Thanks, must admit I never considered this, reviews didn't seem to get close to the Sigma and Pentax, but then reviews.....

Delighted with my K-30 and the 18-135WR. Got a prime SMC M 50 from ebay and amazed at that.

There's an offer on for the Sigma at £169 with the Pentax at £258. I need one or the other for a little fun on the coast with fishing boats/people at distance/surfers as well as a little general fun at home. I'm thinking I'll use at the long end quite a bit.

Having read reviews and other forum comments I understand that the Pentax choice is the accepted wisdom as the best choice below say £300.


However there are a number of comments that the OS version on the Sigma is better at the long range than internal stabilisation. There is also quite a price difference which I would appreciate but if there really was a substantial difference between the IQ I'd go for the Pentax.

I'm also thinking that when I go walkabout will I miss the 15mm shorter on the Pentax.

Decisions, decisions.........

Please would members share their views on my best choice. Cheers to all.
