Sony 18-250 vs. Tamron 18-250
Apr 7, 2008

Can someone, who had both, comment on the differences?

So far I've read/know:

Sony has circular aperture blades - Tamron is unknown.

Sony has faster gearing -> faster AF. How much faster? Also quieter? Probably less accurate?

Tamron has zoom lock - Sony probably not. Had two KM 18-200 that showed heavy zoom creep after some time, despite any affirmation from KM, the lens doesn't need a zoom lock, because it wouldn't creep. :-/
So anyone observed zoom creep an his Sony 18-250 already?

Tamron has better zoom/focus ring.

On the 18-200, the KM had much smoother manual focus than the Tamron. So how is with the 18-250?

Price gap seems to have widened between the two. Sony currently is about 560 € vs. Tamron 400 €, so it is the question, whether the Sony is really worth an additional charge of 160 €.
