50mm lenses test

[Ron (Netherlands)]

Bobby makes a good point. Is a lens that costs 10 times as much, but only 2 times better worth it? But you quote $1400 for a 50mm Summicron? They are about half that now (I compare 1950s lenses to 1950s lenses, not to modern Summicrons made recently). And J3s are about $200, so the good FSU lenses are only about 1/3 the cost. Not 10X cheaper, anymore.

I like most FSU lenses, and I've had a few. I've never had the proverbial "bad one" that people talk about, but never show examples from.

+1 - over the years had many FSU-lenses I could use and test. Never a bad one. Had about 7 Ju3 made in quite different years - all were good, but in the end sold all and kept one: the later black J3 because of its nice coatings and overall better condition than the older ones. Still use it.
...Oh and still kept the 20mm Russar....., not because it is a 'good' lens, but because it is quite exotic/rare

Btw I would never 'test' lenses on high grain film, makes it much harder to judge the results inho

You can buy this lens in better quality materials NEW, from Lomography, incl. a LTM-M adapter for Eur. 600,- :bang:

For this test I need the iso 320 speed during the time of this year. The test with sync and flash was not enough reproducible and I don't have a high bright LED continuous light for the test.

The best type of film should be an Ortho 25 film (e.g. from Rollei) which have a higher resolution (above 200lp/mm). But then you need much more lumen to do the test.
Further this Retropan 320 Soft I have in bulk now, which is very easy to make any suitable lenght for the film.

But I can redo on Kodak 5222 Double-X but this film is also iso 250.
