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.
+1. Find your style first before buying all that extra stuff. You may find that you use a filter about once a year. Don't buy anything until you find a definite need for it. Try without it. You might find a cheap workaround. For example grad ND - I find lightrooms grad filter way more flexible or take two exposures and blend in photoshop. For ND filter - f/22 does the job (well kind of!). Maybe a CPL is one you will need as thats not possible to replicate digitally. Tripod - my knee, lampost, railing etc. even used someones shoulder once.
When you catagorically cannot go further - then buy it.
I can agree to almost anything except FLASH. I consider flash as one of the most important accessory besides lens and camera. You can use it as a fill-in flash which makes portraits a lot better. It's also a great help for extending a little bit a picture's DR. I can live without a tripod (most of the time) and filters but I consider flash as a must whenever I take pictures except for some situations. You may argue that 6D can take a much higher ISO but when you know how to use your flash properly, your pictures will be a lot better.
Well, yes and no. It is a must-have in studio-like conditions or staged scenes (portraits or macro), but for candid or street photography flash can make it look unnatural and be embarrassing for people around you. However, I'm no flash expert, so I may be wrong.
I know that good photograph needs good lighting and outdoors there is plenty of it
