We’re on the hunt for the best zoom lens for the Sony Alpha Cameras. Especially our favorite camera, the Sony A7 III. The two lenses we decided to test are the Canon 24-70mm 2.8 and the Tamron 28-75mm F2.8. We enjoyed using both of these lenses. Keep reading to see the head to head comparison.
SIZE & WEIGHT
The Canon 24-70mm 2.8 is heavier and bulkier compared to the Tamron 28-75mm F2.8. The build quality is sturdier and it feels more professional. It’s about 805 grams, compared to the Tamron which weighs in at 510 grams. The Tamron is more plastic feeling, I wouldn’t say it’s cheap though. But it’s definitely lesser build quality than the Sony. Both lenses look professional. I actually prefer the looks of the Tamron over the Canon.

AUTOFOCUS
The Canon lens on the Canon 1DX handles autofocus better than the Tamron 28-75mm. In photography modes, you won’t have any problems with either lens’ focusing. But, if you plan on shooting fast motion or sports photography, go with the Canon 24-70mm. It handles burst modes better.
IMAGE QUALITY
Both lenses have stellar image quality. At F2.8 they are both sharp lenses. The Tamron 28-75mm is a tad bit sharper but it’s actually hard to tell. As both lenses have great contrast and sharp optics. I will say, the Tamron does vignette more than the Canon. Keep that in mind.

BOKEH
Excited to have an affordable zoom lens for the Sony A7III. Until now our options were either shoot F/4 lenses or adapt Canon or 3rd party lenses to the Sony cameras. The Tamron is F2.8 which creates awesome bokeh. I’m excited about not having to spend that extra money on adapters or buying the expensive G Master Sony lenses. But the Canon and the Tamron bokeh is comparable and beautiful. The bokeh is delicious.
My favorite lens out of these two is the Tamron. It’s affordable, gives good quality and it’s lightweight. When you’re traveling those are the best points you can have in a lens.
