Great info, saved!

But honestly, what r u actually planning to shoot most on ur trips? Like, is it wide landscapes or more street photography? It makes a huge difference for what you should carry! One thing to watch out for is that some people suggest lenses that are actually for mirrorless systems, and they won't even fit ur 5D Mark IV mount properly. Basically, I'd just stick with any of the first-party Canon glass. You can't go wrong with their pro-grade stuff because it’s built for that specific EF mount and the weather sealing actually matches up. Tbh, I've had some third-party lenses that felt a bit loose on the mount or had weird autofocus glitches on the newer bodies. If you want it to just work without worrying about firmware or fitment, just go with Canon and you'll be fine!!!

Nice, didn't know that

> What's the sharpest travel lens for my 5D Mark IV right now? Just catching up on this thread. Honestly, for a 5D Mark IV, you really cant go wrong if you just stick with the first-party Canon L-series glass. Ive been extremely satisfied with their professional zooms for years now. They are built for reliability and the weather sealing is a must for travel... no complaints at all regarding the build quality. The biggest thing to be careful about is compatibility. You have to make sure you're looking at EF mount glass specifically. There are so many newer mirrorless lenses being marketed now that simply wont fit your camera body. If you stick to the high-end Canon zooms with the red ring, you get guaranteed compatibility and professional sharpness without the risk of third-party autofocus issues. Just find a solid professional zoom from Canon that fits your focal length needs and you'll be happy with the results.

Been rocking a Tamron 24-70mm f/2.8 on my 5D Mark IV for years. Super versatile. Image quality is excellent, though be careful with distortion at 24mm. I'd suggest checking out used models; you might save some cash. Make sure to inspect it closely before buying, though! I've found it reliable.

Sigma 24-70mm f/2.8 Art. Chromatic aberration controlled, decent sharpness, around $1300. Depends on your needs though.

Tamron 28-300mm is decent, versatile, and leaves cash for gas. Image quality's not *stellar*, but practical.

Been happy with Tamron's 24-70mm f/2.8. Market shows consistently good reviews for sharpness and reliability since ~2017. Worth a look!

Hey! Sharpness is key, but think SAFETY first! Lugging heavy lenses while traveling? Ouch! Consider the Tamron 28-200mm f/2.8-5.6 Di III RXD. Super versatile, light (575g!), and great image quality. Less weight means less strain, fewer accidents. Trust me, a comfy photographer is a safer photographer! Happy shooting!
