Folks from America, Europe & Australia are lucky ... you can return stuff that you don't like ... it is not easy to return stuff in most parts of Asia (except maybe Japan, Hongkong, Singapore etc) ... the return policies in most parts of Asia 5cuks cow n!pples.canonian said:I also purchased the Tamron, used it for one wedding and returned it because it wasn't that sharp at 2.8 and also slow to focus.

Returing the Tamron 24-70 f2.8 soon. The AF on my unit is crap. There is a huge disparity in MF sharpness vs. AF sharpness regardless of AFMA which I tried all the way form -20 to +20. (Got better at +10 but no better at +20)... I wonder if all Tams are like this or just my copy.

welcome back to mrk II waiting room ;D........I hope you didn't cancel your pre-order
Why buy f2.8 lens when you can't use it at f2.8.
I wouldn't buy an f1.2 lens unless I intend to use it at f/1.2 ... I don't own one coz I do not need f/1.2 (at least at this stage).bdunbar79 said:Dylan777 said:K-amps said:Marsu:

Did I buy the 85mm f/1.2L II lens JUST BECAUSE it's a 1.2 lens?? Hell no!! I don't give a crap what its maximum aperture is, that is one sharp lens! Oh such a bad answer my friend. It's the quality of the lens that the 24-70 f/2.8L II will be, regardless of the widest aperture.

canon sucks on that part...
I totally agreeDylan777 said:I thought people buy prime lenses for one reason - large aperture/speed. Rule #1 - You can always step down the f-stops from larger aperture, but not the other way around.

Why do you think 70-200 f2.8 IS II is popular? fast AF & sharp at f2.8 maybe?
I thought people buy prime lenses for one reason - large aperture/speed. Rule #1 - You can always step down the f-stops from larger aperture, but not the other way around. Most lenses get sharper when you step down 1 or 2 stops, but if we can get sharp image at wide open....to me this is HUGE PLUSSSSS

The popularity of the 70-200 f/2.8L II IS lens has less to do with the f/2.8, but rather the sharpness of the lens over all apertures. I don't mean general sharpness, I mean supreme sharpness over many other lenses in that focal length range.
You should never buy a lens for ONE reason, ever. Besides, large aperture/speed are TWO reasons. Again, I stand by my comment, 99% of the 85 f/1.2L II owners did not purchase it because of the 1.2 aperture, but rather the supreme performance of the lens at useful apertures over other lenses.
There are tons of lenses you can buy for a Canon camera that have really wide apertures, but also which happen to perform very, very poorly.
You're talking f/stops in your post, which is fine, but who cares if the lens performs poorly? So I have mediocre photos at f/8 and crappy photos at f/1.8? Another scenario, suppose a prime has a widest aperture at 1.2. Okay, but if it's super sharp at f/5.6 and I only need it at f/5.6, I'm STILL buying it because it's the sharpest lens at f/5.6. I really am not concerned about widest aperture necessarily.
To support your point? Yes! I did purchase the 300mm f/2.8L I IS lens because I can go as wide as f/2.8, which is very useful for nigiht sports with fast shutter speeds. But I didn't buy the 85L because of it's widest aperture, I bought it because it's the sharpest lens at 85mm over all apertures, regardless of how wide it can go.

Get the EF 24-70 II. With no other lens in this aperture range you can focus so quick.
