I am glad that I got Tamron 24-70mm VC. No more waiting...
And how do you like it?
I like this lens a lot. The IQ is sharper than my old Canon 24-70mm MK1. I think people complain that it might have onion bokeh. However, I haven't really seem that yet. By the way I am not a PRO, so I don't really think I will be so picky for the onion bokeh in few photos in my life. I really like the IQ and VC feature of this lens.
HOWEVER, if I was a PRO, I would just wait for Canon 24-70mm MK2. For PROs you are making money from your clients, so you should use the best gear for your clients.
I was definitely temped by this lens. It receives great reviews and considered at least on par with the Canon 24-70 f2.8 Mk I in terms of IQ and has VC to boot! However, having the zoom ring turn the opposite direction was the deal breaker for me.
I think you won't feel any inconvenience for the opposite direction for zoom ring. When you are turning the zoom ring, you will adjust the direction to the correct way. At least there is no problem for me.
