No problems yet, my only complaint is it has too many features. I've been researching a super long range zoom compact camera for more than a year, and this one is it. I almost bought an earlier version last year but it didn't have aperature and shutter priority (good for taking pictures of moving water and scenery). This one does, and it's now up to 14x. I beats the compettion for features, size and weight.
Not having a view finder isn't that bad, the bigger screen is a benefit so I don't think I'll miss it. If you want one you are talking about a different class of camera (bigger). This one is for my pack, so small and light is a priority.
Be sure to read the manual on the CD, the pocket guide is worthless. I also bought a bigger aftermarket battery but have yet to see if it lasts longer. It weighs the same as the stock one.
