Photographic apparatus

A photographic apparatus comprising:

• an objective including a front lens unit for forming a first object image at a position of finite distance, and a rear lens unit cooperating with said front lens unit to form a second object image of different magnification from that of said first object image;
• dividing means arranged between said front lens unit and said rear lens unit, for dividing a first light path of said objective into second and third light paths;
• observation means, arranged on said second light path, for observing said first object image;
• and
• image receiving means, arranged on said third light path, for receiving said second object image, wherein said front lens unit is a zoom lens and said front lens unit and said rear lens unit are arranged to satisfy the following condition:
• 0. 6<Fa/F<0.97
• where Fa is the shortest focal length of said front lens unit, and F is the shortest focal length of said objective system comprising said front and said rear lens units. PG,18

A camera comprising:

• a front lens unit including a plurality of sub-units axially movable in differential relation to form a first object image at a position of finite distance;
• a rear lens unit cooperating with said front lens unit to form a second object image of different magnification from that of said first image;
• beam splitting means positioned in a space between said front and said rear lens unit to split an optical path;
• a viewfinder positioned in the optical path of the split-off light to observe said first image of the object and including a roof type prism and an eyepiece;
• and
• an image receiver on which said second image of the object is formed, wherein said front lens unit and said rear lens unit are arranged to satisfy the following condition:
• 0. 6<Fa/F<0.97
• where Fa is the shortest focal length of said front lens unit, and F is the shortest overall focal length of said front and said rear lens units.

A photographic optical apparatus comprising:

• dividing means for dividing a first light path into second and third light paths;
• image forming optical means, arranged on said first light path, for forming a first object image on said second light path and a second object image on said third light path;
• observation means, arranged on said second light path, for observing said first object image;
• and
• image receiving means, arranged on said third light path, for receiving said second object image, said first object image having a smaller magnification than said second object image, wherein said image forming optical means has a front imaging lens unit on the object side of said dividing means and a rear lens unit of negative refractive power between said dividing means and said image receiving means.
