what do you mean by cracking lens?
this lens has been discussed in various thread. you can do a search and read about it.
"Cracking" in UKnese means very good......hot stuff..........very cool...........like that. British slang.
so if the seller has emailed me saying its an AF-special.......because it apparently says that on the box.... does that make it an AF-S or is he trying to pull a fast one?
I don't know about you guys, but for me I don't mind manual focus in macro mode. As a matter of fact, this is what I use most of the time when I shoot up close. Specially with flowers, you need to put the focus at the right place to get the nice effect.
So if you're buying the lens mostly for it's macro capabilities, go for it.
