I have been somewhat unhappy with my Canon. I struggle to get the crisp clean images I get with my other lenses. My Sigma 85 seems to a lot easier to get a crisp colorful image. My canon 100 is way better. I read that the primes are always better. Has anyone tried the Sigma zoom next to the canon?

I bought the Tamron SP 24-70 DI VC G2 and it is every bit as sharp as my Canon 24-105 II, which I love and get stellar shots with it on my 5D Mk IV. They are the same price @ B & H and I have had great results with Tamron, so that influenced my choice.

Perhaps the apples-to-apples comparison should be the Canon 24-70 f2.8L MKII vs the Sigma 24-70 f2.8 Art (or the Tamron). You may find this thorough comparison test by Lens Rentals to be useful: https://www.lensrentals.com/blog/2017/07/sigma-24-70mm-f2-8-dg-os-hsm-art-sharpness-tests/

You are trying to compare two very different lenses. Canon and Sigma both make a 24-105mm F4 lens. The Canon focuses faster but the Sigma is sharper.
In the 24-70mm F2.8 both are quite sharp, but the Sigma focuses faster and has stabilization, plus it costs much less and has 4 times the warranty of the Canon.
Choices can be tough.

Canon body = Canon lens.

That is a rather simplistic way to purchase a lens, when in fact many 3rd party lenses rival Canon's offerings at substantial savings. As for me, I'm a discerning buyer, reading reviews, field tests, cost and purchaser feedback. In my camera club there is often a member who has a lens I'm considering, and allow me to take it for a test drive and I as well have loaned my lenses to other members. (no renting) There are many other lens options out there besides Canon, and I always try to get the most bang for my buck considering IQ, focusing and build quality and don't make brand loyalty my only criteria in purchasing a lens.

Please clarify the above. I read that you loved the Canon 24-105 and then bought the Tamron 24-70 G2 "which is every bit as sharp". In your opinion what was gained from that purchase? I ask because I'm re-evaluating my lens lineup. Thank you.

I use my 24-105L II on my crop sensor 80D & My Tamron 24-70 G2 on my 5D Mk IV. I just like the extra reach when on the 80D and eliminates me having to change lenses on the fly. When I go out looking for something to shoot I always take both cameras and it's just more convenient for me, and IMO the IQ from either set up is indistinguishable. Both are superb. These were taken hand held from about 8' away with the Tamron 24-70 G2 on my old Mk II which I traded to Adorama when I purchased my Mk IV.

Makes sense to me.

I have talked to various people about the 24-70 vs the 24-105, almost everyone of them wished they had bought the 24-105mm instead. For one simple reason, it has a longer reach.

I have struggled with that also. If you beleive DXOMark testing, the 24-105 f4L IS is about as sharp as the 24-70 f2.8L and not as sharp as the 24-70 f2.8L MKII. The question being would you give up the extra “reach” of the 24-105 and the IS to get the extra stop of the 24-70 f2.8, which is one of the “holy trinity” of Canon zooms? So far, I haven’t been willing to give up my 24-105L, but I revisit the question regularly.

I am not opposed to buying used lenses. In my area, Denver, 24-105's can be found for under $600. I paid $400 for mine.

I have bought used lenses from Craigs List, Amazon and ebay without a problem. Look in your area for a used lens. You might get very lucky
