Jan 6, 2014 at 11:50 comment added Matt Grum @KartickVaddadi It's the same for all lenses, wide and telephoto - making the aperture smaller is never a problem, it's just a piece of metal blocking the light path, it's inclusion does not compromise the design in any meaningful way, yet it's inclusion makes the lens much much more flexible.
Jan 6, 2014 at 11:37 comment added Kartick Vaddadi Okay, so leaving wide apertures aside, would it be possible to make an ultra-wide fixed aperture lens for far less cheaper than variable aperture lenses? What about telephoto lenses (other than mirror lenses)? Or is it the case that no matter what the fixed aperture is, and no matter the focal length and other factors, fixed aperture lenses just don't save enough money or give us other desirable qualities to be worthwhile?
