Hi,
I have a Nikon d3200 with a 18-55mm kit lens. I want a better and wider aperture lens with zoom. I was thinking of buying the sigma 17-50mm f2.8 but I also found out about the sigma 17-70mm f2.8-4. I generally shoot indoors, flowers, portraits, group photos etc... Will the 17-70mm give the same results as the other with more zoom or is the 20mm extra zoom very insignificant.
Ps- pls don't refer me prime lenses as i want a affordable zoom which is faster than the kit lens.
Thanks for your help..
