After having switched from 50mm to 35mm for some time, I started to wonder if I should go even wider. I also wondered if I should maybe consider some cheaper options than Leica. The Voigtlander 28mm Ultron is about the same size and weight as it's Leica competitor, the 28mm Summicron ASPH. Given that the Voigtlander is almost as sharp as the Leica, and at a fraction of the cost, I told myself this was a no-brainer.
I ended up thinking it was too big and bulky. I used to carry my camera in my coat pocket, and with the Voigtlander it just didn’t fit. This was the main reason I let it go, but I was also happy to go back to a Leica lens. I missed the feel, look and build quality of Leica. Not that the Voigtlander is bad, especially this lens is amazing for the price, but it's no Leica.
The image quality is great! Especially on film, which is what I used it on, you probably can't tell the difference with the Leica in terms of sharpness. I never actually tested this, but you can base this on the fact that the Voigtlander is about as sharp as you can get on film. But even on digital I have heard this lens comes very close! However, sharpness is just one part of the equation. Although this lens also has a pretty nice and special characteristic, it does fall a little short in this area compared to Leica. But it's not really a fair comparison if you look at how much Leica costs. All in all, this is an amazing 'budget' 28mm option for M camera's.
