I have just spent about two hours researching the web trying to locate specifications for the above enlarging lens and came up empty handed. I recently won one on e**y and it performs well for large prints and softer at smaller (< 8x10) magnifications.
Does anyone in cyberspace have a spec sheet or know what magnification this lens will produce its optimal performance?
I did read that it was designed specifically for color printing and was optimized for greater than 10-12X enlargements, possibly even 15X.
I would sure appreciate getting a handle on the published numbers.
