"Exceeds my expectations from Olympus"3.5 starson by lordDevin
Pros: Many many lens options, price point both cf and xd slots
Cons: prone to noise on higher ISO, crop factor of 2 :( , image stabilization is done through the body not the lens.
Summary: Well to begin Olympus has done very good work comparing the past models to the 520. Being the inventors of the 4:3 system this has allowed for small compact cameras and also small compact lenses. However this said, the 4:3 system is prone to noise on higher ISO's In fact I would not recommend shooting above 400. Speaking of the sensor the small size, this leads to a crop factor of 2. Meaning that shooting with a 25mm lens is equalivilant to 50mm on a full frame sensor. This compared to the Canon sx with a factor of 1.6 or a Nikon D 60 with 1.5 kind of pushes me towards them.
10 Megapixels is nice on the camera not doubts on that but really the larger sensors in the canon and nikon would allow for a a less noisy picture and larger prints sizes. This said if you largest print is an 8x10 and you do not edit to much then your fine, but really why not save a couple dollars and pay a compact.
Moving on the IS system is done through the body not the lenses while this might just be personal preference I tend to prefer the IS in the lens. Its seems to be more accurate and to give a finer result.
Finally on the bad points the Olympus lens themselves are excellent yet you must remember the crop factor of 2. meaning that 7-14 mm lens is actually a 14-28mm making the price tag seem a little to much. Its also makes it nearly impossible to find a very wide angle lens. If this is your style of shooting I would send you towards Canon with their 10-22 lens or the sigma 10-20.
The good points :)
the live view is brilliant, though a bit useless for actually taking a picture this is not an Olympus problem, yet for all DSLR cameras and this is mainly due to the mirror itself it must cut the live view and take the picture and then flip back up to engage the live view , which well kind of leads to a small delay. This said you can use the LCD to to set your shot up as it shows you your picture when you change the shutter speed and f stop and such. The mirror issue though may be tackled with the G1 when it is released. Leading me to my next point. Using a simple ring you can use panasonic and other 4:3 lenses which is bloody brilliant. I urge you not to limit yourself to Olympus look around you might just be surprised. :)
over all I like this camera quite a bit and I have high hopes for Olympus in the near future. Providing you research the 4:3 system before hand I would recommend this camera to you.
