There are several reports, including from Neuro, that the 100-400 is at least on a par with the 70-200 + 2xTC, though he is reviewing that.

Actually, I'm confident that (for my copies, at least) the 100-400L @ 400mm is very slightly better than the 70-200/2.8L IS II + 2xIII in lab-type testing, and the two are not really distinguishable in real-world shots.
Interested to know if you have done the comparison with the 400 f/5.6 neuro. I recently took the 400 f/5.6 and 70-200 f/2.8 II on safari and the 400 was noticeably sharper than my copy of the 70-200 with 2xIII, unless I had the latter at f/8 or smaller.

anyone else see the MTF charts here on Tamron's Europe site? Any thoughts??

that's a pretty big discrepancy in 30 lp/mm curves between sagittal and meridonal at the long end as you go away from center.
Doesn't that make for some annoying aberations and grungy transition bokeh?
Despite that, will wait for some tests to see if it outperforms my old 100-400. If so, then the last "L" in my quiver might hit the market.

I like third party producer for their different lenses.
And I hope, it will be a good one.
If so, and I am not in a hurry, I wait for comparision between this and the newer version of the 100-400L.
Ah, good times.....

No, in September, but July should give me time to either get the lens if it is "good enough", accomodate any shipping delays, or shop around for good quality 100-400L

Fortunately for me, I'll probably get a chance to use and review it from Tamron before I have to make a decision.

Fortunate for us too! You're a good reviewer, Dustin.

I concur. I look forward to reading Dustin's review. I own the 200-500 Tamron.

No guarantees, but I was told today there is a possibility that I might get time with a pre-production model to review to coincide with the release. That tells me that the release is going to be sooner rather than later.

I'm not an expert on MTF charts, the divergence in the 600mm curves doesn't look to good, but I don't have comparisons. Also, I'd be happy if the best performance of the lens is in the 350-450mm range which is what I was in the market for originally. I'd try to hold back on shooting at 600mm, just like avoiding shooting wide open. I found on my 100-400, pullling back to about 380 helped

No matter how interesting this is everything proper over 100mm is way to expencive for the normal person with a normal income...
There is NO way EVER i can spend more then 450 bucks on a lens even tho i know oits sweet stuff its just way to expencive im not gonna pay 3 times my monthly income on a lens like this or the 70-200 IS II or 100-400

extended bandwidth coatings, dang! who doesn't want that? i read through the press release and looked at the sample images, they are small size but still look pretty good. what i like is that it weighs half as much as my sigma 120-300. does the lens itself extend when zooming or is it internal?
