This finder proves its worth when you wish to use the camera at a low angle or view the subject at a right angle. This can include fields as diverse as photomacrography and astrophotography. The retractable barrel makes the finder even more compact. A builtin flip-up magnifier enlarges the image 4.6x for increased precision in focusing and composition. All exposure data are displayed unreversed and an adjustable rubber eye-piece hood blocks out stray iight. Because of its light weight (approximately 1/3 that of the FN-6X), it is an ideal accessory for the naturalist who wants to photograph plants and insects on field trips.
