mini35's prism
Anybody try to look inside of the mini35 to see if what prism they use? It looks to me from the picture (I never seen the real one) they use 1 roof prism and 1 penta prism to correct the image, this is just my opinion. Any idea?

I think there should be 2 mirrors, 1 you cannot see facing backward. This 2 mirror do the job of penta prism. If only 1 mirror, the picture will be upside down.

Thank you for your link. I still think 1 roof prism and 2 mirrors or 1 roof prism and 1 penta prism will give the shortest path of light. They are more expensive than the 2 right angle prisms but will give a more compact design. Thank you.

No. To my calculation, using 2 right angle prisms to get 24mmx18mm, 1 should be at least 24mm thick x 26mmx37mm and 1 should be at least 18mm thick x 35mmx50mm. So to make the unit compact, I ordered the size close to those. Surplusshed doesn't have those size.
