There is a sale going on at a large store offering a discount of 17 % on a lot of products ("we pay your VAT!"). So I went there and bought the Sony E 55-210mm. I've played around with it a bit and I'm beginning to wonder if I did the right thing. It's dark already so I have to use it indoors, but still: wow, the AF sucks bigtime! Most of the time it won't even focus, and "flexible spot" focussing is only possible for less than 5 % of the pics. dixeyk is right, AF on a NEX is just a cruel joke. I'll see if I can get by with manual focus. OSS is nice for sure and the main reason I bought it. Don't know yet about sharpness. Centre seems OK, but the corners aren't always sharp, have to do more testing. Looks like this thing is a candidate for a speedy return to the store! Fortunately they have a liberal return policy even if bought in the store instead of online.
