We've had several (well, more than several actually) threads about which lenses to take on a trip to Africa or Costa Rica and as I've now been to both I thought I would offer up my focal length statistics for posterity in case anyone was interested. Actually…this started out as a question to myself whether what I took to both places (100-400, 600PF, and TCs) was the correct option or whether taking the 180-600 instead of the 100-400 since it is generally rated better and adding in the 24-120 for anything too close for 180. I was surprised by the statistical results and haven't actually made up my mind what to do next August for Botswana yet…there is a 55 pound weight limit there so packing light is more necessary and I'm not sure if the 3 lens carry won't cause issues.
Anyways…here's what I found on Steve workshops to both Serengeti and Costa Rica and I'm guessing that focal length wise Botswana won't be considerably different…if somebody's been both places and that guess is wrong feel free to chime in and say so. Note, percentages for the various lenses are percent of that lens use, not of the total images.
Africa
Total images 31,118 of which 19,358 or 62% were with the 600PF and 10,620 or 35% were with the 100-400.
The 600PF images consisted of 107 (0.6%) with the 2x TC, 14,628 (76%) with the 1.4, and 4,623 (24%) with the bare lens. This tells me that if weight becomes and issue then the 2.0TC can be left behind although IQ wise it's plenty fine with this lens for my purposes.
The 100-400 images consisted of 10,620 (98%)with the bare lens33 (0.3%) with the 2xTC and 135 (2%) with the 1.4TC. Of note the 10,620 total 1,704 were less than 180mm and 1,230 were less than 150mm although to be honest very few of that 1704 would have been seriously impacted if I shot them with the 180-600…a quick estimate is that maybe a couple of hundred would have been. This tells me that from a focal length used taking the 180-600 and 24-120 for close range shots (in addition to my iPhone 15 Pro Max) would suffice if weight in Botswana allows.
24-120 102 images
iPhone 336 images.
Costa Rica
18,639 total images…13,022 (63%) with the 600PF, 4,269 (23%) with the 100-400 and the remaining 929 (5%) with a 105 macro that Dennis Valverde loaned me.
600PF images 11,736 (90%) with the bare lens and the remaining 1,286 with the 1.4 TC.
100-400 all 4,269 images without the TC, 568 (13%) less than 180 and again most of that 568 would have been possible at 180. There were 240 at 150mm or less.
24-70 19 images.
iPhone 130 images.
Taking the short zoom gives me a focal length coverage of 100-400, 600, and 840. Taking the long zoom gives me 24-120, 180-600 and 840 as in that case the 600PF would likely be pretty much married to the TC full time.
Weight wise the shorter zoom total weight is 10.8 pounds and the long zoom total is 13.8 pounds so an additional 3 pounds for what better focal length coverage albeit at the cost of needing to swap lenses if the 24-120 was needed. The 24-200 would save 3 ounces and provide coverage 24-600 and 840 but it's not as good a lens as the 24-120 and DX mode or cropping will cover the missing 120-180 gap making the 3 ounce gain not worth the cost in sharpness and aperture. Likewise…I could take the 24-70 instead of the 24-120 but that only saves 5 ounces so probably not really a viable option. And alternatively I could just use iPhone for everything that can't fit into a 180mm length since there weren't all that many images. The 2xTC will probably stay home unless there's extra unused weight since it didn't get used much (140 out of the total 49,500 images)
At this point…I have no idea which of the two telephoto zooms I will take next August…I'll have to figure out the weight of everything including clothes, laptop, chargers and whatnot before figuring out whether I can afford the extra 3 pounds for the 180-600 but I would put that option slightly ahead of the 100-400 at this point.
