Symmar
The Symmar is one of the original Schneider designs, introduced in 1920, and is still relevant and used today. They have a 6-element, 4-group, symmetric design, and give a 70° angle of coverage. These lenses are "convertible", meaning that by removing one of the lens cells the user creates a 3 element lens of longer focal length than the complete lens. The resulting 3 element lens has a smaller maximum f-number. These lenses have two aperture markings, one in white for the complete lens and one in green for the converted lens. When "converted" the resulting 3 element lens will produce softer images than the complete lens.

- 150 mm f/5.6
- 180 mm f/5.6 (for 5×7 in)
- 210 mm f/5.6

- 300 mm f/5.6
- 360 mm f/5.6 (for 11×14 in)
[edit] Symmar-S
The Symmar-S is an incremental improvement to the original Symmar design, adding multicoating to the feature set. The lens is not symmetric like its predecessor and is not convertible. The available focal lengths are slightly different, with the subtraction of the 80 mm, and addition of a 120 mm and two 480 mm lenses of varying speeds.

[edit] Apo-Symmar
This is a 6-element, 4-group
apochromatic lens design, which has since been replaced by the Apo-Symmar L-Series. Using low-dispersion glass and multicoating techniques, secondary-spectrum reflections have been greatly reduced. The Apo-Symmar lenses up to 360 mm have a 72° angle of coverage, and the 480 mm lenses give a 56° angle.
