I was instantly fascinated by its exposure value calculation system which compensates for its lack of variable shutter speed. As you can see in the photos above, gauging the right focus distance isn’t easy at all. And a guesstimate of distance is the best measure you have of what’s going to be in focus in any given frame without pacing off the distance.
All these images were taken with Efke KB100 black & white film, developed in Kodak HC-110E (1:49 mixture) for 7 minutes at 69°F. I scanned them with an Epson Perfection V600 scanner. Photoshop work included minor dust removal from scanning using the content-aware (seems to help preserve natural film grain while removing unwanted dust) clone stamp and healing brush tools, and slight exposure adjustments on some frames using a levels adjustment layer.
I used the exposure values for Kodak Plus-X film listed on the camera’s EV chart, and the exposures came out very well, with a few being just very slightly over-exposed. Plus-X has an ISO of about 80, roughly half a stop slower than my KB100, so it was no surprise that some of my pictures were 1/3 or 2/3 over. Fortunately the Efke is very forgiving film with medium-to-high contrast and fine or very fine grain, and high edge sharpness due to its classic grain and high silver content. The overexposure was very easy to correct for with minimal adjustment and yielded good contrast in the finished images while preserving detail quite well in the shadows.
