Pentamirror Vs Pentaprism. Pentaprism In reply to jojomogir Apr 10 2004 The D100 does have a viewfinder with higher magnification and it is one of the few areas that the D100 is still better than the D70. Generally some of the advantages of the Canon 10D compared to other pro DSLR competitors include. It is used to reverse again the laterally reversed image coming from the reflex mirror.

The Pentaprism is the device that is used in the viewfinder of DSLR cameras. My camera has a pentaprism and is rated at 095x magnification and a nearly identical model with the pentamirror has 085x magnification. Im really tempted by the D70 just had a birthday and want to just get it and I guess I could always trade up when the next model comes out. I know what exactly those things are doing but what is the. The basic difference is that a pentaprism is a solid block of glass. A pentamirror is an optical device used in the viewfinder systems of various single-lens reflex cameras instead of the pentaprism.
This means its fairly heavy.
As the pentaprism is made entirely out of glass it is heavier than pentamirror. 2132013 As you can see in the video above pentaprisms are made from high quality glass and pentamirrors are hollow constructions with some of the walls having reflective surfaces. It uses the internal reflection properties of glass that direct light from the lens thru the eyepiece. 4152010 Pentaprism viewfinders typically have a larger andor brighter image than pentamirrors. As the pentaprism is made entirely out of glass it is heavier than pentamirror. Guess the difference would be a pentaprism the light passes thru the glass.
