Originally posted by hangu The corner sharpness of the DA15 lags behind by quite a bit in some of the photo tests I've seen. Even center sharpness seems to be better on the DA12-24. However, how can I argue with Photozone numbers?
I do think corner sharpness is pretty important in landscape photography, maybe not portraits.
I think Marc means when wide open. In landscape photography you usually step down and not using the lens wide open, and by then the difference would be pretty small. But still 12mm and 15mm can mean a lot for some people and especially in landscape photography.
I have both of them
I'm loving the 15mm now because it's so small, fit into my bag and allows me to carry 3 lenses in my small bag.
Also agree with Marc about cropping 15mm to get 21mm FOV. Actually I have considered 21mm too in the past but Marc (in one of his many replies) convinced me not to as I already have my DA 15mm. Thank you Marc!
