The TTH Cooke Vidital 1.3/30mm lens is handamade lens and this is the first time we see a UK made lens on a Micro Four Thirds camera! As the author says: “You can´t find a second of this lenses in a helix like this, it is nearly unpossible to find a 30mm Vidital. It is a really unique lens.” You can see a set of image samples on Flickr: http://www.flickr.com/photos/cinegon/
That is the tetx posted by the author on eBay: “I made a helicoil by my self, I´am using a brass/alumium combination to make it very solid, this helix allows a focus range between infinity- ~ 12cm. So it is useable as a macro lens too. The helix has no stop position to close focus, so it is possible to use the full lenght of it, for the future it is easy to unscrew it when a cleaning or new lube is needed. The focus ring has six screw sticks for an easy handling, the aperture ring has a large diameter too, believe me, it is perfect for handlig, specially for movie making. The lens is useable with MFT cameras without any dark corners in all modes. The lens has a wonderfull bokeh, better then the Speed Panchros has. The lens is 100% made in England.
The lens were made in a time when TTh and the American lens makers decide to engrave the lenses with the transmitted speed, so it is marked with T1.5 the F speed is F1.3 Later TTH went back to the F stop engraving because the Japanese and German lens makers do it also and a lens with F1.3 is better for selling than one with T1.5.”
