Review by Klaus Schroiff, published September 2010

This time we'll have a look at a comparatively affordable "vintage" lens - the Voigtläander Color Heliar 75mm f/2.5. It can be used on a Sony NEX via a Leica M39 to Sony NEX adapter.

Such adapted lenses can only be used with manual focusing and "working aperture" - there's no data coupling whatsoever here. The field-of-view is equivalent to about 112mm in and in terms of depth-of-field it behaves like a f/3.5 lens in this scope - a rather obvious solution for portrait photography for instance. If you look around you should be able to find this lens for about 400-450EUR/US$ and it's often available for much less over at eBay.

It's a full-metal construction build to very high standards. The focus ring operates very smooth (dampened). The lens extends marginally when focusing towards shorter distances. Typical for adapted lenses a change of the aperture setting is applied immediately so you can check the effect on the depth-of-field on your screen (without the darkening like when stopping down a DSLR with a conventional optical viewfinder). The lens is supplied with a screw-in metal lens hood.

Manual focusing may sound like a major annoyance but it is not that bad actually. On Sony NEX cameras you can easily switch to a magnified focus view so accurate manual focusing is really simple unless you try to track a moving object of course. We recommend this camera-lens combination for static scenes only.
