I had one of these back in the 90's that I didn't use much and ended up trading it for a zoom of sorts. The other day I was cruising eBay when I ran across one in MINT condition so I bid on it and won. It came yesterday and I am shocked at the build quality of the BUDGET lens. The fit and finish of this lens is as good as anything Zeiss has to offer. All metal, crisp aperture and butter smooth focus. IQ seems good but I really haven't had a chance to test it much. My point is that this lens was marketed as a budget model. Things really aren't built like they use to be. (I feel old).
