Aperture stop down failure with Samyang 12mm fisheye
Does any of you use Samyang 12mm fisheye? On tuesday I was shooting star trails @ -11C temp and after 128 frames I stopped shooting for few minutes to adjust lighting for few foreground items. After I took the final few exposures I noticed that light levels were way off in the last few photos. The lens was not stopped down to f/6.3 like for the first series of exposures but was left wide open no matter what aperture I dialed in.
These Samyang K-mount lenses have A-lens functionality for automatic aperture setting by camera body. So, which is going now? Aperture actuation lever of K-1 or the Samyang?
