the Tamron is much handier than the Canon and makes a highly valued and solid impression. by a locking switch, the tube when reassigning the camera can not be extended by itself.
With a front or back focus I have objectively at my no problems. the AF focuses quickly and exactly where he is supposed to.
the company-wide maximum aperture of 2.8 can also impressively good available light-photos in good quality.
the usd engine is fast and quiet.
at f 2.8 a very nice and sharpness on the precise blurred with beautiful background bokeh is great succeed.
The picture quality is starting up F3.2 very good, extremely sharp and contrasty and is from 4.0 to aperture diaphragm 10 almost too sharp
(I mean that you can get even worse with the models in portraits, because the facial lines are shown to good :-))
even at 70mm focal length is still crisp sharp photos can shoot what was already quite critical with the canon counterpart.
the color display looks very natural
and the stabilization works absolutely brilliant, really very effective.
I mean, he's even better than the than the IS in Canon EF 100 / 2.8 / L / Macro / IS / USM
... And that's really saying something.
However, I am spoiled by the image quality, the cracking of the sharpness and color brilliance of
prime lens: Canon EF 100mm / 2.8 / L / Macro / IS / USM, or the zoom lens: Canon EF 70-200mm 1: 4,0 / L / IS / USM,
and it's probably very difficult, as almost-perfect as those two to find something comparable objective. but I think that you see such a well should not do (the would then probably as with the apples and pears)
now I ne` lot of photos with the Tamron shot ... and tried everything possible again.
the longer I am dealing with the objective, the clearer it becomes how "great" this glass is.
I'm really happy to have taken this step and realize more and more to appreciate the super quality.
the Canon 24-70mm is better No way ... and has no stability.
let's see if the can successor beat this Canon Tamron.
Nevertheless, it also has no stability ... and costs more than nen` thousands more than the Tamron ... and somewhere hears it then they're on, I find ... :-)
Well, all in all I'm extremely pleased and have probably finally a new "always on it" found ... namely with image stabilizer.
I think the Tamron SP 24-70mm F / 2.8 Di VC USD managed for absolute and highly recommended ...
..and if it were, then I would give it 6 stars also.
