Abstract

The Kenworthy Snorkel Camera System is a "periscope" type of lens system designed for use in cinematography. Its primary applications are in the photographing of small scale models and in close-up work. Since its introduction in 1967, the system has been used extensively for these purposes, and has been especially useful in advertising work. It was hypothesised that the system could be modified without any loss in image quality by changing the relay system from a single relay lens to a telecentric relay system composed of two equal focal length lenses. A diaphragm could also be added to the system (placed between the relay lenses) with this relay set-up. If these modifications could be made, then the versatility of the system could be increased. The modifications were made to the system, and the subjective results point towards the hypothesis being true. However, in the final analysis, the hypothesis could not be proven true because the appropriate data could not be gathered. This was due to the fact that this lens system requires extremely exact alignment of the optical components. Unfortunately, it was beyond the scope of this work to build a final modified system which could be aligned with the degree of accuracy required.
