There are other factors to consider like resolution, distortion correction, colour rendition, flare resistance, size, weight, build quality, ease of focusing, etc. Not to mention other more subjective criteria like prestige factor, re-sale value, rarity, value for money, warranty, etc..

thats all i'm asking really, if you believe that all of those factors will be high enough to justify the production of such a lens.

contender? dont they already have a bunch, particulary the 18-200 mm?? LOL
