I am looking at getting a 135mm (and possibly 180mm) lens.

Most of the ones at these focal lengths I am interested in..rodenstock and schneiders are apo lenses.

I have read in some places that these apochromatic lenses are corrected to focus with the three primary colours on the film plane and as such are designed to perform in close up work in particular and they are not so good at infinity focus work unless stopped down.

Now for much of my work I like to be able use lenses close to wide open and almost always at infinity focus so will I not get good results from these apo lenses?

If not would this mean having to go for a nikon or fuji lens at this focal length even though in general I prefer to use the rodenstocks where possible.


Thanks,

Marc
