DA 12-24 on film"},"content":{"rendered":"<p>The Pentax DA series of lenses are designed with an image circle that covers the APSC sized digital sensor.\u00a0 They are not intended to be used on a 35mm film camera, as they create large amounts of vignetting.\u00a0 That almost sounds like a challenge to me.\u00a0 I mounted my DA 12-24 on a PZ1p loaded with Kodak Ektar and experimented.\u00a0 It is immediately apparent that the wide end between 12 and 18 millimeters is out as the lens just doesn&#8217;t come close to covering the film frame.\u00a0 You can see this immediately in the viewfinder.\u00a0 However between 18 and 24mm and with the lens adequately stopped down to about f11 you can actually use this lens as an ultra wide zoom\u00a0on film.\u00a0\u00a0Converting the image size factor around from 35mm to APSC means the 18mm on 35mm film is about equivalent to 12mm on APSC.<\/p>\n<p><span class=\"frame-outer  aligncenter size-full
