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.
