Hey folks! Forum newbie here. I'm selling off some of my camera collection and when testing my F/N50 (w/o film), I noticed that no matter what aperture I set in manual mode the camera seems to apply near to maximum aperture for half a second after the shutter closes again after an exposure. I've tried with two different AF-D lenses and one AF-S and it's the same there. I'm not at all familiar with this era of Nikon SLRs and can't think of any logical reason why this would happen so I need to know if this is as it should be and if I can sell it with confidence it isn't broken. Any and all help is appreciated! PS. I'm not a native English speaker so if I'm not making sense just ask and I'll try to explain.
