<ul> <li>Front side - RMS/DIN (0.8″-36tpi) female thread</li> <li>Rear side - M28x0.5 male thread</li> <li>Distance between flanges - 0 mm</li> <li>Weight - 7 g</li> </ul> <p>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.</p> <p>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.</p> <p>Made of anodized aluminium.</p> <p> </p>
