[Commenti] Sigma Art 12-24mm f/4 DG: sixth sense of prospective

 
After our recent preview now we're gonna to explore Sigma 12-24/4 Art expressive power, 
considering this will be one of my first time to measure myself with a so extreme wide zoom: I strongly prefer prime wideangle instead zoom, also if in other time we were forced by "APS-C factor" to try every focal lens to rebuilt a 20mm angle coverage also with zoom ...simply born to other uses...
 
This Sigma Art cover on full-format an immense range of field of view: since 84° to 120°, from few less than a right angle, to a third of a full circle !
This means that differences between onlight/backlight are really thin...
