Thank you. They were all shot with Canon gear. I have been shooting Canon since 2003 and went the full route of 10d-20d, 1ds, 5d - 5d IV and 1dx (rented for big trips) through 2016. I purchased the 1dx II & 5d IV when announced and those have been my primary bodies until I purchased the R5 in July. I have always invested in glass with a preference for the flexibility of zooms 24-70 I & II, 70-200 I & II, 100-400 I & II, 1.4x TC II/III, 2x TC II/III (when needed). I had the original 600mm F4, but sold it after 3 years due to the weight (almost 14lbs). The Africa photos are predominately 200-400 f4 L IS w/1.4x TC - rented for the first Africa trip until I purchased a factory refurb at the end of 2016 (great price). I have rented lenses like the 500 & 600 I/II for trips where I knew my owned lenses would not give me enough reach. I would say the quality of the glass has been the most significant contributor to the quality of the images w/ sensor second and the zooms have improved significantly over time. The glass is one of the reasons I have stayed with Canon even when there have been better sensor/body options on the market. I think other vendors have rounded out their glass either natively or 3rd party and Canon doesn't have quite as much edge. I sold my 200-400 because I wanted to reduce weight, but would buy back in for a 200-500(600) f5.6 @ 6lbs (my wish list). I believe the 200-400 w/integrated 1.4x is the most versatile and high quality wildlife/safari lenses on the planet because you are f4 f200-400 and with the flip of switch 280-560 with a max f5.6. I was hoping the 200-400 would get the big white III weight loss program.
