Just bought this lens recently, after almost a year wait after placing order with Fotographfix. Probably wrong timing due to the Japan nuclear plants issues as this lens is made by Cosina in Japan. Guess it is too late a time to talk about this lens as much has been discussed on the internet since the launch of the lens : D.
What make me curious about this lens is its good comments almost everywhere over the ZM 28/2.8, its very impressive MTF and what Zeiss has demonstrated using very fine grain black and white film with a shot from hot air balloon.
I did a quick and non-scientific test between the ZM 25/2.8 and ZM 28/2.8 and think for my purposes they are equally good and the same amazing Zeiss quality. All my ZM lenses were early production batches. This late production ZM 25/2.8 now the focusing smoothness and damping is as good as the made in Germany ZM 15/2.8 and 85/2.
My test up was using a Voigtlander R4M with Kodak Portra 400 on tripod, mounted on a Metz 60MZ4 flash bounced at the ceiling. I have decided to compare based on same image coverage so the ZM 25 was moved slightly forward to cover the same composition. I used the f5.6 shots for comparison as the f2.8 ones I think there was inconsistency in focusing. The negative was scanned by the developing shop, but I could not see any significant difference in the first 16base scan so I asked for a scan in 63MB tiff. http://www.fuwen.net/index.php?option=com_content&task=view&id=107&Itemid=192
