|comment:||The seller listed this on eBay as being in good clean condition, but there was heavy fungus on an inner element lens element that ruined all images. The seller gave a substantial partial refund, so I took the rear elements out and did my best cleaning them. I improved the contrast greatly at 20 mm, but the previous II version was much sharper. Perhaps I messed up the reassembly. "JAPAN"|
The zoom mechanism is somewhat complicated and feels quite heavy but works smoothly and fairly consistently. The front element moves forward and backward slightly with zoom reaching a minimum between 28 and 24 mm. The rear element sticks out at 20 mm and moves forward about an inch at 35 mm. The front element rotates and moves forward with closer focus.
The build feels substantial until you look closely. There are holes and gaps all over for dust and debris to enter the lens.
Even in its current condition this lens is sharper than my better copy of the Minolta AF 20mm F2.8 (RS). It is good enough on an APS-C camera that it could be used instead of an APS-C kit lens. Then again the 18-55 kit lens has better image quality with much greater reach in a smaller, lighter body.
