Panasonic Lumix G X Vario PZ 14-42mm F3.5-5. This list is incomplete you can help by adding missing items. Due to this compromise in design, body-cap lenses generally suffer from numerous image quality issues such as heavy vignetting and poor image sharpness.Įxamples of body-cap lenses include the Olympus Body Cap Lens 15mm f/8 and the Fujifilm XM-FL 24mm f/8. These lenses generally have no more than a couple optical lens elements, no image correcting elements, a very-slow fixed aperture, an extremely thin focusing ring (if any), and a retractable lens element cover. This varies greatly depending upon the lens' build quality, focal length, and maximum aperture.Ī body-cap lens is an extreme type of pancake lens that is designed to both protect the camera internals as a body cap normally would, yet still allow the user to take photos. While there is no specific size and weight in defining a pancake lens, most are light-weight and no more than a few centimeters in length. Because of this limitation, pancake zoom lenses are much less common. Pancake-style prime lenses are generally simpler to manufacture than pancake zoom lenses like Sony E PZ 16-50mm F3.5-5.6 due to the general lack of an internal micromotor and fewer image correcting elements, allowing for a thinner profile. This has necessitated the design of retrofocus lenses that refocus the image farther back, which is why such lenses are longer and bulkier than their "pancake" equivalents. In such a situation, a pancake lens focuses in front of, rather than on, the focal plane (film or light sensor) of the camera. The problem arises when such lenses have too short a focal length to fit in front of the retractable mirrors used in reflex cameras.
Pancake lenses can be very short and flat because they do not need large amounts of optical correction, i.e. The resulting camera and lens assembly may even be small enough to be pocketable, a design feature which is usually impractical with conventional SLR bodies and lens assemblies.
