Im undecided whether to get the sigma 18-35 or the tamron 28-75 2.8 for my new a7iii. Will be using this lens for short films mostly. The 28-75 kit lens is actually pretty good, but would not mind a constant aperature and more light.
Pros for the sigma are lower f stop and i could use it on my gx85 and sl2 cams. Pro for the tamron i guess is full frame video if thats much of an advantage.
Also, anyone try the sigma 17-50 2.8 with an A series camera?
Any input appreciated, thanks!
