Has quite a long focus through that helps for finer adjustments, but if you're aiming overhead, the focus may slide. I use rubber bands to solve that problem. Using straight luminence at f2.5, you will blow out the background sky at 180s. Even shorter for a monochrome cam. So you bang out heaps of short (90s) subs. The lens is so dangerously sharp that it tears a 20mp bayer senser to shreads - even with the AA filter in front of the bayer colour filter array. It would resolve 100mp+ if those pixels were available It would find a good mate with a good monochrome sensor if there's room for the filter wheel!
Great stuff Troy, cheers for the info ...Zeiss huh? hmmm?

Oh and I'll take that PL16803 off of your hands if you're not planning on using it any time soon Mike
He he, yeah bet you would Colin ...might be good to swap out the 16803 sensor for a KAF-50100 actually.. 6 micorn pixels hmm?
