Hi, I'm Sara Grace and I need a little help. I have a Pentax Kx DSLR. First, let me say that I am NOT a camera guru, but I surely love taking photos and am learning a few things. I take my camera everywhere. Anyway, my husband and I previously owned the old Sears brand 35mm, which we understand was made my Pentax for Sears. All the lens for that camera would fit any of the Pentax cameras. So, I bought this camera not quite 2 years ago. It has recently become stuck in manual mode. (Yes, only I could manage that, I'm sure.) My camera goes everywhere with me, even to work on occasion.
I wanted a larger lens that those I have, so I found a Sigma 70-300mm and my hubby bought it for me. It has worked great until recently. Not long ago, I was trying to take pics with it and it would not snap the shot. I kept working and working with it and it would do nothing. I pulled out my book to troubleshoot, which was not use at all. Finally, I thought I'd just take the batteries out and put a new set in, although those that were in there still had plenty of juice. Well, it started working fine. Then yesterday, I'd put the large lens on to take some photos at the lake. It would not do a thing. I went back to the car and put my smaller lens on and it just snapped away. Do you think it could be the batteries or do I not have the setting correct? Help please!!
