I have had the camera for two years now and am very happy with the pictures it takes both outside and indoors. There are various shooting modes for different situations and after having played around with the settings for a while I am now able to choose the most appropriate one, however this did take quite a bit of investigating. I think that the menus on the camera can be difficult to navigate which isn't great when you're trying to take a quite snap. I really like the look of the camera and I think it feels heavy and robust. I did have an issue with the lens shutter breaking but Olympus repaired this under warranty and returned it to me quickly and I haven't had any issues since. The only other downside with any Olympus camera is the use of XD rather than SD cards which means that the storage I already have can't be used with this camera.
I have had the Oylmpus MJU 750 for over a year now so hopefully my opinion will help you if you trying to decide weather to buy one or not.
First the good points.
This camera is a really good size if you want to carry it around in your pocket or put it in a small bag. I have a 512 MB XD memory card which holds over 300 good quality pictures.
I bought an extra lithium battery so I don't have to panic when the battery life starts to flash, but the battery life is pretty good - if it is full it will easily last over a day taking lotsof photos, eg at a wedding.
Outdoor the photo quality is great and the colours are really bright and sharp.
When downloading the photos or printing directly the Olympus is really easy to use.
Now for the not so good points.
My main compliant with this camera is that it seems to be really difficult to take a good picture indoors, I have tried various settings, but it's either over exposed / too dark / blured / or slightly out of focus.
Now I know my photography skills might not be what they should be, but I just wanted a fairly good camera to take nice photos without too much hassle.
One other thing to mention is that there is no viewfinder on this camera. This might not seem a big deal but when it is bright outside it is really difficult to see the screen - I've compared it to other similar cameras and mine is by far the most difficult to see!
I hope I haven't put you off too much, if you get a good deal the camera is ok, but if you are serious about getting good photos most of the time - you might be better looking elsewhere!
