Konica Minolta 28-100mm f/3.5-5.6 D AF Zoom Reference Material: Imaging Resources [no review] Used with: LA-EA3 Lens Adapter, Sony a5000 body I bought this lens to test the LA-EA3 Lens adapter on my a5000, and hopefully, to use thereafter if it showed good performance. On the LA-EA3 adapter there is no "auto-focus", but "auto-aperture" is supported, as well as some EXIF data. The lens has only two control rings, the Focus and the "Zoom". There is no aperture ring. The focus ring is at the very front of the lens and seems to be intentionally small so one does not accidentally affect the auto focus. Focusing turns the front lens element, including the filter mount (bad for polarizers). Using the LA-EA3 Lens Adapter The adapter is well made with an apparently strong tripod mount. It controls the aperture for exposure, but there is no support for depth of field preview. I think the only way I can preview the depth of field is to record a video clip. My first tests were taken at about 2' - 3'. I mounted the camera on a monopod but as I was moving around I decided to just take it hand-held, so the monopod was just dangling in the air.

"DSC00293a-rsz1640-C1.jpg" - no adjustments except for resize to 1640 - compression is JPEG minimum to preserve detail. "DSC00293b-Detail01-C1.jpg" - no adjustments except for the crop - compression is JPEG minimum to preserve detail The detail crop does not start in the far corner. I started it a bit lower at "0,900" because there are points along the bottom rim of the upside-down cup on the far left and the cup on the upper right, and the rim of the red lid below that cup which are in proper focus and are the best places to judge the sharpness. Note that at 1/80th sec. (hand held) it is possible that some sharpness might have been lost to motion blurring.
