Hi everyone,

I own the 4K camera with the Sigma 18 - 35 f/1.8 Art lens and recently bought the 6K Pro. I will be using both cameras at once so I obviously will need a second lens as well. Since I have the above lens already I was going back and forth between these two Sigma Art lens. It would be nice to have a zoom lens but I am torn on which one to get.

24 - 70mm f/2.8 - https://www.bhphotovideo.com/c/product/1321309-REG/sigma_24_70mm_f_2_8_dg_os.html

24 - 105mm f/4 - https://www.bhphotovideo.com/c/product/1009621-REG/sigma_635_101_24_105mm_f4_dg_os.html/qa

The 24 - 105mm obviously has more variety with focal length and is less expensive, but the 24 - 70mm f/2.8 would be nicer to have in low light situations (like the 18 - 35mm).

I haven't used either before so I wasn't sure if one was much sharper than the other and if one would be a better match with a second camera using the Sigma 18 - 35mm (I have a few interview coming up).

Thank you.
