The Arriflex SR is a 16 mm movie camera product line created by Arri in 1975 to replace the Arri 16BL line. The SR stands for silent reflex, which means that it is a quiet sync-sound camera with a reflex shutter. The full official name is Arriflex 16SR; however, the lack of a camera designated Arriflex 35SR (unlike the 16BL and 35BL lines) has led to the camera usually referred to only by the SR designation. Its most similar 35 mm line is the Arriflex 535, which debuted in 1990. It is currently considered to be the most popular 16 mm movie camera in usage, due to its wide range of wide range of features, intuitive design, high reliability, modularity, and widespread availability for rental or sale. As such, it is considered the 16 mm industry standard, although Aaton's XTR series also commands a considerable percentage of professional usage. Arri has since debuted the Arriflex 416 in 2006 which is incompatible with the SR series, and may very likely begin to supercede the SR line in the next few years.

Models and technical data

(Most of the specifications noted apply forward to all successive models unless noted otherwise.)

435 and 435ES

Arri debuted two models of the 435 in 1995: the 435 and 435ES. The latter is suffixed ES to denote electronic shutter capabilities; this means that the shutter angle is able to be continuously electronically adjusted, even while the camera is running, and set to any angle within a specific range (11.2° to 180°) to a great deal of precision (0.1°). Otherwise, they are identical in all other respects. These include a standard Arri PL mount; compatability with Super 35; frame rates adjustable both in forward and reverse between 1 and 150 frames per second, accurate to .001 frames per second; fixed-loop magazines and backwards compatibility with older Arri magazines; full compatibility with Arriflex 535 accessories; timecode capability; and a highly flexible viewfinder and video-tap system which could be switched out with other video tap options.

Other accessories and capabilities were modularly added in successive years, including Steadicam magazines (1996), an integrated video assist (1997), 1000 foot magazines and single frame control (1998), and 3-perf movement (2000).

435 Advanced

The 435 Advanced was unveiled in 2001 and was the result of several years of feedback from users of the 435 system. While not only making standard some of the improved accessories made available in the interim, the 435 Advanced added more features to increase the versatility of the camera. These included a lower minimum frame rate of 0.1 frames per second, motion control integration with Arrimotion, and LDS (Lens Data System) lens recognition capability through electronic sensors.

435 Xtreme

A new FEM (Functional Expansion Module) was added in 2003 to increase the camera's electronic feature set. Arri integrated this into the new 435 Xtreme, which was released in 2004. The new functions included faster ramping speed capability, a wider ramping range which could go down to 0.1 frames per second, further motion control interface abilities, integrated lens electronics, and integrated wireless radio signalling.

Three more accessories were released in 2005, exclusively for the 435 Advanced and 435 Xtreme: a hand-crank extension, a timing shift box to offset the phasing, and a remote LCD control panel designed for use on the "dumb side" of the camera.
