I remember the Olympus E1. It had a non interchangeable but very good quality zoom lens. The above softball photo was made with the 70 to 200 F / 2.8 VR,(@ 175mm at f/4 at ISO 640 ) the first one, the lens that was so good on low to medium resolution DX sensors. That lens had quite a skinny barrel, and was amazing on DX... but it was not that good once we hit 24 megapixels on full frame. Even stopped down to F 7.1 on the 24-megapixel D3x, the corners showed softening, and after about sixteen years of good service,I was forced to sell it. I paid $1,695 for it the very week it was released, and after 16 years I got $1,000 from selling it. The lens was really amazing for its time, but the skinny barrel was not up to the task of covering full-frame.
To replace this 70 to 200 I bought the fairly uncommon 80-200 f/ 2.8 AF - S, which had been designed for film, and which performed much better on a larger sensor.
