How to load an ARRIFLEX 16BL

#ARRIFLEX 16BL FOCUS PULLER RAJKARAN VERMA CAMERA NABRAJ KHADKA, RAKESH SINGH MUSIC NIRAJ K.C EDIT SUJAN BADAL EQUIPMENT CINEFOCUS POSTPRODUCTION CINEZONE Arriflex BL. Introduced in 1965, the 16 BL is ARRI' first silent 16mm camera. This model was originally designated he 16Q( Q for Quiet), and was renamed before it became available for purchase in early 1965. Film Transport and sound Reduction: The 16Bl uses the same film transport movement as the 16S and 16M . It is essentially a self- blimped 16M. Because this movement was originally designed for MOS camera, the entire 16BL is Blimped, hence the "BL" designation. The major difference in the movement is the relocation of the mirror closer to the lens mount, on order to accommodate the location of the ground glass in forward focal plane (right next to gate). The first models of the 16BLwere rated by Arri as having a noise level of 31dB at 3ft. The slightly louder than he ARI 16SR-I's rated noise level of 28 dB. The BL operates only with 400ft displacement magazines (very rare 1200ft mags and 400ftshouler mags exit). The mag were originally designed be ex-changeable between the 1BL and the 16M although the 16M mags are not sound-insulated. Because of a later design change in production cameras this should be avoided. It can cause damage o the magazine gears. Do not attempt to use 16M mag on a 16 BL. Optical system: Since the 16BL was designed to be used primarily with its blimped zoom lens, and these lenses have rear elements that do not protrude as much as the older prime lenses, Arri moved the shutter further forward toward the rear element of the lens. This allowed ARRI engineers to move the ground glass near the gate, rather than back into the viewfinder tube as in the Arri 16S and 16M. This is the arrangement used on all modern mirror reflex cameras (16mm and 35mm).The 16BL allows you to see beyond the frame lines of the 16mm aperture. This is very useful for keeping microphone booms and other objects out of frame. It is the first ARRI 16mm camera with a pivoting viewfinder. The finder is not "Orientale", which means that as you pivot the viewfinder, the image rotates. There are two viewfinders, a small standard viewfinder and the "Swan" viewfinder which makes hand holding the 16BL much easier. The finders can be removed from the camera and exchanged easily. This feature is not available on 16BL's before serial No. 50701. Lens Mount: The 16BL introduced the ARRI Bayonet lens mount. This lens mount differs from the ARRI standard lens mount in that it is made of Stainless steel, and has two "Bayonet Lugs" that lock into specially milled channels in the inside bore of the Bayonet mount. The Bayonet mount is much stronger than the original aluminum ARRI Standard lens mounts and holds much better tolerances for the lens/camera interface. The Bayonet mount is backwards compatible, for mounting ARRI Standard mount lenses. Zoom Lenses for the 16BL: The 16BL came factory equipped with a zoom lens. The following lenses were offered: Manufacturer Lens Model/ Design Focal Length T-Stop(some are variable)Angenieux-Zoom 9.5-95mm T2.8 Angenieux-Zoom12-120mm T2.5 Angenieux-Zoom10-150mm T2.3-3.2 Ziess vario-Sonnar 12.5-75mm T2.4 Ziess Vari-Sonnar 10-100mm T3.3 Each lens is mounted inside a lens blimp which couples with the 16BL. All of these were the original non-multicoated versions. TIP: One way to get the best optical performance with a 16BL is to replace the original lens with the newer multicoated version, that gives you the performance of a new lens and still fits into the lens blimp.
