I think this would be a good choice.
Originally posted by cahudson42 Even at ISO 800 and 1/1250 you can see image distortion in the vertical shutters due to the 1/13 effect (I think) SR focal length set to 170mm. Everything wide-open at f4.
Wow I have never noticed shutter distortion like this on a stationary subject. (But then I don't tend to shoot buildings etc)
I was just able to recreate this by winding up the iso to get the shutter speed really fast (+1/1000) and then by flailing the camera around I could bend lines.
You must have been shaking like hell ca

AAAhhhh just worked out what you mean-- naa I set the SR input to the lens FL-- I have noticed that people are varying it but there has been no emphatic result.
This is another use for your lens test image cahudson -- to get some objectivity here.
