I can only speak for the Tamron 16-300. I use this lens on the Canon 80D and it produces very satisfactory results for me.

And I'm very happy with my Sigma. I understand the zoom rings rotate in opposite directions.

I have a Tamron 18-400 “on hold” to check out tomorrow at a local camera store to use on my Canon Rebel T7i. I was concerned about the sharpness, but most reviews are very positive, so I want to try it first. If you have flexibility, have you checked this model? Locally it was only $20 more than the 16-300.

They are good useful lenses. Not going to be the sharpest tack in the box (like a prime), but very useable across a wide zoom range, and they focus quite close for near macro look. Generally not quite as sharp in the last 100mm, but that seems to vary slightly by copy from what I've read. Related - I recently bought the 18-270 Tamron version from a very nice Pro (lady from San Diego) who used the 18-270 in her business. I viewed some of her work that she claimed was shot with the lens it looked very good, and she makes her living from her studio.
The lens - It had jammed (zoom jammed due to the zoom guide screw/bushing coming loose and falling into the tubes - fished it out and remounted, w/o disassembling the lens, and it works like new, even cured the lens creep).

For general work I have several 28-300, 18-250 and 18-270 Tamron and Sigma zooms (Nikon and Sony mount)..... I wouldn't mind having the 16-300 or the 18-400, and I wouldn't turn away an 18-300. They are decent for a wide range of shooting. There are some great deals online, and take a look at MPB.com, KEH, UsedPhotoPro, B&H, Cameta and Adorama, Hunt's and Samy's for a good used deal with a return policy and usually at least a 6 month warranty. Or you can buy new.

I have the Sigma 18-300. Only thing I noticed is some barrel (or pin cushion?) distortion at the lowest focal length when shooting short distances. I bought it over the Nikon because it's lighter. Lens has been fine, even in some sort of dusty places.

We love our 18-400 Tamron. Yes, we've read about lack of sharpness but can't find it. It really does a good job for magazine, book, and wall-hanger photographs. Take care & ...

Thanks for your comments. I hope to use this traveling to avoid having to change lenses on the go. I shoot for fun and memories, not professional. Learning from my local camera club and enjoying it!

The Tamron 18-400 is my "walk around lens." I've heard about lack of sharpness, but I have yet to find it. AF is fast and quiet. Basically, I use the rule of thump when shooting at long focal lengths. Shutter speed to match(closely) the focal length.. Not a prime lens, mind you, but if money is a concern, this is a great lens.

Does anyone use either of these lenses for VIDEO work? I film kids sports events for family use. My concern is focus speed. I'm using a Canon 70-300 II which is a great lens until the kids get close to me. I need something wider. My Canon 18-135 does not have enough reach when they are across the field.

Image quality for sports video use is not as important as focus speed.

Thanks in advance.

Okay... I'm confused. Tamron doesn't make an 18-300? They do make a 16-300 and the Sigma 18-300. Both are APS-C lenses. Other than the slightly wider Tamron, I didn't see much difference between the two after renting both. A previous poster mentioned barrel distortion on the Sigma. I didn't see it or if I did, it was easily corrected in post. However, the Sigma is available new for about $400 and the Tamron about $630. I can't address video....
