(INSERT SINGLE HERO IMAGE HERE - other images below in media section)
The Leica R lenses were part of Leica’s line of 35mm single-lens reflex (SLR) cameras. These started with the Leicaflex cameras in 1964 and continued through the Leica R-series cameras, until production ended in 2009. As the lenses were originally designed to cover the 36mm x 24mm film area, these lenses cover full frame cine cameras.
Even though the Leica R cameras discontinued, the Leica R lenses live on till today as they can be adapted for use on various digital mirrorless systems due to their excellent optical performance.
The Leica-R lenses are renowned for their sharp, non-clinical resolution mixed with good contrast and subtly warm colours. The bokeh is smooth when wide open, but still produces the iconic look when stopped down. This is the reason why TLS use the original iris during the rehousing process.
The TLS rehousing make the lenses suitable for modern filmmaking and cinematography. The rehousing process is also designed to improve their functionality, such as adding smoother focus and aperture mechanisms, as well as standardising lens housing to fit professional cine lens mounts and accessories.
