  1. Minolta's are much cheaper in general, because they don't fit on dslr's so they are less popular than the Nikkors (that will fit on nikon and canon dslr's). I have a lot of them, picked them up for peanuts.

     

    Advantage of Nikkors is that you can use them in combination with a speed booster on a G6. So if you are thinking about getting a speedbooster Nikon would be a better choice.


  2. So I’ve invested in three Cooke Panchro / i PL lenses which I plan to use via PL adapters to E-mount and Micro Four Thirds in my own filmmaking, especially for an as-yet to be revealed 4K camera I plan to shoot with in Asia in the coming months.

    Cool :) So you teamed up with either Sony or Panasonic... Curious :)

     

    I saw the Cooke lenses on your Facebook, was a bit surprised. It's probably a boatload of money. I'd like to see some comparisons, I really wonder what the actual differences are.

     

     


    For me, the lenses appear to do something different at the micro-contrast level, to give extremely high resolution but without the clinical hyper-sharpness you get with other sharp lenses.

    micro-contrast, also quite a buzz word in photograhy when talking about zeiss lenses. When image editing / grading comes into play, how important and how noticeable is this? Sometimes it reminds me of those $10000 gold plated diamond hdmi cables... :)

     

    Don't mean to criticize, just very curious to see this compared to 'normal' glass.

  3. The only difference I see is the depth of field. The Voigtlander is focussed more to the front, so the bag in front is sharper. The sigma isn't as sharp there because the area is out of focus. That doesn't have anything to do with the sharpness of the lens though.

     

    What differences do you see? Btw, I can't see the files in original format, just 1.024px × 577px, or is that what you uploaded?

     

    Try focussing on a brick wall or something, so you can see the corner sharpness. I don't know how the Voigtlander performs in this aspect, but the 18-35mm is excellent.

  4. Sounds awesome.

    How are the chances of it working on fullframe?

    I could live with both 1.5x and 1.75x when using ML raw, but I suppose 1.5x would be the most friendly aspect ratio for 16:9 camera's.

     

    Monetary value would completely depend on the quality. If it has smeary corners and crappy performance with fast apertures like the LA7200/Optex I wouldn't want to pay much for it. If it is usable at f/2 and nice and sharp in the corners at f/5.6 - f/8, then it becomes another story. Somewhere around €500 sounds nice to me for the attachement, but probably you could ask at least double for a sharp single focus solution...

     

    Most important characteristic to me would be the bokeh.

     

    Btw, the Helios has a pretty deep front element. Wouldn't it work better if the anamorphic extention protrudes down towards the front lens? Like the Iscorama and it's 50mm lenses? Especially on fullframe...

  5. But since we are in the world of filmmaking, the standard is super 35mm which is smaller than full frame 35mm, s35 has a crop factor of 1.5x, thus this is my "full frame"

     

    That just depends on what 'your' standard is. Many (new) filmmakers never used or had anything to do with S35. If your understanding of 'fullframe' is an analogue 35mm negative, then just go with that.

     

    In short:

    If you want to match your GH3 with 35mm fullframe (photography negative) you should do 2x
    If you want to match it with Super 35 (fullframe movie standard), then the cropfactor is ~1,3x (2x : 1.5x)

     

    In other words:
    A 12-35mm lens on the GH3 compares to 24-70mm on a fullframe camera (like the 5D Mark III).
    A 12-35mm lens on the GH3 compares to ~16-47mm on a S35 camera.

  6. 4K sticker on a GH3. Very weak way for Panasonic to make it 'official'. Could they not have made a bigger and more imaginative splash than this?

     

    On the other hand, it's good to know what we can expect. It is definately a hybrid camera, not some kind of AG-AF101 successor.
