This is my new camera, it's a Samsung TL500. To be honest I haven't yet taken it out of the auto mode on my last few rides but I do plan to start taking my photography a little more seriously. The very first ride with this camera I realized that the lens cap was going to be a problem. I tend to take lots of photos while I'm actually riding which makes removing and replacing the lens cap difficult.
This was my solution to the lens cap problem. I bought it from some Chinese company on Ebay. So far I'm happy with it.
The cap pops open when I power up the camera. I also bought the wrist strap so that I don't drop the camera while riding. I'd hate to see my camera skipping across the asphalt.
