Most people aren't much fussed about what kind of pan their dinner was cooked in, nor should they be. But other cooks are interested. The same is true in photography; mostly only other photographers are interested in the tools that we're using. So this one is for you other photographers.
I'm still using Canon equipment and so far haven't wanted to diversify. This gear is working great, the expense is large enough without getting into other brands as well. I don't have any issues with dynamic range or pixel counts. This equipment provides more capability than my ability to surpass. When the last SLR is made and mirrorless cameras are all we can get, I might just well hang up my photographer's cap and pick another pursuit; the thought of making photography more like a video game makes my heart sad. In the beginning, I shot Olympus, and when they got rid of all their mirrors, I got rid of Olympus (one of the better moves I have made in my long life).
From left to right: The EF 100mm f/2.8L Macro IS USM, The 7D Mark II with Canon grip, the EF 100-400mm f/4.5-5.6L IS II USM, the EF 24-105mm f/4L IS USM, the 5DSr wearing the lovely EF 16-35mm f/4L IS USM and the Canon grip, the EF 70-200mm f/2.8L IS II, a Rokinon 14mm f/2.8 IF ED UMC, a Peleng 8mm f/3.5 circular fisheye, and of course, the EF 50mm f/1.4 USM. In back, my field tripod is a Manfrotto 055CX Pro4 wearing a Sirui K40x head.
Not pictured: a few Yongnuo flashes and wireless triggers, including a Yongnuo macro ring flash which becomes very useful in the spring time, and a full set of extension tubes to make the 100mm macro even more potent.
I like large, heavy cameras with lots to hold onto and little reason to let my hands tremble while shooting. I also like almost never having to think about the batteries until after I am home downloading. So for me, the grips are essential. Bonus: using a portrait grip reminds me to actually try composing in portrait orientation from time to time. This is not something that automatically occurs to most landscape shooters.
I also prefer shooting with an L bracket on my main camera, and one for the 5DS R is on the way.
