I am selling here an Olympus 50mm F1.4. It is the highly sought-after version of this lens as its serial number is over 1100000. This is the last and most desired batch of Olympus 50mm F1.4.

Its cult status originated from Ken Norton, who tested all the Olympus OM lenses. His tests of the multicoated version of this lens showed that those with serial number over 1100000 are the sharpest, followed by those with SN number between 1000000 and 1100000. Those with SN below 1000000 are the least sharp. Please see this link: http://zone-10.com/cmsm/index.php?option=com_content&task=view&id=243&Itemid=1

People suspect that Olympus either changed the optical design for this lens over SN 1100000 or adopted new coating. This lens is very difficult to find due to small production numbers. Many on the internet have WTB ads for this lens.

A Taiwanese tester also used this lens with SN over 1100000 on Canon 5D and he thinks very highly of the lens. See the link: http://shutter-releasing.blogspot.com/2011/05/olympus-om-zuiko-50mm-f14.html

The lens for sale here has perfect optics, with no scratches and fungus. It has both front and rear lens caps.

This lens is the smallest 50mm F1.4 lens and is widely used on Sony A7 and Canon 5D series digital cameras.
