I've decided to wait and see what Canon does with the 100-400L replacement.  It's way, way, way long overdue and I'm pretty happy with my 70-200/2.8L IS II + 2xTC III combo.

Bryan makes the same mistake as many other reviewers by measuring the focal length at close range.
At close range zooms "loose" focal length more rapidly than primes.
If he had only focussed say on something at a couple of hundred metres I am sure that the 570 he calculated would be much closer to the 600 of the prime he was checking against.

I'm not sure it was a 'mistake'.  One would hope that testing at or close to infinity focus would yield a result of 600mm, within a reasonable rounding error - that's how the focal length sepcification is defined.  A 600mm lens at 200 m frames an area of 12 x 8 m - most of us shooting with 600mm lenses don't shoot houses from 1/8-mile away.  What a typical user would care about is the effective focal length at a typical subject distance (and a 600mm lens at 10 m is a 'typical' scenario for birds, for example).

If for AFMA it is advised to set the target at 25-50x the FL, I would use the same distance for this sort of measurements. That makes 15-30m for a 600mm lens.

I like Bryan's reviews but he is isolated in his suggestion to shoot at 500mm and upres. I find the lens plenty sharp at 600mm f/8 and never found the need or the convenience to do as he suggests. Other users/reviewers seem to be of the same opinion too.

I also have to say that I envy you for shooting birds at a typical distance of 10m. I rarely have the chance to get that close except for ducks, geese and other very tame birds in city parks and the likes. In fact I would say that 20-25m is more like my typical working distance.

I too went to the how at the NEC and tried it out on my 5D3. The review says its soft at the edges at 600mm but what do you use 600mm for I use my 400mm canon for birds and motor racing so soft ate the edges is not a problem included is a full frame I took at the show 4000 iso the other pic is a crop from the same frame.

The exif shows f/5.6 @600mm ???

I'm often further away than 10 m, distances of 15-25 m are more common.  But at those distances, I'm shooting with an 840mm or 1200mm lens.  Around 55% of my shots with the 600 II are with the 1.4xIII, and ~30% are with the 2xIII.

Thank You for the links.  Reading the one via google translate was fun: a lens having a necklace is a funny image.  :P

:) I can translate it if you want, i'm the writter for Pixelistes french website. But, i don't want to make advertizing for the website. I'm also a photographer who wants to discover things. So i take my usually nickname "Djenuwine" as i use on Instagram and things like this, and i just put a link to add informations and sample pictures taken with it.

Thanks for the offer but I don't think there is a need for you to spend extra time.  The google translation did a remarkably fine job and is only a matter of pasting the url.

I thought this review was over the top and somewhat uncritical.

Interesting.

The Tamron at 400/5.6 looks a lot sharper and contrastier than the Canon 100-400 at 400/5.6
However, the Tamron at 600/8 looks weaker than a Canon 100-400 with a 1.4x TC

So, by inference: will the Tamron at 400 mm with a 1.4x TC attached outperform a Tamron set to 600 mm without the TC?

i gave it a try, nothing scientific but i have been using the lens for a while so i know what it looks like at 600, with the kenko 300 pro 1.4x at 400  it looks pretty good but not better than the bare lens at 600 and the af does not work very well at all. the lens wont fit on the canon 1.4xiii.

I bought a new Tamron 150-600mm f/5-6.3 lens a month ago. I am a professional photographer and am not biased towards or against Tamron vs. Canon, as I own prime L-grade lenses from both companies.  Unfortunately, this lens is not weather sealed, and after using the lens for two weeks outside, the amount of internal dust was atrocious.  Regardless of being meticulous and using a blower at all times, the lens quickly absorbed dust onto the frontal glass element internally, including moisture, via the cork-screw barrel that retracts into the upper chamber.   Closely inspecting the markings on the lens, I saw that it was manufactured in China, as opposed to Tamron's traditional Japan manufacturer, which was a big shock, so quality control has definitely been compromised in order to sell the lens at $1069 :-\.  In the end, the build quality really comes down to the poor engineering design from Tamron.

Additionally, image stabilization for action shots (specifically bird shots) is not reliable.  Even though the proper autofocus point speed and tracking can be adjusted in the Canon 5D Mark III to compensate for the lag, shutter speed has to be at least 1/2000th+ of a second in order to prevent motion blur for hand held action tracking shots (coupled with f/6.3 on a cloudy day and ISO 1000-2000, this creates photos worthy of entry level DSLR bodies and stock lenses - which means not good!). Unlike my Canon 100-400mm f/4-5.6 L lens, which has 2 modes of image stabilization and creates very fast and stable shots, the Tamron 150-600mm lens only has one on/off VC switch with no additional stabilization mode selection settings.  Gimbal shots are naturally improved, but AF adjustment at 15m to infinity is still sluggish when trying to focus on objects 200ft and further (creep still occurs with the limiting switch).   I called Tamron directly, and their technical support team confirmed that their teleconverters are not compatible with this lens as Tamron engineers have officially discontinued all TC's and did not design this lens with the 1.4x or 2x in mind.  Additionally, they confirmed that both converters should not be used with the lens, as unpredictable results can occur and are not guaranteed to work properly. 

Static shots are amazing with very comparable MTF chart optical clarity to Canon, and portability of the lens is great :); nevertheless, I need a telephoto lens that is fast, reliable, and has excellent build quality for shooting Ospreys, Eagles, King Fishers, Herons, etc. while panning for fast track motion.  Sorry everyone, but this lens is not quite the "big white killer" that many individuals thought that it would turn out to be.  I too thought that this was the lens that would allow me to save several thousand dollars; however, I have now returned the Tamron 150-600mm lens for a full refund and consequently have to save up in order to purchase the real Canon 600mm f/4.0 L II (weather sealed, improved pre-set focus ranges, stabilization modes, etc.).  On another note, even though the "Sigmonster" 800mm f/5.6 is less expensive than the Canon 600mm, I am not even going to touch it, given that it too is not weather sealed and that other professional birders have complained that the focus ring breaks over time, has a fragile body shell, and is extremely sluggish to maneuver; being confined to a gimbal for the majority of the time.   In the end, you get what you pay for! :-\
