when I bought it, it cost around 70 gray of course. and that's what I want to say . it's not worth the money! this is indisputably the highest quality glass of all that I have, but if you expect highly artistic masterpieces from it, then it will disappoint you. this is an excellent glass for reporting, weddings, funerals, etc. but no more. it does not distort at the edges, it does not chromate, we can say that it is sharp on open ones, but the postulate that fixes are better than zooms is absolutely true here! my old sigmapoltos for 18 gives a picture 10 times better. So the question is what is the money for? in other matters, as I wrote above for the reportage, this is probably the best glass in its class and no 24-105 was lying around.
