I want to ask for your help. I have 70D and yet as I managed to get good results from the camera, I'm still not really impressed with noise performance and AF reliability. I have a lot of pictures off focus, soft and not satisfying to me. I have few L lenses (70-200 f/4, 100-400 II, 24-70 f/4) and to me it seems, that 70D works well only with 70-200, other ones are a bit soft and not satisfying.
So I decided to go away from 70D and want to upgrade to a newer camera. My question is which one?
I shoot moving subjects, like airshows, planes in general and occasionally Formula 1 events. I find 70D burst mode more than enough in terms of speed, just don't like the accuracy of it, especially on AI Servo mode. Also, the image quality is huge matter to me and 70D hasn't the best one - lack of details in trees, etc.
So I would love to have some camera with more reliable AF and better IQ with lower noise. I found out, that it's not really easy to get one with this in Canon region without selling a kidney (which I have only one now as I bought 100-400 II).
I really like the output from 6D mark II, but I'm affraid, that it's AF won't be as precise and reliable as others say. Also, less reach with FF camery. Second candidate is 7D Mark II as it has really, really great AF system, but, the IQ is really near of 70D and I guess, there is no upgrade that way. It's as old as 70D and I also kinda grew in liking the articulating screen.
5D Mark IV is off my limits and 80D seems to me like 6D MkII with worse IQ. 6D MkII is probably the highest I can go with finances.
So I'm kinda confused which one to go.
Could you please help me?
Thank you very much.
