Yeah, that lens is basically the talk of the town in all the hobbyist groups right now, totally agree on how fast it feels. Just to add a tiny point from what I've been reading in the community: * Tbh, the general consensus is that u really need to stay on top of the firmware updates to keep the eye-tracking working perfectly on the Mark III.
* Not 100% sure, but some reviews say the balance can feel a bit front-heavy on the R6 bodies, so maybe think about a grip if ur shooting for hours? Basically, the feedback from other owners is super solid, it just takes a bit more 'tinkering' than native glass sometimes.

Adding my two cents here, but what exactly is your main subject? I need to know if you're doing high-speed tracking or just stationary portraits before I can give a solid recommendation. I've been very satisfied with the signal throughput on the newer Tamron glass, works well with the R6 Mark III communication protocols. Quick tips for you:

• Make sure you use the Canon Mount Adapter EF-EOS R if you're using EF lenses, it keeps the weather sealing intact which is a huge plus.
• I've found that disabling the in-camera lens correction for distortion often helps with third-party glass performance, no complaints on the raw files after that.

> Tamron 150-500mm f/5-6.7 Di III VC VXD for bird photos. Its honestly amazing how close you can get to things without moving an inch I remember when I first started out with my first serious camera years ago. I was totally convinced I needed every single focal length covered to be a real photographer. I spent a literal fortune on a massive, heavy bag that mostly just sat in my closet because it was such a chore to lug around on hikes. Eventually, I realized that for my style, I just needed one solid, versatile lens that didn't break my back. The one I got back then was definitely a bit of a compromise on the aperture side, but it taught me way more about composition and finding the light than any of my flashy gear ever did. It is kinda funny how we all chase the perfect glass when sometimes the decent gear is what actually gets us out the door to take photos. I have been using my current setup for a long time now and honestly... I stop thinking about the technical specs the second I see a good shot. It just works for what I do.

I am still pretty new to the hobby so I am not a pro or anything, but I have been really enjoying the Tamron 150-500mm f/5-6.7 Di III VC VXD for bird photos. Its honestly amazing how close you can get to things without moving an inch... basically like having a telescope on your camera. Anyway, my main tips if you go with this one:

• keep your shutter speed extra high when youre zoomed in at 500mm so you dont get any blur
• maybe look into getting a monopod because it gets pretty heavy after carrying it around the park for an hour I am still figuring out how to get the focus perfect every time but the reach is just incredible for the price. Not 100% sure if its the best for everyone but it made a huge difference for my weekend trips. Hope that helps!
