Diana F+ Lens Adaptors - Adjust the View
20 38 Share TweetDiana F+ Lenses can do a whole lot of fantastic things but they won´t overrule physics. Your film or sensor format sets the boarders to the lenses field of view…
The field of view you get from a lens depends on its focal length and the format the film/camera sensor has. If you use your Diana F+ Lenses with the adaptors you´ll propably use them on a 35mm Camera instead of a medium format snapshooter as the Diana is one, and yet the film size has changed – which results in a cropped exposure.

The bigger the film format or camera sensor, the bigger the picture angle will be – which on the other hand means the smaller your film or sensor the smaller the angle of field of view cought on film will be. That´s why you don´t get a full fisheye effect when using the Diana F+ fisheye lens on a 35mm SLR camera. For digital SLRs with non full-size APS-C sensor the crop-factor is even bigger than for 35mm film. To get an idea of what each lens will do on a 35mm and APS-C sensor camera we did some math for you.





Note: The focal length of a lens won´t change if you use different film formats but the film format determines which part of the image is on film! What happens can be compared to what´s known as crop factor – when you are using a 35mm SLR lens on a digital SLR camera with APS-C or similar sized sensors.
