- Regarding the two Canon EF lenses that you cited, part of that expense
- should also be attributed to the fact that the EF 80-200/f2.8 L has a constant
- aperture through all focal lengths, where as the EF 50-200/f3.5-4.5 L has
- a variable aperture. That little feature adds a nice chunk to cost of production,
- in addition to the extra stop.
-
- As a personal choice, I prefer constant aperture lenses.
