You can now pre-order the brand new Tamron 18-300mm f/3.5-6.3 at BHphoto here, Adorama here and soon at AmazonUS here.
Strange feelings come up. I mean, I am totally in love with my Fujinon XF18-135mm f/3.5-5.6, but I am also tempted by the new Tamron 18-300mm f/3.5-6.3. Is it allowed to have love affairs with multiple lenses? If so let me know guys, and I might yield to my temptation ;).
