Cleaning out down-stairs I came across this massive zoom lens I acquired some 15 or 20 years ago salvaged from a TV Studio camera. It's big, weighs 2-3 kg and zooms from 15 to 150mm with F2 fully open throughout the zoom range.
Anyone have any thoughts on whether this could be good for astro-work?
It's covered in dust, but I'll clean it up and try and work-out where the focal plane should be ... it looks like with a bit of though I could adapt my spare Canon EOS adaptor onto the end but suspect I'd need an extension tube to get focus with the dslr... I don't know how big the film was that this projected onto so not sure how cropped or whatever it would be
Still worth a look I think. It's got an over 4 inch objective and if it ran at 150mm and F2 it might do some good stuff. If it really does 15mm it would be wider than my currenty wide-angle. Could look a bit "excessive" though carrying it round with my Canon 40d tacked on one end doing landscape pics
