Current kit: Canon EOS-1 DX, Canon EOS 5D Mark IV I used an OM- D E- M1 Mark II, initially fitted with the M. Zuiko 12- 40 f/2.8 lens, which I was a little worried about as I usually like a longer focal length. But to my surprise I used it for a good part of the afternoon.
I also used the M. Zuiko 12100mm f/4, which is much more similar to the focal length I work with, and found it to be a fantastic lens. Compared with my Canon EOS 5D Mark IV and 70-200 f/2.8 lens, the weight saving is considerable and the image quality doesn’t seem to suffer at all. I managed to try the M. Zuiko 300mm f/4 too, which I also thought was fantastic and much lighter than my Canon equivalent. It was my favourite lens of the day, although it is a difficult choice between that and the 12-100mm f/4.
