I have some scene representing i.e. buildings (long-distance) like :

cylinder { 0 10 y*100 translate <0,0,1000> }
cylinder { 0 10 y*100 translate <0,0,-1000> }
cylinder { 0 10 y*100 translate <-400,0,-600> }
etc...  (ofcourse cylinders will be replaced by complex objects)

and to speed up rendering I want to render it, and use it in final scene as 
sky_sphere.

What camera should I use in render-background scene ?

camera {  
 // ???
 location 0
 look_at z
}

-- 
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

AFAIK you can use spherical camera and 2:1 resolution.
