I purchased the lens a number of years back when I bought my CP990, and kept it for the CP5000. It has a zoom range equivalent to 139mm to 170mm without vignetting. Since it is only a maximum of 170mm, it is still easily useable. If you have used a 200mm on a 35mm camera, it is very comparable.
Though I only use it on perhaps 10% of my shots, it is still worthwhile having, and I normally carry it. It is light and compact, unlike the 3x.
It is a moderate telephoto, and simply does what it is expected to do. Nothing spectacular, no particular problems, it is there when it is needed, a workhorse - not a racehorse.
