I totally agree with you, the difference is quite massive. Something is not right with either test parameters or with the lens. I would like to see The Digital Picture set of standard target shots in order to do the judgement. Let's see what transpires.

If my Canon were that soft, I'd send it in for service. I'm not seeing this as a valid comparison, as mine is razor sharp at that distance without sharpening.
I am very glad to see Tamron giving Canon a run for their money! But not a good copy of the Canon, or something was off in the procedure.
disclaimer : i still prefer lab test for reference , we are not professional lab test guy / lens owner so we perform short test and return the lens within the time slot (count in hours actually , gonna rush)
actually the canon wasnt that bad on my 5D mk3 , because of the limited time and location we can only do some test in rush , we can borrow the lens again next week so we can do the 200mm test which we crash up the file in accident +__+
not sure bad copy or the my canon optics need some calibration , do AF / MF / liveview focus but wont help to improve the the shaprness
i wont be surprise if tamron win in the shaprness test because it was designed under new standard and the cannon are old standard (i mean design resolution requirement / lpmm / MTF )

from the boring MTF chart you can see the advantages (although 30 lp mm was outdated and meaning less but you still see it kept as a good position )

and this one canon (yea boring MTF still told something , at least resolution and possible some characteristic of the lens )
compare two MTF , i wont surprise tamron win if you gonna pixel peeping +__+
if using both lens on canon 5D MK3 the different will be much less because the cmos wont contain that much pixel. just like sigma 35 1.4 art vs canon 35 1.4 vs canon 35 1.4 II , sorry but for some "silly" spec like resolution test , the new lens usually win.
for color , out of focus quality , i dont have big comment on the canon versus tamron , both dont have strange onion ring or swirly bokeh ball , they render stuff in quite similar way too
one more thing , shaprness wasn't that important to most photo and blurry corner may produce a effect that "looks contrast" due to the framing , usually we placing out of focus area on corner especially portrait work , ok now who need to care about the corner sharpness +__+ (for landscape guy or photo merge people , border sharpness improvements will help , do it )
capture something good is more important than made a pixel peeping sharp photo .
not all people need to buy this lens but if you got a hunger pixel monster camera and you want to do more cropping or over sampling work , you can consider buy this lens as it can feed the monster cmos
if you were a photographer who don't do a lots of pixel peeping / did not own monster camera / already own 70 200 / i would suggest you spend money on other stuff like light modifier or use it for a trip

) of the Canon know that Frank's images are not representative, and in fact approach deception, perhaps to make the Tamron shine a bit brighter. Or he just has a copy with a hazy front element.
