Why doesnt the E-PL1 have a built in optical viewfinder?
The E-PL1 does not offer a traditional viewfinder because of its compact size. The VF-1 and VF-2 are available accessory viewfinders that attach to the hot shoe of the E-PL1. The VF-1 is an optical viewfinder, intended for use with the M.Zuiko Digital 17mm lens. The VF-2 is an electronic viewfinder that attaches via the hot shoe and accessory port.
