Hi,

I recently bought a 45mm f4 for my Pentax 67, unfortunately without the hood.
Since the filter-thread is slightly banged I am thinking about 3D-printing a replacement hood to fit onto the outer tube of the lens.


Has somebody the ordiginal hood and could measure and post its dimensions?

Thanks for your support,
Chris

The 45mm f4 uses a spring-loaded attachment to the internal filter edge.
Dimension from one side of the spring clip recess (looking at the rear of the hood) to the next is 90mm.
This lens uses an 82mm filter; low profile B+W C-POL filters will not allow the clip on filter to be used (no internal filter lip to grip).
I don't have a vernier caliper unfortunately to make a super-accurate measurement; I used an accurate engineer's ruler.
