Looking to upgrade from my 60d.
I do not use the 60d underwater because at the time I didn't want to invest in a housing for a camera I knew I was going to replace.
My next camera will go underwater. My dive sites are typically darker waters like the great lakes, St. Lawrence River, etc. I have some lights but I mostly like large wide angle shipwreck photos where strobes don't really help.
I also use the camera on land. My main reason for upgrading is poor low light performance. I could pick up a used 5dII and used housing at a good price. My other option is the Canon 6d. I really like the wifi features and connecting to the iphone to shoot and offload photos. This will be a good feature as well.
Anyway, of the 6d and 5dII which has the best low light performance? Or is the difference negligible?
Some other things to note:
I don't need the multiple focus points on the 5dIII
I would like a weather sealed body, but it's not necessary. I can't tell if the 6d is sealed, but I think it isn't.
I already own some L lenses and will stay with canon.
