Not my test. It easily covers the micro4/3 sensor. Will not cover APS. This is now retailed as the Ricoh lens. It sells new, for less than $100. You know not to buy a CS lens, right? The back focus is 5mm shorter, so only a macro lens. https://www.ebay.com/itm/1pcs-Used-Good-PENTAX-C2514-M-25mm-1-1-4-Lens-C1Xx/182254092648 Note: described as a C lens, it is also a B lens, Pentax speak for a 1 inch sensor. There are many lenses 25mm 1.4 that will not perfectly cover m4/3 sensor. For this length, they are about the best value lens, but a tad technical. As Robert Hart said, Fujian lenses are very good value and will easily sell on, should you not like their rendering. By no means are fabulous! C mount lenses all $300!! The "second wave" of Fujian lenses, all made in Fujian Province, often sold for more $$$ under other names, are far better behaved and some will cover APS, even tho' C Mount!
