Magic Lantern is a firmware add-on for various Canon digital single-lens reflex (DSLR) cameras and the EOS M. [2] It adds features for DSLR filmmaking and still photography, and is free and open-source. Magic Lantern was originally written for the Canon EOS 5D Mark II [3] by Trammell Hudson in 2009 after he reverse engineered its firmware. [1]
Zenit 122 Zenit-4 with leaf shutter Zenit-16 with vertical travel shutter. The first attempt to make high-end professional camera by KMZ was the Start in 1958. This camera had a full set of shutter speeds (from 1 sec to 1/1000), a lens with an automatic diaphragm in a unique breech-lock mount, and even a knife for cutting-off part of the unexposed film.
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
The centre of the diaphragm's aperture coincides with the optical axis of the lens system. Most modern cameras use a type of adjustable diaphragm known as an iris diaphragm, and often referred to simply as an iris. See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the ...
A "pre-set" diaphragm had two aperture rings next to each other: one could be set in advance to the aperture needed for the picture while the other ring controlled the diaphragm directly. Turning the second ring all the way clockwise gave full aperture; turn it all the way counterclockwise gave the preset shooting aperture, speeding up the process.
Live preview on LCD. The concept for cameras with live preview largely derives from electronic TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.

[7] It features the Expeed 4 processor and is the company's first DSLR with built-in Wi-Fi and GPS. It shares the same 24-megapixel image sensor as its D5200 predecessor, but without an anti-aliasing (AA) filter, [8] equal to the Nikon D7100. MSRP for the body is $800, and $1,400 with an 18–140mm f/3.5-5.6 kit lens. [9]
