Flickr member David Williams took this wide angle shot of London’s Tower Bridge with his Fuji X-E1 and a Fuji XF 10-24mm f/4 lens opened wide to 10mm (about 15mm in 35mm terms).
What strikes me about this image, besides the fact that it’s a very nice composition of an interesting bridge and set of buildings in London, is that there is no visible barrel distortion on the left and right edges. This is impressive for a very wide angle image with any camera/lens system but I have to say, having owned a Canon 5D and a Canon 16-35mm f/2.8 L lens (a very high end lens) this is even more impressive.
London City Hall (the distorted building on the right) is shaped that way but if it weren’t it would be a tell for barrel distortion.
It’s possible he’s corrected distortion in Lightroom or another image editing program but I’m thinking not. I’ve asked him up on Flickr so we’ll see but I think the lens is very well made and he’s framed the shot perfectly.
