A good tradesman never blames his tools
And as was stated, a good tradesman does not equip himself with poor tools that are far below the specifications or inherent capabilities of his era.
The problem with d-slrs is that they are the "film" and the camera, all in one. On the camera front, the tiny viewfinders that the lower-level, older Olympus cameras have is a really big problem. A good example is the Nikon D50--it had a very small, tiny, quite simply "bad" viewfinder image...the Nikon D90 by comparison blows the D50's viewfinder out of the water. The EOS 5D's viewfinder image is massive compared to a lower-level, three year old Olympus's viewfinder system. I hate to seem to be bashing on Olympus, but some of their cameras have had quite simply, atrocious viewfinder systems compared with Canon,Nikon,or Pentax APS-C or FF cameras. Many people find that the better the viewfinder, the better they can SEE to compose and to manually focus if needed.
