Having worked in photo retail for over forty years, dealing with all major suppliers of cameras and equipment, puts me in a position to say that of all the companies I deal with, Leica is in a very small group of the most responsive to any real user complaints. No one will likely shed a tear for a Leica owner, but the frustration of not having the camera is real nevertheless. Leica has had my camera since the end of April, and has assured me that I will receive a replacement unit when it becomes available. ![]() For sports and dance, higher shutter speeds are often needed to freeze hands and feet. The LEDs are undoubtedly part of the cause of the problem, and something that photographers should be aware of given the increasing ubiquity of LED technology. Without more extensive testing under controlled lighting conditions, I can’t definitively determine whether the problem is 1) specific to the sensor design, 2) a manufacturing defect, or 3) a case of a specific, dimmed lighting condition that has nothing to do with the camera. I didn’t see the problem on my Nikon Z7 at the same shutter speeds, but I also wasn’t shooting with the Nikon during the exact same scenes and lighting conditions. But the detail of a section lit by sunlight doesn’t exhibit banding. Banding is visible with subjects under LED wash lights. And in another image, I saw that the ambient sunlight wasn’t causing the same banding issue. But LEDs sometimes use a method called Pulse Width Modulation to dim the light, and this can cause “invisible” flicker that shows up in videography or photography.Īs I looked over the metadata of the images with the banding, I noticed that it occurred reliably on the Q2 at 1/2500 and faster, and unpredictably at 1/2000s. LEDs have become extremely popular for continuous lighting because of their low energy consumption and heat generation, making it ideal for use in theatrical lighting. Banding usually manifests itself as a black-and-white shadow, which made my colorized encounter a bit curious. But anyone who’s ever tried to photograph a television is familiar with refresh rates and how it can affect an image. But while shooting in April, I noticed that many of the overhead wash lights were LED-based.įlicker from various light sources is a well-known problem in video, and less known in still photography. Many years ago when I worked in the theater, it was outfitted with halogen-based lighting instruments. The G (and G2) channels have no visible banding, while the red and blue channels have heavy banding.

Of the first 1,000 images that I shot with the Q2, thirteen of the images contained significant banding. I put the camera through the paces while photographing some dance rehearsals at my high school’s theater. But the dust reappeared in a matter of a few days. A temporary remedy was to gently knock the side of the unit with my palm, which seemed to dislodge the dust temporarily. The Q2 addresses the problem with IP52 weather sealing which provides “Protection against solid bodies larger than 1mm” and “Protection against condensation.” The engineers reportedly went to great lengths to add weather sealing while maintaining essentially the same small body size.īut as others have noted, the EVF is prone to dust accumulation, and my unit had dust inside the EVF out of the box. I used black tape to cover up the microphone ports on top of the camera. Since the Q employs a fixed lens, there’s no way to clean the sensor without sending the unit back to Leica’s notoriously slow service center. My major complaint with the Leica Q was the lack dust sealing, which eventually caused me to tape up the microphone and speaker ports to avoid dust on the sensor. While I hope to do a full review of the unit in the future, I had two problems that caused me to send the unit to Leica’s service center within the first month. ![]()
