    Introducing... THE DENIZ SHUTTER

    I'll keep the story short.. I needed a shutter for my new 210mm lens and didnt have the $500 to spend for a SKgrimes mounting job so i made my own studio shutter. the accuracy depends on my reflexes.. but so far i am pleased with it ths is the first prototypelater versions maybe a little sleeker looking.

    it accepts upto 77mm filter on the front. It doesnt vignette with the 210mm lens, and acts as a lens shade in bright sun!!

    I may custom build one for anyone that needs one.
    Its made out of maple and basswood so its not heavy but plenty strong

    in the photos its mounted on a sinar/horseman board on my 8x10 tachihara

    That's very interesting. You're able to move the "slide" up and down without shaking the camera?

    the darkslide is made of 1mm thick black anodized aluminum.. its it smooth and slides between 2 black dense foam pieces that act as the light trap. darkslide doesnt reall touch anything else..there is enough friction to take your hand off of it when its open but its smooth enough that you can puch it down with no camera shake..

    Interesting Deniz, but I'll stick with my lens sock shutters.

    here is a little ipdate on the project..

    I did a slight modification to the shutter, removed one of the 2 foam pieces and glued it on the aluminum darkslide.. this way darkslide is not self supporting when open but closes down automatically when i let go of it(i can clip on a clothespin on it wen open for selfsupportiveness)
    .. so there is no camera shake whatsoever!!!

    I am going to Tofino,BC(look it up a must go place for every human being) in the next couple of days and aking my 8x10 along.. i sure will put this lens to a good test there...

    cheers

    Looks very effective Deniz.
    Pls pardon my ignorance but: why is it the ULFer's have this need for home-made shutters? Is it purely the cost aspect?
    And how do you get around exposure accuracy issues?

    Just curious because I'm planning on growing into a real grown up camera one day.

    John,
    We use dark slides, Bowler Hats, Caps, Lens Socks (my personal favorite), DENIZ Shutters and Packard shutters because we have barrel mounted lenses which have no built-in shutter - just an iris. Sometimes they don't even have an iris. Mounting such a lens in a shutter - especially if it is a large lens - becomes very expensive.

    At small apertures (f32 and smaller) the exposure times are long. Exposure timing errors (of a second or so) become insignificant with exposure times in the 10's of seconds.

    Lens Sock/Shutter in place on 455mm Apo-Nikkor

    Pictures taken with this combination are very sharp - no camera movement.
