I was thinking of the Sigma 17-50 as an aps-c lens? Does it need to be cropped, either by the system or to deal with image circle issues? If cropped, then you're in territory pretty well covered by the 24-105/4? Likewise, if you add a 24-70/2.8, it duplicates much of the 24-105 with the f2.8 aperture .

Which would suggest the two wide zooms xx-35 add a focal length range you don't cover yet. (If the Sigma's not a crop lens, then it covers the focal length range that you propose from the new wide zooms. ? My impression (I'm a Sony user) is that the Canon dslr lenses adapt well so you might need to look closely to what both lenses offer to see if you want to go with the adapter. Which would also be available for other lenses that might not be conveniently available in the new mount, too.

My first impression/suggestion would be one of the two wide zooms for new focal length range coverage. That said, the 24-70 range is extremely useful and popular and you might find both of you want/need it simultaneously if you only have the one lens in that range?

Perhaps spend a little more time seeing what seems "missing" from your kit.

I was in the same boat as you lately. At least you didn't have to go through choosin a system. I ended up with Canon mainly for their tiny 70-200 2.8 which is one of my most used lenses especially durin travels.

In my opinion check out the EXIF data in lightroom and see how often do you use wider FLs than 24. If it is more often than you use FLs like 50-70mm then go for the 15-35. If not then go for the 24-70

Another method that helped me a lot was with makin a chart of FLs ranging grom 14 to 200mm (and another for 200+mm) and looking for te EXIF data on photos i am interested in and liked on sites like 500px and flickr. That way i had some more data from places that i wanted to visit and perhaps some compositions that i liked in particular. Based on that more than 60% of my photos were shot between 24 and 70mm with another 25% between 70 and 200mm. Wider than that was only 12% and 3% for FLs above 200mm (mainly up to 400).

I ended up choosing 24-70 2.8 and 70-200 2.8 for my travels. I thought that if i wanted wider i could stich a panorama or if i wanted more zoom i could crop to about 320mm with about 16mp. Plenty for me and with some more room for a bit more crop in post. I dont shoot a lot of astro so an ultra wide was not a problem for me.

My 2 cents: get the 24-70. It will cover you for the most part. In the event you want wider you can buy the soon-to-be-announced 16mm f2.8. It probably wont be as sharp as the super expensive 15-35 but it is a prime and fairly bright and above all inexpensive (some say for a price ag around 300$). If you want all RF. If not you can probably buy an older DSLR lens and adapt it. Another option is to rent to see which one you like better and how often do you reach for one or the other.
