  1. <p>I have the LT version of this mount, and I am very happy with it. The screws with retain the mount are not Phillips head screws, but JIS (Japanese Industrial Standard) screws. Phillips head screwdrivers will tend to cam out, and with the sensor exposed, that could be disastrous. A set of JIS screwdrivers can be readily obtained from Amazon.</p>
  2. I have one of these (3rd gen) in black. It is an absolutely superb lens, and a great pleasure to use. The focus ring is scalloped nicely, and rotates smoothly, without binding. The images it produces are sharp and contrasty.

     

    I've found this lens, especially in tandem with the sizeable viewfinder it is paired with, tends to get people's attention. I guess it appears out of proportion to the small bodies it gets mounted on.

  3. 1) "To get on with it." -<i>John Richard Massey</i><p> Here here.<p>

    2) Getting some of my work displayed publicly. A coffee shop in my neighborhood wants to show some of my pics. The prospect really has me wired, and it's not just the coffee. :)<p>

    3) Lose (a substantial amount of) weight. What's the point in carrying some of the lightest and most compact photographic gear ever made, while simultaneously toting a spare tire; in my case, a spare tractor tire.<p>

    4) Stop obsessing about equipment...<p>

  4. The most convincing argument I've seen for the Hexar RF's purported point-of-focus problem is loose tolerances for manufacture of the bodies. My findings with regards to lens flange to film plane distance is including the the previously mentioned article by Dante Stella. My Hexar RF's and M6's film to flange distances are within 0.01mm of each other, so I'm apparently fortunate to have a Hexar RF built to Leica spec in that dimension. I use M-Hexanon lenses on my RF, M6, and M3, and don't perceive any focusing problems. I also use Leica and CV lenses on my RF, again with no apparent focusing error.

     

    How do your M-Hexanon lenses perform on Leica bodies? Are their true points of focus equal to what is indicated in the rangefinder and on their focusing scales? If so, it is certainly a quandry, as the flange depth for which the M-Hexanon lenses are designed can't spontaniously change when mounted on a Leica or CV body.

     

    Also, it seems to me that if flange distance is the root cause of the problem you are observing, the focusing depth error would change, depending on lens focal length. The wider angle the lens, the more critical is the accuracy of the flange distance, and the greater effect error in same will have on shifting point of focus.
