Sigma 17-70 OS HSM ISO Question
Based mostly on reviews in the Pentax Lens Forum, I recently purchased this lens for my K-x (1.01).
I took it out for a brief trial run yesterday and liked it quite a bit. One thing I noticed that confused me is that no matter what capture mode I selected, I could not set an ISO below 400. All of my Pentax kit lens and a DA 55-300 allow an ISO setting of 200.
I could not find any info on the literature that came with the lens nor in the K-x manual.
Is this a "feature" of this lens?
I also noticed that neither iPhoto nor Aperture recognized the lens in the EXIF data. Again, is normal or did I miss a setting?
Thanks,
