william_hahn1 Posted April 24, 2002 Share Posted April 24, 2002 Fellow Pentax 67 users, <p> When doing closed-down metering with extension tubesI find that I'm paranoid about changing the apertureof the lens with the Depth of field preview enabled. <p> My question is: does changing the aperture of the lenswith the depth-of-field preview enabled damage the lensin any way? Or is my reluctance just another in a long list of irrational fears? <p> Thanks, <p> Bill Hahn Link to comment Share on other sites More sharing options...
gert_jan_bollen Posted April 25, 2002 Share Posted April 25, 2002 Hi Bill, <p> There is no technical reason why this would damage the lens in any way! <p> Do not worry too much about technical stuff it is designed to be a tool for photography! and not the otherway around <p> Kind regards Gert Jan Link to comment Share on other sites More sharing options...
bobby mahaffey Posted April 25, 2002 Share Posted April 25, 2002 Bill, I've done this many, many times with every lens I use both on and off the camera. It has been completely safe. <p> Bob Link to comment Share on other sites More sharing options...
