Even so, there's nothing difficult about the claim. He says it is sharp wide open. That has to be a pro, because it's not true for many lenses. But it is even sharper at 5.6-8 - that's normal for most lenses. It is certainly not true that at f/8 all lenses are created equal. However, if you believe they are then I will happily sell you any number of Sigma lenses for slightly less than you'd pay for the equivalent Carl Zeiss versions. -- Bob > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Kostas Kavoussanakis > Sent: 17 January 2007 11:05 > To: Pentax-Discuss Mail List > Subject: Re: It Arrived! > > On Wed, 17 Jan 2007, Patrick Genovese wrote: > > > Pros: > > Sharp... even wide open though it is not at its best.. > by f5.6 -> > > f8 its tack sharp > > Sorry, I am struggling to understand this statement as a pro.
