One item might need clarification when you write your detailed eBook. In terms of the 17x7.6mm lens you used, with the 2x extender that would be like a 15-258mm lens. Then when you mount that on the BMCC, with its crop factor of 2.28x, you are looking at the field of view of a 35-589mm lens on a full-frame camera. Steady as she goes!
Hey Rick! Thanks for the feedback! Yeah, I should probably re-word that small part in the blog post. What I was trying to convey was that the 17x7.6mm would give me an effect zoom range that started on the wide end to that of a 16mm Canon EF lens and zoomed out to that of about a 300mm Canon EF lens equivalent. Or in other words, it was like having a Canon 16-300mm lens on there (referenced by swapping and matching with actual EF zoom lenses), figuring this might be easiest for people to understand the relative zoom range against wheat they're used to currently using with still photo lenses. But yeah, after the crop factor calculation is in place, it's more akin to the 35-589 range you speak of. I should probably clarify this in the blog post. Thanks!
