  1. Well the one time I used the a6500 on a b-roll gig, I got the heat warning and probably won't be bringing it as an A cam for any events unless they are under an hour.  

    So my vote is for GH5... Not sure how many weddings are under an hour!

  2. By now it should be obvious that if you need useable and consistent af-c this camera is not for you.  

    There's only 2 cameras I can think of with decent IQ that do it - $15k c300 mk ii and little box of compromises A6500.  I probably missed a few... Xt2? But it has no touch screen and no ibis.

    You will need to wait a while until the next cycle or two...

  3. Update: Focus transition does work with SB+Sigma 18-35mm

    Using the focus transition with the SB+Sigma 18-35mm does work provided you use the AF function from the camera to set the points.  Previously I used MF to set the focus points and this did not work as the camera would not return to the previously set point.  Presumably you should not touch the focus ring during the entire process or you might throw it off.

    Can't seem to update my previous post now.

  4. Ok stupid question from me: for IBIS with manual lens you input the focal length of the lens right?  (Not the 35mm equivalent with 2x crop factor.)

    For example you put on 50mm lens, you enter 50mm.  You use normal speedbooster and 50mm, you enter 35mm.  

    Is this right?  The manual doesn't explain this. I got confused the first time I used it and put in 70mm for SB+50mm (35*2)

  5. Re: tap to focus.

    I'm assuming you mean during recoding.  Tap to focus is a bit stupid right now, they should add some options in menu to customize behaviour.

    A6500 makes sense - you tap, it moves focus point and focuses (let's not talk about the other stupid things with it).

    For gh5 in M mode - you tap and nothing happens.  You have to drag the current focus point to make it work.  And then to add insult to injury it doesn't focus as smoothly as af-c for some reason.

    In af-c mode it's worse.  You can tap or drag, but then there is a delay, and it changes to the adjusting focus point screen. Then you have to click set on the touch screen to finally adjust the focus point (if you don't press anything it will focus on the new point but you can't get back to regular display without pressing set or cancel). Oh and by the way the "set" button is all the way in the bottom right corner.

    Hopefully they make this less clunky in next firmware.

  6. In the wedding processional AF vid, the background is pulsing in the first few clips.  In the last one with the same settings (AF speed 5, sens 3) it is pulsing less.

    I still think A6500 AF-C far superior for video AF.  GH5 makes me think 3x about using af-c.  It's not the worst thing in the world but it's also not consistent enough for "prime time".  I'm not saying it's unusable, but it has a higher chance of not doing what you want it to do vs the competition.  IMO you're rolling the dice when you use it.  Maybe with firmware tweaks it will improve but there's only so much you can do with CDAF.  

    I really wish they licensed or bought some of the other AF tech, that would have made this camera really great, like almost next level.

    I don't regret my purchase too much, it's got a lot of great features and the people I work with are really looking forward to the 4K 60p.  Just wish the AF-C was better, that would have sealed the deal for them and avoided this whole controversy (although I'm sure we would have found something else to complain about, like someone said the audio is not seamless between long files?  still have to test this myself).

  7. I just updated my speedbooster (T model, mark IV) and played with Sigma 12-35mm F1. and GH5.

    Some observations:

    IBIS isn't that great with it but better than nothing.

    AF works

    AF-C doesn't really work well.  It actually does ok if the subject approaches the camera, but if you are increasing the distance it hunts like crazy and then doesn't focus.

    Focus racking in camera does NOT work with this combo.  I was kind of disappointed in this one :(

  8. I think "the large portion of video shooters that never use AF" is not because people don't want to but because the tech/cost isn't there.

    If every camera had dual pixel video AF from the year 2100 you can bet almost everyone would use it.  I barely use continuous AF in video not because I don't want to, but because it's just not very viable on most cameras.  Can you imagine if there was very good object tracking and almost perfect AF?  Would be amazing for gimbal and run and gun. 

  9. I have the mc-11, SB ultra IV, sigma 18-35, 50-100 and a6500. Performance in movie mode is unacceptable for af-c.  Also even though you can see the mc-11 18-35 combo work on YouTube, what they don't show is that the AF motor is constantly chugging even if everything is static.  The SB combo is slightly better in that eventually the AF motor chugs less but it is still working almost all the time. I don't think the AF motors were designed for this and Im not willing to tempt fate and burn out the AF motors.

    Imo the only option that works well are native e mount lenses for af-c in movie mode. Even on the sony 18-105 the AF motor (very quiet, I have to put my ear right next to it) sounds like it is also always on but doesn't make any weird noises so I assume it is designed for af-c mode.

    Had I known about the AF motors constantly chugging and hunting on adapted lenses I would probably not have bought all this stuff and waited for a different option.  

    For af-c I just stick to the Sony 10-18 and 18-105.  Otherwise it's manual focus for me. 

    My guess is that they should somehow change the adapters to read an average step direction over time for the AF motors instead of constantly moving back and forth even in static scenes.  But I assume it's more complex than that to reverse engineer it.

    Also my canon 70-200 f2.8 and f4 don't seem to like the adapted combo very well and don't focus over half the time.  I think the f4 is even worse since it's older and doesn't even focus in photo mode. I haven't used it in a while so I forgot exactly what issues these combos have.

    Just get your facts straight and you will be fine.

    - 5D3/D750 aren't 4K cameras, so no 4K monitor can help you there

    - The monitors we are talking about are NOT real 4K monitors, is this comprehendible enough for you?

    - Full frame focus with 1.4f lenses is almost impossible to focus right for more than 1 second - or less, even if you had a 65" TV worn on your  head, it isn't about the monitor/screen/focus peaking, it is about physics. That is another huge conversation, about the 5Dii revolution, and the effects on moving image mentality and psychology, not for this topic. 

    That's what I said, that's what you seemed missing completely, people with less knowledge are reading these forums, and they will try to find 4K monitors to use with their D750, or else they won't be able to pull focus with out a focus puller on 1.4f lenses, filming a soccer game.

    I did not call you anything, I just disagreed with your generalities and offered facts to your myths, while it is truth, people didn't use 4K monitors until a year ago, and still just a wee tiny portion of video makers have a true 4K monitor (something like a 0.4%) to help them with focus, do you disagree with that?

    My facts are straight.

    - Using a 1080 signal for focusing using a monitor is very difficult, regardless of monitor size or resolution.  I used example of D750 because I have used it in past.  But it applies to almost all current cameras if outputting 1080p from the 1080p mode - even A6500 in 1080p mode.  Do you dispute this - that using a 1080p signal for focusing using monitor alone is difficult for shallow DOF and critical focus?  Also I brought up those cameras to make this point that the mushy signal is a problem for focusing, but I'm not sure if you can understand this...

    - I never said any of the monitors had 4K resolution, in fact no one said that in this thread, but we were talking about accepting 4K signals.  Is this comprehensible to you? Nice usage of alternative facts btw. I purchased my monitor last year when no one was talking about 4K monitoring but obviously I am idiot and don't know the specs of my own monitor right?

    - I mentioned 4k input because I used 4K signal from A6500 to a full hd monitor that takes 4K signal.  I know the monitor is not 4K resolution.  However, the monitor is much sharper using the 4K signal vs the mushy 1080p signal.  This increases the usability of the monitor for focusing purposes.  What do you not understand about this?  I am saying that using a 4K signal on a monitor that only has 1920x1080 is sharper than using a 1080p signal on the same monitor (when discussing the recording mode of the camera, 1080p or 4K mode).  Have you even tried this, are you saying it makes no difference?  Are you saying this point is useless?  What "fact" is not correct here?  I have not tried to see if in 4K mode the A6500 can output a 1080p signal and what quality that is, so I'm not sure about that part.  

    - When the camera is locked down and you are doing a focus rack with shallow DOF, are you saying that this is impossible?  Why are you assuming that every shot must be moving... Are you telling me it would not be helpful to have a monitor that is very clear so that you can do a simple focus rack properly?  You literally just said using FF and F1.4 "focus is impossible for more than 1s".  So for any shot you are saying it is impossible and therefore useless?

    - I never said anyone was using 4K actual resolution monitors, in fact no one in this thread said anything about the current or past usage of 4K actual resolution monitors - where are you even getting this from - please answer.

    What facts did you offer against my "misinformation"??? Please make a clear list.

    I used F1.4 as an example, but even FF F2.8 etc is difficult to focus with.  Everything I wrote was about how difficult it is to focus using 1080p rec mode and external monitors.  It is the opposite of "buy external monitor = ez focus ez life".  What myth am I propagating?  I never said 1080p signal on 4K monitor would make it easier.  Where did I imply this???!  I haven't even listed a 4K display resolution monitor! You are... making things up... If you read what I wrote, I said 4K signal to monitor makes it easier to focus, but still not perfect.  Why would someone with a D750 which has no 4K buy a 4K monitor based on what I said.  Please explain the logic here.  D750 has no 4K rec mode or 4K signal... 

    If you can't answer these questions it means you're just not reading and obviously nothing I say is going to make a difference so... you can be right!  You win!
