I regret that I didn't start with a FF camera. I didn't know what to get, so I tried to follow the most popular advice for beginners, which was/is like:
- body doesn't matter, half-dead Rebel is fine
; (not for me
- get the best lenses you can afford ...; (best doesn't mean the most expensive
- ... which are 11-16/2.8, 17-55/2.8, 70-200L, 100-400L; (not really, primes work better for me
- don't forget about accessories: tripods, flashes, filters, etc; (you can buy these later, if you feel the need) (IMHO, only memory cards, bags and spare batteries are the must-have, everything else is optional
Now I know that it does not fit my style. I don't need to cover the 16-600mm focal range. I rarely use tele lenses, flashes, tripods, filters ... no need to spend money on that. I should have bought a used 5D with 50/1.8'II and then add 85/1.8USM later (which I recommend for portraits).
The problem is that you never know before you try it. My current choice is 6D+40/2.8STM (people, close-ups, stitching landscapes, travel) +150/2.8Macro for portraits and stuff outdoors.
