Nobody said it wasnt "doable", I said its not as easy as wide open would be for focus/composition and that the entire SLR camara industry adopted autoaperture lenses over 40 years ago because of this.
Secondly I pointed out that if you use fast lenses, you cannot practically stay within only 2 stops of wide open in daylight situations. The faster your lenses are, the more often you are going to need to stop down more than two stops. These two statements of his are contradictory and the whole contention is silly, Any camera system that disables/does not support the auto aperture function of a lens is nowhere near as user freindly to real photography as one that doesnt. This is far worse than the GB with KM lens kluge because at least that only affects metering and AE, lack of autoaperture affects/degrades everything you shoot all the time unless you have the lens set to wide open anyway which is seldom. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Robb Sent: Thursday, February 15, 2007 9:29 AM To: Pentax-Discuss Mail List Subject: Re: Pentax K 28mm f2.0 Lens From: Adam Maas Wed, 14 Feb 2007 12:52:47 -0800 >You don't agree, that's nice. >It works for me. Note also (as per our last go 'round on the subject of >open-aperture metering) that I'm rarely shooting more than 2 stops down >from wide open. And I shoot with fast lenses. It seems to me that shooting a fast lens stopped down a couple of stops would give a similar viewfinder brightness as using a zoom lens wide open, but you would have the benefit of a generally higher contrast image to work with. I can't believe people can't figure this out and choose to argue about it instead, since we've been manually focusing zoom lenses in the f/4-f/5.6 maximum aperture range for a couple of decades. Obviously, it's doable.
