I have a f/2.8 21mm Minolta Rokkor lens, manual focus - it has darkened corners due to the 1/(cos(theta)**4) loss

. Usable for getting the interior of buildings, especially small rooms by shooting from the corner. Also good for outdoor use because I can have something very close in focus with the scene further back. I used it for overall scenes, but the individual objects appear really small. I do not use this camera any more, but I did use the lens a far amount. The f/2.8 lens looks like a headlight - great for available level light photographs.
I now have a 20mm to 35mm Nikon AF Zoom that I have found much more useful. It does
NOT have the darkened corners due to the 1/(cos(theta)**4) loss

. The zoom capability makes the lens easier to use than the fixed focus [even more than one would think]. Both lenses have to be used carefully when shooting buildings [anything with vertical lines] because the wide angle makes the buildings appear to lean back. Therefore, care must be used to hold the camera level. Again an object that you want emphasized in the foreground is great. DOF is great. Overall landscapes and buildings come out better than the Minolta lens.
I am much happier with the Nikon 20mm - 35mm lens than the 21mm lens due to the flexibility and better optics. I carry the Nikon lens with me when weight is not a constraint. If weight is going to be a problem I use my f/3.6 28mm - 300mm zoom because the wide zoom is heavier than the camera plus the 28mm - 300mm lens.
As far as using the lens for 11x14, I do not know. I have only used it for 4"X6",12"X18" and 24"x36" prints.
I would recommend buying the 20mm lens for 35mm photography. I would suggest, if possible, renting the lens for several days with the understanding that if you buy the lens the rental money gets credited to the lens purchase.
