I haven't had the chance to test the ZM 25/2.8 yet but from what i read on the interwebs, it is a stellar performer.
I vaguely seeing a press release of some sort from Zeiss claiming :
"When Hasselblad staff photographer Jens Karlsson took demo photos for the first Zeiss Ikon brochure in 2004, his photo of the carousel, taken with the ZM-Biogon 25 stood out for its enormous detail and clarity. So we used a ZM-Biogon 25 in a recent test to determine maximum resolving power. The high resolution film of choice was the SPUR Orthopan UR supplied and processed by SPUR. The result was a whopping 400 lp/mm on film, recorded with the Biogon 25 at f/4 in the center of the image. This value, 400 lp/mm, corresponds to the maximum resolution theoretically possible at f/4; in other words it represents the calculated “diffraction limited” performance at this aperture. It is noteworthy that this test was conducted with a production lens on a production camera, indicating that the film was precisely positioned and flat."
I cant seem to find this anymore but it surely left me wanting to play with the ZM 25/2.8
Anyway, here are some random samples from around my workplace from yesterday
Thursday is a public holiday here so some landscape/architecture shots are coming up soon
