Needing Help With 3 Lens Comparison

[wcsmedia]

Greetings,
I've been trying to look for either video explanations, or still photo comparisons, and other articles online regarding three unique mid-telephoto macro lenses and I'm having a difficult time doing so, so I've decided to try a forum approach. Three lenses are currently in question for me:
1) Tamron SP 28-75mm f/2.8 XR Di LD EF
2) Canon EF 24-70mm f/2.8
3) Sigma Art 24-70mm f/2.8 DG DN

I already own the Tamron and it has been a magnificent lens for well over a decade now, but I'm needing some guidance regarding the other two lens against the Tamron. I love my Tamron lens, but like everyone else who takes the quality of their photos very seriously, I'm especially curious if the Sigma is significantly better. As mentioned above, I cannot find a comparison online regarding these specific lenses and I really want to know if the extra money is worth it. Something tells me the Canon lens may not matter and the real comparison is going to come down between the quality of the Tamron and the Sigma, but I could also be very wrong in that assumption. Thoughts and feedback are greatly appreciated! Photo comparisons if you own these lenses would be even better, but whatever you can contribute would be fantastic. Thank you in advance!

Personal opinion from a non-pro! I don't think there's that much difference in the photo's they take. Mostly the difference is in cost. they difference in quality it would take a very experienced pro to tell you. Everyday people are not experienced pro's. On top of that I suspect you take the same picture with each of those lens's and have the best pro identify which photo came from what lens he'd have a hard time if he could do it at all. For most decent photo's I think the quality is no more than one persons opinion, no more and no less!

Get the lens you can afford and start from there. If you don't like it, get a different one but chances are less than a true pro will not have a problem with any of them! When a customer looks at your equipment, they notice brand names like Nikon, Canon ect, lot, maybe most have never heard of Sigma or Tamron and my decide the quality of the shot before it's even taken. If I were a pro, all my lens's would be Nikon, Canon or Leicia. I suspect those brand names might be working longer also.

Actually, since new lenses have come out since the last previous post, if someone has experience with a more recent lens, then the information will be new, and likely, different from the previous posts. Personally, I won't likely be buying such a lens in the near term, but I'm interested in hearing what has happened lately.
