter and away I go! I mounted it on my test camera Lumix G-1 m4/3 rd's. The lens shade installed, the photos were unbelieveable! Just like I remembered as a kid, sharp as hell, great contrast. Look I have tested close too 250 lenses from the quality days of 1936~1978 on my G-1 and this lens is the equal of the best of the best!
I couldnt be happier, my G-1 loved the lens in weight and size and the chip performed well such that at 16x the image was still sharp! I still contend that the smallest best lens I tested was the Kodak Cine Ektar 40mm F:1.6 S type on a Cmt. adapter to m4/3 rd's and the Leica summicron-C 40mm F:2 was a stunning small lens also. Overall I rate the 16mm movie cameras lenses, best in the photo world, especially angenieux 25mm F:0.95, but the word is out on those lenses and they command small fortunes these days on ebay. Kino & plasmats are wonderful also.
As a shooter @ 270mm F:2.8 this lens will join my stable of fine concert lenses, when I am stuck in the cheap seats! The G-1 is a solid performer with stage lighting and even a cheap 500mm mirror lens @ 1000mm F:8 performs miracles from the very back of a giant arena! I love the G-1, love the adapting craze, I helped create on ebay and love experimenting. Now my loved Steinheil is home too stay for the rest of my life anyway. Regards, Don
