Sigma 28-70mm DG DN E-Mount on Sony A7III Camera Compare to Tamron 17-70 Size with Images

I just picked up the recent Sigma 28-70mm F2.8 DG DN lens for my newly purchase Sony A7III. The lens is very well built, feels very solid. it&compact and lightweight. The image quality is very sharp. Went out and took some images of Downtown. the sharpness is excellent. Colors is good. I opted for this over the Sigma 24-70mm because of the size and weight. I know going with FF, it&hard to avoid sizes. Will I&keep this small for now.
