look at the shadow on the front tires... you don't know the lighting conditions nor the settings that i had to use to make it happen... the noise is because it's heavily cropped, i shot it much too loosely, but with 36mp, you have room to make up for mistakes.
can't do that with m4/3, not at all.
Just to be clear you explained you cropped the image. The noise and heavy post processing show that. It is grainy. That not at all an issue: the quality is good enough but it show that there not much absolute quality in it.This is not a 36MP picture anymore and you could tell us but I'am not sure it is even 24MP anymore. Maybe there only 8-10MP remaining. And due to the lense this would not be even pixel sharp.
So then another photographer could have beeen exactly at the same position as your and could have used exactly the same lense, apperture and focal length. It could have used an A6000 instead of A7R, taken a bit more care of the framing and got exactly the same result but indeed with more definition as the sensor has greater pixel density... For aspects like noise, bokeh etc, once the crop is more agressive than the APSC crop factor, as long as the APSC shooter frame less carelessly then he will get exactly the same thing... After all it is exactly as if you choosed to use your A7 in APSC crop mode and framed better.
If the crop is heavy you can extend that to m4/3 too...
There another option. The 60-300 tamron adapt all is far from being the best lense in the world. So the APSC used could have well add used some 70-200 (for example the tamron that one can find used for 450€) to have the same possibility for not framing too carefully and to get as much detail. With a bit more open by 1 stop the level of noise would match. With more carefull framing than you did, he would have got a technically superior image, even with APSC.
And this can be extended to m4/3 too. They have some truely great pro lenses you know.
You took an FF to shoot, you post processed it quite a bit and all of this got you a great image without much detail if you want to be picky. That not important because well anyway our eyes can't benefit for 36MP or even 24MP. It could have been better with better post processing (removing the noise). Could have been better with a better lense. Could have been better with more carefull framing.
The format was a factor among many other and so was not the limiting factor in this case. Sure if you don't want to get a better lense, or to frame better or to improve your post procressing skills, that may be a "free" asset to you. You spent less on the lense, are restricted to MF but got a bigger sensor. One could have used a better lense and a better camera. Or same lense, APSC camera and a bit better noise post processing software (like DxO Prime).
In anyway, there chances in 3-5 years that far less expensive camera with smaller sensor will do as good or better. But the better lenses, they would stay exactly at good. When somebody invest in gear he should think carefull when it is worth to invest more on lenses, when it is worth to invest more on camera, when it is worth to invest more on post processing skill.
Still the best investment by far would be by far to invest to become a better photographer.
