In the world of photography, there is a particular type of lens about which most photographers get excited, the pancake lens.
A pancake lens is a colloquial term for a lens that's shorter than it is wide – hence looking like a 'pancake'. Due to their compacted dimensions, pancake lenses are always fixed focal length ('prime') lenses and much smaller and lighter than a regular lens.
When Fujifilm first announced the Fujinon XF27mmF2.8 lens in 2013, many photographers were excited because it was the first pancake lens for the system.
Some may think that 27mm is a weird focal length. However, I think it is the perfect "normal" focal length. Normal is defined as the diagonal dimension of the film frame or image sensor. The math works out as follows:
- 35mm full frame sensor dimensions are 36mm x 24mm; diagonal is 43.27mm.
- Fuji GFX sensor dimensions are 43.8mm x 32.9mm; diagonal is 54.78mm; crop factor is 43.27/54.78 = 0.78988682 or ~ 0.79.
- Fuji APS-C sensor dimensions are 23.6mm x 15.6mm; diagonal dimension is 28.29mm; crop factor is 43.27/28.29 = 1.5295157299 or ~ 1.53.
This lens has high image quality and excellent build quality. But it isn’t perfect. The Fujinon XF27mmF2.8 is a plastic lens and has no aperture ring. Additionally there is no manual-focus override. There are no controls other than the focus control ring.
I switched to the Fujifilm X system because the system offers camera and lenses that offer quick access to the triangle of camera settings, ISO, aperture and shutter speed. The Fujinon XF27mmF2.8 disappoints in that regard. While it’s easy enough to map the rear command dial to change aperture settings for this lens, the process breaks my current working style as it requires learning some new muscle memory.
The Fujinon XF27mmF2.8 lens has no lens hood because a pancake lens with a lens hood defeats the purpose of a pancake lens.
I have mixed feelings about the Fujinon XF27mmF2.8 lens. I appreciate the compact nature of the pancake lens and fast autofocus. The 27mm focal length (~ 41mm full-frame) is ideal for street photography; however, the lack of manual-focus override and no aperture ring limits it's overall usefulness to me. If Fuji were to release a lens at this focal length with an aperture ring, I would seriously consider purchasing. In the meantime, I make do with my manual focus Asahi Optical Co. Super-Multi-Coated Takumar 28mm f/3.5.
You have to move a switch on your camera to get to or from manual focus mode and move a dial on the camera to change the aperture.
