P.J. - I’ll see if I can get two parallel kits together and weigh them for you. A reasonably precise scale will be an issue.
But meanwhile, note that your calculation is off. If you were to use the 645Z and wanted a lens that gave you the FOV of a K-mount 300mm, you would be using the 645 400mm for a FOV of about 320mm. Or you would use the 645 300mm with a 1.4x converter. The 300mm, 400mm, and 1.4x (and 2.0x) are all readily available. I don’t currently have a 645 300mm but IIRC the size/weight of the 645 version were very similar to the K-mount of the same era. (I.e., comparing A-stye to A-style.) stan On Dec 8, 2014, at 2:20 AM, P.J.
