RX-1 owners: Is your aperture circular??
Dec 11, 2012

Someone else started another thread about this, but it was mis-tilted.  The aperture in my RX-1 is not round throughout its range (worst in the middle of hte range range around f/2.8-f/10).  Several other commentors said they saw the same thing in their RX-1s (the same specific blades of the aperture sticking).

If you have an RX-1 can you please look at your aperture blades and report whether yours is prefectly circular or looks like mine?  I am trying to decide if I want to return the camera for a new one or if they all have this problem...

Simply just put the cam in A mode and look down the lens while adjusting aperture. Or, shoot an out of focus point source of light at various apertures and inpsect the photos (works best shooting a distant light source while manually focusing the camera to the minimum focus distance).

Thanks!
