I'm going to throw my two cents in and it's all from experience. Sharpness on static subjects, is not really a complete test for any type of wildlife/birding lens. How the camera reacts to fast focusing and even harsh lighting conditions/lens coating/ really tell the whole story. A lot of these lens tend to lose Detail under fast focusing conditions. If we are talking the best bang for the buck, then I'm in the wrong conversation. I'd rather pay the extra money to get the best possible finished product. I'm not trying to step on toes here, just voicing an opinion. I see many folks running out to buy either lens expecting miracles. It's how close you get, it's about the perfect light , it's about the focusing in a Split second. For slow moving large animals, these lens may be the best for the buck out there, but for BIF and fast moving prey, I don't think they can handle the job.

Yes you are correct, but they fill a niche market.
Not that the comparison wouldn't be interesting, but they should not be expected to compete with the $5000/$10,000 plus lenses.
As with any camera product there are compromises and used within their capabilities they perform admirably well.

To my untrained eye there's not a dimes worth of difference in these two. Both are reasonably sharp fully zoomed and wide open. That pole looks like the one in my back yard.

Maybe you have £8000 + to throw around or do Canon /Nikon just lend you these expensive lens, most of us lesser morsels have to be content with some what less expensive glass and we or some of us , consider ourselves fortunate to be able to capture images of wildlife and sports that a few years ago were beyond our meagre budgets and our short lens.

taken with a lens that cost less than £900

Much of the responses have got off course because some have forgot why we are here. To enjoy and be around photography for hobby/ business or both. I have been around cameras some since 6th grade when we got to develop our own black and white picture we took. I was hooked with the amazing magic. I am talking way back some 48 years. People ask questions for many reasons and those who ask because they don't know or want to learn are those who I respect. For me having a Canon camera would like to purchase a Canon lens but don't have a unlimited cash supply . The two lens's Tamaron and Sigma are one that one photographer suggested as good alternatives to the lens manufactured by the camera maker. I thank the writer of the article for sharing information that I did not have about differences of the lens and your observations and thought.

I agree to buy the best lens that will do the job and do not like settling or wasting money on something that just is average. Most of the time photo opportunities come and go quickly; that means the lens has to be quick accurate and hold the shot. I need a much longer lens than I have and looking at the zooms for versatility. Yes I am looking for information on the differences available for Canon.

I'm seeing a difference in the exposure times.
Could that make a difference? Just curious...
Other EXIF data seems to be the same in the exhibits.

But the Tamron:
Shutter Speed (Exposure Time) = 1/724.08 second

VS:

Sigma:
Shutter Speed (Exposure Time) = 1/1024 second

Lets give both Lenses a fighting chance to show their stuff.
I would go shoot the same subject on Manual settings and start with,
f/7.1 - f/9 at 450mm to 550mm which are more ideal settings for both Lenses.
For the Camera, Shutter Speed at far far less than 1/1000 sec and ISO less for a still images.
And a more modern Camera.

I downloaded both copies and used the PS CC filter Shake Reduction at 30 px , other settings at 30 too for both photos . To me , the sigma came out on top as the sharper when zoomed in a lot . Just my opinion , Tommy

Funny, not many people would call the Canon 7D MkII a "less than" modern camera! Full zoom and wide open is usually a lenses WORST image quality, that is exactly why I chose to post the original pics shot just that way. No variables, same settings, same body, no better way to do a direct comparison without investing many hours of comparable shots at varying exposures. This takes the camera AND the photographer out of the variable and compares only the lenses.

What I DO know is I was enjoying (fighting with) my Tamron while Sigma was spreading rumors.
I don't care whatchya choose, I don't care why.
I do know that for three young women, and especially their families, I saved the day from the nose bleed section of the stadium.
These girls have grown up together.
Real Life.
Their parents couldn't do this. So Grandpa Sonny got them for them. My pleasure. ;)
1st at 150mm, rest at 600mm.
