I am very tempted to sell my Tokina 28-70mm f2.8 lens to get this sigma 18-50mm f2.8-4.5 with Optical Stabilisation. I am using a Nikon D200 and wants to use a lens that is perfect for all around, can you please help me decide? this tokina 28-70mm f2.8 constant is very soft wide open and doesn't have a VR, I am planning to use a lens that is good for portrait (I am wanting to shoot a wedding as well). The reason I am wanting this sigma 18-50mm f2.8-4.5 is because it has Optical Stabilisation and the aperture is better than the kit lens, now can you tell me if I am stupid ever thinking of replacing this lens with this new sigma 18-50mm OS?
I will appreciate any opinions you can provide me. I will decide based on your opinions.
