[Canon Rumors]

Tamron has officially announced the 17-70mm f/2.8 Di III-A VC RXD for both the Canon RF (RF-S) and Nikon Z mounts. This lens is for APS-C sensor cameras such as the EOS R7 and EOS R10 and has a 35mm equivalent field of view of 27-112mm. This lens is going to find its way onto […]

17-70 1:2.8 Wow
Stabilized Wow
530 g versus 645 g (Canon EF-S 17-55)

Now I will spend a lot of time whenever going out: which lens to throw into the bag?
Sigma 18-50 1:2,8 (light)
Sigma 17-40 1:1.8 (bright)
Tamron 17-70 1:2.8 (reach)

And even the price (MRSP) sounds fair!

First German price:

649,- € (incl. VAT) WOW!

This is great news! About damn time.

The zoom range would have been very welcome, but it's come too late and I already have the excellent Sigma 18-50. That plus the (admittedly minor) inconvenience of rings which operate backwards for Canon users mean I won't be taking up Tamron's offer :-(

This is really a big deal, providing it's optically sound. The lens that Canon should have made right off the bat really, but they seem to have no interest in providing reasonably high-end solutions for APS-C shooters. My friend has an R7 to replace one of her crop Nikon DSLR bodies that failed (after some 250,000 actuations), since Nikon doesn't even have anything close to the R7. I gave her my 18-150 to try, but she gave it back because it felt flimsy. She opted, instead, to get an adapter and use the EF-S 18-135 USM, which optically is pretty good and has the advantage of feeling quite sturdy. The USM is the last rendition of that focal length range, and is optically better than the first version.

Where did you get the "schematic drawing" for last couple of lenses featured here? Previously, they looked real and made sense. Just look at this one: according to the illustration, all the lenses are positive, equally thick, equally spaced. Even my window panes show some variation. Is this AI slop?

About lens image quality:
I looked at https://www.the-digital-picture.com for a comparison of the Tamron and the Sigma 18-50 C.
You can get one with the Sony Alpha 1 which I shared here with the link above.
My impression (17/18 - 50 mm):
Center sharpness quite equal
Sigma much better in the corners
Tamron significantly less vignetting.
YMMV

Nice addition to the endless sea of options but special in the standard zoom category!

Just learning to like the EF-s 15-85 for time lapses after understanding how to optimize focusing (manually, after each change of focal length is important!). It is a very sharp and contrasty lens and allows to use a variable ND filter adapter which is very convenient for video.
Maybe a good option if I need constant aperture by design for video zoom ops so I will reevaluate the need - the EF-S 15-85 goes from 3.5 to 5.6!

Long overdue, I’m still confused why this wasn’t Tamron first RF mount lens first since it has no true direct competitor from Sigma (the 18-50 trades stabilization and focal range for compactness). I no longer have interest in this lens since I have an R7 and Sigma 17-40mm f/1.8, but this will be a very compelling option for R100, R50/V, and R10 owners, especially those interested in handheld video.
