Support for Sony NEX-6 and a6000 #120
Comments

Is it working with Sony A6000 now? Or with any other from the Sony mirrorless line? A6x00 series? A7 series? |

No support for Sony. You're welcome to add it though. It would be appreciated |
|
Your work is great. I very much appreciate it. I wish I could provide support but I m afraid I cannot. My programming skills are nowhere sufficient.

if you put 4 raw files from whatever sony camera you have into a google drive zip link I'll take a look. Put 1 focus point in the center and for the others move the focus point somewhere else. No promises. I've never seen sony add the metadata to an image yet, but I've only seen center shot raws. |

You are great. Will get that done right away.

I uploaded 15 raw files. All taken with Sony A7Rm2. There also are 15 txt files with the exif data. 1 xls file explaining my settings as I took the photos, 2 mov files showing how AF-C looked on certain cases.
You mentioned that Sony does not provided enough info on exif. Below are the tag names I found relavant to your work. I plotted some focus related data on Excel, looked very meaningful.
Focus Mode : AF-SAF Area Mode Setting : Flexible SpotFlexible Spot Position : 65 419AF Zone Selected : n/aAF Points Used : (none)Focal Plane AF Points Used : (none) **Focus Location : 3984 2656 404 2318AF Area Mode : Flexible Spot
Focus Position 2 : 155Exif Image Width : 7952Exif Image Height : 5304Sony Image Height : 2656Sony Image Width : 3984
** "Focal Plane AF Points Used" has values when AF-C is used.
I wish I had the programming skills to help but this is all I could.
All the very best.

I extracted the exif data on txt files using a software I found on the internet: ExifToolGUI

Hi, Can you try opening the ticket on the web and not replying from the email? The links aren't coming through. |

hello. |
|
For 9856.txt The above are most likely the values that are needed. From what I'm seeing, the only thing that would make sense for where the camera focused is the |
|
I believe this is for 9865.txt For Focus Location, what I understand is we have a 3x2 area of (0,0) and (3984,-2656) and that the camera's AF can scan from (404,-332) to (3579,-2318) on top left and bottom right respectively. Sony a7rii has 399 PDAF focus points. That would mean I should be able to move my 'small' flexible spot in an area of 21x19 but the fact is I can only do it 19x17. That means the smallest spot the camera allows the user is larger than a focus point. I covered the x axis with 19 test shots and looked at the x axis increment value in between each shot: 2x93 and the rest either 186 or 187.. In my opinion Flexible Spot Position looks meaningful much like Focus Location but maybe in a 4x3 area.. I guess not I'm not much help ... PS. |

I think this is going to be too complicated for me to do with having access to a Sony. Unfortunately we're at the mercy of someone else adding support for the camera. |
|
I could find some time in the next days, if I don't run into unforeseen troubles, to run more tests. I have the NEX-6 and the a6000 (the a6300 is on its way). |

Hi guys, are there any further plans to support Sony? |
|
Support for Sony cameras would be nice! |
This work is based on files from an a7r3, so it may not work with other models. The values used for calculations are guesses based on marketing material from Sony and trial and error. The intended features are the following. * Show the focus point that was used * Show the outer frame of the PDAF area * Show active PDAF locations Most Sony cameras that have PDAF only use it down to f/8 and only over a subset of the sensor, so the lack of related EXIF data should not be an error. No attempt was made to support eye/face detection, nor to identify the specific focus area used for a given image. Related to musselwhizzle#120
Hello.
Nice job, and as per subject, I'd like to see support for those cameras. If nobody has objections, I'd fork and try the patch myself.
Notes: I'm a very experienced programmer and in the past I've also done a lot of reverse engineering work with EXIF and RAW metadata manipulation. Unfortunately I don't have experience in LUA. So, while I'm willing to try it, I can't be sure I'll be good on that. My message is: if somebody else wants to start working on the Sony support, please don't be blocked supposing I'm already near to provide a solution.
