Summary: The zoom stopped working the second day out of the package. Then, it just started working again without changing any settings. Of course, because it was new, I handled it gingerly so there was no reason for this issue. This camera doesn't seem rugged at all, however, I'm sure this is a defective item. However, I won't chance buying this camera again.
Summary: Excellent little all purpose camera. Great macro abilities (love the little led macro lights and it focuses in macro mode in all focal lengths). Low noise even at 1600 ISO. Great image stabilization (probably 4 stops or more). And its tough, which is the main reason why I bought it.
Summary: My copy was not waterproof. I followed the instructions and made sure that the battery opening was clear of debris. During my first 10 minutes in the ocean, water got inside and fogged up in the lens. It also shorted out the Macro LEDs--some did not work, others flickered on and off regardless of the cameras power state. So glad I purchased it from Amazon instead of somewhere else. The return was super easy as always.
Excerpt: This camera flooded less than three weeks after I bought it. Ricoh acknowledged it was defective and sent me a new one. After a few days this one stopped functioning, and now won't even turn on. B&H refused to give me a refund, and I'm waiting to hear if Ricoh will give my money back. I do not want another replacement; I could never trust this camera on a trip and certainly would never recommend that anyone purchase it.
Summary: I'm a field biologist working particularly in the intertidal region of the seashore. This camera is perfect for such an environment; very sturdy and waterproof so photos can be taken within tidepools. I also had a very positive experience when the camera leaked when I was snorkeling. It was immediately replaced, and I am very pleased to have the new one.
