This might be a silly question, but Googling around, some sources say its 62mm, while others say its 72mm. Can anyone please shed some light on this please? Thanks :)

Hmm, interesting that Tamron lists it as 62mm and B&H as 72mm.

Based on the aperture and focal lengths, would suspect 62mm. However, doing an image search, I noticed one with a protective filter apparently labelled 62mm, and another with a box clearly labelled 72mm. Looking further, I noticed this info from SLRGear:

"We tested the original Tamron superzoom in early 2009, citing its handiness and compact size as the main advantages. In the late-2010 refresh of the lens, Tamron has developed a new focusing technology, bringing it in line with other manufacturers, using ultrasonic ring motors instead of conventional mechanical motors to drive the focusing element. Additional changes include the use of rounded diaphragm blades, the use of 62mm instead of 72mm filters, and an overall reduction in size and weight. The 18-270mm is a Di lens, meaning it was designed for the reduced size of a subframe (APS-C) digital sensor."

So if you have a post-2010 version, it is 62mm.
