Is the red ring on the lenses really worth paying for?
sigma 35 1.4 vs canon 35 1.4L
Tamron 24-70 2.8 VC vs Canon 24-70 2.8 I
Sometimes I get this fuzzy feeling in my head when i carry a 5dII with a 70-200 2.8 II or even a 24-105...
But... is it worth paying the price especially for my second option?
