Hi, I am interested in the filter you are selling. A quick question tho, is it this one ( http://www.amazon.co.uk/Single-Coated-Neutral-Density-Filter/dp/B00485XSQ6 )If so would you take a little less for it as it is £70 band new. I can offer £50.

Hi guys, after having my kx for a year now i think its time to upgrade my kit lens. So I was thinking of getting a tamron 17-50 2.8 after reading good things about it. The problem is tho is should i spend £300 on the Tamron when I can get a used 16-45 and a flashgun for around the same price? or even a 16-45 and a nice prime? Is the tammy a lot better then the pentax? Or is there another lens I may have missed? Any ideas peeps?
