Looks like I am going to be getting the 100-400L II a lot sooner than I expected.

The Tamron is crap at 600mm, but compare the two at 400mm.

C'mon now Rick.

A guy named Imagemaster who frequents other forums seems to get quite good results from the Tamron at 600mm. It isn't a Canon supertele, but it doesn't cost over $10,000 either. It offers a level of quality at a cost point.

I don't want to go on a cost crusade or anything here, but $1,000 for average Joe photographer is near the upper cost limit for a lens. At its $1,069 price the Tamron offers people who previously couldn't afford the entry cost for wild life shots. In the hands of someone as skilled as Imagemaster the lens can deliver really good shots at 600mm.

The Canon 100-400 II appears to be a great lens. And at its asking price it should be. It should take the Tamron behind the wood shed.

What I was referring to is that at 400mm the Tamron looks very good.

Not so much at 600mm. Corners appear very soft. http://www.the-digital-picture.com/R...mp=5&APIComp=2

The crap thought came in when you look at 400mm vs 600mm on the Tamron. To much fall off.

No doubt it is a fair valued lens and can take great pictures with the right skill level at 600mm. At 400mm it looks like it will have very decent IQ.
