The other is the SP35-80, f2.8-3.8: model 01A. This is a much more modest lens, with a limited zoom range by modern standards, with no brass plaque on the side, but also is widely considered unusually good for a zoom lens. Its most notable feature is that the extends a long way and puts in a very respectable performance as a close-up lens: it goes to 1:2.5 without tubes or converter, or almost to 1:1 with a 2x teleconverter, as you will see from the markings on the barrel.
Some shots with it, the one of the matchbox car being completely un-cropped. They are all stopped down a fair bit and the car is on f22.
Am I praising them like Peter? Yes, but perhaps with more reservations. The SP180 is very heavy and makes me appreciate a modern autofocus lens, and though it is very good for its age (and it might prove to have been a good investment financially), I am not claiming it can compete with the best Sony or Canon lenses. The same goes for the SP35-80, the nuisance there being that I am sure my hands are less steady than most, so I really appreciate image stabilization. Manual zooms are a problem because every time you zoom in or out, you have to remember to change the focal length setting in the camera, otherwise the stablization may work against you rather than with you (if it is seriously wrong).
