This is fantastic! Didn't see this one coming.
Schneider-Kreuznach has been around for many many years. In Europe I feel their optics are more highly regarded than Zeiss. Besides, Zeiss seems little more than a licensed name, these days. When was the last time you saw a popular Zeiss lens come from Germany?
Interestingly (to me, at least) it was Schneider-Kreuznach who provided the first "planar" formula lenses to Rollei. They did this to spec with f/2.8 and f/3.5 versions, both remain wickedly sharp. Zeiss? It took them another year or two before they delivered optics to Rollei. In America Zeiss lensed Rolleis go for serious money. In Europe its the other way around.
Around the same time (early 1950's), Kodak was using it's optics manufacturing knowledge that it gained during WWII to build what remain today some of the finest commercially available optics ever. If you ever have a chance to resolution test (aerial inspect, not with film or a sensor) a Commercial Ektar or a Wide Field Ektar, perhaps you'll see what I mean. I'd love to have a tessar-formula 50mm for the DSLR that was this sharp/contrasty from WIDE OPEN in the center and rolled off nicely to the most beautiful out of focus rendition like those old Kodak Ektars.
Why do I bring this up? Well, because in Germany it was Schneider-Kreuznach that gave Kodak a run for their money. Not Zeiss. Schneider-Kreuznach could build great lenses that gave outstanding resolution and could pass contast (pre-MTF days) like nobodies business. I had a 360mm f/5.6 in a #5 air-shutter that had round aperture. It gave a gorgeous image, that lens did.
Yet today in America (and perhaps Asia too?) it is the Zeiss name that is more widely known than Schneider-Kreuznach. Well, except to large format film photographers where the brand and quality remain very well known.
I'll be interested to see what Schneider-Kreuznach does with these new lenses and, of course, what they'll cost.
Good Stuff, this.
