WARREN CONNECTICUT – I’ve become obsessed with a lens that I bought for a song on eBay, the lens that I wrote about in my December 19 and December 20 posts. Further research indicates that work started on the optical cell (the optical workings of the lens) at the Karl Zeiss works in Jena in December 1945. So it actually is a Zeiss Jena 5cm f1.5 Sonnar. The lens cell was subsequently fitted to a Leica screw mount body by an unknown third party, probably in Germany, the UK or US, for sale in the UK or US. The distance scale is denominated in feet and Zeiss itself didn’t make any lenses in Leica mounts as Leica was a competitor (Zeiss and Leica were the equivalent of Nikon and Canon today). I can see why it would have been worth the trouble to convert this lens to a Leica mount: it is actually the equivalent of an modern lens in most respects at f4 and beyond – its performance is simply breathtaking and it has a lovely signature. I’ll be continuing to shoot with it over the next few weeks. Here are two images from today taken with the Sonnar on my Leica Monochrom.
This is what the lens looks like.
On this day last year: more fun with my iPhone.
