I concur -- my 35mm pinhole experiments were far less sharp. This with a homemade 35mm pinhole camera:

1/2", Superia 800

Also not as sharp, but this was taken handheld (no tripod or support). Same camera:

~1/4", Fujifilm 200

I won't share my digital pinhole images, but they're less impressive, and I don't even bother anymore.

ETA: Nice locomotive, by the way, DW. I like the detail you got in the shadows. And, yeah, pretty sharp too.
