Hi Kevin,
Many thanks for the review, it follows the same opinions I read in other places for this lens. I was thinking more into buying the 16-35... but maybe next year I buy this one instead (waiting for some months on the Sony... you can save some euros after their are some time in the shop in Europe).
If people are interested in the filter system, I read in other forums people already having in their hands the Nisi system, that looks nice... although 150mm size... Nice to know Wine Country is also designing a filter holder.
P.D.: Or you have wrong the info of the Nikon lens, it is a 14-24 f2.8 lens, not a 12-14. Or you are talking about other lens I'm now aware about... at least the link to B&H goes to the 14-24.
Regards,
David
