Try as I might I cannot find a way of knowing what my shutter count is. I have a Canon XS and a 3 Ti and in spite of posts telling me how, none seem to work for me.
I ask this as I am suddenly seeing much more debris arriving on my sensor with the XS even in a closed OTA train.
The arriving "rocks" are more than just dust motes.
Is there a typical way in which the mirror/shutter mechanisms fail? Am I seeing a deterioration in any "soft" components, e.g. flaking rubber/non-metal part/trims?
