EXTREME WIDE ANGLE
Reg. U. S. A. Pat. Off.
SERIES IIIa f 12.5
AN IDEAL INEXPENSIVE WIDE ANGLE LENS
The genuine merits and unlimited possibilities of the Series IIIa lens have gained for it a host of enthusiastic friends.
Its speed, extreme angle, reserve covering power and moderate price, offer a combination of qualities that should prove of real interest to the commercial photographer. For banquet camera work where space is limited and a short focus lens required, the Series IIIa will make a strong appeal.
The Series IIIa has an angle of view of 90 degrees and gives good definition at full aperture; wiry sharpness when stopped down. Because of its large circle of illumination this lens can be used on a plate a size larger than listed by stopping down the diaphragm. It then affords an angle of about 100 degrees.
