Maximum Compatibility

Leica engineers were careful to ensure that the new M series—like its predecessors—remains compatible with existing series. This means that objectives, bases, tubes and so on can be reused.

Objectives

All new objectives of the M series are parfocal, meaning that when used with the objective nosepiece, they can be replaced while keeping the specimen in perfect focus.

If you prefer, you can continue to use the previ- ous objective series. In this case, parfocality is no longer guaranteed.

Tubes

The interface between the optics carrier and the tube has remained the same, so existing tubes fit the new M series. The new tubes are designed for eyepieces with field number 23, while the predecessor models were only designed for field number 21, resulting in a smaller object field.

Eyepieces

However, the new M-series eyepieces models have an audible and tangible click to provide immediate feedback in case of accidental adjustment.
