Was looking at some DSLRs...
The olympus e410 SLR has 95% FOV and 0.95x mag and the Sony a200 has 95% and 0.86x mag on paper but the latter is quite obviously bigger (side by side comparison).
so my question is -- the 0.86x value is a multiplier of the subject or the sensor?

Re: Viewfinder specs...
The SLR viewfinder forms a simple telescope. The magnification of a telescope is determined by both the objective lens and the eyepiece.
