In general, the single lens or non-stereo Iloca cameras were well built and quite robust. They were generally straight-forward to operate and even the most basic configurations were capable of producing quite acceptable photos in most cases.
Here is a list of the most common single lens cameras produced by the company:
Iloca single lens cameras were available with various lens/shutter combinations, not to mention the variety of body configurations - with or without rangefinders, lightmeters, accessory shoes etc. Every so often, another version seems to pop up that is slightly different in some aspect to the other known models.
Early models (Iloca I / Ia and II / IIa) require removal of the base in order to load the film, which has to be inserted (complete with take-up spool) from the bottom of the camera. This can be a tricky procedure to ensure that the film is correctly located on the film sprockets. As a result, these early models gained a reputation as being somewhat problematic. Later models had removable camera backs which simplified the loading process considerably (although the idiosynchratic procedures for releasing the various camera backs are another matter altogether - simple once you know how!)
In their day, the Iloca range of models would have appealed to buyers looking for a decent quality camera at an affordable price. Some models offered a choice of lenses, or faster shutters with a greater range of speeds. More advanced features appeared progressively on later models - features such as built-in lightmeters and coupled shutter/aperture settings. The company's final effort was the ambitious and relatively high specification Iloca Electric, with electric motor drive and a choice of interchangeable lenses. This model (along with its Graflex Graphic 35 Electric counterpart) was the most expensive Iloca model produced, and is generally acknowledged as the first production camera with electric motor drive.
In addition to this list, there were many variants produced under different brand names such as Realist, Graflex, Tower, Argus, Photrix and MPP/Iloca.
