Going super-wide for architecture, environmental portraiture, landscape and astrophotography, well supposedly.
However, I use super-wide lenses for their huge depth of focus and also their ability to create apparent front to back image distortion when used at close distances.
Hence my Voigtländer 15mm f4,5 Super Wide Heliar Asph III VM with its impressive 110 degree angle of view, together with its 15mm optical viewfinder, for use on my Leica M10-R.
When set at f8 and zone focused using the scale on the lens barrel, then everything from 0.5m to infinity is in focus, as can be seen in the top most image of the Gallopers and that of the traction engine above.
The two images above (the traction engine and the Waltzer) illustrate the super-wide "distortion" effect exaggerating the relative size of foreground objects,
As for the conventional thinking about the use of super-wides being constrained to use in architecture, environmental portraiture, landscapes and astrophotography, well in the images above it is being used for none of these things so it just goes to show that convention strangles creativity..
None-the-less super-wides, sometimes referred to as ultra-wides, are specialist lenses that you need to know how to use efficaciously to obtain best creative effects.
