With inter-changeable lens cameras and especially zoom lenses we can now shoot an image at virtually any focal length we choose without too much trouble. However, despite all this choice I think that there is a tendency to hover around a particular focal length that you feel the most comfortable with. It's something I've never really thought too much about before but having recently gone through a variety of my photos from the last three years or so I've realised that a lot tend to be in the range of 28-35mm (I'm using full-frame equivalent focal lengths). If I had to pick one focal length it would be 32mm. This number doesn't just come from the average of 28 and 35mm, but instead from years of maxxing out my beloved Sigma 10-20mm on Canon DSLRs. 20 x 1.6 (Canon APS-C factor) = 32mm. On my E-P1 the M Zuiko 17/2.8 is a favourite because it provides a similar field-of-view at 17 x 2 = 34mm. Not quite as wide but the difference is not something you would lose too much sleep over. However, Panasonic, Olympus, a nice high-quality non-pancake 16/2 would be greatly appreciated This focal length is just right for me because it is wide enough to take in broader scenes, but not too wide so that you start to lose smaller details. It is also great for those perspective shots that quickly recede away to a vanishing point. The image below is (I think) a good example of 32-ness, taken with a Canon 50D + EF 20mm f2.8. <a href="http://www.flickr.com/photos/55915417@N08/5567581130/" title="IMG_2919-PPR2 Canon EOS 50D Brisbane - Street by Lucky.penguin, on Flickr"> View attachment 164585 "426" height="640" alt="IMG_2919-PPR2 Canon EOS 50D Brisbane - Street"></a> I get the feeling that the answer to this question might be influenced somewhat by the Panny 20/1.7, however it would still be cool to know what it is about that focal length (as opposed to the lens) that you like. Also, has there been a particular lens that has changed you favoured focal length (again, this may be the 20/1.7)? Please feel free to add an image that you think defines your FFL (favourite focal length). Please also remember to define what format you are relating the focal length to as I am really talking about the angle-of-view that a lens provides. 20mm on m4/3 is specific. 20mm alone is ambiguous.
