Hi, would like to seek advise from the bros here on whether I should upgrade to 5D2 or not 
Am currently using 7D and have the following lens or in the near future.
1) Sigma 20mm 1.8 / Canon 20mm 2.8 ( Still deciding )
2) Sigma 50mm 1.4 / Canon 50mm 1.4 ( Leaning towards Sigma )
3) Canon 85mm 1.8
4) Canon 135L
5) Canon 100-400
6) 18-55 & 55-250mm ( Bought them together with my 500D for my GF cause its light )
Please feel free to suggest on item 1 & 2 if you have experienced the lens.
Given that im using a 7D, I would like to know how great is the improvements from 7D to 5D2 in terms of colors and sharpness and the low light high ISO which MkII is famous for
I have been using 500D for a while and do not have any problems with the fps nor the AF ( Unless someone tells me that 5D2 is slower than 500D on the AF portion ?? )
I know that I will miss some function on the 7D ( One touch this and one touch that )but do not need them when Im using the 500D previously so I guess I can live without it.
Also, one thing to consider is that I do not have a shooting preference ( Potrait, landscape, sports etc ) which means I just shoot everything and also I do not know much about post processing. I use canon DPP for adjustment and sharpening.
With such amazing post processing skills any bros thinks that Im eligible to change to 5D2?
And let me know if i have left out any important points in my consideration process
Thanks alot in advance
