  1. <p>Leica's own offer does not work with the 100mm APO. I'm mounting the lens on EOS. So any flat type of tele converter shall work with the 100mm: Kenko, Sigma, Tamron. Any experience?<br>

    And how about such 1.4X with 180/2? Certainly Leica's 1.4X APO should be the best. But the cost is high and I may not use it much (I got 2X already). I saw a post saying Kenko 1.4X works well with 180/2. Any experience?</p>

  2. <p>Though the work I'm doing is on a 35mm lens, I think large format people may have better ideas.<br>

    I've just filed down the rear end of a 28mm Zeiss lens, since the mirror of my Canon DSLR hits it. Now the way of the mirror is cleared, but the rear end reflects lots of light onto the image sensor -- I only had a black marker at hand which is quite glossy. So, I need to paint it black, completely black. Can somebody recommend a good matt black paint?<br>

    If such a paint is not available, maybe I can somehow smoke it?<br>

    Best,</p>

  3. I'm looking for a Leica digital camera to take long exposures at low light. I'm not considering M8 as the future

    of that line is not clear. So, can anyone give suggestions among the point-and-shoot's? I only need to make 10x10

    prints at most.

     

    I plan to crop photos for the most of cases to square format. So 4:3 format is not a problem (or maybe even an

    advantage). The questions in my mind are:

    1. focus accuracy (or how easy to manual focus)

    2. noise: I will be shooting at ISO 400 at most, and making long exposures with tripod. Does noise appear under

    such a condition?

    3. battery life: the exposure time ranges from 10 seconds to hours.

    4. Above all, lens performance with strong light sources in frame.

    5. Bokeh: does such a lens still have good bokeh that characterizes most of Leica lenses?

     

    Thanks!

  4. OK. I just discovered this, and would like to know if this is common, or "by

    design":

     

    I have a set of neutral density LEE filters. They are rectangle, and made by

    resin. I put two pieces together, with the letters facing each other, and it

    clearly shows 1-2mm gap in the middle while the two ends touch each other. So

    the filter is not flat! I purchased the set new about 4 years ago and used them

    only a couple of times. They are always try.

     

    When mounted correctly on the holder, a Lee filter is flat, since it is pressed

    by the holder in the middle. But how "flat" is this? Since I do landscape for

    the most of time, I have never noticed the problem.

     

    Any idea?

  5. I think this is true. I tried to power on/off for several times, each time

    printing a nozzle checking from Test Print menual.

     

    Here is one example:

     

    Printing 6 color blocks

     

    clean

     

    printing a large rectangle block of yellow

     

    clean

     

    printing 6 color blocks

     

    clean

     

    printing a large rectangle block of yellow

     

    Done. Ink consumed: 0.3 ml (Sounds right to me)

     

     

    Power off and on, and run nozzle checking from manual again.

     

    Printing 6 color blocks

     

    clean

     

    printing a large rectangle block of yellow

     

    Done. Ink consumed: 4.9 ml (I just don't believe this figure!)

     

     

     

    To me, Epson probably flushes expensive ink away generously every time the

    printer is powered on, but does not want to let the user know about this -- so

    they somehow count the amount into tasks like cleaning/printing.

  6. I need to use a Satin Snow on a Technkardan that was previously

    equipped with Linhof Super Screen. There was a suggestion that the

    position does not need to be adjusted since the super screen's matt

    side faces the lens. However I am not sure now: I focused the tk45

    with its original back and then with everything locked, replaced the

    super screen with a SS gg. The latter shows an image out of focus. So

    I believe the 4 little screws need to be adjusted. Now the question

    is, by what displacement should they be adjusted? I no longer have a

    super screen.

     

    Thanks!
