Canon vs tamron 70-200 comparison

Lens Comparison: Tamron SP 70-200 f/2.8 Di VC USD vs Canon EF 70-200 f/2.8L (PART 1)

Tamron SP 70-200 f/2.8 Di VC USD vs Canon EF 70-200 f/2.8L

I hope that you’ll forgive me that this video is not quite as satisfying as my previous efforts. It was not for lack of trying. After taking thousands of test shots through the Canon and Tamron lenses, I discovered that the Canon 70-200 f/2.8L IS II that I was using was flawed; perhaps damaged, perhaps in need of calibration… but in any case, it was not operating as it should.

Watch Part 2 of this comparison, here.

The Lenses

The Canon 70-200 f/2.8L IS II is regarded as the sharpest and probably overall best professional zoom lens in its class. Released in 2010, it’s a relatively new design and comes with a hefty price tag. Currently at Amazon.com it costs $1999. At B&H it’s also $1999 with current rebates.

The Tamron 70-200 f/2.8 Di VC USD is an even newer design, having reached the market just last year. Tamron has long had a strong reputation for great optics at reasonable prices. Tamron’s 70-200 f/2.8 VC USD currently costs $1499 at Amazon and at B&H its $1499 plus a $100 mail-in rebate, though the price can fluctuate depending on rebates being offered. With or without rebates, the lens costs about $500-800 less than the Canon.

True Focal Length

I have heard reports that the Tamron lens does not provide a true 200mm focal length at the long end of it’s zoom range, and this can be misleading. I’ll provide a complete test in Part 2 of this video comparison.

For now, though, let me explain why this is more complicated than it sounds at first. When focused at infinity, the Tamron does provide an equivalent focal length to the Canon at about 200mm.

The phenomenon in question is referred to as “breath”, and it’s a problem that occurs when a lens loses focal length as it focuses on subjects that are closer to its minimum focal distance. So, while the Tamron is a 200mm when focused far away, it might be less than 200mm when focused close up. This is not an uncommon problem, even with high quality lenses: the Nikon 70-200 f/2.8 VR II breaths down to 140mm from 200mm when focused close.

In the video above, I intentionally avoided this problem while making my resolution tests by focusing both lenses on very distant subjects, and as you’ll see in the video (images are 100% crops) and below, the difference in focal length is negligible; the lenses focal lengths are identical for all practical purposes at that distance.

Autofocus Performance

When shooting sports in low light, I found that both lenses performed very well. The focusing motors are both fast, and tracking was equally accurate. I did find, however, that when using image stabilization, the Tamron suffered a noticeable lag between the time that the VC started to engage and the time focusing began. With a little practice, I was able to anticipate the lag and work around it without too much trouble, but it is something to be aware of.

Image Quality

In terms of resolution, I expected the Canon lens to out-perform the Tamron, just as its counterpart did (however slightly) when I compared the 24-70mm lenses. However, after comparing numerous images, I found that the Canon was consistently blurry compared to the Tamron, and in fact, it was blurry compared to my older Canon 70-200mm f/2.8L (non-IS).  Since I know that a good copy of the IS II is always a bit sharper than the non-IS, I could only conclude that I’d received a bad copy of the IS II for testing.

The images below show how dramatic the image quality differences could be. Here are some thumbnails of two images shot at 70mm at f/2.8.

In the center of the image, the difference is not especially dramatic, though it is visible.

Towards the corners, though, the Canon looks terrible.

I shoot with the Canon 80D and the Tamron 70-200 G2. Before the G2 I had the Sigma 70-200. Phenomenal improvement. Cut my editing time in 1/2. I primarily use this set up for sports, and I am rocking it! Highly recommend!!!!

Hi, for an 80D which one would you recommend and why – Tamron 70-200 f/2.8 G2 or the Canon equivalent. Read in your older replys that you suggested the Canon for APS-C instead of the G1. Why is that? And still the same with G2? Thanks

Hi Matthew,
I hope that I’m not stepping on the wrong turf with my question.
I am strictly an amateur at photography with about 35 years of experience in taking blurred images.
I recently upgraded from an old eos350 to a eos 6D and have found a new universe in how to ruin a perfectly good shot :)
I have a EF 24-70mm F/4 L Series Camera Lens that came with the frame and for a an amateur I like it for anything under 20m but anything past that goes to the blurry category.
I was impressed with your reasoning in the above comparison and thought that my original thoughts on the differences was founded.
Now the GS model being available I want to look at it and add a 2X magnifier to it for my longer distance scenery shots.
Have you any thoughts on using the magnifiers and is it a worthwhile option?
Or should I be looking at other options.
Thank you in advance for any help.

I just picked up Tamron 70-200 VC, not the G2. Did I make a mistake, I really don’t shoot any sports, what this lense does have a shorter close-focus distance. Will I eventually be sorry I didn’t get the G2.

I am about to buy a Canon 7D. I am thinking of getting the Canon 24-70mm 2.8L, is it really that good compared with a Tamron in the same range relating to sharpness?

I have upgraded my camera body about a year ago to a Canon 7D in the hopes to capture some better quality sports photos. I shoot a lot with the Tamron 70-200 2.8 but have noticed the images are just not as sharp as they should be. I mentioned this to a professional in town and he said the 7D is fussy and doesn’t play well with anything but Canon lenses. Have you experienced this?

KAT

I like Tamron’s lenses especially the older heavier model of the 70-200mm f/2.8. Is there any truth to the rumor that the Canon 70D body doesn’t work with the Tamron 70-200mm AOO9?
Thanks

Can’t wait to see the Part II! I’ve been wondering if it’s worth the difference for some time. That extra bit of cash could mean an extra prime lens!
