John,

Thank you for your reply.

Hello,

Can anyone tell me if they experience the shutter tripping when using the depth of field preview on their 645D?
I am using the Optical Preview through the viewfinder, which is the default setting. I am not using the Digital Preview. When i release the main on/off preview switch, to return to normal camera operation, the shutter sounds and appears through the viewfinder to have fired, but no image appears on the screen.

Also, has anyone experienced any issues with the focusing ring of their 55mm kit lens? If I place my thumb and index finger either side of the focus ring and gently move it from side to side there is movement in each direction of around 1mm before the ring starts to alter the focus. When the lens is taken to the stops in either direction the focus ring continues to rotate indefinitely.

Can anyone tell me if either of these concerns are inherent features of this camera?

All possible explanations gladly received.

Chris

Ken,

Thank you for your reply. In my excitement to start using the camera I did not notice the characteristics of the lens, so I assume they were already there.

Hello,

I have a 645D with standard 55mm kit lens. The camera has around 500 actuations.

I am concerned by the loose and imprecise movement of the focusing ring. If I place my thumb and index finger either side of the focus ring and gently move it from side to side there is movement in each direction of around 1mm before the ring starts to alter the focus. When the lens is taken to the stops in either direction the focus ring continues to rotate indefinitely

I am familiar with my Pentax 67ii lenses which have precise movement and focus rings that cease to rotate at the stops.

Have any Pentax 645D owners experienced the same characteristics with their 55mm lens? Are these traits a result of modern manufacturing methods or do I have a cause for complaint?

Incidentally, if anyone out there has a 'as new' Pentax 67 to 645 lens adapter for sale, I would be very interested to hear from them.
