After 10 years on Poser, all my cameras have evolved to 52- 55 focal... I don't have the science as to why but I suspect it ma y be a quirk from older versions. So, 35mm is closer to 52mm in set in Poser, etc. Higher focals like 95mm seem to not only flatten the render but bend the corners up as well.  Something seems wrong. I just think you have to work around this to your own liking.

I do not own a camera so, mho.
