Originally posted by Skodadriver I have one though I have not used it for years and not for portraits. The reason is that I was not happy with the colours it provided, they seemed a bit pale in comparison to other lenses. Might just be my copy though I also have a Sigma 24-70mm of a similar era and find the colours about the same. Not as sharp as the Pentax-F 35-70mm either.
No reason not to use it of course, it would be your opinion that would count most.
If I was to want a portrait zoom, I think having a good wide F2.8 short to 3.5 long aperture lens would be the way to go.
Thanks for your response and I agree with what you said.
I do have other lenses in my bag but I though I take it out in probably the worst possible conditions, cold +3 deg. C, overcast sky and using strictly Program Mode on the camera just to see what developed
