    C-mount lenses for the NEX

    Hi,

    I have just received my C-mount to NEX adapter, along with a 35mm f1.7. I know, itīs not sharp, itīs a bit like a shift and tilt, but I havenīt had so much fun with a lens in ages. Plus the combo lens-adapter is soo smal that makes the NEX5 ultra portable. So Iīm wondering which other c-mount lenses out there are worth getting. I saw a 12.5mm, a 16mm and a 24mm that seemed cool.

    cheers

    Rafa

    Search pictures for this €70 lens :-(

    From Fujian you get better lenses - 35mm/1.7 = $29.88 and 25mm/1.4 = $24.85

    Real dudes buy (used!) 25mm/0.85 for $ 995 (ebay - hohohohoho)

    I had my eyes on the 25mm toy cam but the seller said it doesn't work on the NEX because it doesn't cover the entire sensor.

    Isn't one of the aspects of lomography heavy vignetting, so I don't see the problem

    Re: C-mount lenses for the NEX

    I can handle a bit of that classic vignetting...but I'm guessing this lens is so small you will probably see a massive black circle. I'm currious to see some samples on a NEX camera.

    kjyuan - the 25/1.4 1/2" cctv lens I got from ebay gives pretty much a circular frame, although I've yet to test it with video, where it may give a fuller rectangle.

    The 35/1.7 2/3 cctv c-mounts seem ok for stills, steve huffman (sp?) did a nice blog post about them. If you have a nex to c-mount adapter already, they go for about $40ish on ebay.

    Ampguy, could you post some samples of the 25mm f1.4 with the NEX? I'd like to see how bad is the vignette.

    Re: C-mount lenses for the NEX

    Thanks for the samples. The 25mm with micro 4/3 is really acceptable in my book, but not with the NEX. The black circumference around the image is so big I think people should come up with another name other than vignette. That is unusable to me.

    Re: C-mount lenses for the NEX

    The differences are crop=1.5 (NEX) and crop=2.0 (m4/3) - of course 35mm/1.7 is better ... no vignetting.

    Re: C-mount lenses for the NEX

    right, just a note, the freebie, or low end c-mount adapter from rainbow for nex is a tad thin, it needs a shim to focus right, i notified them, but they have another one (RJ?) at a bit higher price that could be the right thickness.

    Agree, the 25/1.4 cctv is ok on u4/3, but not the nex unless you want the effect or are going to crop in pp.

    Re: C-mount lenses for the NEX

    The crop would have to be way too big to create something usable. it would end up with something way too far from a 25mm.

    Re: C-mount lenses for the NEX

    Hi, very nice photos, were these cropped? I bought a 25/1.4 with nex to c-adapter from camplus on ebay, at a great price, and with great service, but have a lot of black on the edges (similar to the nex with 25/1.4 images posted above in this thread).

    I'm wondering if your lens if perhaps your Fujian 28/1.4 is a 2/3" instead of 1/2" c-mount or something?

    Would you happen to have any links of folks selling this particular lens?

    Thanks!

    Re: C-mount lenses for the NEX

    I am waiting (since 4 weeks) for a (nonvignetting) Fujian 35mm for $ 28.
    Some weeks and it is springtime ... new movies with 35mm :-)
    Now there is only thick fat fog :-(

    4x short videos with NEX5/Fujian28mm - f=1.4 and f=8
    fast and freehand .... temperature = 0.2°C

    http://www.megaupload.com/?d=DHRZCSLM

    less vignetting with m4/3
    no vignetting with Fujian 35mm/1.8

    NEX5 and Fujian 25mm/1.4

    f=1.4


    f=8

    Re: C-mount lenses for the NEX

    Thanks, nice effects. Although the 35/1.7 cctv c-mount lens does seem to vignette less, I think they may have field curvature, although it can still be a nice effect lens.

    Just crop, and then pretend you have a 10MP Sony M 4/3 camera!

    This result is not surprising, most 25mm c-mount on M 4/3 is fine but heavy vignetting. My 12.5mm was usable on M 4/3 in 16:9 mode.

    I think Fujian 35mm/1.7 and Fujian 25mm/1.7 are SAME lenses
    like 3x so expensive "SLR MAGIC" lens 35mm/1.7 and SLR Magic "Toy lens" "26mm"/1.4

    SLR Magic "Toy lens" "26mm (haha!)"/1.4


    Fujian 25mm/1.4

    Yes, they are, the m4/3 folks have been using this for awhile. SLR Magic does the colors, and maybe glues on the C mount adapter on though for the NEX version ($10 value there).

    $300 for a ugly P&S with a useless TINY sensor that would cost $150 max with a fixed zoom lens. It is a novelty, nothing more. The lenses might be interesting, but new, high-quality c-mount lenses are not cheap, they run anywhere from $300 to $6000 (Fuji motorized 25mm f1.4 for 2/3" sensors).

    Re: C-mount lenses for the NEX

    I found another good candidate for NEX- Wollensak 1" (25mm) fixed focus lens-

    http://hokkorihokorin.blog26.fc2.com...entry-168.html

    Those are full-size uncropped images, full coverage with some vignetting that isn't bad (not sure how it will look stopped down.) You basically unscrew the lens to focus, which actually doesn't sound that unreasonable to me.

    Re: C-mount lenses for the NEX

    If anyone's looking for a Fujian 35mm f1.7 lens, Amazon has them from RainbowImaging. Nicely, they are in Amazon's warehouse so free shipping for prime, plus they're shipping from the USA.

    It's a combo deal with the lens and a c-mount adapter for $37:
    http://www.amazon.com/RainbowImaging...8143256&sr=8-1

    Here it is for m43:

    I picked one up, and have been enjoying it immensly!
