This lens is enormous and weighs a ton. Can't complain about what it does though. Takes mighty nice photos. Just be aware that it's big & heavy.

Very surprised this lens does not accept filters. That's a show stopper for me.

I am very please with the performance of this lens and with its relatively light weight. It allows me to carry two lenses on long trips which was problematic previously. However, I received a non US version. So, beware.
