Thank you very much for your answers

It really help me and more with comparisons of the different Smc 28mm
The choice is so so hard. Maybe I will take Smc k 28mm f3.5 because it will be the safest in time to be happy. I think that if i take a Kiron it will be the A one to not have mechanical problems but the price of the bargain is same of te Smc ...
But maybe the smc F 28mm f2.8 but seem to be less under ...
On the photos of Wild Mark, the differences are at the same time not important and ... important with a long utilization ... but depend also of the photographer lol
Do the smc k 30mm f2.8 is up to its reputation and can represent an alternative to k 28 f2 ? or k28f3.5 ?
Thank you very much again.
