These are some screengrabs from last weekends shoot, a short about a legend/folk tale surrounding the castle I currently work at. Lenses used were 28mm, 35mm, 50mm and 85mm (all Nikkor).
The brevis is a pretty neat adapter, however tacking it to the front of the stock lens made for an impractically long contraption. Light loss was acceptable, but next time I think I´ll try my luck with a letus hd100. There was also a fair bit of vignetting in some shots that was very hard to see in the viewfinder/monitor, fortunately for this project it´s not a bad thing.

I´ve fiddled with some of the grabs (either converting to b&w - some parts will be in silent-film look; or tweaking the colors a little. nothing final, just trying out a few things).
