The reducer / corrector reduces the focal length, increases the light intensity and corrects the field.

The reducer is designed for sensors up to full format. In contrast to the Riccardi Reducer, this reducer does not require an extreme back focus. It can be used on all refractors that are designed for 2 "and have an eyepiece extension from 2.5".

Distance T2 thread to the camera sensor. The distance depends on the focal length of the refractor:

• Focal length up to 350mm: 70 mm
• Focal length up to 420mm: 65mm
• Focal length 450-500mm: 61mm
• Focal length 510-600mm: 58mm
• Focal length 610-700mm: 57mm
• Focal length 710-790mm: 56mm
• Focal length from 800mm: 55mm

The reducer is designed for all refractors that are designed for 2 "accessories. It provides a fully corrected and illuminated image field up to 45mm - ideal for DSLRs up to full format!

The corrector is a further development of the well-known RICCARDI REDUCER. The 4-element design offers very good correction performance in the field, which cannot be achieved with the simple 0.8-fold reducers.

In contrast to the Riccardi correctors, this corrector can be used on any refractor with a 2 "focuser. If you can use a 2" zenith mirror, you will also have no problems with focusing with the PHOTOLINE Reducer.
