M28x0.5 male to RMS female thread adapter

• Front side - RMS/DIN (0.8″-36tpi) female thread
• Rear side - M28x0.5 male thread
• Distance between flanges - 0 mm
• Weight - 7 g

This adapter allows you using easily available RMS/DIN microscope objectives on some enlarger lenses and pocket digital cameras that have M28x0.5 filter thread. Such setup can be used for macrophotography purposes.

This adapter preserves parfocal height of an ovjective since both M28 and RMS flange planes are mached. This implies one limitation - rear part of RMS objective should have diameter not larger that 24.5mm. Most LOMO objectives fit this size.

Machined from anodized aluminium.
