28 was first wideangle lens I had long time ago, and quickly concluded the same. Boring. ;-)
Is it not horses for courses?
Taken yesterday, the lowly AF28mm F2.8D just got me to the right distance from the scene, held level the perspective distortion is not evident.
Hoping to take the scene again today with someone in there!
I must be getting things wrong then as I've been shooting 28 and 85mm (AF 85 1.8D) a lot lately .......
....and loving it
As far as primes are concerned - my PERSONAL sweet spots are ... (in FF terms)
18 - 21 - 35 - 85
All the rest ... well ... not for me.
