We look forward to seeing you in the shop soon. Stay well! Edit: Hi Evan, I am unable to reply to your reply directly, so I'll include the answer to your question here. The answer is maybe - if there is dust on the mirror or rear of the eye-piece. Otherwise it may need to be sent in for disassembly and further service.
Followup question: Do you clean viewfinders on digital SLR's?
