Lens Mapping
This section covers the lens mapping function of Hedén Ymer-3.
Ymer-3 have lens mapping function on the focus channel, the unit have four different storage positions for storing lens data
internally. The focus mapping function elliminates the need to manually mark separate rings for each lens.
To map a lens to the scale ring, select one of the pre-marked scale rings, the lens mapping function matches the focus
distance of a lens to a pre-marked lens ring.
The lens mapping is made by selecting a pre-marked scale ring and then by matching up to 20 marks on the lens with the
corresponding marks on the pre-marked ring. It’s possible to use less than 20 marks, but in general more marks will give a
better results. The mapping is done by moving the motor to a mark on the lens, then pressing the AUX button and moving
the scale ring to the corresponding mark, the process is described in more detail below.
After mapping the lens, it will be matched to the pre-marked scale ring used.
