The Tri-Elmar is a top performer wide angle zoom
lens. This makes a 21-24-28mm lens on the Leica M8.
Performance at 21mm are similar to the Elmarit-M
2.8 21mm except that the later can open at f:2.8.
A new universal wide angle finder with parallax
correction is available.
IR Filter : complicated
To put an IR filter on this lens is not a straight
forward task, it is necessary for this to use an
adapter and a 67mm diameter filter. This make some
sort of bulk filter ahead of the lens without any
sunshade. To prevent reflection through viewer
opening in the adapter, a special mask with a hole
is available. Not a nice solution indeed. By chance
custom made solution like Milich adapter exists. It
is a custom made filter adapter with sunshade built
in. I had no occasion to test this solution but it
is said to work well.
Finder bright line frame precision : not so
After having used this finder it appears that it is
in a small proportion miss-aligned and tends to
make the picture too much on the left side.
The short distance parallax correction makes the
marks in the finder move vertically (finder is in
the same vertical plan as the lens, so no
horizontal adjustment necessary).
Round dot window on top :
The little round white glass on the top of the
finder brings lights to the bubble level. It
appears that this white glass is photosensitive and
gets green when strongly lightened so it emits some
light when in the dark making it easier to see the
