Some pictures:
A5000 and the pinhole.
Sample picture of the pinhole. No vignetting, the typical softness of pinholes
in this format. No need fot full resolution, you can guess what you
get.
This is a cheap plastic pinhole device.
You can buy an E-mount version of it. There is no aperture setting and
no focussing. The plastic mount wobbles, but is light tight. The
results are very soft, which seems to be typical for 24x36mm format
pinholes.
