12mm vs 14mm

This is a comparison of the Olympus 12-60mm lens with the 14-54mm lens both at their widest. Many people ask how much more width do you get for what seems like a tiny 2mm of focal length, but this photo shows that 2mm is a lot.


This photo is only across a living room, so maybe 14 feet. The extra width is even more dramatic when shooting scenes further away.


I made this photo by taking the 12-60mm and making it black & white. Then I cut and pasted the 14-54mm shot onto it and resized it down to match. So this is actually two photos one on top of the other rather than me just estimating it in one shot with a color box.


Jan 21, 2010: Note that the fish aquarium is a standard 30-gallon and is 3-feet long. Perhaps that will help give people a sense of scale.


Also one other note. When using the internal flash with either of these two lenses, you will get a shadow on the bottom part of the photo as the lens blocks the light. While it is worse on the 12-60mm than the 14-54mm, most people incorrectly think it is because the 12-60mm is a bigger lens. While this certainly attributes to more shadow a slight bit, the main reason the shadow is so much larger in the 12mm shot than a 14mm shot is because the field of view towards one's feet is much bigger (see above) and therefore it isn't so much that you create a larger shadow, but simply that the 12mm focal length shows more of it while at 14mm you get some cropped out (hidden).
