[QUOTE="spb_stan, post: 627495, member: 43545"] A pentaprism is larger for the same optics as a pentamirror because the light path is longer. With a different light path length and prism size, mounting the larger prism assembly would require moving its position. The prism is more light efficient, with a lower T stop value than the pentamirror. The eye-piece would also have to move and should be larger to take advantage of the brighter larger VF image. For less money you could by a used 7x00 series camera which has the brighter VF due to the prism replacing a pentamirror. It is an interesting thought experiment but hardly practical. [/QUOTE]
