look at your camera/ the eye piece is not in the same plane as the taking lens. in order for the image to get to the eye piece it must be sent around corners or bent. clearly its not hard to understand the concept if your looking in one place and the lens is taking light in in another place in most cases one above the other to see in the eye piece what the lens and sensor see the light path must be bent either with prisms mirrors or now days electronically or with fiber optics.

Must you continue to embarrass yourself with your exhibitions of technological ignorance? LOL. As everyone who understands digital technology understands, light that strikes the sensor does not travel beyond that point. The light is not bent, either with prisms or mirrors, or "electronically" (which is, apparently, some pseudoscience you've pulled out of your butt). It is not transmitted via fiber optics. It's not traveling through microscopic tunnels inside the camera body. It does not bouncing around through a series of tiny reflecting mirrors. The light simply ceases to exist beyond the point at which it strikes the image sensor. What exists beyond that point is pure digital data. There is no longer a single photon of light (which is what light is comprised of) that exists beyond the point at which it falls upon the image sensor.

The photons of light strike a light-sensitive diode on the sensor. The diode becomes charged, producing a charge proportional to the number of photons that struck it. This charge is converted to a signal. This signal is converted to a digit, or series of digits. These digits encode color information and light intensity, as well as the position of this color and light intensity. In other words, this digital data is most definitely NOT light, just as the typed words on the pages of a book are most definitely NOT sound. And just as you might transport a book across town, you're certainly not transmitting the sound of those words across town. The same goes for the digital data traveling through a camera. It's not light that is traveling through the camera, merely the digital data that resulted from the light striking the photo diodes of the sensor.

Honestly, the level of ignorance and non-sense you're exhibiting on this subject is almost unbelievable, I have to wonder if you're pulling my leg?! Are you? You honestly believe that it is light that is existing, persisting, and going beyond the point at which it meets the image sensor? You honestly believe that "the light path must be bent either with prisms mirrors or now days electronically or with fiber optics" in a mirrorless digital camera? Surely, this must be a joke. Obviously, no one can be so foolish. Pal, you got me, you got me good. LOL.

well yes it is it has to be moved from the senor to the eye piece. but clearly we are only disagreeing on semantics of the definition of reflex in the photographic sense. You maintain the word only applies to optically bent light path and I maintain the meaning valid for electronically bent light.  Light goes in the lens you see the image in the viewfinder. however it gets there is not the issue. the issue is the light path has been interrupted either by a mirror or prism or fiber optics or electronically to reach your eyepiece which is not directly behind the taking lens. But even in an evf camera the image you see in the eyepiece has been optically bent as more often than not the lcd is horizontal and the viewfinder still needs a mirror or pentiprism. in any event your attitude tells me your not interested in trying to reach a consensus so I will restate I used the term correctly and let this silly thread go. you can draw what ever conclusion you like.
