At the beginning of January I'm headed to: Istanbul/Cappadocia Zanzibar Serengeti and surrounding national parks for safari Virunga National Park in the DR Congo - gorilla trekking and Nyriagongo volcano Nairobi and potentially a few parks near there - Amboseli, Hell's Gate, Tsavo East Mombassa, Watamu and Diani beaches I'll be shooting lifestyle/culture, surf, SUP and kitesurfing, and safari wildlife. Photos and extensive video. Will be using the E-M1 mark II and the GM5 and taking along a DJI Mavic and a few GoPros as well. I'd like to minimize the lenses I'm bringing and would love everyone's views on what I should bring. Here's what I have: PL 100-400mm f4-5.6 Oly 40-150mm f2.8 + 1.4x TC Oly 75mm f1.8 Oly 12-40mm f2.8 PL 15mm f1.7 Samyang 12mm f2.0 Samyang 7.5mm f3.5 fisheye I am also potentially borrowing an Oly 7-14mm f2.8 from a friend as I don't have anything ultra-wide landscapes and high-res mode shooting. So lots of lenses. I'm thinking about ditching the 40-150mm and taking the 100-400mm. The thing is I just got the 100-400mm and have never used it before. Only familiar with the 40-150mm. Also thinking of keeping the 12mm at home although I would have liked it for astro stuff. The 15mm is good being paired with the GM5 and for low light/low weight kit on evenings out and street. The 75mm is also good with the GM5 for the same thing. Would love to see what people think! I always over pack. I feel like I would be fine with just the 12-40, 100-400, and the 15mm and 75mm. I'll be packing it all in the Peak Design Everyday Backpack 30L. I could bring a small messenger bag as well.
