The 2.8 lenses may be only 2/3 stop faster than the f3.5 but that difference alone would mitigate against using just the K 28 3.5 under many circumstances. I might use it outside in relatively bright conditions, but all the inherent sharpness in the world won't make up for a misfocused image due to a too dark viewfinder. I do that enough with fast lenses...
