I'm sure this is going to be a well improved lens over the current version, but the major trade-off: it's heavier at 825g vs 905g. Suggested starting price is also cheaper $100 cheaper than the MSRP of the current version, however there are some rebates at the moment that bring the price down. Depending on reviews, may be picking this up with a G2 70-200 at some point.

It'll be interesting to see the reviews of this lens vs the Canon and Sigma versions comparing the IQ and build quality. Does anyone know how well Tamron and recently Sigma's weather-sealing compare to Canon's?

This is one of the better and most thorough reviews of the Tamron 70-200 G2 and weather sealing is only briefly covered:
http://www.the-digital-picture.com/Reviews/Tamron-70-200mm-f-2.8-Di-VC-USD-G2-Lens.aspx

The current Sigma 70-200 does NOT have weather sealing, but I would guess there is a replacement on the way fairly soon which will include some kind of weather sealing.

Looks like the new Sigma 24-70 ART is only really "splash-proof" as they state:

Thanks. Looks like Sigma has only gone so far to protect the mount only for the 24-70.

Wish they'd make the zoom and focus turn the same as Canon and Sigma. I have the V1 and you get used to it but it sure would be nice.

This is why I ended up picking up a 70-200 G1 after purchasing a 24-70 G1. Needed the VC/IS in my 24-70 for video usage and simply was not many other options out there at F2.8 (or better). Considering picking up a G2 "set" to build a second kit if the reviews of this 24-70 G2 look good compared to the other options. Was holding off for a Canon 24-70 F2.8 with IS, but still waiting after all these years...

exactly. i find it equally puzzling and inacceptable that Tamron still is unwilling to build lenses with correct ring turn direction for the respective lens mount. if only one version, then why do they chose Nikon-style when canon mount/turn direction is by far the largest market segment/installed base of cameras. tamron's die-hard attitude on this is a sign of disrespect towards canon-users and shows a clear lack of business judgement.

personally i have sold my earlier tamron lenses mainly for the annoyance of wrongly turning zoom ring and missed shots in fast-paced situations and will not buy any (zoom) lens ever again that zooms the wrong way round. i care less about focus ring direction, since i never use manual focus ... but it is an issue as well.

Can someone please confirm if it's an old design in a new housing (which it seems like) or a new one (# of groups/elements match is a coincidence)?

G2 Lens:
http://www.tamron-usa.com/product/lenses/a032.html

G1 Lens:
http://www.tamron-usa.com/product/lenses/a007.html

MTF charts are identical. Optical construction (inside the housing) is identical. Believe this is mainly "just" new processing unit, improved VC (IS), and TAP-IN compatible (for adjustments & firmware).

May consider selling my G1 set for these G2's, or keep them around for a 2nd kit. REALLY would love to get a Canon 24-70 F2.8 with IS, but it doesn't exist...

Thank you! I would also love to see a stabilized 24-70 from Canon, but for now will probably go with the new Sigma.
