Recently picked this up for a few bucks and tested it out tonight. It's an auto lens but on my NEX-7 I'm using it full manual and it's not the easiest thing to do. These are all hand held - the focusing felt jittery to me and I didn't think I hit on any of these until I took a look. I ended up with a hit rate of about 30%. I've only played with it for about an hour and I think I need to get used to how it operates. It has a separate "marco" dial that adjusts the magnification. It seems to me it would work best with a tripod.
