I really feel that the expections that people expect from a lens are getting extremely out of hand. I keep seeing people talk about corner sharpness with the lens aperture wide open and general softness at low apertures.
From what I gather this is normally how a lens works. Low lens apertures are almost always going to produce a mostly soft image due to shallow depth of field with a small centeral area being the sharp point. If more sharpness is needed the lens can be stepped down to give the desired effect.
this is how I always thought of lenses. When did it become a need for a lens to be pin sharp right from the lowest aperture. maybe Im just sick of hearing about sharpness all the time but it is only part of what makes a lens great.
