Excusing the entire fact that the EF-S form factor is an attempt to create affordable lenses.
Also, dude, can you provide some Canon literature saying that point of the EF-S form factor is to be affordable? I thought that the point of EF-S was to market lenses with a Short backfocus design, providing users of crop cameras lenses that are appropriate for the smaller sensor. EF-S lenses cover focal ranges that EF lenses do not, and with any degree of practicality CAN NOT, because they have to cover a full frame sensor.
Here's the Wikipedia entry for Canon EF-S, which describes the mount: "The proximity of the rear element to the image sensor greatly enhances the possibilities for wide angle and very wide angle lenses, enabling them to be made smaller, lighter (containing less glass), faster (larger aperture) and less expensive."
Emphasis is mine, because that's exactly what I'm asking for here.
There are plenty of cheap EF lenses. Many of them are out of production now. There is no reason why an EF lens cannot be cheap. If the only reason for EF-S was to be "affordable," why would they have not just continued making cheap EF lenses?
