Very good condition. Shutter works properly at 1/60 and shorter (at 1/30 and B curtains move lazy)  Self-timer does works properly. Body has signs of use and age. Pentaprism in the viewfinder is inclined a bit to the right and has microdust. Lock of rear cover opens tightly. Lens is not included, body only.
