I recall seeing a Nat Geo Special about how photographers could never get close enough to hyenas during a kill to video it nicely. I can't find the video (It was shown on cable) but one of them got off the truck and with time, eventually got close enough to video it. Now they said it was impossible, And I'm not a wildlife photographer.
Even so, That nat geo guy wagered that the better shots are closer. It was true, because of its extreme difficulty. They could have shot it at a distance but It didn't look as good.
It's the same that even though someone having an amazing 1Dx with a 600L, If you got close enough with that A1400 and got a great shot, It would better than those 600L shots. No doubt in my mind.
So yes, an Great A1400 shot from a unique perspective can best a 600L shot from every other perspective everyone's been shooting at conveniently.
