Better than Canon 35mm lenses!
By Ryuji Suzuki
First of all, this lens is manual focus only, so, unless you're super experienced with manual focus cameras, you don't want to shoot portraits, wedding or pets with this lens. But if lack of AF doesn't turn you off, this lens is actually amazing.EF35mm f/2.0 (the non-USM version) is an okay lens on full frame. It's not particularly sharp. it has rather poor chromatic aberration of magnification, so you get color in high contrast edges. The autofocus is slow, noisy and inaccurate. EF35mm f/1.4L is better in many regards, but it's not particularly sharp between 1.4 and 2.2. Chromatic aberration is also visible, though not as badly as the f/2 version.You know what, Ultron 40mm is very sharp, shows almost no chromatic aberration, and produces nice smooth images in or out of focus. It is not perfect in the sense that it has some vignetting, some corner softness, some flare/ghost with strong light source, but it's pretty good for five hundred bucks. With no strong light in the view, the image is not very highly contrasty due to slight to mild flare, but it's not too bad.These days, you can find 35mm f/1.4 manual-only lens from third party. They are reputed to be very high quality, but they suffer from the same shortcomings from EF35mm f/1.4L, namely, somewhat soft image. Ultron is sharper, yet produces soft out of focus blur. Another thing about Ultron is that it works with E-TTL metering. This is particularly useful for me, since I occasionally use a couple of 580EXII and 600EX flash units with pocket wizard. The other third party 35mm f/1.4 lenses do not have a microprocessor in the lens to allow E-TTL.One suggestion. You have to manual focus with this lens, so I strongly recommend getting Ee-S or Eg-S super precision mat focusing screen for your 5D/5DII/6D. I would not recommend using this lens on 7D or 5D3 because the viewfinder screen is not interchangeable and it's not as nice to work with manual focus. There are third party screens that you can install in 7D, although it requires using some jeweler's screwdrivers. If you are okay with that, it'd be a fantastic lens on 7D as well. You can't really enjoy using manual focus lens using stock viewfinder screen! (This is true for TS-E 24/45/90mm lenses as well.)The lens hood is kinda lousy. It does the job of protecting the front element, but not so good job of cutting stray light. Get a rubber hood with 52mm thread.I didn't test the close up attachment. To me, that's kinda silly. If I had to do close up work, I'd use a different lens. But, I got excellent image quality at the minimum focusing distance without using the attachment.

By Sean Dreilinger
I own this lens and happily recommend it to anyone who is comfortable with manual focus. Two thorough online reviews (one via ken rockwell and one via photozone.de ) offer in-depth testing and evaluation of the optical performance, build quality and ergonomics of this lens, but... The published reviews describe the Nikon version, and the Canon EF lens implementation differs slightly. Some information and considerations for Canon DSLR users:Manual Aperture Ring - the Canon EF version of this lens has NO manual aperture ring. All of the online reviews and even the documentation shipped with the lens show a manual aperture ring. I've uploaded a customer image of the cleaner, simpler lens layout for Canon EF mount.Camera compatibility - This lens plays nicely with every mode of my Canon EOS 7D - aperture is controlled via the usual dial assignments on the camera body (when working in aperture-priority or manual mode), and the camera can set the aperture automatically (in program and shutter-priority modes). manual flash and ettl-ii flash both work as-expected. The lens settings are recorded correctly in the resulting image metadata.Focus Confirmation - in conjunction with the manual focus ring, the autofocus points in my EOS 7D viewfinder provide focus confirmation when the shutter button is depressed half-way. imho this makes the lens much easier to use with the smaller, darker viewfinder of a crop-sensor DSLR.Lens Size - for those seeking a flat-as-a-pancake lens profile - the length of the Canon EF version extends 27mm from the lens mount on the camera body when focused to infinity, and 33mm when fully extended. the included lens hood adds another 2.5mm to the length of the lens. The reviews and product documentation offer "24.5mm" as the lens length, which must refer to another version of the product. I'm using the lens with a Sigma DG 52mm Multi-Coated UV Filter, which adds another 4.15mm to the lens length. the included lens hood is threaded to accommodate a 39mm filter (or the included close-up lens).photo-sharing site flickr has a "cv40" (Cosina Voigtländer Ultron 40mm f/2) group featuring ~6,500 images made with this lens. i found those sample images and information from current owners very helpful when researching this lens.

Just OK
By rai777
Looking for a good normal lens for an APS-C and having tried a few other candidates, I thought that I should try this manual focus lens. I figured that for this price and with the exclusion of auto-focus, I get a high quality lens. Mechanically, this was definitely true, but optically I was a bit disappointed as it showed more than expected focus degradation towards the edge (at least from f2 to f5.6) and fairly high coma. In overall IQ, it could not quite compete with my Canon EF 50mm F1.8 II or the Tokina 35mm f2.8 Macro (which replaced the Voigtlander). It was better regarding flare and faster than the Tokina, but offered less sharpness and resolution.
