Thanks for all of the detailed replies!
Upon more research (and reading tons of reviews), I think I have my choices narrowed down to two lenses:
*Tamron 17mm-50mm f/2.8 lens
*Tamron 28mm-75mm f/2.8 lens
I have read great reviews on both and seen beautiful video for both. Plus the wide aperture is a bonus for low-light shooting, etc.
However, would one consider the 17mm-50mm redundant, since I already have the 18-55 kit lens? Or could it be considered a sufficient upgrade/replacement?
Regarding the Tamron 28-75, although it’s not as wide angled as I would like, but it would give me additional zoom capabilities.
Thoughts???
