I'm selling a 360precision Absolute MKII panorama head, currently set up for a canon 5d mkII + 17-40mm L.
If you know your panorama heads then you'll know that this thing is built like tank and will give you perfectly repeatable panoramas time after time. I bought it back in 2010 for a project that never materialised, I've made maybe 5/6 panoramas with it. The workflow with the absolute is super easy since it is so perfectly repeatable: you can make one panorama, create a profile in your stitching software (PTgui for example) and never need to align images again: just apply the profile every time.
The head is currently set up for a canon 5d MKII with 17-40mm lens, this combination will give you amazingly high-res panoramas, but you can also order a new deteng rign and arm from 360precision to use another camera/lens combination.
Price is 400E OBO.
