Review by Klaus Schroiff, published January 2012

The lens was kindly provided for testing purposes by Walter Greifenstein!


Pancake lenses are hot sellers in the mirrorless system world but unfortunately there're only a handful avaiable for full format DSLRs. As of the time of this review only Voigtländer offers two of such lenses in Canon EF mount and today we will have a look at the Voigtlander Ultron 40mm f/2 SL II. We already reviewed the lens quite a while ago on Nikon DX but we were curious how the lens performs on a full format camera. Like all SL II lenses it is a manual focus lens but it is fully coupled so a camera-controlled aperture, focus confirmation and EXIF information are all available. The Ultron is basically a standard lens with typical applications such as street and low light photography.

The build quality of the lens is absolutely beautiful. The outer barrel is made of metal and it's a pure joy to use the well-damped focus ring. Unlike on other pancake lenses manual focusing is also doable without major obstacles. The lens extends a bit when focusing towards closer distances and the front element does not rotate. The tiny but efficient dome-type lens hood can remain mounted without any significant increase in length.
