Canon 50/1.9 collapsible shots anyone?

Hi, I just purchased a collapsible 50/1.9 from David Murphy (thanks for your patience! ) and I expect it to arrive next week. Any sample shots from this lens? I only get about 2-3 hits on flickr, and I can't find any more anywhere. Anyone have shots taken with this lens? Comments? Thanks!

This one may show the character of the lens. Think it was at F2.8. See the edges of the signboard left to center.


Another at 4 or so. The person in the middle stands out but almost no vignetting.


At F8, the lens gets sharp and contrasty all around.

Not sure, but I think it was said to be similar to the Summitar. The photos above suggest a somewhat curved field.

I got the F1.9 but prefer the later rigid f1.8 Serenar/Canon lens.

and its predecessor,

It does render like a Summitar, but shares the 1-2-2-1 formula of the Classic Planar/Xenon. I'm thinking it is like an updated and coated Summar.

I'm not a fan of the Canon 50/1.9. Just too soft wide-open for my tastes. I much prefer the Canon 50/1.4.

Nice, looks like the lens is chockful of character! haha... I'm expecting it next week. I use VC 40 and 75, and sharp as they are, sometimes it gets dull and I look for character! Can't wait! Thanks for the replies guys! Keep posting!

Thanks for the request for sample shots from that lens. These are from a recent outing with my grandkids, using up some outdated Tri-X behind a Canon Serenar 50mm f/1.9 lens. I characterize the lens wide open as having decent detail, dreamy at the edge and good contrast in the center. If you want absolute crispness, the 50mm f/1.8 lens is far and away better, but this oldie really puts some period in the image.

Gathering memories of fall




Pure joy!

just got my 50/1.9, it's a beautiful lens, but the only problem i have now is that it backfocuses on my rd-1 about 6 inches! anyone know how to fix this? my nokton focuses perfectly on the rd-1 so that's not an issue, my adapter works well with my 75 heliar, so the adapter is fine... it must be the lens... help please? anyone?

To check that the focusing helical is correctly assembled, see that the focusing cam protrudes exactly 7.50mm from the flat mounting face of the lens mount (the part that snugs against the flange on the camera.) when set at infinity. If that's not the case, the helical is probably assembled on the wrong start.

Also check that your LTM adapter is exactly 1mm thick. As in 1.00mm, to 3 significant digits.

If neither of these are the problem, this lens must have been built with an infinity shim ring inside like other Canon LTM lenses, and some nincompoop took the lens apart and lost the ring.

Well, the other possibility is someone took the glass out and put it together wrong...

I measured the focusing cam, and it looks about right (though i'm not sure since i don't have a precision ruler), and the adater is exactly 1mm. I know what the shim ring looks like in non-collapsible lenses, is it the same with collapsible ones? where is it located? thanks john!

Great shots everyone. I really like the character of this lens. I just got mine today and can't wait to try it out.

Is there anyway to tell when it was manufactured? I tried google but it turned up nothing more than eBay links.

You can ask someone who bought the Kitchingman's book... like me for example. Just give us your serial number.

I feel real frustrated not able to use mine properly! Any chance Kitchingman's book says how to calibrate focus on the lens?

This is what came to my mind after seeing the posted images. The Summitar renders more natural looking images.

So it's a Type 3, made between 1950 and 1952. Type 4 arrived in 1953 and types 1 & 2 were made in 1949.

It was the standard lens between april 1949 and december 1951 on the Canon IIB, III, IIC and IV bodies. Approx. 25689 units were made, most of them are Type 3.

It's a recalibrated version of the Serenar 5cm f/2 (which was a Gauss design). It was designed by Kuroki Masana, who also designed the very famous 50mm f/1.5 lens, released in 1952. It has 6 elements in 4 groups. It was replaced as standard lens by the rigid Canon 50mm f/1.8 in december 1951, on the Canon IIIA and IVF cameras.

All these informations are from the excellent Peter Kitchingman's book.

Reviving an older thread. Does anybody know if the lens can be adjusted so that it doesn't extend so easily? Mine doesn't seem to keep its collapsed position, and will extend if the camera is tilted forward. Which happens more often than you think, since the lens is rather front heavy, especially on a smaller screwmount body.

Anyway, here are a two examples, both shot using a Leica IIIf, Canon Serenar 50mm f/1.9, Kodak 400TX.

On most collapsible lenses the drag on the barrel is created by a ring of felt inside the base. You would need to remove the barrel from the base, lift out the old worn felt, and replace it. I do this on any collapsible I service, using self-adhesive felt from a craft store. Quite easy to do - all you need is a ruler and a razor, plus whatever you need to disassemble the lens.

Thank you for the tip, 02Pilot! Your blog post about this lens inspired me (in more ways than one, and for better or worse) to find a copy of this lens.

Try some dielectric grease on the lens barrel and in the guiding slot. Mine started sliding too freely after I cleaned the barrel with alcohol, but the heavier grease won't run and slows the sliding down, and is not supposed to migrate.
