I located a Biotar 2/100mm (10cm actually) and wondered if I should buy it. Looks like the larger brother of the slim 1.5/7.5cm Biotar I bought a while ago. It won't come cheap though...

Like I said in the other message I think the focal difference came from destructive mount conversion.
This also means that the collecting value has dropped considerebly. Ok, maybe it could be more practical to use in m42 mount than in exa mount, but still I wouldn't buy for that sum a lens so much butchered. _________________ Alessandro

If it is Gokevins lens, it looks like it is a custom-made detachable converter, so there is no damage to the lens.
Or maybe there is a missing locking lug, I'm not sure. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

That would be a bit unfair I would guess, it is from around 1930.. But if it is as spectacular as the 1.5/7.5cm I would be tempted to get it...

I disagree with Attila this time, a 100/2 for medium format is something very hard to achieve also in modern times: Hassy Planar 100 is 3.5.
So I think that quality was the top for the period.
Problem is that from a collector point of view modifications mean a huge drop in price.
I'd let it pass for that reason. _________________ Alessandro

Biotar 58mm not same quality than 75mm at all. Within Biotar you can see also difference as well. |
Perhaps we need to think carefully about the understanding of "quality" - I regret I have no personal experience of these pre-war "light giants" but the designers' aims were to produce an optimal performance at an extremely wide aperture, in an era when film speeds were relatively low. In this case, "Biotar" refers to a family of lenses following a broadly similar optical design and it is indeed likely that members of that family would have produced images that differed from each other. But it would be inappropriate to label any of them as inferior quality.
I believe the fairest way to evaluate such lenses is to use them under the conditions in which they were designed to excel, namely poor light - either natural or artificial. We can, of course, have hours of pleasure shooting daffodils in the sunshine and comparing the sharpness and defocussed image effects (and I do !) but if we want to make really informative comparisons to show technological progress over time, I think we need to wait until the light fails ...
And again, a Triotar cannot properly be thought inferior in quality to a Sonnar or other more sophisticated design - Zeiss (and all other good lens makers) produced simpler lenses to meet more modest photographer requirements or more modest buying budgets. Can we really see any difference at f8 ?
I appreciate that not everyone will want to adopt my philosophy here, but I offer the notion for consideration. _________________ Stephen

I'm sure Attila was indeed making the point you highlight, and I wouldn't want for one moment to suggest he was being overly-simplistic ... my wish was really to get us thinking more broadly about how many ways "quality" in a lens can be understood.
This forum gives a wonderful chance for photographers of all ages to understand how much, or how little, lens performance has altered over the years. Those owners who submit their images are to be congratulated for their willingness to share their results and expand our knowledge, irrespective of whether they have the rare and exotic or the "commonplace and ordinary". _________________ Stephen

Yes, I would say this. _________________ -------------------------------
