When I first tested this lens, my first impression was that it's very soft, so soft in fact, that I think it might have been designed as a soft focus lens. But I decided to go to Allen Garden to give it a go yesterday. Unfortunately I was there about 35 minutes before it was closed and the light was fading fast, I had to shoot at high ISOs.

As it turned out, this old Italian lens, though soft, has its charms. It renders pictures with some very unique characters. Yes, it's soft wide open, but it's so pleasing to look at, unlike the soft focus lenses that use uncorrected lens aberrations to achieve softness, which in most cases make the colours go wonky; this lens produces some of the most beautiful colours I have seen in an old lens. I think it will make a wonderful portrait lens. Hopefully I will be able to take some portraits with it soon.
