Sony a6000 extended capabilities

 https://www.dpreview.com/forums/thread/4498751


Hi all,

This is my first post on this forum! I hope you'll find it useful.

I came across an interesting thing that I would like to share:

I had a Sony a6000 for quite some time now, and while it's a great camera, it has it's own limitations.

One example is it's timelapse app - I bought an external power adapter to be able to take long (entire day, night or even both) timelapses. I was lucky enough that my second-hand camera already had the official (paid) timelapse app installed. The app does it's job, but it has it's own limits. One of them is max number of shots (990), another is the inability to reduce interval between the shots to less than one second (burst). But otherwise, the app works perfectly fine.

Another limitation however was more difficult to work around: I was looking at (cheap) options to add an external monitor to a6000 - turns out you can use your smartphone with Imaging Edge app and get live view straight away via WiFi. One problem though: for some strange reason, this can't be used for video. This was a huge disappointment, as filming would benefit from having external monitor.

I did some research and came across a page by some Vietnamese guy, who describes how you can work around this limitation. Turns out all you have to do is hack your camera and change it's model name from a6000, to something else like a6001 (I understand that it works because a6000 is on the list of unsupported cameras, but a6001 isn't).

I've tested this myself and can confirm that it works as expected, the whole process took me about 5 minutes.

At this point you can also install some other additional apps like unofficial timelapse app (without the limitations of official app), and a bunch of others.

The instructions are clear and easy to follow, details are here: https://chandat.net/multimedia/photography/huong-dan-bat-che-do-remote-control-video-recording-cho-sony-a6000/

The page is in Vietnamese, but can be easily translated.

Cheers

in short:
start the camera
open the tweak app
enable wifi and telnet
open putty, connect to camera via telnet
run bk.elf w 0x003e0005 49 4C 43 45 2D 36 30 30 30 to set camera model to a6000
run bk.elf w 0x003e0005 49 4C 43 45 2D 36 30 30 31 to set camera model to a6001 

If camera is set to non-existent camera model (like a6001), then raw images will not be reported properly and might not open in some programs (like darktable) - such raw images can still be read correctly by lightroom and perhaps other raw developers.

It's better to roll back the model change once it is no longer needed.

Medium format focal length equivalent

 
6 x 6 Crop Factor = 0.55
80mm on 6x6 is equivalent to 44mm on full frame

The GR III uses a slim optical system consisting of 6 elements 4 groups with a focal length of 18.3 mm (approx. 28 mm in 35 mm equivalent focal length) and aperture of F2.8.
 
Sony a6000 - crop factor = 1.5 - Sigma 30mm = 45mm focal length equivalent
 
Ricoh: 28mm
Mamiya: 44mm
Sony: 45mm

Fujifilm X-E3

Finally, I've made my decision and got Fuji X-E3 camera with 23mm f/2 lens.

First impressions: the camera itself is beautiful, very well made, high quality materials are used, camera is quite heavy, and with lens it's quite front-heavy.

Operation is far from what I am used to. Sometimes it's confusing, sometimes counter-intuitive.

Good example is the shutter speed dial: in theory you can set your shutter speed this way, in practice, you can also adjust shutter speed with rear dial, making setting misaligned with each other. 

Electronic shutter is a nice feature, making the camera completely silent. It's weird, as you can have the camera set to high speed burst mode, but the camera doesn't emit any sound at all. Nothing. 

Viewfinder is decent, although there is a delay when switching between LCD and viewfinder, much longer delay than on my Sony A6000.

Some buttons and their functions are confusing, but that's a matter of getting used to it probably.

The camera is quite heavy, and I'm not sure if I like it.

Having used this camera for a couple of minutes just now, I miss my Ricoh GR II. Now I understand the benefits of having a minimalist camera. Some cameras have just too many features - this is overwhelming, and often unnecessary. A good example is the shutter speed dial - do we really need it? We have two dials in addition to that, which makes the camera highly customizable, but again: do we need that level of customizing the camera? I don't think so.

In most cases, we set the camera and shoot. That's it. If it gets darker, we might change aperture. When we need to freeze motion, we can change shutter speed. ISO can be auto. For some unusual scenes, we might just put a camera still, and use a very long shutter speed, take couple shots, and get back to 'normal' settings. That's all there is. 

Still, it was good to have this camera, even if only to make me realize that minimalist, small camera is actually better. That's still a good outcome.

We want to be 'pro' photographers, who understand and use all those manual settings. But in reality, all we need is a simple A or S mode with exposure compensation and auto ISO, and M mode for special cases.

geotagging

Today it's easy to have photos placed on a map thanks to geotagging, which is embedding geographical metadata (location, elevation, time, date, etc.) within photograph metadata (exif). This is done automatically each time a photo is taken, especially with a smartphone.

However, when taking photos with a device that doesn't have gps built-in, no geolocation data is being saved and photo can't be easily linked with location.

To workaround this limitation, there are a couple solutions:

1. use a camera that has a gps module built-in (there are only a handful of those)

2. use a camera with a dedicated, external gps module (cumbersome, expensive, device is specific to particular camera model/brand) or use camera's bluetooth connectivity to connect to smartphone and pull geo metadata into the photos

3. use a separate, standalone gps tracker to continuously log your position and embed geo data in photos in post processing.

Options 1 and 2 are quite limiting with regards to what camera can be used (only cameras with built-in gps or bluetooth). 

Option 3 is most flexible, however, it comes with couple limitations.

Main issue is that you have to keep a separate gps device on you at all times, remember to turn it on, remember to keep it charged, etc. Also, memory storage in such a device is limited and gps tracks cannot be downloaded easily without a PC.

Next issue is that this particular device (Holux GPSport 245) is quite old (2011, got it in 2012) and company making it no longer exists, there are no more firmware updates, and software supplied with the unit is buggy and sometimes fails to connect to device or download the log. 

Fortunately there is a solution for that as there is an opensource software alternative: GPS Babel. It works on Linux and Windows, however, I've managed to connect and download the log only on windows so far.

Another issue is that some older gps devices don't record date/time correctly. This is because the date includes a week number which is a 10-bit integer value, which means it can count from 0 to 1024 weeks. Such a device works properly until week counter reaches 1024. When hitting this number, week counter rolls over, and starts again from 0. First time this happened was in August 1999, next time was 1024 weeks later which is April 2019, next time will be 1024 weeks later which is November 2038. This results in incorrect date being logged on some devices.

To work around this limitation you can simply download your gps log from tracker, and adjust (shift) all timestamps by exactly 1024 weeks (assuming your device was manufactured before previous rollover date - April 2019).

There is already a script to do that.

Finally, in order for geotagging to work, you have to keep your camera time and date in sync with gps signal/device. This will allow for precise photo placement on the map. It's probably enough to check and adjust camera time settings once every couple days - smartphone time should be enough as it is already synced to gps time. (I could use my GPSport device to read the time and sync camera time, however, since week rollover, unit no longer displays time on the main screen, or anywhere else)

Once all of this is in place, you can then import your photos to Adobe Lightroom as usual and then import gpx file on top of that - Lightroom will then read data from gpx file and embed geo data in photos based on their timestamps.

btw: geo data can also be embedded in videos and other media as well

Summary:

Once I get back from my trip, with photos on my memory card and gps track logged in my logger, I will then need to:

  1. download photos and gps track to a computer (Windows)
  2. adjust gps track data by 1024 weeks offset (Linux or Windows)
  3. import all photos to Lightroom (Windows)
  4. import gps track to ligtroom thus geotagging the photos (Windows)
