  1. Sounds like you need to go for the Sony f4 zooms. For run & gun with a full-frame cam, I doubt you would ever want shallower than f4 anyways. Unfortunately selling the Canon stuff won't cover buying the Sony's.

    Your 17-50 is an APS-C lens, so assuming you want the ability to shoot your wide to normal FOV's on full frame, you would need to replace it anyways. 

  2. Don't forget to consider the usefulness of 4K for getting multiple crops/framings out of one camera (assuming you're finishing in 1080p). This can be useful for interviews.

    I would also consider avoiding moire very important. In my (admittedly limited) experience shooting interviews, inevitably at least one of the subjects is always wearing the Super Moire Special print from Bob's Big House of Dancing Shimmery Shirts Warehouse. Aggravating!

  3. GH4 has more (deeper) DOF for the same subject composition because you have to either:

    - Be further away from the subject to get the framing (longer focal distance/closer to infinity = deeper DOF)

    or

    -Use a wider/shorter lens, to maintain the same subject framing at the same distance. Wider lenses have a deeper DOF.

  4. Lens sharpness is different than electronic processing sharpness- which is what the GH's have always gone overboard with at default settings. They also do additional processing when you use native (electronic) m4/3 lenses, to correct each lenses' shortcomings (edge softness, CA, etc). Just turn the sharpness setting down and use your NLE to sharpen to taste, and/or use non-native (not Panny or Olympus) lenses.

  5. would I be better off going with a more modest body like GH-2 as opposed to the GH-4 and building up some glass first and investing in things like a good tripod.

     

    If you are starting from scratch, yes, absolutely. The ~$1300 difference between a GH4 and a used GH2 will go a long, long ways towards all the peripherals you need to shoot effectively.... tripod, lenses, cards, audio gear, bag/case, lighting, etc. This gear will make a much larger difference in your end product than the GH4 over the GH2.

  6. For pretty much anything not involving fast motion, it's really quite silly to compare the GH4's 200mb/s mode to its 100mb/s modes, or the GH3's 50mb/s modes: those are IPB, and the 200mb/s is All-I. IPB is vastly more efficient with its bandwidth, so long as you don't have fast, continuous motion over most of the frame.

    Compare the GH4's to the GH3's or 5DIII's All-I modes, and there won't be nearly as much complaining.

  7. h.265 is great, but in terms of editing, we're right back to where we were in 2009 or so- affordable or near-affordable computers don't have enough power to decode it smoothly in real-time, so we're stuck transcoding to an un- or less-compressed format. In a year or two or three the software and hardware will catch up and we'll be where we've been for a couple years with h.264 (native editing, smooth playback).

  8. EF-S glass (APS-C lenses made bt Canon) will not fit because of their reduced flange distance.


    Flange distance is exactly the same as EF. The reason Canon EF-S's won't fit is that most of them have a protruding lip on the back of the lens that would hit the SpeedBooster's optics (or the mirror on a full frame camera).

    I do remember seeing an article somewhere online though, about shaving the lip off to clear a 5D's mirror. Perhaps this could be done to clear the Speedbooster optics? The 17-55 f2.8 is the only EF-S lens I can think of that'd be worth this kind of effort.

    There's also the question of whether the electronic protocol is different for EF-S.
  9. I wonder how long, or how many camera generations still do we have to wait until most cameras sold for video have a global shutter or something else to eliminate the rolling shutter issue. One could think a thing like that would be a high priority, but apparently it isn't, or it is very hard to battle.

    It's just an engineering challenge I believe. There would actually be significant stills advantages too- faster flash sync, silent shooting all the time, and I'm sure camera makers would love to forego the expense of a mechanical shutter mechanism.

    Unfortunately as of right now it seems the global shutter circuitry just compromises the sensor's performance too much. I think a compromise-free global shutter is at least five years out.
