Lens Description: The 40mm f/2.0 Ultron SL II Aspherical Lens for Canon from Voigtlander is an ultra-sharp manual focus lens for use on Canon full frame DSLRs and SLRs. When mounted on a camera with an APS-C size sensor the focal length translates to 60mm. The lens\' manual focus action is very smooth and precise and its aspherical, multi-coated optics create sharp images with minimal aberration. Metering and exposure information is passed between lens and camera thanks to the lens\' CPU which provides auto-functions with virtually every compatible Canon 35mm and digital SLR.

Very good allround lens, esp. in combination with the assorted close-up lens.
There are still some downsides:
– night shots: halos around will develop point light sources at large apertures.
– bokeh on bright spots: at f/2, the highlights have an “atoll” shape (central point + ring)
– sharpness wide open is adequate, but no more
– geometric distortion is conspicuous.
So there’s a price to be paid for having a near-pancake size and weight, but the price of compactness is moderate. Overall, it is one of my favourites.
Although a manual focus, this lens is probably the most used in my bag. You’ll not find a lens sharper than this one. Bokeh is nice. Fantastic portrait lenth lens.
All I can say is that this lens is an excellent lens and then some (Along with the Voigt 28mm/F2.8 Skopar). Better than my Nikkors!
