Upgrade from Tamron 24-70mm f2/8

[manl4747]

First, I am considering getting a newer canon body (currently EOS5Ti) and not sure what to upgrade to but looking at EOS 80D. 

With that said, I currently own a Tamron 24-70 mm f/2.8. I love this lens but was wondering what would be an upgrade or what would give me the same abilities to have wide focus capability? I really like this lens but it is so heavy and I mainly photograph travel pictures of buildings, nature, etc.

 If you think the camera/ and lens combination is a heavy weight on the camera strap around your neck, you're correct.  I only use a camera strap as a safety mechanism, in case I drop the camera for some reason.  You may want to consider a sling type of strap, which goes over the shoulder.  I use a Back Rapid Sport, but there are less costly straps.

Most high quality DSLR lenses have a little weight, especially the full frame lenses.  Any upgrade would likely be just as heavy, if not heavier.  A good upgrade candidate would be the Canon EF-S 17-55mm f/2.8L IS USM.  It is a "heavy" lens, which is currently on sale at clearance prices.  I just ordered one as holiday gift for someone.  The 17-55mm range is better suited for walking around with an APS-C body like the T5i, or an 80D

But, is there a particular focal length that you use most often for your travel pictures?

Agree with everything wadizzle said and then some.  The Canon (24-70) is the lightest of the bunch, since it doesn't include IS.

Both the Tamron and Sigma (which I have) are hefty due to this addition.  My sigma is the heaviest of the group.  It doesn;'t bother me however.  I also use a Sports Breathe for daily carry. 

If you are going to stick with APS-C, then buy the 90D and a APS-C specific lens.  You'll be able to sel lthe G2 easily to offset the purchase.

" A good upgrade candidate would be the Canon EF-S 17-55mm f/2.8L IS USM. "

This is not an upgrade from the Tamron 24-70mm f2.8.  So, forget that, it is more of a even trade if IQ was your goal. And, if weight is, it is also pretty close.

"I really like this lens but it is so heavy ..."

Perhaps a different camera format is in order. Check out the P&S line. For instance the Canon PowerShot G5 X Mark II Digital Camera.  There are others, too.  They have almost every feature, even more, than your T5i has and are smaller and lighter.
