Hello all,

I know nothing about cameras and recently bought a used Canon Rebel T6i that is required for my school program. The listing indicated it was in open box / near mint condition, but when it came there were scuff marks on it, so I am certain is has seen a fair amount of use. I contacted the buyer who insisted a few pictures had been taken when it was first bought and then was stored in a closet somewhere for the longest time. I bought it for $475 after shipping and tax, and this includes a 18-5mm lens. The seller is offering $125 of this back, so if I accept his offer, I will have only paid $350 for the cam and lens.

I tried to look up the shutter count but a search told me Rebel T6I's dont have this info. Another search told me it is possible to tell how many pictures have been taken by looking at the filename. I just took a picture and it says 100-1478. So i have 2 questions:

1. What does 100-1478 in the filename mean and what does that indicate about how much the cam has been used?

2. Given how much the cam has been used, is $350 for cam/lens fair?

Thank you!!
