So...my 50mm 1.8 essentially disappeared.

These are the options I've discovered so far. And I want something unique and sharp/fast that I can use with my 70D (adapters if necessary)

Primes:

Canon F-TV f/0.95 $2000

Canon 85mm/50mm f/1.2 Mark I or Mark II $500-1200

Voigtlander Noxton 50mm 1.1 roughly $480-550

EF 50mm/35mm 1.4 USM $300-450

FD 55mm 1.2 SSC with Dandelion adapter. $230-750

Zooms:

24-70mm f/4 f/2.8

24-(105/104/135mm) f/4L, f2.8L, f/4

I want a lens that I can grab for under $300-$900 dollars however. And I want it to be SHARP and versatile. However, I'm done with the EF 50mm 1.8 II. (unless someone wants to be a kind samaritan and send me there Mark I for a reasonable cost) I need something that can fulfill the thrifty's job while being as useful as my 70-200 in closer ranges.

I'm not bleeding money but I really do need a new prime.

SCHOOL ME BOYS (and ladies)

What do you think? What should I spend my money on? What should I get rid of?

My kit so far includes a

70-200mm 2.8 IS USM II

70D - W

EF 18-55mm STM IS

EF 50-250mm IS

Also, if I were to go full frame (and is full frame worth it?)

6D or 5D Mark III (if I can find either for under a grand)

Currently, I shoot concerts and car shows. I have a couple weddings down the line.
