Other than the better built and minor sharpness, what are the advantages of the Canon 24-70 2.8 II vs the Tamron version?


Bokeh?
AF speed and accuracy?
Colors and/or microcontrast?
Resale value?


Or is it purely Canon's "L" branding giving it the higher price tag?

I have a Canon 24-70 II and lately has been thinking of just selling it to fund the Tamron and use the spare cash on a Sigma 50 1.4 Art.

I'd also be interested in the answer to this question.

I only own the Tamron, but based on my research, the Canon has less "onion" bokeh (most situations don't have any onion bokeh on either lens, but when they do, the Canon seems to suffer less of it.)
I'm sure AF speed is faster on the Canon, although the Tamron isn't slow either.

Canon's resale value is a tricky thing since every now and then there are (used to be?) sales when you can buy the Canon for $1600-1700 as opposed to the $2400 normal price. So if someone wants to sell the Canon, timing is important and influences resale value.
However, now that Canon has implemented stricter price policy, those sales may be over (for a while at least). It means that you buy high and used prices are much more predictable.

I remember that I was flirting with the idea of buying the Canon when Amazon, Adorama, B&H had the double-dip rebates/sales and a new one could be had for about $1600 (after cashback etc.) while other were selling used ones on the forum often for $1800 and up. Seems like these times are over with the new price policy from Canon
But that's just my 2 cents.

I am totally satisfied with my Tamron, it is sharp, microcontrast is excellent and AF works great on my 6D even with the outer points.
And VC is very handy in certain situation in low light with static subjects. I know modern FF cameras have excellent high ISO capabilities but still, if you can take the same photo at say ISO 800 without motion blur with Tamron VC vs. ISO 3200 or 6400 on the Canon, the difference is significant. And even though the Canon may be a bit sharper, that small sharpness difference will not make up for the 2-3 stops in ISO difference (and the resolution drop, more noise and less dynamic range that comes with higher ISOs)

But some people may virtually never need VC, they shoot people etc. who move around where VC won't do a thing, and they obviously will never miss stabilization on the Canon.

The Canon has focus and zoom rings that turn the same way as the rest of the Canon line up. The Tammy turns the Nikon way. So if you are shooting MF video this is less confusing when you change lenses.

I tested both and ended up keeping the Tamron. For me it was the economically smarter choice :). I loved the fast AF on the Canon, and the Tamron is noticeably slower there, but not so slow that I'm missing a lot of shots.

The VC works well, I've heard folks say it's not needed, but I like it. Took the Canon to the circus and it was pretty dark in there, so a slower shutter and less ISO would have been nice.

I haven't needed to do any MFA with the Tamron, might do some more testing on that, but so far so good.
I've had a few shots with pretty obvious onion bokeh, but it didn't bother me enough to pick the Canon over it. Overall, I think it has very nice bokeh.

I'm happy with the sharpness of the Tamron, comparing shots with the Canon I don't see a huge difference, but I also haven't compared corner sharpness, where I hear the Tamron is lacking. It's sharpest at 24mm, but I think even at 70mm it's pretty good.
I've had some onion bokeh appear, it didn't bother me too much though. I think overall the Tamron's bokeh is pleasing though. Never had onion bokeh in the Canon, I think micro-contrast is a bit better in the Canon, too.

I think the Tamron is a good buy when a rebate is going on and using greentoe.com for an extra bit of savings. I've seen them used go for <$900, so I'm thinking that will stay as the used price. As PP mentioned, Canon's used pricing is all over the place, I've seen some go for 1800 and some for 1600. That will probably regulate once Canon's pricing scheme is fully in effect. I was all set to get the Canon, but then reconsidered because I can't justify spending that much when I have other lenses I use more anyway.

Both the Canon and Tamron are outstanding lenses IMO, and I'd happily own either one!

Ok, here is the "weakest" point of the Tamron, 70mm, 2.8
On a 6D
It gets a little sharper when stopped down. But even wide open, this is perfectly fine for me.

Canon mk2 - faster and more accurate AF and more expensive which gives you a sense of prestige

Yes, and after owing two copies of the Tamron, i'll add "works as it should" as well.
The VC system broke on both my copies within weeks. Sort of made it pointless having a VC lens with no VC really, so went with the Canon.

Unfortunately even if you took away the vc on tamron you still have a lens that performs almost just as good as the Canon for less than half the price. But for all the naysayers I say just include the time and cost of getting it calibrated from Tamron as part of the buying process and you should be guaranteed to have an excellent lens for the years to come.

I had no issues with actual IQ from my two, although the first was pretty soft on my 60D wide open. I never considered this an issue because I was never going to use it on that camera.
I did miss a few shots because the focusing was nearly as good as Canon, but not quite as good. Mainly the AF speed let them down in AI Servo mode on my 5DMKIII, but I also found they would miss the target more in low light. I tested them using FoCal and a few basic tests and could not find anything wrong with them in good light.
I also found the outer AF points were not as reliable on the first copy I had. The second was better but still not as good as the Canon MKII.
