For this shoot, I rented Fujifilm's 56 mm f/1.2 lens. This lens has gathered quite a reputation: it's supposedly endowed with an unbeatable combination of build quality, sharpness, and sublime creaminess in the out-of-focus areas. I just had to find out for myself.
Paired with my old but trusty Fujifilm X-Pro1 camera, I shot three models in a studio. I used a 3-light setup. The key light was set above the model and was either pointed directly at the model's face or bounced off a white umbrella. The hair light was set slightly behind the model, gelled blue, and flagged so as to not shine into the lens. The background was painted white, and I lit it with a red-gelled strobe. Finally, I set a silver bounce at the model's waist level to fill in the shadows under her chin. Exposure was around f/5.6 at ISO 200. I shot JPGs, and set white balance off my X-Rite ColorChecker Passport.
These are straight JPGs from the camera, with no more than a 1/3-stop adjustment to exposure. All i can say is "Wow!" The images from this camera/lens combo are simply divine, and I'm very tempted to make this lens a permanent part of my toolkit.
