EOS RP & Sigma 35mm f/1.4 ART Black Circles Issue

 

 When I mounted my beloved Sigma 35mm f/1.4 ART to EOS RP, it shocked me with two black circles on screen and the actual taken photos. I remembered someone asked this question in a forum about EOS-M and Sigma lenses. The problem causing this was Canon's software lens correction feature. If you had the same "shocking" issue and Google brought you here, you can follow the steps below to fix it.

My New Stage Of Leisure M4/3 Life

As many people know, we've been working with Canon DSLR for 12 years. In leisure time, we use Olympus OM-D (E-M1 & E-M5) for travel and daily life. Full frame camera users get use to noise-free photos and very low noise in night photos. I feel M4/3's ISO performance is annoying in these years. Recently, I looked at some samples from Japanese Olympus website. There was a photographer shooting black and white photos in high ISO. The thick noise dots became part of the photos. It inspired me a lot. Now, I start to ignore the limitation and push ISO over 1600. I try to use OM-D like I have 5D3 or A7 III in hand. As long as photos are not for my clients, I just shoot my photos without considering the camera's limitation. I think the fun from m4/3 camera is even more than my work cameras.
