If you were to design a lens, say 80mm versus one that is 180mm, would
the shorter design typically be easier to design with better resolution?
In other words, if the lens is a longer focal length, it is more
difficult to produce higher resolution compared to shorter focal lengths.
Anyone know?
Resolution is really not the issue, Peter. In VERY general terms,
resolution can more readily be achieved in shorter focal-length lenses
but it is not difficult to produce a high-resolution long focal length
lens. There are too many other optical parameters demanding attention
to concentrate on resolution.
