    I remember reading recently an article of a 250kg 1700mm f/4 Zeiss lens for Hassleblad.

    So no, that isnt the biggest lens in existence. Its only 220 pounds, ~100kg.

    Where does it say its the biggest lens in existence? is says - The world's largest dedicated SLR Super Telephoto lens.

    I believe the Hubble Space Telescope is the winner for the biggest.

    You are just now discovering this lens??? Geez, we have talked about it around here for years.
    I've reached the age where my brain went from "You probably shouldn't say that" to "What the hell, let's see what happens."

    Well for only having just recently taken a interest in photography a few months ago im not up to what was discussed on this forum 2 years ago and i though it was interesting. Maybe some of the members who were not around 2 years ago might find it interesting also.

    Maybe you are not too active in here. That lens and video was quoted in the past week or 2 ago. But that's ok, we understand since interesting things always pop up here once in awhile. Thanks for the post anyway.

    I understand it's for sale too...or was. I think they were asking $76,000 for it. I'm not sure on that, but I think I remember an article on this lens somewhere that said that.

    The Hubble isn't very big at all, having a 7.9 foot mirror.

    The Hubble's big advantage is it's above Earth's atmosphere.

    The 7.9 foot primary mirror was made by Perkins-Elmer and was shaped wrong such that it had sever spherical aberration.
    A testing device (null corrector) used during mirror figuring to assure a properly shaped non-spherical mirror, had been incorrectly assembled.
    Unfortunately, the error in the primary mirror would not be detected until Hubble was on orbit.

    The Gran Telescopio Canarias single aperture telescope has an effective light gathering surface that is just over 34 feet across (10.4 m, or 410 inches), which is 4.3 times greater than the diameter of Hubble's mirror. Gran Telescopio Canarias - Wikipedia, the free encyclopedia

    The Large Binocular Telescope has 2, 8.4 meter mirrors. Large Binocular Telescope - Wikipedia, the free encyclopedia

    The Keck Observatory's optical telescope interferometer has 2, 10 meter mirrors. W. M. Keck Observatory - Wikipedia, the free encyclopedia

    Photography is at its core an attempt to represent the reality of light in a media that canít faithfully reproduce it.

    If I'm not mistaken, the initial problems with the mirror on Hubble was a failure to convert Metric measurements from the European team to Imperial measurements from the US team. That's why I'm still pissed off with the US promise to go metric back in the 60's. How difficult is base 10?

    You know, I think it is more difficult for not using metric.

    That issue was between NASA and Lockheed. The conversion of newton-seconds to pound-seconds was the f-up, and cause a very expensive Mars probe to dip into the atmosphere of Mars and burn up.
