Holga HL-N Nikon DSLR Lens

So I bought myself a Holga HL-N lens recently and it’s been fixed to my old D40 ever since. Because of the fixed aperture it’s extremely hard to shoot with (particularily indoors) as the view finder is extremely dark, it’s supposedly fixed at f8, but given how dark it is and the deep depth of field I would say it’s actually more like f11. However, some of the photos I have taken with it are pretty cool. The results simply couldn’t be reproduced in photoshop, massive light streaks and really over saturated colours. Pretty cool.
