    A rangefinder lens, because of it simplicity, will also have less glass elements hence less glass surfaces than a SLR lens. This can give better contrast. Lenses with less elements are simpler to make, simpler in construction so may be far more rugged than a given SLR lens.

    As for precision in focus; In low light, I must say that it is easier to focus my Leica M with its 35mm lens than my Nikon F3 with it's 35mm lens.

    Some people enjoy using RF cameras because it feels right to them.
    Some people prefer apple pie to blueberry pie. Same diff.

    Here's a thought experiment: Use a 10 second exposure and move the camera up and down? Will the dot be blurred? Of course; it will be a line. Now explain why the physics of motion are different for 10 seconds vs. 1/10th of a second.

    Yes, the dot moves with the camera. That's the point. However the background doesn't move and the path the dot traces on the background will be recorded.

    Heh, heh, heh. Think about it more carefully.

    The point of the test should be to see how a moving camera records a static object in a real world situation...not to see how a moving camera records the movement of an object that is moving just as much as the camera. Photographing the laser attached to the camera will tell you how much the camera moves, but photographing a still object will tell you how a still object will actually be rendered. The first is simply informative. The second gives you actual practical knowledge. For instance, not just how much does the camera move, but how much movement is acceptable in a picture that is shot in a real-world situation.

    Really. This is test is terribly over engineered. Why can't you just shoot the front page of the Times tacked to a bulletin board? Shooting a laser is just a techy way to make some piece of modern technology seem more useful than it really is.

    ...besides, we all know that the ONLY real use for a laser pointer is for playing with cats.

    That's about the best use I can think of for one.

    Maybe because the techie geeks among us are more likely to have a laser pointer than any page of the Times?
    Besides, everyone knows a test using technology is far superior to those that don't.:rolleyes:

    Yup...and we don't even have to get off of our fat asses to do it! Even better!

    Call me a Luddite, but I buy the paper every week day. $16 per month to support analog circulation (and the local American jobs that go with it) in my local newspaper machines is worth it to me. I get way more information than I would online, in less time. I also get the funnies, the crossword, sudoku, and one of my personal favorites, the obits. Plus I get to take a walk to the machine from work and back. I also don't bug my eyes out or have to sit on my butt to do it. I feel I am lucky to work in a place without a computer or ass sitting on being a necessary part of my job, personally.

    (Any sheet of paper with text on it will do, of course.)

    No, it will not be blurred, unless the laser pointer is poorly attached and moves in relation to the camera. Laser pointers do not leave trails on the wall; it just looks like they do. Why don't you try it some time and report back.
    f/22 and be there.
