Since so many of you asked, here’s a quick review of the quite affordable Voigtlaender Super Wide Heliar 15/4.5 on the Sony Nex. On the used market you get this lens for about 250 Euros. The newer P-Type lens, where you can even use filters on it, can be had for about 480 Euros new. I use a Kipon adapter to get M-mount lenses on the Nex, so the lens performance may vary among different adapters.
On the Sony the Voigtlaender becomes a 22,5mm lens. So you get a nice wideangle for landscapes or things.
I’ve been very impressed with this little lens on the Leica M8. It was brilliant, sharp and pretty much free of distortion. You got some dark corners, but that was easily fixed in post processing.
To give you an impression of the very nice performance on the M8, here are a couple of shots from a trip to Trieste in Italy last year (continue after the break!).
