LA-based Optica Magnus, which specialises in anamorphic conversion and lens expanders (which allow lenses with small image circles to be used on large sensors), is starting to ship the first of its new Full Frame Finders.
The large-format traditional-style director’s viewfinder is a lightweight, ergonomically designed optical system, using bright ground glass that offers both spherical and anamorphic capabilities (with easy changeover), with squeeze factors initially of 1.5x and 1.9x (1.9x covers 1.8x and 2.0x squeeze factors). Customised anamorphic modules are available on request.
The viewfinder is compatible with all sensor formats up to Red Monstro 8K (image diameter 46.31mm – including Super35, full frame, VV and LF). It offers interchangeable lens mounts, using the P+S Technik Interchangeable Mount System (compatible with PL, LPL, Leica R, Nikon F, Panavision, Canon FD and professional Canon EF mounts). Users can attach any cinema lens to get a true rendering of the image.
The viewfinder “has the unique capability to display any frame-line arrangement the user desires, to suit the camera sensor size and post-production image extraction requirements”, according to its European distributor, P+S Technik.
Custom frame lines can be printed using a laser printer, onto clear high temperature resistant polyester film, which is then cut out and inserted in a slot in the side of the viewfinder in front of the ground glass, to cover all the different image sensors and aspect ratios. Users can create the necessary frame lines with the provided app. The Frame Line Composer application is available for Windows and Mac, and the system means users can save money as only one ground glass is needed.
The Finder has a pivoting handle grip for counterbalance, and an adjustable eyepiece diopter (which is changeable for Super35 and full format view).
The Optica Magnus Full-Frame-Finder (IMS 2.0 PL-mount and spherical module included, with full format eyepiece) costs €9900. An optional HD video assist system is expected later in the year, as are the anamorphic modules.
