Ah yeah, thats definitely important. You can even find lenses of the exact same focal length or zoom range, but with different optical properties. Pentax DA primes really spoil us in terms of flare and ghosting resistances. DA limiteds are formidable lenses and hold their own even against modern big, expensive monster zoom lenses.
This is also why I say that sharpness is not nearly as important as many people say. Overall optical rendering can be more important, things like colours, contrasts, CA, flare
