Maybe is lite strange question and i have discuss this before with some friends but her we go again
Untill now I have use a lite dome port with my 10.5mm & 16mm
I have done maybe something stupid and sould my 16mm Lens
Now i have a 170 dome and i use the 10,5 & a tokina 12-24
Offen i think that i miss the 16mm lens. No offens 12-24 is great but behind a dome i think a fisheye fast lens will perform better that a WA zoom
I hope to get more contast, high quality and better corners in the same time more light in the lens
But i am not sure.. I shoot mostly human full & halvbody portraits. and if the posing and body fell the frame maybe a fisheye behind a dome is a better solution
