Super wide heliar test

What apertures did you use? Would be nice to see the difference in vignetting.
Did you use a bubble level or can you guess horizontals/verticals that well?
 
Hi:

Appertures from 5.6 to 11/16, should note them to not forget...

No bubble level, trying to get paralells and, specially last pic, correction with PS.

Thanks
 
Thanks, The reason I asked about the apertures is that I found the vignetting to become less when stopped down.
So you do have a good eye for verticals. I have a tiny bubble level glued to the side of the finder, because it is so hard to align verticals in the barrel-distorted finder.
 
Nice shots Marsopa!

Laptoprob- the suggested apperature for the 15m is 5.6 - suggested by Erwin Puts. The key is to leave it at 5.6, and to compensate shutter.

Another great idea is to shoot the same image using all different aperatures, and evaluating your results.
