Sigma 70-200mm F2.8 DN Sport vs Tamron 70-180mm F2.8 G2 | Which is the Best Bang for Your Buck?

I love the format where you complete the overview with recommendations and then do optional deep dive. Excellent. Especially with chapter markings.

What an awesome comparison. Thanks for all the work you put in for this. I wish you continued success. I will try to get the Tamron eventually, based on this information.

Great comparison video. Thank you Justin. I look forward to all your videos with great anticipation. I own the original 70-180 and it has done a great job for me. I had a chance to shoot the G2 version of the lens. The advantages of the G2 are many comparing the two Tamrons. The G2 has better corner sharpness along with VC and the surprise macro feature. I think both lenses are great alternative to the Sony GM II which is the king!

I haven’t owned a 70-200mm F2.8 in years because I got tired of avoiding the weight and strain over a long day of use. I ordered the Tamron as soon as I saw the size and weight of it. Thank you for showing that it’s a strong choice. I never buy Sigma lenses since they always end up being way too heavy at any focal length.

Thank you very much, this is what I was waiting for! :)

That was very good compartion video. Thank you!

Great Video as always. Thank you and greetings from Germany

Thank you for creating this thorough review! Interesting results seeing how great both of these lenses seem. I've been considering the Tamron since they came out with the G2 for a relatively inexpensive option for some amateur indoor sports work. I'm also toying with the idea of the Sony f4 G mark II, even though you lose some light it looks like an excellent lens. And now the Sigma looks like a compelling option. I currently have the Samyang 85mm f1.4 mark I, and I really like it, so I was also considering their 135 f1.8, although I worry that the autofocus motor might be lacking even though you could potentially get some faster shutter speeds.

THE greatest camera/lens reviewer on the internet, ive purchased all of my gear over the years on his trusted reviews, he never lets me down. Love this channel.

Would love a followup value/performance comparison like this, but adding the Sony f4 "macro" 70-200 into the mix

Thank you for your great reviews.

To me, the size & weight win it all for Tamron, regardless of the rest of the features or performances. The Tamron is more than good enough in all other aspects.

I've been waiting for this comparison ! Many thanks Dustin for creating it. It seems that Tamron is punching "above its weight". I really hoped that the Sigma would be smaller and lighter. I really like the idea of a tripod collar and aperture ring, but the weight and size is just too much in comparison to the Tamron. Either lens however gives the Sony 2.8 a run for its price tag... wow, it's really steep !

Hi Dustin, thanks a tonne for these amazingly thorough and detailed reviews! One question: I think I briefly saw you include a snapshot of the Tamron 70-180 g2 mounted (from the camera's tripod plate itself) on a tripod. Given that this lens doesn't have a natively designed tripod collar, would you say that one can get by (e.g., due to lesser weight of the lens) with mounting just the base of the camera on the tripod, and not worrying about the torque pulling the ball head down (say, when the lens is extended all the way to 180mm)? Or, would you say that for tripod work, an aftermarket solution (which of course, takes up space, adds weight, etc) is a necessity, e.g., for the longer exposures and/or at the largest focal lengths? Thanks a lot!

I’m thankful the tamron g1 existed as it was my gateway into the focal range. I definitely couldn’t justify the gm back then. But after recently getting the gmii (tc, weight, focus speed, etc) there’s definitely no desire to opt for the sigma. The clunky hood needs a replacement asap.

Thank you for providing the comparison. It was very informative. I believe I'll choose Tamron. The difference in image quality is minimal, and its lighter, more compact design is a significant advantage for me.

Dustin, thank you for the work you do! I can safely say that these are the best reviews you can find on the Internet! :) I think the Tamron lens would be preferable for portraits. It has less defined contours, slightly lower contrast and softer bokeh. This is preferable for a portrait. In this case, he is not afraid of a drop in sharpness at the edges of the frame if he is shooting a portrait. And when shooting a landscape, everything will be corrected by closing the aperture.

Thanks @dustin - this is a great comparison. It’s a tough choice if weight matters but the sigma seems to be superior for the modest price difference.

Brilliant comparison 👌👌

Thank you for this. I think you've pushed me to the Sigma (although I continue to look at my Bank Acct to see if I can pull off the Sony…but geesh, that is hard to justify as a hobbyist!)
