Hi Folks,
I'm wondering if anyone can help me by recommending a telephoto lens that would be compatible with a Pentax ist DS.
I have looked online as to what lens mount I have but I am finding it confusing working through compatibility issues.
I'm after say around a 50 - 500 lens.. or 150 - 500. I thought the Sigma ones would do the trick but have found that you lose functionality (auto focus etc)
I'm only a bit of a beginner, but had a few lenses for an MZ 50 that worked for me and picked up the ist DS a few years ago and found they were compatible. Am now just dabbling with wildlife photography and would like a super tele.
Any help REALLy appreciated!
