Originally posted by gnaztee If it's bigger, I'll stick with the 50-200, but if it's the same size as the 50-200 (as it looks in the K20 brochure) I'll get one, as it is then smaller than the Tamron/Sigma 70-300s. That's why it matters. Plus, I find it peculiar that they would have two different sizes floating around.

Straight from pentaximaging.com:
50-200
Weight: 9.2 oz.
Size Max Diameter Length: 2.6" x 3.1"
55-300:
Weight (w/o Hood): 15.5 oz. (440g)
Maximum Diameter x Minimum Length: 2.8 x 4.4" (71.0 x 111.5mm)
It looks like the size of the 55-300 is closer to that of the 18-250.
HTH,
