  • I see. Well I already picked up the Voigt 17.5mm and sold my Panasonic Leica 25mm 1.4, but I find myself still trying to convince myself to get the BMCC-MFT instead of the pocket. Logic and $ says pocket, since I'll be exporting for the web, but there's something about the BMCC that keeps me interested. Maybe its just the more professional looking body and the hope of 2.5k raw downscaled being more crisp. Either way, one of those cams will be mine this summer.

  • A full frame 50mm f2.8 will probably be sharper than if you use the Voigt at f0.95 I am guessing as they are not maximized at widest. The SLR 25mm might do well if you can get past the CA. BMCC moire or loss of depth with CA with the Pocket Camera - these seem to be the choices.

    The Voigtländer 17.5mm f0.95 should give you about the same look as a 50mm f2.8 on a full frame camera like the 5D. Of course it won't be razor thin, but it should be pretty decent. The only problem with the Voigtländer I see is that it costs more than the Pocket Camera.

  • @killagram All I can say is -- Wow! Of course there are IS issues, and objects moving too close to the camera, but this really shows what is possible... Thanks for the link.

  • @TGDude

    You're right about using faster lenses the DoF will be shallower, but with wide lenses the effect is reduced, so you would have to use longer focal lenghts to achieve the same DoF. For example, i use a 85mm 1.2 with my GX1 with great results!

  • There's been a lot of talk about the DOF not being shallow enough on a S16 size sensor. Since the crop forces you to step back farther when framing the shot, causing an increased DOF, wouldn't using faster glass, wider open (Voigtlander 17.5mm F 0.95) solve this problem or am I missing something?

    I love the shallow DOF look, so if it actually became an issue w/ the pocket, I would prob go w/ BMCC-MFT, but I don't see how that would be an issue at F 0.95 - F 2.0. Correct me if I'm wrong since you guys are more experienced.

  • @danyyyel The Cosmicar (is from Pentax!) 12,5mm Silver Version does not vignette, has absolutely no distorsion and is Tak-sharp at f2.8, so under BMCPocket it will get a 36mm lens; So i think it is a real alternative to the Tokina 11-16mm.... If you consider to buy a Tokina, it will cost you ca. 600 Euro.....

  • I also wanted grab some lenses before the rush but after research for some days I decided to wait. All quality lenses sold on ebay are quite expensive. I had some Zeiss S16 PL lenses on the list and all were sold at starting at 1.000,- € and you still need an adapter for that. I am very sure that we will see wide angle lenses quite soon and that we dont have to struggle with CCTV or vignetting lenses that dont match really.

  • where do you get those lenses? I almost never find any lens on ebay that is mentioned here.

    Where do you search for them?

    (I live in Germany so maybe won't apply to me, but still i am interested!)

  • @Brian202020 Yes that is why I don't understand the frenzy of those C mount lenses. The Tokina is a know quantity in terms of sharpness and distortion and will be usable on larger sensor camera. So it is a much better investment for the future. The only thing I hope is that metabones or mikanon does provide an iris control for the M43 to Nikon mount version. We should tell Vitaliy to contact Mikanon.

  • @Hakosuka Actually, because of the multi-aspect sensor in the GH2, that doesn't really play out in the normal video modes (where the GH2 is noticeably wider than a 2X crop, many say more like 1.86x but I won't bet money one way or the other :).

    If that were true, then 1.86x20 = 37.2 while 3.00x14 = 42. However the GH3 is much closer to an actual 2x crop, so 2X20 = 40.

    42/37.2 = 1.129 42/40 = 1.050

    So the GH3 comparison would be more accurate, possibly by around 7% (but I don't know how accurate 1.86 vs 1.88 is for the crop factor, etc.)

    Not sure if that helps but figured it was worth a shot. :)

  • Don't forget the http://panasonic.net/avc/lumix/optional_accessories/dmw_gwc1/

    Turns your 14mm f2.5 into 11mm. Not a lot of new ones left out there but you can still find a few.

  • Yep, I'm getting m43 speedbooster for my 11-16, once it's available :) Sorted!

  • @danyyyel

    I've been talking about it. I've mentioned it several times. The Tokina 11-16 f2.8 effectively becomes a 8-11.5 f2 when a Speed Booster is used.

  • Is there a reason why people don't talk about the Tokina 11-16 and a speed booster/mikanon adapter.

  • Cosmicar 6,5mm f1.8 will cover the S16 Sensor.

  • this test does not include testing of coverage of a super 16 sensor (or any sensor, as far as i could see) - did I miss something there?

  • The nice thing about cctv lenses is that they are cheap cheap cheap. It's important to note barrel distortion, but that is often a desired look. There's no 'wrong' way to shoot anything, provided that it's your intent to shoot it that way

    A great test of super wide c-mount lenses; cant speak Thai but i think the pictures speak forthemself.

  • To all the folks excited about c-mount lenses: ultra-wide CCTV lenses tend to have awful barrel distortion. I tried a whole bunch when I was looking at getting a Pentax Q. I couldn't find anything in the sub-10mm range that didn't give a look like GoPro. If that's what you're looking for, great. But I was unable to find anything that was wide and not fishy.

    Also, many have odd irises with three or two (square) leaves. Wide open, this isn't an issue. Stopped down it made for weird bokeh. Also know that most of the zooms are not parfocal. In fact, they're so not parfocal, that if there's a term for the opposite of parfocal, they're exactly that.

    This is not to discourage anyone--by all means, check them out and let us know all about them! But know the possible limitations before you buy.

    My experience with the Computar lenses was: solid build, too much distortion. Similar issues on some of the Fuji ones too. Can't remember specific models, but everything I looked has was f2 or faster.

    Lenses like Angenieux are geared toward film makers, so they tend to have less distortion, be easier to use live. But they probably don't go as wide as some of the CCTV targeted lenses.

    I'd LOVE to see a database assembled with distortion characteristics for all the C-mount lenses.

  • eyeiaye: I have a 12.5mm and 25mm cosmicar f1.9 and i highly recommend the f1.9s.. they are well built and give a decent image. I took one apart completely and it has a 10 leaf shutter, with brass/alum mechanics throughout. Very well built lens

  • Must say that sample footage looks very very nice! Cant wait to see what the camera looks like with some other known lenses, like the 25mm f1.4 summilux, the 14mm 2.5 and the SLR Magic f.95 etc.. I'd like to see how much shallow DOF we can squeeze out of this thing given the sensor size. I can get way more shallow than I like on the GH2 this may be a perfect match for my taste.

    I personally think the other industry player,s have lots of catch up to do now.
