    Question sensor temperature for Fujifilm X-A1



    I'm trying to get some idea of the sensor temperature for my Fujifilm X-A1 (when using it for AP on my Meade f/9 102mm).

    With my Canon 450D hooked up to APT, I get a temperature reading for every frame (light or dark...).

    I can't hook up my Fujifilm to anything but a intervalometer AFAIK.

    Is there some way of getting a sensor temperature from the data stored on the frames? For this camera or any other DSLR?

    How does APT (AP Tool) figure out the sensor temp for the Canon cameras?

    Clears,
    Joe

    APT simply asks the Canon camera through the USB connection what its temperature is. If your Fuji does not have a USB connection, it won't have that option. The camera may or may not encode the temperature in the EXIF data that accompanies the image. EXIF data is entirely optional, at the manufacturers discretion.

    If your camera does not have a temperature sensor, the data will obviously not be included. Your best bet in that case is to use the air temperature as a proxy for camera temperature. I did that for several years with my Canon 350D.

    Thanks, Keith. Let me look into the bit about the EXIF data for Fujifilm X-A1.

    I know from using the Canon 450D that the sensor temp tends to run about 5 degrees Celsius hotter than ambient temperature. I suppose something similar happens to the Fuji X-A1.

    But I built a small add-on Peltier cooler for the camera and I wanted to get an idea of how much it was cooling the sensor (without having to insert a device near the sensor. (I'll explain more in a thread for ATM later). In the meantime, I know that, away from the camera, the cold side of the Peltier is 15 degrees Celsius cooler than ambient temperature.

    So I guess that as good an approximation as I can hope for.

    Clears,
    Joe

    Looking at the EXIF information in the SilkyPix raw converter GUI I don't see the temperature so it probably does not have it.

    I did a lot of checking. Fujifilm is actually pretty pathetic in this regard. Hardly any info is recorded in EXIF.
