by Bausch and Lomb
NEXT TORONTO MEETING:
Wednesday, Dec. 17th, 2014
ANNUAL SHOW AND TELL
In a few short weeks it will be time again for another popular Show & Tell evening at PHSC. Members can and do bring all sorts of unusual items for show and possible identification. If you have an item, please let Clint know so he can add you to the list! He can be reached at: fair@phsc.ca.
As usual, we will have our traditional gift exchange. Bring a gift of about $15 of interest to a member to participate – President Mark Singer will bring his Christmas Tree. During the evening, we will have another excellent silent auction too, so bring lots of spare change!
The public is welcome. Go to our Programs page for times and directions.
By the way, in the above icon, I show an 1890s lens called a Zeiss Anastigmat, licensed to the maker, Bausch and Lomb, in Rochester NY. It is marked as series V with a full plate (8.5 x 6.5 inches) coverage. The Series V mark denotes an extreme wide angle design.
The Anastigmat was renamed Protar after Zeiss lost a court battle (Zeiss used a capital A in anastigmat to attempt to trademark the name). The series V wide angle Protars continued to be manufactured into the 1930s.
The Paul Rudolf designed Anastigmat was a milestone event in photographic history. By using a then new type of Schott glass, Rudolf created a lens free of astigmatism allowing a true flat field at the film plane for the first time.
And the reason this Zeiss lens was made by Bausch and Lomb? Come out to the meeting to hear or read the magnificent Zeiss and Photography just released by Larry Gubas.
