Well, you know what they say.. "The best camera is the one you have with you."
Something like that anyway.
Nothing beats a full frame with some proper glass in front of it though.
Specially if it is a good old vintage lens.
Try it one of these days if you can, even on a cropped sensor.
The "pain" of manual focus will make you think every shot in a completely different way, and evolve as a photographer way faster than "cheating" with all the bells and whistles attached to modern gear.
