Buyers help: 5d mk ii (USED) + eventual lens upgrades OR 5d mk iii

[tannyboy]

Hey all just want to your thoughts on the state of the land right now.

my setup is currently a

Body
40D
Also currently out with fiancee and brother my: 30D & 350D

EF-S Lenses
Canon 10 - 22
Sigma 30 1.4 (can be mounted full frame with vignetting)

EF Lenses
50 1.4
135L
Sigma 24 - 70 f/2.8

Looking at the market at used bodies (haven't bought a new body since the 350D) and the 5D mk II's seem like they are going for a steal (relatively speaking).
The lure of going full frame and getting that extra ISO oomph is getting stronger.

So what are your thoughts.

5D mk ii + a nice new lens - potentially a wide zoom to replace the 10 - 22

or

5d mk iii [no new lens as the fiancee would hurt me if i spent all that in one hit]

or

WAIT and get a 6D

Strange feeling I could get the first option below the cost of the second quite substantially.


What I shoot? Bit of everything, dabble in portraits, events, some sports. Be no means a pro - but i'd put myself in the advanced amateur category.


Love to get everyone's two cents on this .
