How CPU/Contact works
1. Exif Data
Picture can store the Exif data of lens.
(For example, if you use Voigtländer 110mm F2.5 E-mount)
Lens
E 110mm F2.5
or
Voigtlander MACRO
APO-LANTHAR 110mm F2.5
* Description may be changed depending
on firmware version or other factors.
Focal length
110mm
Maximum Aperture
F2.5
Aperture
The aperture value you used to take
the picture
* Some camera bodies can not transmit data correctly.
2. Lens Correction Data
The lens stores the data for lens correction. You can set Auto Lens
Correction on camera bodies;
Fall off
Auto / Off
Chromatic Aberration
Auto / Off
Distortion
Auto / Off
* On some camera bodies, you can not choose Auto Lens Correction Mode. In
that case, a setting depends on the camera.
