Just a thought..............................

..... does the view-finder look yellowish without a lens on it?

Pentax made a few lenses with their "nuclear range" which were radioactive .........after time the glass becomes yellow........

.........this yellow tint is fairly easily removed by putting the lens in the sun...........UV rays bleach the elements!

Oh I didn't see the previous post.......(still at least we are agreed)
