fred 76: This SLR is of no use in astro-photography :
Remote Capture is impossible with it !
That's crazy for such an expensive camera.
tjbates: It's funny to me that one of the main critisisms of Canon was that they didn't have auto focus lenses optimized for video. The thing is that anyone who has a clue about focussing for video with a DSLR doesn't use auto focus even if it is available.Now we have a lens that apparently can't easily be manually focussed. OOoopps.Which market is this for?
I don't own a jib but I'd imagine you're almost always at infinity if you're using one. But if you did need to focus I suppose you'd do it the same way as with any other video camera - a monitor and a remote.
