The large-aperture G Lens series brings together a wealth of
advanced technology to provide you with an exceptionally
refined level of optical performance. Its aspherical lens
elements improve lens performance; ED (Extra-low Dispersion)
glass minimizes the chromatic aberrations that occur at large
apertures; and the circular aperture makes smooth, beautiful
defocusing possible. The resulting difference in quality is clear
to see... and clearly breathtaking.

Modulation Transfer
Function (MTF)
MTF is a measurement of how well a lens
can reproduce fine details at a high level
of contrast. The curves below show lens
performance at two levels of spatial frequency
(10 or 30 line pairs/mm) for two types of
targets (radial R, tangential T). Performance is
measured at two settings: open and F8.
For each condition, contrast level changes at
various points away from the center of
the image.

35mm F1.4 G
Lens groups/elements: 8/10
Minimum focus: 11-13/16” (0.3 m)
Filter diameter: 55 mm
Size: (diameter x length): 2-3/4 x 3”
(69 x 76 mm)
Weight: 1 lb 2 oz (510 g)
Fast wide-angle lens with superior image quality at wide
apertures thanks to glass-molded aspheric lens elements.
Achieves high resolution and high contrast from corner to
corner, with shallow depth of field also possible because
of the large maximum aperture. This unique lens gives a
special touch to portraits and landscapes, and is ideal for
handheld shooting. For comfortable handling, includes a
focus hold button and a focus ring that does not rotate
during AF operation.
