So you are getting 3% more pixels horizontally when using 3:2 mode, which gives you the wider horizontal format.<br /><br />If you are only interested in the horizontal field of view, then you could say that the crop factor changes from 2x (4:3) to 1.93x in 3:2 mode. This means that the 20mm lens becomes comparableFredrik Gløcknerhttps://www.blogger.com/profile/07523430148487818493noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-52990999635772456662012-11-11T11:39:00.146+00:002012-11-11T11:39:00.146+00:00Is there a simple calculation for understanding th...Is there a simple calculation for understanding the effective focal length when using the multi aspect ratio? As in my example, I feel that the 20mm pancake on my GH1 is a wider focal length when using the 3:2 aspect ratio but I can't work out what it is exactly.

I'd assumed both would give me an equivalent 40mm but they don't and by quite some margin too.Anonymousnoreply@blogger.com
