Nikon E2 - E2S - Manual (Page 73)

Usable lenses
iMost AF Nikkor lenses, Al-type Nikkor lenses and Teleconverters
can be used.
Nikkor lenses are designed to provide full coverage of the 35mm film
format (24mm x 36mm). The CCD in the E2/E2s is 8.7mm x 6.8mm,
which is smaller than the 35mm format, In order to provide you with
the full angle of view which you associate with your use of Nikon
35mm cameras for each usable Nikkor lens, the E2/E2s incorporates
high-quality image size reduction optics. To ensure lens
performance commensurate with Nikon’s customarily high
standards, only the lenses listed in the following chart are regarded
as usable with the E2/E2s camera’s image reduction system.
■Maximum lens apertures
The E2/E2S does not use the Nikkor lens’ aperture for exposure
control. The lens’ aperture remains open all the time for the brightest
viewing. Instead, an aperture is built into the camera’s image
reduction optics. The maximum aperture available is indicated in the
following table.
Lens max. aperture Available aperture range
f/1.2tof/5.6 f/6.5 to f/38
Slower than f/5.6 to f/7.3 f/8 to f/38
Slower than f/7.3 to f/9.5 f/9.5 to f/38
Slower than f/9.5 Max. aperture value* to f/38
Apertures can be set in 1/2 step increments.
Apertures outside the above range cannot be set.
The depth-of-field that you see in the viewfinder is controlled by the lens’
aperture. The actual depth-of-field for the picture will be controlled by the
image reduction optics’ aperture. Therefore, the actual depth-of-field will
be greater than that seen in the viewfinder.
