Description
| Alpa flat lens boards are 88.5mm square (3.48”) with a 2mm thick lip. The rear of the board features a raised light trap and the overall thickness is approximately 2.9mm. Unless the lens is being used in a fixed focus application, a focusing mount is required to use a lens with this board on an Alpa camera. The S.K.Grimes versions are machined from 6061 aluminum, glass beaded for a matte appearance and given a black anodized finish. S.K.Grimes manufactured boards may have slight dimensional and profile differences from the original equipment manufacturer |
