• F value: 5.82-8.24
• Half angle of view: 11.86-3.19
• Image height: 21.64
• Overall length: 183.21-258.38
• Back focus: 39.88-81.93

Example 2

• Focal length: 153.00-581.90
• F value: 8.00-11.31
• Half angle of view: 8.05-2.13
• Image height: 21.64
• Overall length: 274.81-354.89
• Back focus: 68.40-126.51
