Those of you who have shot 21mm Super Angulon lenses on Leica film cameras may skip this post. Also anyone who has ever owned an 18mm Hologon. You know the drill already.
I discovered the effects of superwide angle shooting at the Burswood Hot Rod Show in 2012. I took the 8-16 Sigma lens into the Burswood Dome on my Nikon D300 and shot away. The images in the viewfinder had straight edges - the 8-16 does not do fisheye distortion. They looked amazing - despite the fact that the lighting was appalling.
A recent review of those pictures horrified me. Every car shot from the front or rear quarter looms out of the picture like a cartoon monster. It is reminiscent of the worst of the old Linhof Chamber Of Horror articles. I got the cars on the sensor in the crowded conditions, but the images are neither attractive nor accurate.
I tried again with the 23mm lens on the Fujifilm X-100 at the Big Al Show this year and was pleased with the results - as the lens replicates what the 35mm lens saw on a film camera, there was much less distortion. Mind you, it was necessary to back off further on the open ground to get the entire car in the frame, and this might have been difficult in a closed venue.
The compromise between the two seems to be a focal length of 18-19 mm on an APSC sensor. It approximates 28mm on a film camera. I can achieve it on the Fujifilm X-E2 with the 18mm f:2 lens or by screwing the WCL-100 to the front of the X-100. There is more to see, but it does not loom out of the picture - a good balance.
And I can agree with Fujifilm - the WCL-100 does not degrade the image of the X-100 lens in any way.
Note: the Bugatti is a deliberate artwork in the Art gallery of NSW. Marvellous, but not driveable, except in your dreams.
