Back when I still had a full Canon DSLR outfit I owned several prime lenses as well as two Canon brand zooms, the 24 to 105 F4 L USM, and the 70 to 200 F / 2.8 L IS USM. My Canon prime lenses were the 50 mm F / 1.8 the 50mm F/1.4, the 85 m m f 1.8, the 100 mm f/2.8 EF macro oh, the second version, with internal focusing, and both the 135mm f/2.8 variable soft-focus lens, which is actually extremely Sharp which shot at the neutral setting with no soft focus effect dial dialed in oh, and also cannons somewhat legendary 135 mm f/2 L. Even though the 135 millimeter F2 is a quote legendary prime lens telephoto I usually found that the zoom tele performed so well that there was absolutely no need to use the prime lens.
On the other hand Nikon's very large and heavy 200 mm f / 2 VR lens, which I bought in 2006 or 7 and which weighed about 7 lb. Was a somewhat better performer than either my Canon or my Nikon 70 to 200 mm zoom lenses... however we are talking about a lens that is priced at somewhere around 4 to $5,000 depending on age of lens and version.
Comparing the Nikon 70 to 300 mm f/4.5~5.6 VR, which was priced at around $589 when brand new against the 300 F 2.8AFS Mark II when the zoom lens was shot at 300 mm it was obvious that the 7 pound $4,900 lens was the better performer However that did not stop me from making literally thousands of perfectly good photos with the lighter and smaller and much less costly lens.
