I was sceptical about spending this much money for IS over the non-IS version. In fact, I was almost set to pull the trigger on a non-IS 2.8. But, after talking with a fellow FM member, I was swayed to this lens and bought it.
First impression was that it was very light and very sturdy and well built. Not a "pro build" lens? What does that have to do with anything? What constitutes a "pro build", and how will that do anything for me?
After mounting it on my body and running through a few test shots, my doubts about IS were put to rest. It is simply a god send! I have done some experimenting and have gotten some VERY crispy shots at 1/3rd of a second handheld in a very low light room!
Sharpness is very good at F/4 and gets lethal at F/5.6! Bokeh is better than I expected.
I don't have enough good things to say about this lens. It filled a void in my kit, and filled it well. I highly recommend it!
It slays me to read some of these "reviews". "No tripod mount, made of plastic and not 2.8" are the common "cons". Did any of you do any research at all before you bought it?
