You have a second copy coming? Indeed try it out. BTW, my 1855 IS update is here http://www.pbase.com/lightrules/evfzz
.
No disrespect taken. I guarantee you it ain't a "user error" issue for the poorer 55mm performance of E.
I would not exclude copy variation, especially at this level of lens. But images generally look fine overall when not peeping, even at 55mm. I'm not convinced it's a problem lens myself. But I can't be sure it's not either.
As to the IS noise, this one is dead silent. I've never used an IS lens like this before...and the effectiveness is superlative.
When the second copy of the 18-55IS arrives any time soon I will do some tests as well, no disrespect to these tests but all I can say is that those 100% crops are not as good as I found.
I think copy variation on this lens may play a key role, some also have said the IS makes a high pitch whine, I found the first copy I tested to be dead silent, which I found a little strange to get used to after the 24-105L, I like to hear its working.

Or maybe it really is a super 1855IS copy. That's possible.
