Thank you Viktor, very thorough answer, I wish I could get answers like this always 🙂
One more thing: I like lowlight photography (not only) and in that matter I know a7s is good lowlight performer, but on the other hand a7ii has better dynamic range, what do you think ?
Is there any chance that you can explain (more simplify explanation) in regards how alpha series (a7, a7ii, a7r, a7rii, a7s, a7sii) are and what would be best one for a every day in the hands of an amateur enthusiast?
Once again thank you
