Tamron SP 70-200mm F/2.8 Di VC USD: Digital Photography Review
This new lens looks really good, weather resistant, circular diaphragm...
Problem is... will it be released for Pentax mount? And when?
I do not think it is exactly about creating market share... but to increase exposure of Pentax products themselves IMO...
which will in turn drive up sales for other products...
my opinion of why sg is not a good model is different
sg is trade based... it has the edge of being a trade and transshipment hub
i dun think it will work as welll in developing countries
anyway people in EDMW likes to take these to criticize the government... sometimes even crappier...
