Sony A6700 exposure issue with Auto ISO

Hi everyone, I'm having an issue that might be due to some bad config on my camera but I can't seem to find it. I'm using an A6700 with a Sony 200-600, previously I owned a Nikon D7200 with a Sigma 150-600 and for birding I used manual mode, setting shutter speed and aperture and leaving a floating ISO (Auto ISO), which worked great.

I tried this with the A6700 and for some reason the pictures come severely underexposed, so I have to mode to manual ISO so I can even properly see through the EVF. I have a wide range for AutoISO (the default one), I tried the different exposure modes, exposure compensation is at 0, so not sure what might be off. 

Today I tried testing in Auto mode and it's exposing correctly, but if I choose Shutter priority or manual mode for example, they get underexposed. I'm attaching some example images and settings, let me know if you have any idea on what I could look into, or if you want me to show more settings. Thanks a lot! :)

 

3711 is auto mode. 3712 is shutter priority with 1/800, 3713 is manual mode with shutter speed 1/800, aperture 5.6. 
Uploading the others to imgur because it's telling me it's more than 1000kB when it's 200kB, weird.

What ISO value did the camera choose in photo 2 and 3? What AutoISO range did you set?

Auto range was default (it's on the screenshots in Imgur I uploaded) but it's something like 50-100500. For photos 2 and 3 it chose ISO 100. When taking the pictures it said Auto ISO until I half-pressed and chose 100.

I had tried all the metering modes and made no big difference.

I ended up resetting the camera with "Initialize" because I tried a lot of things and nothing worked. Luckily now it's working just fine.

      JPEG options?

      By XKAES · Posted

      I'd suggest you start by running a simple test.  Take pictures of a typical scene/subject and each of the JPEG settings your camera offers.  Then compare them in the output that you normally produce.  You may or may not see a difference.  I normally shoot at the highest JPEG level and save that file -- but make a smaller file (lower resolution) for normal/typical use. There's plenty of editing that you can do with JPEGs on your computer -- depending on your software -- and there are features in your camera that can help out, as well.  That depends on your camera.  Put them together, and it might meet your needs.  For example, your camera probably has several bracketing features that will take the same shot with different settings with one press of the button.  Then you can select the best JPEG to work with on your computer.  I frequently use this feature to control contrast.

      JPEG options?

      If you set up some basic presets in your processing software and use batch processing, you don't need jpeg at all. I shoot RAW only, use (free) Faststone Image Viewer which will view any type of image file to cull my shots, and batch process in Darktable. I can start with 2000-3000 shots and in a matter of a few hours have them culled, processed, and posted. A handful of shots, say a couple hundred from a photo walk, are done in minutes.  This saves card space, computer space, and upload time.  The results are very good for posting online. When someone wants to buy one or I decide to print it, I can then return to the RAW file and process it individually for optimum results.  I never delete a RAW file. Sometimes I'll return to an old shot I processed several years ago and reprocess it. I have been very surprised how much better they look as my processing skills improved.

      If you're only publishing small-sized photo's or viewing on a phone / computer screen, 12-ish MP should be more than enough for your needs. Since with JPEG, the ability to 'fix' stuff on the computer is very limited anyway, you're not giving up much except the ability to crop/recompose after taking the shot. If you tend to crop often or might print large, shoot fine quality instead as JPEGs don't take up a lot of space anyway. I tend to shoot RAW+JPEG. After a trip/shoot, I download my photos to my computer and quickly scan through my JPEGs to select my keepers. The JPEGs are fine for 90% of my needs but at times there are one or two 'WOW'-shots that I might one day print large. I'll edit the RAW of these photos to my hearts content, generate a JPEG, then delete all RAWs to clear up space.
