Canon vs. Sigma vs. Tamron – Lens Comparison


About 2 months ago JJ @ posted a video stating he was going to put together a test between the Canon 24-70mm F/2.8, Sigma 24-70mm F/2.8, and the Tamron 28-75mm F/2.8 in Video use. Looks like he's posted a few first samples just yesterday and in some cases you do see difference in Contrast, color, and sharpness. I personally like the Canon 24-70mm F/2.8, but if you're happy with the results, you can save a bit of money on the other non Canon brands. Here's the break down on lenses, prices, and what you're comparing.

First up Canon 24-70mm F/2.8 Wide Telephoto priced at approx $1349.00

To follow up on his first review against these lenses, i've owned them all at one point. I still have the Canon 24-70mm F/2.8. Sigma makes some really great lenses, I still rock my Sigma 20mm all the time. I started with the Sigma 24-70mm F/2.8 before my Canon L, using it for photography. Compared to the Canon it was slower on auto focus, more noise when focusing, and problems with communication when using Infrared metering from my Speedlite. This is when I upgraded to the Canon 24-70mm F/2.8 L. The Sigma 24-70mm F/2.8 of course is half the price of the Canon 24-70mm, so if you're looking for a strictly Video lens with this range, all these quirks might not be a problem for you. If you're a hybrid shooter of both Photo and Video, you'll get better performance and image quality from the Canon.

I'm not going to get deep into the Tamron lens, I love Tamron lenses like my 18-270mm as my travel lens choice, but if you're going to be dealing with the weather, this is where the Canon 24-70mm L lens proves it's worth. Many of the cheaper lenses provide decent image quality at an affordable price, but lack the weather sealing, quiet motor, and fast autofocus. I had problems with an earlier lens (I won't mention any brands) shooting in light fog which crept into my lens and pretty much ruined it with moisture from the inside. Again, if you're just doing strictly video and not worried about auto focus noise & weather, you'll find great deals in the Sigma and Tamron brands, and also Tokina which isn't part of this test because they don't have a lens available in this range.

Update: Just confirmed with JJ that his test was using the older Sigma 24-70mm F/2.8. There is another more silent and higher end 24-70mm F/2.8 HSM priced at about $899.00 from Sigma that has not been tested. This is said to be a close rival to the Canon 24-70mm F/2.8.

    Any feedback on the Sigma 18-250 mm with wide angle,telephoto and macro.
    I am anxious about focus time

    After watching this review, the Sigma is looking really good for the price. Since this one doesn't have a stabilization motor, would you think that it would be too shaky for video use when its zoomed in? A lot of my shooting is a run and gun style so I would be using this with a shoulder stabilizer.

    New to the whole DSLR game, and find your blogs very very helpful.
    The Sigma 24-70 that he tested, was it a macro or the HSM? I noticed a pretty significant price difference between those 2 Sigmas. If you have time, would appreciate it if you can explain the difference between the two also.

    Touche', I just asked JJ which version he was testing with. I'll update with that information.

  5. Mhh.. you forgot the "new" hsm version of 24-70mm from sigma.. that's (in a lot of reviews around the web) slighty better than the canon.. I own the lens and I'm really good with it (and it costed my only 600 euros - second hand)
