The image forming lens flips the image once. For the imaging sensor, there is one flip. The viewfinder is made up of a fold mirror, the one in the mirrorbox of the camera, a focusing screen, and either a pentaprism or two mirrors. The fold mirror flips the image once, restoring it to "normal" parity. This means there are two inversions in a waist-level ...

The mechanical on-off switch is certainly more endangered than the camera's internal auto-off, aside from the induced movement of the camera by using it. I leave my cameras on all the time, often for multiple days during travel. It does not bother them; the auto-off is set to 1 min and when you touch the shutter they come back on right away. i think this is ...

Honestly, I am not sure you will keep more power if you turn off the camera between shots but you will most likely have more issues by doing it. Timelapse are best done with as much consistency as possible between shots. So any movement is potentially problematic. Already I would suggest a remote trigger rather than using the shutter-release yourself. Now, ...

From my experience, letting the exposure metering time out and turn itself off is the same as turning off the camera completely and there's no noticeable difference in battery drain in either case. You can tell when the metering is off when the shutter speed and aperture setting numbers disappear from the viewfinder display. There are external triggers that ...

It's a gamble. In most cases, you won't need the warranty — but in the cases where you do, you'd be sorry to not have it, because repairs can be expensive. If most cameras needed warranty repair, the manufacturer would go out of business; it's generally the case that quality assurance is pretty good out of the box and most cameras are buy-and-forget. There ...

The image forming rays from the camera’s lens are intercepted by a hinged first surface (reflex) mirror set at a 45⁰ angle. This first reflection rights the upside down image, but, being a mirror image, it is reversed right for left. This image is projected onto a viewing screen. The bottom side of this screen has been roughened by scrubbing it with fine ...

It depends on your level of expertise in judging what lenses you need. If you are a complete beginner who doesn't know what all those letters and numbers on the lens actually mean in practical shooting terms, and you're getting a entry-level dSLR body, then get the 18-55 kit lens (or if you're shooting four-thirds, 14-42 kit lens :-). Knowing what lens to ...
