This page strives to comprehensively document the basic specifications and production date range of all Wollensak lenses and shutters made for commercial still cameras from 1899-1972. The information is drawn from this list of original Wollensak product catalogs, price lists, product brochures, and other resources. I am always looking to fill in missing information and correct any errors, so please do not hesitate to contact me with suggestions or additional references.
Lenses are listed alphabetically by series, followed by shutters. Use the table below to jump directly to a particular series of lens or shutter.
WOLLENSAK LENSES FOR COMMERCIAL STILL CAMERAS
A note on lens coating:
Wollensak developed a hard-coat anti-reflection single lens coating during around 1943 and began offering the coating commercially at an extra charge in 1946. Beginning in 1947, this “Wocote” lens coating was standard on all Wollensak lenses for commercial cameras. All of Wollensak’s Raptar lenses are single coated. Coated lenses sold on contract to the armed forces were marked with a yellow dot, while other coated lenses were indicated by a stylized letter W-in-a-C Wocote logo (shown at right).

Extreme Wide Angle
Series Notes: Catalogs variously describe the angle of view as 90 to 100-degrees and advise that the lens be stopped down to f/32 for “sharp definition to the extreme corners” of the plates sizes listed below. Replaced by the Extreme Wide Angle Series IIIa in 1922. These lenses lack serial numbers.

Extreme Wide Angle Series IIIa
Series Notes: 90-degree angle of view, increasing up to 100-degrees when stopped down. Convertible using single cells. Replaced both the Extreme Wide Angle and Symmetrical Wide Angle series of lenses. Not anastigmatic at f/12.5 (which is why this lens was not given the Velostigmat name), but becomes an anastigmat when stopped down to f/18. See Lensology and Shutterisms Vol. 10 No. 4 p. 5. Serial numbers followed the Series IIIa sequence until 1942, and the Anastigmat Series thereafter.
The 4/2 design was discontinued in favor of a new 4/4 design in 1946 with the advent of lens coating (see Raptar/Anastigmat/Velostigmat Extreme Wide Angle below). Although catalogs refer to this line of lenses as the “Series IIIa Extreme Wide Angle” before and after the design change, the earlier 4/2 lenses are distinguished by being uncoated and engraved as “Series IIIa EX. W.A.”

Optar
Series Notes: Wollensak began producing Optar lenses for Graflex in 1942. Optar was a Graflex trade name, but Optar lenses in Graphex shutters are essentially the same as Wollensak’s own Velostigmat and, later, Raptar lenses in Rapax shutters. Optar Serial numbers followed the Anastigmat Series from 1942-1953, and the separate Optar Series from late 1953 onward.

Pro Raptar
Series Notes: These Plasmat-design lenses were Wollensak’s final major consumer product innovation. Produced in 1970 and possibly adapted from the earlier, eponymous line of enlarging lenses, Pro Raptar lenses were single-coated (despite the absence of the “Wocote” symbol) and factory mounted in blue-faced Rapax #3 shutters. Serial numbers follow the Anastigmat Series.

Raptar Extreme Wide Angle (also called the Velostigmat Extreme Wide Angle, Anastigmat Extreme Wide Angle, and the Raptar Series IIIa Wide Angle)
Series Notes: Design and stated coverage are similar to the Raptar Wide Angle f/6.8 lens, but the Extreme Wide Angle is lower-priced due to the smaller maximum aperture of f/12.5. Replaced the Series IIIa Extreme Wide Angle lens in 1946 with a new 4/4 design. Although catalogs continued to refer to this line of lenses as the “Series IIIa Extreme Wide Angle” before and after the design change, the later 4/4 lenses are distinguished by being coated and engraved first “Velostigmat Extreme W.A.”, then “Raptar Extreme W.A.” and later “Anastigmat Extreme W.A.” Serial numbers follow the Anastigmat Series.

Raptar Wide Angle
Series Notes: Wollensak literature recommended that the lens be stopped down to f/11 or smaller to give acceptable definition. The design and stated coverage of the f/6.8 are similar to the lower-priced f/12.5 versions engraved “Velostigmat Extreme W.A.”, “Anastigmat Extreme W.A.” and, later, “Raptar Extreme W.A.” on the lens. Serial numbers follow the Anastigmat Series.

Veritar
Series notes: Soft focus portrait lens, successor to the Verito. The Veritar is the same 3/2 construction as the Verito, but with coated elements and designed to offer softness at f/6 comparable to the Verito at f/4. Convertible using rear lens cell alone.

Verito
Series notes: Likely the best-selling and most widely used soft focus lens of all time. The Verito was adapted from the Bodine Pictorial Lens around 1911 and remained in production until 1946. Updated, coated, and replaced by the Veritar in 1950. The rear cell can be used alone at nearly twice the original focal length. The Verito barrel was finished in polished brass with black trim until 1915, and in black enamel thereafter. The Verito was redesigned in 1920 to reduce halation and align visual focus with chemical focus, as well as to offer softness at f/4 equal to the prior design’s softness at f/6. The redesigned Verito eliminated diffusion stops, with softness controlled solely by means of aperture adjustment; see page 11-13 of Lensology and Shutterisms Vol. 8 No. 4 for details. Wollensak’s f/6 Verito A and B, as well as the Verito Motion Picture lenses, are a different 2/2 periscopic design. Serial numbers followed the Verito Series until 1942, and the Anastigmat Series thereafter.

Studio
Series Notes: Wollensak’s solution to shuttering very large portrait lenses, the Studio shutter was designed in Style “A”, which attached behind the lens, and Style “B”, which screwed in place of the original lens diaphragm to offer both aperture and shutter control. The Studio shutter’s only speed is Bulb, with instant exposures as short as approximately one-fifth of a second. A cable release attachment replaced the bulb-and-hose pneumatic actuator in 1916. Around 1926, the cable release attachment on the No. 5 shutter was replaced with a dual cable release/bulb release attachment.
