...what would you force him to build before you released him back into the wild? <p> Personally, I hate the AF-assist "strobe light" on my Elan 7. I don't do or desire to do much flash work anyway, so I'd love it if I could get a little hotshoe unit with just a near-infrared AF assister-- no main flash at all. <p> ...And while I'm dreaming, I'd make the engineer incorporate a bubble level into the back of the unit, so I don't have to swap back and forth between the two. <p> Any other suggestions for custom/specialty equipment you'd buy if it existed?
