It's not distortion of the lens type, it's an effect of the focal plane shutter working in slit mode. As the slit crosses the frame, the wheel moves forward, giving the oval shape. It's just fortuitous (or maybe a result of this photo in particular) that the direction it leans is the one usually depicted graphically to indicate speed. > > > > -----Original Message----- > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > > Behalf Of [EMAIL PROTECTED] > > Sent: 21 May 2007 22:39 > > To: Pentax-Discuss Mail List > > Subject: OT: Need help with my homework again > > > > The list rocks!
