    Not every C-mount video lens is crap [Tevidon inside]

    There was recently some debate here about whether C-mount video lenses can deliver good results on M-4/3rds cameras. I have a few of them that are at least as good as cine lenses (the Pentax 25/1.4 comes to mind), but I recently acquired the crème de la crème of all video lenses: a series of Zeiss Tevidon lenses comprising the 35/1.9, the 50/1.8, 75/2.8 and 100/2.8. All of them are outstanding lenses, providing a sharp image, even wide open, without vignetting and chromatic aberrations and with superb colors.

    Here are some samples from the 100/2.8:





    100% crop from previous image, note the water droplets in bright sun against a dark backgroud without a trace of purple fringing:



    Wide open at F/2.8:



    100% crop:



    And now, the 35/1.9 lens:





    Wide open at F/1.9:





    Not too shabby, uh?

    Cheers!

    Very nice shots, great warm colour.
    There is no question some CCTV and video lenses are very good. Of the 20 or so I've tried (including Schneider's Xenon 25mm f0.95, their 50mm f2.0, Pentax, Sony, Tevidon, etc) the best one I've used is the Fujinon 25mm f1.4, if resolution and neutral colour is your goal. The zooms have been less good, probably not nearly as good as current zooms, especially with in-camera corrections available. But the primes are better than many still camera lenses. Part of the reason is that some of the CCTV lenses must reach a certain resolution because of the markets (scientific, industrial) they are sold into. If you look at CCTV lenses in scientific catalogs, they often spec the resolving power.

    Well Sebastien, I'm very happy that your excellent photos have proven what I have been promising! I'm glad that you're happy!! I have been using Tevidons since many years know (starting as macro lenses due to their short register), but now on mft cameras, they can really shine!

    Debates are what they are for. There are users and debaters.

    Thanks guys for the kind words and a particular thanks to Klaus for those nice lenses.

    Here are some more pictures but this time, from the two others lenses. First, the 50/1.8:













    Then, the 75/2.8:

    Is this the fujinon you are referring to: http://www.pyramidimaging.com/specs/...5HA35HA-1.pdf?

    I really don't want to deal with vignetting, does your fujinon vignette?

    Has anyone tried the Navitar lenses - they sell a large range including some f 0.95 lenses for 1" sensors?

    This Pentax/Cosmicar seems to be the bargain of the bunch

    Any experience with these would be great to hear about.

    That lens seems to be the one madmaxmedia started a thread on, called
    Pentax 25mm f/1.4 C-mount seems to be very popular lately...

    No. Mine is older. Second from the left.

    To a degree, but gone by around f5.6 or longer.

    amazing! Never used that one fro macro, but the close focusing ability of the 35mm obviously allows for that!

    Cine lens sucks? This a Taylor Hobson Super Comat 25mm f/1.9 on the GF1.

    Nice round balls at f/1.9


    Crazy Monet at f/2.8


    Barfing swirlys at f/5.6


    I love cine lens! Selling out the pancake this week.

    Nice pictures. I love these TTH lenses. No one said cine lenses sucked, this thread was just a reply to someone saying that he had never seen a good video lens!
