If shooting at f/22, is a fast 1.8 lens still considered fast?

Re: And Wikipedia is wrong in this regard

exactly how I feel - more light = more contrast - but you refuse to hear it

and what exactly makes Marianne Oelund more of an expert on this subject that the people at lensRental.com and Canon?

did you even read the article I posted from lensrental.com? frankly I will take their technical explanations over yours if for no other reason than they backed theirs up with references from 14 other sources.

the best you can come up with is some one named Marianne and an abstract by some guy named Doug Kerr

sorry that doesn't cut it - not when the manufactures themselves disagree

I don't know what more I could do to explain this to you when you are apparently so stubborn to not even be willing to consider the meaning of 'correlation is not causation' and seem far from going as far as making an honest effort in understanding the technical explanations I have linked to including the very practical ones by Marianne Oelund.
