- Example 2: 72.08-291.36 f/4.6-5.8
- Example 3: 72.08-291.36 f/4.6-5.8
- Example 4: 68.47-291.36 f/4.6-5.9
- Example 5: 103.00-388.00 f/4.5-5.8
- Example 6: 102.81-388.73 f/4.6-5.8
- Example 7: 72.11-388.00 f/4.1-5.8
- Example 8: 154.50-582.00 f/5.1-6.4
- Example 9: 154.50-582.00 f/5.0-6.4
- Example 10: 154.50-582.00 f/5.1-6.5
- Example 11: 123.50-592.46 f/4.9-6.5
All of them have an image circle's radius of 21.64mm, all of them include SR.
In short and using 'commercial' focal lengths and apertures:
- 70-300mm f/4.5-5.6: four examples
- 70-400mm f/4-5.6: one example
- 100-400mm f/4.5-5.6: two examples
- 120-600mm f/5-6.3: one example
- 150-600mm f/5-6.3: three examples
Theses lenses suffer from heavy focus breathing: at short distance the 70-300s become 70-160s, the 70-400mm becomes a 65-145mm, the 100-400s become 90-175s, the 120-600mm becomes a 120-180mm and the 150-600s become 100-175s.
