A photographer is above all someone who looks. It is their socially accepted voyeurism that is significant, not their images. Voyeurism requires a safe distance, a vantage point for the observer beyond the reach of the observed (much like a movie audience, watching but not accountable). In Rear Window, the photographer is cut off not just by the lens of his camera, or by the glass window of his apartment, or indeed by the abyss of the courtyard across which he stares. It is his professionalized looking, with its fantasy of objectivity, that cuts him off. It demands his separation from the world. Despite witnessing what he believes is a murderer covering his traces, he feels no urge to get it on film. Rather, he uses his camera’s long lens as a telescope to watch, swapping it for binoculars when things get really intense.

The 35mm film camera used by Jeff is an Exakta VX Ihagee Dresden, with the Exakta logo covered by a piece of black material in the movie. Why choose the Exakta? In the time the film was shot, there were really only three 35mm camera systems with global recognition: Leica, Contax, and Exakta. Hitchcock could have used a Leica with a reflex housing for the telephoto lens (e.g. Visoflex II), but a solution with a one-eyed reflex with a prism viewfinder was more elegant. Why was the brand covered with black tape? To cover up its East German / Communist origins? This may have played a role, but more likely just an avoidance of advertising in film.
The Exakta is an interesting choice of camera for the period, made by Ihagee Kamerawerk Steenbergen & Co, Dresden, in former East Germany and was produced between 1951-56. The Exakta is notable as being the first ever Single Lens Reflex (SLR) camera for both 127 roll film (1933), and 135 format 35mm film (1936). It’s not surprising that Jeff was using a Exakta, as before Japanese started to dominate the camera market the Exakta dominated the market, capturing perhaps 95% of SLR sales (they did kind of invent the SLR in 1936). The lens being used on the camera is a Kilfitt Fern-Kilar f/5.6 400mm telephoto lens.
