Although it is pretty bright - (the penta mirror is an improvement on the L1's porro finder) - the L10's viewfinder suffers from the same 'looking down a tunnel' effect as all Four-Thirds SLRs, making it difficult to accurately gauge focus - the image is simply too small. In recognition of this 'issue' Panasonic is supplying a 1.2x eyepiece magnifier with the L10, which produces an image as big and bright as any APS-C SLR, but comes at a price; the eye point is reduced so far that you basically have to press your eyeball up to the glass to see the entire frame (more specifically, to see the viewfinder information to the right of the frame). Using the magnified eyepiece with spectacles is tricky, to put it mildly (fortunately there is a dioptre adjustment).
