Why putting low end lenses on expensive full frame cameras?
Personally I prefer getting some high quality lenses first then upgrade to a FF.
Canon has the EF 24 f1.4L II and EF 35 f1.4L and both are very sharp and create great bokeh with the 24L II having less chromatic aberration.
I am sure Nikon has similar lenses too.

This.

Coz I have no money for all, and atm I prefer to go up with ISO easily.

There are a lot of non that expensive lenses that work fine also if non L class.

take 100 f2, 85 1.8, 50 1.4, etc, all of them are fine and fast.

5DII has at 1600 iso or maybe 3200 the noise mine 40 D has at 400... So I won't spend 1300 euro on a 34 1.4 (that has not weather sealing btw) to gain only one stop and to have a 50mm equivalent on my camera, when changing the body with not much more money I can have 2-3 stops and double resolution.

Btw the aim of the topic is to have suggestions about the lenses I asked.

I appreciate your efforts but I am informed, I read a lot about this things but I would like to have comments from someone that has field experiences with this lenses...

the 5DII doesn't have considerable noise in an 8x10 print until you hit 6400. If you pixel-peep, that's another story.

Even better
