the four thirds system

[sbaros]

It all depends on what kind of photography you plan doing and how each system can grow with your needs. Do you like wide angle photography? then canon may not be your choice because they have no realistic choices beyond 25mm (35mm equiv.).If you need or want IS/VR lenses than either nikon or canon. olympus might not have alot of megapixels (5) but it is not everything.Image processing has alot more to do with it. Olympus has commited to releasing new lenses for their system and they so far have lived up to their commitment.They seem to have the best performance/speed /size ratio out of all the companies.As far as image quality goes noise was a problem in the first samples but it seems that up to iso 800 the images look good.As far as the size of the image sensor can you afford a full frame camera? Can you wait a few years for the prices to come down?Can your photography wait for the wide angle limitations to change?Is the sigma 12-24 a good enough choice? do you even care about wide angle photography? If you need more opinions, see the dpreview.com /olympus slr forum they consistanty post images and give their opinions about the camera.It is good get opinions from people who have actually used the camera instead of listening to people that have their own agenda. Some web reviews have not given this camera a great review because of the price (which has come down from$1999to$1499) and they were comparing it to the nikon d2 or canon 1d all more expensive now. But most magazine reviews are real good.Myself I am still looking and haven't decided which one yet, even though I have canon eos film equiptment.I know one thing I like my 20mm 2.8 and my 24mm2.8 and use those alot, your needs may be different. DO RESEARCH, HANDLE THE DIFFEENT CHOICES AND MAKE YOUR OWN CHOICE
