It's the same 1:2, just a narrower angle of view. John ________________________________________ From: [email protected] [[email protected]] On Behalf Of Patrick Nelson [[email protected]] Sent: 21 April 2009 06:46 To: Pentax MAIL Subject: Macro
Hi I have a question arround the magnification factors on macro lenses. If you use a 1:1 lense on film the image is life size on the negative. What does this translate to on an aps-c size sensor 1.5:1 ?. I use the a100 f4 macro which is 1:2 would this then translate to 0.75:1 or 3 quarters life size. I know that as I am not doing any measurements on the resulting image and use the lense as the size and framing I want it is imaterial. I wouls however like to know. Thanks Patrick ps I have been subscribed for +- 8 years just never really contributed much.
