Jupiter 8 and industar 61LD

I did some extended tests with the J-8, I-61 and I-50. At full aperture the I-61 is the sharpest lens however take in mind that J-8 =F/2 I-61=F/2,8 and I-50=F/3,5. At F/4 I-61and J-8 is about the same. The biggest problem is that a lot of crappy assembled lenses are going around so what you have to do first is a professional CLA and aligning on a collimator. And of course it will cost more then the whole lens which is normally Eur. 20 for an I-61. The difference between I-61 or L/D type (Lanthanium) is really a minimum difference, I would say neglectible.
Overall the I-61 is also a newer design then the J-8 made on old Zeiss pre-war calculations. In all round I would say the J-8 is a very good performer. I have the lens in LTM and Kiev/Contax mount.

@fotohuis, thanks for the info about the 'differences' between the two versions of the I-61 lenses. Id been wondering about that for a day or two.

In the Dutch analogue photo forum I made a test between the I-61, I-50 and J-8 versus Leica Summicron F/2-50mm. Conclusion: If you have a good FSU lens, CLA and put in the right way together the difference with a Leica Summicron is not that big. Yes on full aperture he Leica lens is the best, followed by I-61, J-8, I-50 but making just in practice a photo on e.g. F5,6 enlargement on 18x24cm you really have to look very good at the corners to find the differences. So you can be very happy with a good FSU camera (I prefer the Zorki-6 or a Kiev-4) with some good serviced lenses. I do not collect them, I use them all incl. my Leica M7. Looking at price-quality these lenses and cameras are amazing.

Something I didn't realisde earlier, is that it seems both the N-61 and 61LD are 'lanthanum' optics. So I was wondering if this impression is correct and if so, what does the 'D' stand for in 61LD?

D stands for M39 thread.

Thanks for the info fotohuis.

D stands for m39 thread.

Is that it? Seems a bit odd to me, after all the N-61 is also m39 thread.

You have also the L/Z version Z stands for M42 thread.

Thanks Fotohuis.

I see. Wouldn't it have been simpler to call one "61L39" or "61LM3" and the other "61L42" or "61LM4"?

No, it would not.
The letters D and Z comes from russian names which are equivalents of SLR and "viewfinder camera". As you know SLR and "viewfinder camera" have different register distance. Register distance is more important than diameter of thread.
You can always use lenses M39 produced for Zenit 3M and attach them to M42 Zenit. You need only simple adapter M42/M39. But you cannot use Jupiter 8 on Zenit 3M in spite they have the same M39 thread.

The I-61LD has one advantage over the J8:

1) When turning the aperture ring of the I-61LD, the focus ring won't move. :-)

Why couldn't they sort that out on the Jupiter?

It's only on later Jup 8 that the whole front body rotates when you focus. No problem on the Jup 8 from 1950 to 1970. A different build probably for economical reasons.

Jacques, What about the chrome/silver version that has a body that seems to be the same shape as the black one? If I turn the aperture ring does the focusing ring also move, because it's the same shape/design as the black one, or does it not move because it's made the same as the earlier chrome ones but the body is a different shape?


Here's a couple of pics showing what I mean. In the first pic look at the lens on the right, and compare to either lens in the second pic:

I-61 L/Z focuses much closer than the M39 version. Here is a picture I took with a digicam and I-61 L/Z. I use it often with digicam because it is better than the Canon lens that came with it.

Old FSU lenses do seem to be quite popular in the digital world. I've seen a few comments on them being better than the supplied modern lenses.

Quite and inditement on the companies that make the modern stuff, really.
