Hello, I'm pretty new to Photography, I use a SonyA7iii and want to be able to photograph Football(Soccer) games and wild life from a distance with a good zoom and I was thinking of getting the Sigma 150-600mm lens and happen to stumble across the A mount version of the Sigma and was wondering what mount adapter I would need for my A7iii? Thank you! -

While DR as posted by DxO and Photons to Photos may be 'marketing', it's still a useful tool to compare cameras since testing is controlled. It's good information to help someone make a decision. As for actual use, I become accustomed to what my camera will and won't do and learn to shoot within those parameters. -
Interesting methodology, and somewhat useful I guess. The only thing you're missing here is that you assume the sensor is ISO invariant. Most new Sony sensors have a dual gain sensor, which improves dynamic range at higher ISOs by about 1 stop. In practice this means that you'll get better results if you raise your ISO in camera than to push exposure in post. You can actually test for this with your procedure by varying ISO rather than shutter speed and then normalizing the exposure in post. You'll likely find that you'll get slightly bigger dynamic range than you did with your first procedure.
