I am using Nikon DX body and looking to buy a fast zoom lens, comparing between Tamron 17-50 f2.8 and Sigma 17-50 f2.8 OS. Price difference around $400.
So my question is:
If I often shoot at 1/40, do i need stabiliser?
At 50mm, what is the recommended shutter speed for handheld shot without stabiliser?
