Advice, please: Jupiter 8 or 5?

I don't believe I was, but I think I was responding to the comment about the 1 stop loss of speed that you did mention. It's my belief that there are enough other good things about the lens to make up for the speed loss. I am sorry if it came across as anything else. In the end, your vision will lead you, as it does all of us, and you'll use what is right for you. All I was trying to say was that the speed issue might not be _that_ bad.

Thank you for the information about your name. I always enjoy knowing that kind of thing from the time that I learned that my name, William, means "helmeted protector" in a very old version of German. Guess that's why I ended up in the Army 😀 <LOL>

I already have a Summitar, Herr Oberst Wilhelm Helm, but that f/2 beauty may be gorgeous in entirely the wrong way at full aperture at times. Thus my need for another 50/2 or faster. For work in good light, since I cannot afford an Elmar, the I-61 L/D is the only realistic option. Yours, Pudding.

Help! Someone please help! The photos I've seen of the J8 suggest that the chrome version does not rotate as a whole while the black one does (dual aperture scales). Is this correct? For obvious reasons, a rectangular hood is more efficient than a round one: but re-aligning it every time focus is changed is not my idea of paradise.

As Vince says, the J8 will flare in sunlight. Here is an example.

sure it has to be a politburo! 😉 you can call me max, btw 😉

politburo has a nice ring to it..in keeping with the
soviet theme, don't you think?

Doug, this nearest focus thing puzzles me. Everything I've seen gives 1 metre as the closest focus, presumably coupled. Might the lens be incompatible with your Bessa for some reason? Also, do other lenses exhibit the same behaviour on that body? Perhaps others who use other camera bodies will say if they too face this problem.

This is a standard issue with FSU glass on Leica spec cameras. I am not quite sure I know enough to explain it but has something to do with the camera spec, FSU cameras sharing the same spec with Contax while Leica spec cameras being built to a different focusing standard. Someone posted a link to Dante Stella's web site that explains this in more detail the other day. The lens needs to be reshimmed to rectify close focusing issues, but then the infinity focus suffers.

I got CV 50/1.5 Nocton instead, as I love 50 focal length.

So far as I am concerned, Wilt, any lens will show flare if there's any source of light around, not just the sun. The sky too is a source of light, which is often forgotten. Thus my hood paranoia and its logical extension, rectangular hood obsession.

I cannot figure out this specs business, Doug. For the same film format and the same focal length lens of the same optical design, you need a certain flange-film distance. Contaxes and Leicas should differ only in respect of mounts, focussing cams and followers. Do Jupiters behave in the same way on Leica copies (Zorkis, FEDs) as they do on Leicas? It is possible, of course, since they were Zeiss copies: but they have not been sold with Contax copies alone. Cam followers, perhaps?

Brian, the non-rotating front of which you speak is on the J3, while what concerns me is the J8. While I have messed with cocked revolvers, I haven't ever held one to my head with a round in a single chamber. Much rather aim an unloaded hand-gun at someone else's foot.

Brian, 0.1mm to 3mm is something like the difference in distance between Tokyo and Osaka on the one hand and the North and South Poles on the other. But not nearly so impressive as focus being off by 12 feet at 15 feet. How far beyond, say, Saturn does one focus if one wants infinity to be sharp? Gives an altogether new meaning to anti-standardisation and non-interchangeability.

Ever played Digicam Roulette? Specifically, a medium long head shot with background out of focus? I've been losing the game consistently for a year now, but my friend the Gimp is always around with a raft.
