Hi Amita Glad to hear you got the Sigma, I didn't know that they had a Pentax version. Would you do me a favor and let me know how you like it and what the guide number is at a lens setting that will cover a 35mm lens. I know it's like 160 for something like a 105 lens. The only problem with the wedding I shot a couple weeks ago was trying to use a cold shoe flash on the Z-1p with an adapter. I finally gave up and switched to my K-1000. Are you shooting the wedding digitally or with film. I found that with the small wedding in a small function room I shot 90%+ with my k35/3.5 at F11 set on hyperfocal distance.
