Wow, I am really enjoying reading through these forums! Looks like Tamron and Sigma have both released very similar lenses, perfect for digital.
There's the Sigma 18-200 and also a Tamron 18-200. All specs are almost identical - weight, size, MFD (what's MFD???). Macro magnification ratio is slightly different - Tamron = 1:3.7 Sigma = 1:4.4. Which is better? The bigger number is better?
Sigma looks way better in my opinion, ha ha.
