Thanks, and thanks to everyone. It is nice to know that the lens that fits on the 80D will also fit on the T series cameras. If that is the case I will be getting the lens. Then again, I might just wait and before too long just get the 80D camera. I will also consider the Sigma. I assume the Sigma and the Tamron have roughly equal quality?

Since when is the recently released T7i expiring technology? The alleged rumor that a T8i is coming is just a rumor, and likely a long way off. The 80D is older than the T7i and the 77D, and will likely be replaced much sooner. Canon will not be abandoning the Rebel line because of mirrorless just after releasing their first full frame mirrorless camera. I think you may be jumping to conclusions here that are unwarranted.

I don't subscribe to the idea that we absolutely have to have the best and latest as soon as it comes out. Unless of course, your income depends on it. I get great pictures for the most part with the T3i. It just isn't great for distant mountains and such. However, it is nice to upgrade from time to time. If the T7i works better for me, that is a good thing. I have no doubt there are even better cameras are out there, and in time I might be getting them. I have to agree with what is posted here. I can understand people wanting the best however.

I also have a canon 55 to 250 lens. I find it works great unless you try to use it at levels greater than 175 magnification. It loses quality at the greater magnifications. That is why I am thinking about a Sigma or Tamron, and may just stick with 18-135, not needing greater magnification than that. (Actually I might at times, but anyway...)

Thanks to everybody for all the information.

I would suggest since you're already shooting with Canon cameras, when buying lenses you should purchase EF lenses opposed to EF-S lenses. That way should you switch from Canon Crop Sensor cameras to Full Frame cameras you won't have to re-purchase your lenses. And I'm a stickler for Canon lenses for Canon Cameras...the glass has a higher quality to it than the Tamron and Sigma lenses. "THAT'S JUST MY OPINION AND PREFERENCE."

It would be unusual (though not impossible) for a kit lens from any major manufacturer to have a problem with distant backgrounds. You didn't indicate what the problem is, but I'm guessing it may be focus? You can do a lens test yourself (Google it, and see below.), or send it out to be tested. The solution may be as simple and inexpensive as having the kit lens repaired or replaced. Kit lenses are sold by the hundreds on ebay and elsewhere, and they are VERY inexpensive. BTW, a terrific repair place is tempecamera.com in AZ. Try one of these options before you empty your pockets.

Just purchased the T7i in a kit and it came with the 18-55 Canon lens, and the Tamron 70-300 also. This is my first DSLR so not up on what is quality and what is not. Read many reviews on both lenses, Canon was good+, and Tamron was favorable, some more advanced users had issues.

Enjoy! I am sure you will like it.

The Tamron 70-300mm VC USD costs $449. The Canon EF 70-300mm IS USM "II" costs $499 and has noticeably better image quality at 300mm. See for yourself: https://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=757&Camera=453&Sample=0&FLI=4&API=1&LensComp=1077&CameraComp=453&SampleComp=0&FLIComp=5&APIComp=0

In fact, the original Canon EF 70-300mm IS USM is still widely available for $377. It's image quality is more similar to the Tamron, though: https://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=757&Camera=453&Sample=0&FLI=4&API=1&LensComp=358&CameraComp=979&SampleComp=0&FLIComp=4&APIComp=0

If you want a somewhat lower cost lens and can use a slightly shorter telephoto, the EF-S 55-250mm IS STM is a pretty darned good option, too. Image quality is very close to the best of the Canon 70-300mm lenses. https://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=1077&Camera=963&FLI=0&API=0&LensComp=856&CameraComp=963&SampleComp=0&FLIComp=5&APIComp=1 The 55-250's STM autofocus won't be as fast as the USM on the 70-300s... The latter would be better if shooting action sports or fast moving wildlife... but STM can be fine for everything else. The EF-S 55-250mm IS STM is selling for $299. It may be offered in kit with the T7i for a bit less.

One lens to avoid is the Canon EF 75-300mm "III", which is often available for $200 or less. All the above lenses are better in almost all ways. The 75-300 has slow, noisy micro motor AF (not STM or USM)... lacks IS.... and has the worst image quality of the bunch, especially at 300mm. There is a version of it with IS for about $50 more, but it has the same poor image quality and slow/noisy AF.

I don't know what kit lens you got with your T3i... I think there have been 3 or 4 different EF-S 18-55mm. You can use the above website to compare them, but I suspect there's little difference. There are other, but much more expensive "standard" or "walkaround" zooms you might consider, such as the EF-S 17-55mm f/2.8 IS USM or the EF-S 15-85mm IS USM.

I had the Tamron 70-300, and loved the VC, but replaced it with the Canon 70-300 IS II USM. Turns out, the Canon's IS is considerably better than the VC on the Tamron, and the IQ of the Canon is definitely better, too. Win-win for me. I'd definitely recommend the Canon over the Tamron; it's worth the extra $50.

I'd say he could definitely be happy with the 55-250. I've not had one, but I keep seeing posts about how good it is, and they're available widely used. He could probably find it for under $300.

Had the 75-300 Canon. Definitely would avoid that, yep. No IS is not a good thing, and the CA and IQ in general were not much to write home about. For what they want new, he should just get the Canon 70-300.

I have the Canon 15-85. Very nice, but find it used where you can and save a bundle. I got a really good deal through Amazon for one in really good shape. The worst thing was the lens creep, but I've fixed that with one of those silicone bracelets that thinks it's a Lens Band.

I have the Canon T6i with a Sigma 18-250 that I use as a walk around lens.Very good combination.
