@matthere : I can't afford this one ;) @robmneilson : I was thinking the same about small spaces, that's the main reason why I decided to invest in a new lens. But I fear I won't be using it a lot compared to the Voigtlander.
Give me your advices ! ;)
@krotal you could also look at the wider Voigtlander at 17.5mm it may help your dilemma :)
It all really depends on what you shot. For example on much of the paid work that I get the Tokina might be used a fair bit since we're always crammed in a small space and the client wants a wide shot, but for my personal work the Nokton would be used much much more.
