You could use the same argument to say that an image made on ASA25 film is not the same magnification as an image made on ASA1600 film. It's not relevant.

You are right that it doesn't make much sense to compare the images you suggest, though. It's just a different issue. > > From: Mishka <[EMAIL PROTECTED]> > Date: 2007/03/15 Thu AM 02:39:12 GMT > To: "Pentax-Discuss Mail List" <[email protected]> > Subject: Re: Macro Lenses > > magnification on a digital sensor is a moot point anyway. > how do you measure it? > suppose you have 24x36mm (FF) sensors: one is 2x2 pixels > and one is 20MP. does it make any sense to compare 1:1 mag > images made on them? > > best, > mishka > > On 3/14/07, John Whittingham <[EMAIL PROTECTED]> wrote: > > > > But you still have to be at the same distance to achieve 1:1 or 1:2 as the > > case may be, fact!
