5.0 out of 5 stars A CRACKER!, 28 Aug 2011
Having just retired from my job in medical physics with a huge NHS pension (believe it if you like) I decided to replace my old Nikon, Olympus and many other film cameras with a couple of digitals, I already have a Fuji S5000 but yearned a DSLR. I have read as many reviews as you can shake a stick at but having spent most of my life in physics have little need of technical opinions unless they are factual, most are not.
After due consideration I opted for the Olympus E510 and the Canon EOS 500 (for its movie function).
Most of the reviews I read have proved to be incorrect or misleading. Some said that the 4/3 system used by olympus was in some way cause for distortion. They (Olympus) simply use a lens which throws the image at a sensor which is SMALLER than the image produced, (by 1/3 believe it or not). Images from lenses get all sorts of distortion towards the edges,so olympus discard this part of the image...not hard is it. They COULD use all the image and a larger sensor, 15Mp instead of 10Mp but if its distorted, why bother?. Also, most cameras have noise reduction software, the sensor is NOT linear in its sensitivity to light, noise will appear in low light conditions with long exposures whatever you do (like increase ISO) this is a technology limitation of the sensor from which all camera manufacturers suffer!. Noise reduction software can smooth out this noise but you'r just replacing one form of distortion with another. The IMPORTANT thing is, like Corrie, you can TURN it OFF!
The image stabilisation on the Olympus is obtained by mounting the sensor on pizo-electric crystals which flex when a current is applied. the Canon uses a similar system in the lens. This function is available on ALL lenses fitted to the Olumpus but only on lenses fitted with IS on the Canon (with a corresponding increase in price) so in my mind, the Olympus system is better.
Both of these cameras give good results, one may be better than the other in some circumstances but in general there is little to choose, however, to get comparative image quality from the Canon you have to pay a heck of a lot of money for your lens, some of the cheaper Canon lenses give abysmal results so look at the reviews BEFORE you part with your cash.
