- Geez, you guys, you don't seem to get the point. Yes, of course it does, but
- so do ALL the other lenses. I only chose 8x because it is the largest
- enlargement most people ever have made. I could have chosen 11x14's or
- 16x20's and all the SQFs would have been lower, but the RELATIVE
- performance of the lenses would have been exactly the same, i.e the
- optical quality of the EF75-300 is certainly comparable (and in some
- cases better) than that of the lenses I compared it to.
