This is a 40mm f/2.0 Aspherical lens for the Canon system. It comes with dome-shade and close-up filter. This is a great lens with electronic contacts that can "talk" to your Canon camera regarding exposure. Manual focus lens. This is the new, version of this lens. The focus ring on this version is fully metal.

I also own the Zeiss 50mm 1.4, but find myself taking the Voigtlander with me more often due to it's lightweight and compact design. Cheaper than the Zeiss, Voigtlander is manufactured in the same factory by Cosina and feels so much more solid then the (plastic) Canon 50mm 1.4. I can not recommend this lens enough.

This ultra-sharp lens brings its attributes to Nikon film and digital, particularly full-frame SLR's alike. I have mounted it on a vintage but pristine Nikon FG and it makes an incredibly sweet and petite package for walkabouts. It's superb clarity and color are of great benefit on the Nikon D700 full frame digital body. The operation is so smooth and silky it is very satisfying to use and makes one happy that it is a manual focus lens. It focuses in a snappy fashion when using the split image on a film camera or the focus indicator on a digital body. The lens shade is wonderful, not only because it is effective, but because it goes a long way to reduce the chance of fingers straying on to the glass. It is designed to function with a filter. I recommend a clear glass filter like the Tiffen (dirt cheap at Adorama) so the color quality of the lens is completely unaltered. Last but not least, the included close-up lens is really clever in the way it mounts into the lens shade and does a great job, too! Get one and enjoy!
Nail the focus and your images pop! Great buy if you don't mind focusing with the buttery soft manual focus ring.
Used for landscape and I found a 40 year old manual Nikon lens to be sharper. Can't recommend this product.
Excellent walking around lens. Fast at f2.0. The 40mm focal length is a bit different but hits a nice sweet spot between 35 and 50. Optically excellent. Works great with digital and film. The lens cap is a peculiar size if it gets lost. Excellent value for money.
I would use this as a walk around lens, landscape work. Didn't work to well: not as sharp as even 40 year old Nikon Lenses. Aperture control was a nice feature but this did not offset the fact that the lens simply was not sharp. Would not recommend it to anyone - buy a genuine lens for your camera.
The 40mm Ultron is a great companion. I keep on my D700 when I'm shooting for myself. It's small enough to use on the street . . . people and architecture look great. It's very sharp at medium apertures and is pleasant wide open. The close-up lens is surprising useful!
OK, after buying and loving the 90mm and 20mm CV lenses, I repurchased the 40mm - maybe I just got a bad copy ... or maybe I didn't give it enough time. The second time around, it's been fantastic. I put it on my D800 and it does the job - sharp clean pictures, edge to edge. Tough, lightweight. I just returned from five weeks of landscape shooting; the 40mm took 80% of the photos. It lives on my D800; great for landscapes, great for indoor/low light. I'm not a fan of "pancake" lenses, but I am a fan of this one.
Very small lens that delivers amazingly sharp results on the Nikon D800. I can count the hairs on each eyebrow AND can see every spot where the eyebrow has been plucked!
Wow. Excellent contrast. Far exceeds my expectations. Don't let the manual focus prevent you from purchasing this lens - especially in shooting still subjects. It is not the lens for every situation, but in the situations where subjects are still, you will not be disappointed. It is my new favorite lens. (I say that about all my lens). But I am continually impressed by this lens each time I use it.
good lens, but not autofocus
