    Good article! There's a lot of misunderstanding on this by some people, and some fanboyism as well just like its writer mentions. I for one love to be able to shoot at wider apertures and letting in much more light without having to worry about impossible focus (thus shooting with most films regular aperture of f/5.6 or f/4 but with higher sensitivity!). Full frame for video is pointless to me (with the exception of better high ISO noise handling). There's a very didactic video as well explaining how F stops work and are calculated for those who still have some doubts: http://www.youtube.com/watch?v=KmNIouLByJQ

    And I understood that. I just think the way it's phrased could lead to misinterpretation, it's may not be very clear to some. But it's alright!
  3. Ernesto Mantaras
          Still I think it's kind of misleading. I've read many times over how people actually mean to say that f/2.8 on Micro Four Thirds is equivalent to full frame f/5.6 in light gathering terms, which is absolutely wrong. I say do not feed those "arguments". I agree full frame has an advantage on how good the noise performance is in higher ISOs but that's an entire different matter that even has to do more with each particular camera or sensor rather that full frame as a whole and that isn't clear in the article.

    Here's an official link: http://www.blackmagicdesign.com/support/detail/faqs?sid=27541&pid=27542&os=win I bought a Kingston Hyper-X which is supposedly compatible but haven't tested it yet. I bought it for about $200 but it's around $185 now!

      What Julian mentioned is exactly the GH2, GH3 and/or G6 with crop mode enabled (ETC or EX TELE mode) which allows to use 2/3" lenses, for instance. So it's a viable option.
  6. Ernesto Mantaras
    Well that's because of the protrusion of the outer lens, isn't it? Could there be some other way for it to have a filter thread or some alternative solution?
  7. Ernesto Mantaras
      Indeed! I was blown away by it as well a year ago and changed my mind about buying a Canon at the last minute. Was the best decision I could've made.

    Hi guys! I just wanted to give the heads up in case there's anyone interested in this (and I believe there is, considering how big the GH2 user base is here at EOSHD, the site that got me started!)   Here's the link: vimeo.com/ondemand/3737   At $2.99 it's very affordable, I think you should all give it a chance. I've already bought it but haven't watched it yet. "Musgo", in case you happen to be one of those who don't know, is a Spanish feature film shot entirely on the Panasonic GH2 with an early 44Mbps hack and three lenses (Tokina 11-16mm, Nikkor 28mm f2.8 and Nikkor 50mm f1.4 if I remember correctly) over the course of one week. It has awesome cinematography.   Gami Orbegoso (director, cameraman, editor, color timer, etc.) is very kind in sharing all the gear he used and other info on the shoot. There are a couple of behind the scenes that can be seen here, with several answers to many possible questions you might have on the making of the movie: https://vimeo.com/33456753 https://vimeo.com/57277710

    As you can see in the video, yes. And although it's less than I expected, it makes it useless for using it as an onboard monitor alternative. Perhaps for remote control on live shows or using the G6 as a crash cam, or maybe for the director.
  10. Ernesto Mantaras
      In that regard I'm thinking of getting the Nikon mount Sigma and using the Nikon Speed Booster which has an aperture ring. I like to change aperture that way anyways. It's a good alternative. Now, I wonder if there are any issues related with using the aperture ring on this particular adapter or in any adapter of this kind (with integrated aperture ring). Does any of you know?
  11. Ernesto Mantaras
      No post stabilization (warp or any kind that's actually available to us, at least that I'm aware of) will give you better results than what you can get from true optical image stabilization.   Motion blur, parallax and specially rolling shutter artifacts will always tell on you.
  12. Ernesto Mantaras
    Andrew, why do you promote the 1080p60 from the G6? From what I've seen it doesn't have the quality of 1080p24, it doesn't live up to the G6/GH2 resolution standards. It looks more like the 720p from the GH2, don't you think? I believe that's the mode (1080p50/60) in which those first tests were shot, leading to that fear of the G6 not being as good as the GH2. Here's a comparison that puts it quite clear, courtesy of kgerster: http://www.eoshd.com/comments/topic/3116-panasonic-g6-review-the-gh2-redux/page-2#entry39094
  13. Ernesto Mantaras
    +1 Great editing and you captured nice moments. The music was intense too. You should upgrade the video to 1080p!

    Hi guys! I wanted to share with you this showreel I recently made for my production company and its site which I recently launched: http://www.tordostudio.com   -   https://www.facebook.com/TordoStudio   https://vimeo.com/70074349     Please tell me what you think of it! Cheers!

    Hey, man, that's a real bummer! Specially to work on anamorphic... -.-
  16. Ernesto Mantaras
      Hey! Could you tell me what adapter you used or what process you applied to the lens to make it focus properly (although you mention no machining was needed). Because I have the same lens and used a Fotga adapter I've got for my GH2 and I can' get close focus when on wide. Could the lens be faulty?
  17. Ernesto Mantaras
    Hi! I've just today received two adapters from Fotga to use my Schneider Kreuznach Variogon 18-90mm f/2 and my Tokina 28-70mm f/2.6-2.8 on my GH2 (the former I bought it for the BMPC) and both of them have no close focus when in wide focal length. But when I zoom I'm able to focus much closer. Both of them seem to not be parfocal at this point (I understand both of them are). I guess the problem is a special flange distance needed for each lens that these adapters haven't accurately met. Do you know how I can fix this? Perhaps the Variogon has a back focus adjustment, but what about the Tokina? Could it be broken? These are the adapters I bought:   C-mount to MFT (although now that I see the photo doesn't correspond to the adapter I got; both are Fotga but mine is flatter): http://www.ebay.com/itm/280782331160?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649   Nikon G to MFT: http://www.ebay.com/itm/280662055439?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 I can't now, but I'll upload a couple of videos showing what I mean as soon as I can. Thanks in advance to anyone who can hint me to any solutions!

      Indeed! It opens up a looot of possibilities. Before this sigma came out the Tamron 17-50mm f2.8 was an interesting option becoming around a 12-35mm f2! That's one stop brighter than the Panasonic equivalent (on Speed Booster realm)! The bad thing is you lose IS, unless the EF version supports this feature But bear in mind that, according to what I've read, it's non-Canon (the brand, not the mount) APS-C lenses which can be used with the Speed Booster, because of the connectors and/or a protrusion that Canon APS-C lenses have.
  19. Ernesto Mantaras
      Are you sure? We're talking about APS-C on MFT, not APS-C on APS-C. It'd be great if someone makes a test. But this use of the Sigma on MFT cameras has been talked about for a long time.
  20. Ernesto Mantaras
    I think it's great that it has an aperture ring. It'll be the perfect match for my soon available Sigma 18-35mm f1.8 Nikon mount zoom lens! =D http://www.amazon.com/Sigma-210306-18-35mm-Nikon-APS-C/dp/B00DBL09FG (here's to hoping nothing's wrong with using this particular APS-C lens on the GH2 and other MFT cameras...)
  21. Ernesto Mantaras
      At least if you're planning on getting cheap C-mount lenses I think it's not looking very promising. By the way, the guys from Germany sent me the Schneider Kreuznach Variogon 18-90mm f2 zoom now, but Tungee already showed it works perfectly!
  22. Ernesto Mantaras
    By the way, does anybody know where to get PL mount to Micro Four Thirds adapters? I believe they're more of a niche product than a mass produced one, but I don't know where to look for.
  23. Ernesto Mantaras
    If I had that money to buy lenses I'd probably get the Optar Illumina T1.3 ones. They're designed for Super16 and are faster, plus they have gears. Don't know if they're better or worse optically, but they're probably more organic. Here's a test (with very bad processing even though it's at 1080p and some bad camera work) that I found at Reduser.net. There aren't many sample out there: https://www.youtube.com/watch?v=a-e_3BSg4uM
  24. Ernesto Mantaras
      Fair enough. I'm not putting down RAW, I love the possibilities, and of course I don't expect HDR paint-like images just because you can. I simply expected more detail in the highlights on the skinned girl shots which are backlit but, on a second look, contrast was the way the filmmakers chose. But NOISE was the big problem to me. There was a lot, it was distracting and very unpleasing when those strong patterns showed up. I don't think that was an aesthetic choice. I've only once worked with the 5D MkIII on a full short film (albeit a very simple one) and was underwhelmed by its ISO performance, but I thought it was due to my not diving deeper into the settings (the owner didn't use it for video so it wasn't optimized for it). Now if this video is an example of what it can do at and under 5000ISO it's not very good (and I come from the GH2!). Perhaps it was higher? Also, a little denoising wouldn't have hurt, don't you think?
  25. Ernesto Mantaras
      I agree, Andrew, but to me there were still two problems with the image: the highlights (granted, it was more noticeable in the backlit shots, but felt far from what I've come to expect from RAW) and the noise (there were even harsh patterns like the one in the last shot; I thought the 5DMk III was better in that regard!), Both of these issues made me think I could've easily achieve this without the need of RAW. Of course you can neglect the improvement in detail and color, and the flexibility in post, but I didn't feel this short showcased any of RAW's advantages apart from that chroma keying thing.
