|Original Lens:||45mm Pentax 645 lens|
I bought this lens used at B&H Photo. I ended up using it for several shots in New York and it worked really well. However, I ended up returning it to B&H because $300 seemed like two much to spend for a "play" lens, plus the aperture was difficult to adjust on the Pentax.
I regret that decision because I think this was my most successful lens and I can't seem to find another lens that works at that wide of an angle.
I used the same mount as Homemade Lens #3, using the rubber banded plastic allowed me to change lenses without any hassles.
Here are a few sample photos:
