I am new to photography and currently i hv a sony A100 (2nd hand). I walk around penasula and funan n see mostly nikon n canon lens
Currently I am holding a 18-70 sony kit lens n want to get a better one. I love the 16-80 sony cz but than if i convert to full frame next time, this lens will hv no value.
Any one hv the 24-70 sigma (non hsm) and any comment on this lens?
