Murray,
Just about all of my pinhole work is done with the 8x10 format and the
results can be quite sharp. Not "tack sharp", but detail is definitely
achieveable. Here is my pic from the last WWPD.

The flowers and vase were a blur due to the wind, but if you look at the
grain in the barn wood you can definitely see some detail there. Hope
this proves to be helpful.
