Most designs had an upper lens which provided the view on a focusing screen that was the same size as the film and a lower lens to focus the image. Vertically transported 2 1/4 (120) roll film was most common, but others used 620; some 127, and there was at least one that used 35mm film which moved horizontally. Both lenses racked in and out as you focused and the lower could be stopped down, but the upper remained fully open. Few designs provided interchangeable lenses, the Mamiya C series being an exception. Some 35mm designs placed the lenses side by side.
As with any camera design where the viewing and image systems are not one and the same, there is a degree of parallax. Some tripods built for TLR's had a means of raising the lower lens to the position of the upper before the picture was made in an effort to reduce parallax. Another disadvantage was that there was no way to preview depth of field as the viewing lens had no aperture. However, they were popular waist-level cameras (less intimidating to people who were subjects) and could synchronize with flash at any shutter speed because of the leaf shutters they used.
DSLR = Digital Single Lens Reflex It's a digital camera made to look like a 35mm SLR. Usually the lens is interchangeable, but not always. - - - - - It is a camera with a detachable lens for great shots Hope this helped
it should be around $135-$140 ☺
Helmut Newton used the Rolleiflex twin-lens reflex (tlr), a 2 1/4 square medium format camera, for much of his professional work, although he reportedly did some work with a Hasselblad and the Pentax 35 mm. Newton claimed his favorite camera was the Olympus Stylus Epic, an inexpensive little point-and-shoot that is still being manufactured. To view both the Rolleiflex and a Stylus Epic, see Related Links, below.
A speed camera work when a driver is on high speed then the speed camera will take a shot of the car witch will have the number plate then they will be able to find all the information on the driver…
Yes, the kit will work with your iPod. EDIT: It does, but I couldn't find a way to actually read the files on the camera.

No. It's a single lens reflex digital camera.
Single Lens Reflex camera
reflex mirror
It means Single Reflex Lenses
SLR stands for a single lens reflex camera. Unlike a point and shoot camera, you can change lenses and are able to view your subject through the lens.
just work for them

A Digital Single Reflex Lens or DSLR is a type of camera which uses a series of mirrors inside the camera, so that when you look inside the viewfinder of a DSLR, then you will see almost precisely what the camera sensor sees, accurate to a few thousandths of a millimetre. This construction of the mirrors makes the camera more expensive to make, and most cameras simply use the easier and cheaper method, digital viewfinders, which only work when the camera is turned on, whereas on a DSLR, you can look through it anytime (as long as the lens cap is off!)
SLR stands for Single Lens Reflex. It means that the lens is removable and interchangeable. It also means that you're getting better picture quality as well as a faster shutter speed. Typically with an SLR there is a larger image sensor inside the camera that doesn't compress the photo as much as a simple point and shoot camera would.
