nice picture, what aperture is that? at 100mm f3.5 i dont know how you can have a subjet in focus with a manual lens (that's why i gave up my 50mm, couldnt get anything in focus open wide)

Guessing it's not af right?

that's what i told him, to put my name on it if he uses it. thanks for your help!

thanks

thanks guys. This looks pretty expensive. I am actually not charging (trying to help their business), but thought maybe I should protect myself..? although it doesnt matter that much I guess - I guess there is no risk of them making money out of the shot or am I missing something?

hello, someone (a hair salon) would like to use one of my shots - I am very happy for them to use my work, but wondering about copyright - does it matter? what can happen? what's the point to register?

should i just not bother? not sure exactly what it'll be used for, apparently for a "book", maybe a website -

thanks!

since you have both the 17-70 and 18-135mm how do they compare?

everyone has the non OS version though... i like the OS one also for the hsm, and the third stop at 70mm... although 1/3 stop is not that much actually - let me reconsider my comment! now cant remember why else i wanted the OS version, well i guess if it is better than the SR then it might make sense as could shoot at f4 with less light.

still not convinced by the sigma but i do want something longer than 50mm!

4 stops seems crazy! i know that's what sigma claims but i am sceptical here!
thanks though it's good to know -

Hello,

I own a tammy 17-50mm f2.8 which I am very happy with in terms of quality. I however realised this wkd that 50mm is too short for me! Although I own a 18-250mm which I find really good when travelling, I dont think we can compare the quality of the two. Therefore it leaves me unsatisfied (!). I was tempted to try the 28-75mm ultimate wedding lens, but think I would miss the 17-28mm range too much.


I havent seen that many reviews of the 17-70mm OS version, it seems the OS is not any better than the Pentax body IS, is it true?

How does it compare to the pentax version? is it overall better or similar? the pentax seems to be weak on the focusing from 50mm onwards - so not very appealing. However the pentax has 67mm filter size so I could use my filters (vs 72mm for sigma).

Then comes the pentax 18-135 which sounds like my dream lens, but much more expensive for now, would need to be in the £300ish range.. or should i just wait a few months? and/or buy it second hand?

thanks
