Most of my photography is travel photo shoots. Mostly I use the kit lens which is an EFS 18-135 mm zoom lens. I rarely enlarge anything larger than 7” by 10”. I have published several books using Lightroom 6 software. Been generally very pleased with the results. My question is would I get noticeably better quality of photos if I switched to a more expensive camera body and a higher quality lens? New to this website and this is my first post. Steve
Hi Steve,
Your 80D is a 24MP APS-C DSLR with pretty good general specifications... unless you do heavy cropping or shoot in particularly challenging conditions, you're unlikely to see much improvement in image quality with an upgrade in the camera itself. There are some cameras with better AF systems if shooting fast action or heavily relying upon the AF system in other ways.... And there are some cameras that are more usable at high ISOs if you shoot a lot in low light conditions. But for more general shooting purposes, you wouldn't see much benefit from upgrading from your 80D.
Lenses are another story. While the Canon EF-S 18-135mm is a pretty decent and capable walk-around lens, it depends a little upon which version of that lens you have and you might be able to expand your capabilities with other lenses. The EF-S 18-135mm "STM" and "USM" versions appear to use identical optical formula, so should show little to no difference in image quality. However, between those two Canon claims the USM version is 2X to 4X faster focusing. That could make some difference if you are shooting fast subjects. There also is a third, older version of that lens... neither STM nor USM. That older version uses a slower, noisier and less accurate micro motor for focusing. It also uses an earlier, supposedly less capable optical formula. That 1st version of the 18-135mm is discontinued, so only the STM and USM are offered now.
Another difference between the 18-135mm lenses only effects video. The USM version is designed to accept a separately sold, optional power zoom module (PZ-E1?). In fact, it's the only lens that can use that module. That's an accessory with little relevance for stills shooters, but that might be useful for video.
All three versions of the 18-135mm have IS. Whether it's the same in all three, I really don't know. You might be able to find some info in reviews (check out The-Digital-Picture.com... Bryan extensively reviews everything Canon).
All three EF-S 18-135mm also have a moderately "slow", variable aperture: f/3.5 (wide) to f/5.6 (tele). This may be a limiting factor too... both depending upon lighting conditions and in depth of field control. For example, a "faster" lens like the EF-S 17-55mm f/2.8 IS USM gathers up to 4X as much light (f/2.8 is a two stop larger aperture vs. f/5.6). Also, a larger aperture can blur down backgrounds more to better separate sharply focused subjects... which can be handy for wildlife, candid portraits where you have limited control over the background, etc. For example, a Canon EF 135mm f/2L USM lens not only gathers 8X as much light as your lens zoomed to 135mm, it also can create very shallow depth of field and very strong background blurs...

Of course, the EF 135mm f/2L lens ain't cheap and isn't as versatile as a walk-around zoom like yours. It's also relatively large and heavy, though only slightly larger and about 8 oz. heavier than your zoom. Also note that the 135mm f/2 lacks IS.
Some other lenses can give similar effects for less money. For example, on your APS-C format camera the Canon EF 50mm f/1.4 USM and EF 85mm f/1.8 USM both are excellent short telephoto portrait lenses with strong background blur/shallow depth of field potential. Neither have the premium build quality of the 135mm f/2L, but they are both quite a bit smaller, lighter and a whole lot more affordable.

Other lenses may offer other advantages over your 18-135mm...
- EF-S 60mm f/2.8 USM and EF 100mm f/2.8 USM are both true macro lenses able to focus much closer and render much higher magnification, if close up and macro photography interest you. There also is the EF 100mm f/2.8"L" "IS" USM that adds image stabilization and even more premium build quality.

- EF-S 10-18mm f/4.5-5.6 IS STM and EF-S 10-22mm f/3.5-4.5 USM both offer much wider angle of view that can be useful for scenery and other things. While your 18-135mm goes moderately wide, while these two zooms going as wide as 10mm are pretty extreme. The 10-18mm is quite affordable, has IS and is reasonably compact and lightweight, but is pretty lightly built. The 10-22mm is an older, but still excellent lens that costs about 2X as much, but is better built and has faster (larger) apertures, but lacks IS. Not that IS is particularly necessary on ultrawide lenses. Image stabilization is nice on any lens, but tends to be a lot more useful on telephotos than it is on wide angles.

- Telephotos such as 70-300mm, 100-400mm zooms and/or 300mm and 400mm primes are invaluable for wildlife and sports photography. Of course there are even longer... 150-600mm, 500mm, 600mm and more. Prices might be intimidating though! Not to mention size and weight. There also are teleconverters that can be added for even more "reach", though they may only fit and work properly on certain lenses.

There can be other considerations effecting lens choices. For example, if you are a "street shooter" and want to remain pretty unobtrusive with your camera, a really small lens like Canon EF-S 24mm f/2.8 STM or EF 40mm f/2.8 STM "Pancake" lenses may be just what you're looking for. There also are specialized "Tilt/Shift" lenses for architecture and product photography (among other things)... Ultra high magnification macro lenses.... and much more.
Only you can say if any of these lenses might be useful to you. As you can see, what you choose depends a lot upon what you shoot, how you want to shoot it and what you plan to do with the shots. You've got a good "general purpose" zoom. Maybe that's all you need. In fact, you might be better served putting your money into other things... such as lens hoods for any lenses that don't have them (hoods protect the lens both from stray light and from physical bumps).... or maybe a good circular polarizing filter... or maybe a decent tripod.... or maybe for better organizing and post-processing software... or for another external hard drive to back up your images... or a monitor calibration device for more accurate image adjustments... or maybe to put gas in the car to go someplace you've wanted to take photos!
