The series V was one of the original anastigmats from Zeiss and remained in production for several years, Ross advertised the lens until World War I. The aperture when first introduced was f18 in the later 1890s this was increased to f16. The range at this time, by Ross, was from 86 to 1660 mm. The lens was intended for interior work and in the larger sizes for copying and process work.

The series VIIa is the best known of the Protar range. The series VII is made of four glasses the VIIa or Double Protar is made of two symmetrically arranged groups of the series VII. The two groups need not have the same focal length. In Britain the lens was made under licence by Ross in lengths of 4 - 42" for the VII giving combined lengths from 2 ⅜". Until 1900 the Protar was known as the Zeiss Anastigmat.

This is one of the symmetrical Protars and is different to the earlier Zeiss Anastigmat series IV. It consists of two symmetrically arranged groups, each group can be used separately. In Britain the lenses were made under licence by Ross in focal lengths of 150 - 700 mm for the single group giving 87 - 407 mm combined. The series IV replaced the series VI. For one year - 1908 - Newman & Guardia advertised the Square Reflector with the newly introduced Series IV Protar. This example has an unusual mount fitted with an outside bayonet to attach to the camera. the mount is marked 7" and 14".

Convertible Anastigmat

f6.8, 8 ½" combined; 16" separated. Iris diaphragm with external pointer to f64. Brass mount.

Notes:
It is not clear what this lens is. It carries the Zeiss name but the engraving does not appear to be by Zeiss and there is no serial number. Possibly the lens is a rapid rectilinear with a fake inscription.

The original Anastigmats were introduced in 1890 and consisted of an old formula achromat at the front and an achromat using the new Jena glass with two or three elements at the rear.
