I agree, the images are looking good despite being web sized. The bokeh looks fine and I really don't see anything that looks wrong with them. If this does release at $1500, I'll pick one up right away to try out.
Does anyone know how many stops the VC in Tamron lenses usually gives?
At the very least, the bokeh looks good and the lens looks reasonably sharp at 600mm, as best can be seen from those tiny samples, and contrast looks quite good.
Only thing that got me worried was the misconception that this was an internal focus lens, not having seen the 200-500 extended till I go to Photozone's review, at which point... wow.

Internal focus, yes. Internal zoom... hell no!

I don't belive you understand what an internal focus lens is.

That MTF chart looks very good to me for a zoom. The 10mm lines give us a measure of contrast, the 30mm lines a measure of sharpness. Sagittal lines mean radial and Meridional mean circumferential. The good thing is it looks pretty good at 600mm.
Here's the Sigma 50-500/150-500 MTF's for comparison. It looks like the Tamron is beating those two out. based on what my friend was showing me with his 50-500, which I was already surprised at how good it was, this might be a pretty darn good lens. Let's wait and see if the real world analysis backs this up. http://i33.photobucket.com/albums/d73/Telecorder/1Bigmav150-500MTF.jpg
I should add the fly in the ointment for the Tamron could be the bokeh at 600mm. The wide separation between the sagittal and meridional lines at 600mm could mean a harsher bokeh. usually good bokeh comes when these lines are closer together. it doesn't seem worse than the 150-500 however, so that may be a reference point.
Based on this alone the Tamron would be seen to be in with a good chance of being a good lens. It's bokeh doens't look like it'll be any worse and I've never complained about bokeh on my 100-400L...Show more →
Thanks for these MTF comparisons, it really looks promising.
If it really is in the same class as the Canon 100-400L, it will be a unique lens and high on my list.

+1.
The MTF also looks quite good.
Perhaps I was (fortunately) wrong in my earlier assessment.

If it have the same IQ and AF like the 100-400 lens, it would be fantastic for that price. I hope so but i can't really belive it. To get a 600mm lens with decent IQ for $ 1500 would be fantastic. And they would sell a lot of lenses
If it anywhere near as good as the 100-400, I predict a lot of used 100-400's on the market.
I hope it is as good, finally a long lens thats affordable for everyone instead of 200-400 lenses out of reach for most of us.

That's not bad for $ 1500 What speed does the EF 100-400 have ? 3 or 4?
Dear Lars,
Don't forget the other advantage the 100-400 has, the awesome 1- 2 stop IS.
Fanboys will always trash anything third party as is their right. What they will never understand is that their right doesn't make them right, as in correct.
There is a real market for this lens that Canon will never understand and that is the market of the hobbyist. Not everyone with a digital SLR has either the means or desire to spend $ 6000.00 plus for a lens that reaches to 600MM.
Will every image taken with this lens be stellar and worthy of publication in every journal known to man? Obviously, the answer to that is no, just as it is for every $ 6000.00 "L" that ever is used.
If you take pictures for yourself, and are not struggling to make money at it, you'd be foolish not to look at this lens.
One thing we all can agree on, the world is not short on fools.

Tim Murphy

I would think that since they have already released the MTF graphs and sample images that this lens is really close to release.
Remember, this isn't Canon we are talking about with their 1-2 years of developing the 200-400.
