This image of a Canon 135mm f/1.8L IS lens was posted to Chinese forum Xitek. Most people seem to agree that it's a Photoshop job, since the details on the rim of the lens don't follow the curve of the lens very well. The question is therefore whether the image is some kind of early-stage mockup of a real lens, or simply a big fat hoax.
Fujifilm is set to release an interchangeable lens mirrorless camera -- likely styled like the X100 and X10 -- in February 2012, and details about the camera are already starting to leak onto the Internet. Six photos that appear to show the upcoming camera were leaked on Chinese forum Xitek, but were quickly taken down. PhotoRumors writes that the new camera will be called the Fuji LX and will pack an APS-C sensor.
This photo that allegedly shows the mount and sensor on Nikon's upcoming mirrorless camera was just leaked onto the Chinese forum Xitek. My initial reaction was, "wow, that sensor looks small!". However, the camera is in fact rumored to have a relatively small 2.6x crop sensor (by comparison, the new Pentax Q has a 5.7x crop sensor).
