used a new 2x cheapy sigma teleconverter to make the TAMRON SP 150-600mm F/5-6.3 150-600 work at 1200, zoned in on the moon rise between a building and a tree and given it was on a tripod not tracking you can see the colour fringing. but not bad for F12.6, think the iso was 6400 and the TV was 1/200
then i went with my son to see the Kingsmen 2
