I mean firing them isn't any harder than blued guns, and the cleanup's easier, but shooting them with a camera is a pain.
Here's the first try with the Model 59, from back when I first got it in October of 2019.
I was using the EOS 40D with the EF 50mm f/1.4, shooting wide open like an idiot. That caused its own problem because the depth of field is so shallow with an aperture that big, even on an APS-C sensor. Notice how the hammer spur is out of focus? Yeah...
Anyway, with where the pistol was sitting on the patio pavers, the colors of the house are visibly reflected in the slide.
A few months later in May of Cursed 2020, I took another crack at it, this time with the Nikon D3000 and Nikon 35mm f/1.8 combination.
Mindful of the issues with the previous shot, I was more careful to get enough depth of field and carefully positioned the pistol on the patio so it wouldn't be reflecting the house... and instead managed to capture my own reflection in the slide.
Yesterday morning's attempt was with the 5DS and EF 24-105mm f/4L. This time I stood well back and shot at 105mm, from an angle that showed no reflections in the pistol, and I had a high, thin overcast providing a soft and even light since the morning sun hadn't burned it off yet. I think this is about as good as I'm going to get with available light and no reflectors or other aids.
