I Would be interested to see how it compares against canon 100-400L as they fall into a similar price criteria.

The 400F5.6 is sharper than the 100-400...

If the 150-600 is sharper than the 400F5.6, then it is sharper than the 100-400..

Of course, when the series 2 versions of the 400F5,6 and 100-400 are released in 2035, things could change :)

Hmm...seems pretty good for the most part, although at 500 & 600 especially there was some hesitation going from the extremes, although I expect most super-telephoto lenses will have a pause if you are going to such extreme OOF areas if it's not sorta in the ballpark for focus distance.

It has a focus limit switch.... that should solve the problem in the real world....

Anyone else see this? A stark difference between the Tamron and the Canon 100-400L w/the Tamron much sharper. I'm a bit skeptical, not implying intention to deceive, but I notice shutter speed 1/8 on each...Maybe some mirror slap, or vibration to make Canon look so much worse? either way, Tamron looks good, esp if you go off center a bit.

Well, it's a fair test for the VC/IS systems. If it's handheld, I can't read the language, so I'm just guessing it was. Especially since they images are slightly different. We know that the IS system in the Canon 100-400L is of an older generation, while the Tamron will have whatever the latest VC that they have.

Although I do notice that the Canon seems to have a bit brighter, so I imagine it has a bit better of a T-stop, but that's just a guess.

Well right now it is priced at $1,069.00. And all we have is a few prototype reviews to depend on. I will wait 6 months for actual reviews from photographers and may be slight price drop. It is not going to stay at that price forever. At the end of the day it is tamron and price will drop a lot sooner than any counter parts from canon. But even at $ $1,069.00 its not a bad deal at all.

Another lens to compare this tamron with would be the Sigma 150-500mm F/5-6.3 APO DG OS HSM. Its also priced at $1069 at amazon however I don't see very good reviews there.

I had the Sigma 150-500mm, and up to about 400 mm it was not bad at all. However given the weight and overall performance I'm a lot more pleased with the 100-400 that I bought to replace the Sigma.

do we know how variable apertures match up to the zoom range? how soon does it hit 6.3? i would hope it stays at 5.6 up to 400mm at least.

150-250mm @ f5, 251-400mm @f5.6

Roger from LensRentals had 3 samples and all were well centered with little sample variation. He posted a IMATEST comparison today with the 100-400, 50-500, 200-500.
