1. UV filter
Ultra-telephoto zoom lenses such as the Nikon 200-500 mm and Tamron 150-600 mm take 95 mm filters. I love the NiSi 95 mm UV filter, however many Tamron users have complained that it doesn’t fit well on the 150-600 mm lens.
Hoya also make 95 mm UV filters.
The Canon 100-400 lenses take 77 mm UV filters.
For more information about UV filters, please read my blog post, “5 accessories that you must purchase along with your DSLR camera”.
3. Manfrotto 393 Gimbal Head
I love the Manfrotto 393. I use it on my 679B monopod. This all-metal gimbal head has a load capacity of 20 kg.
4. High-speed SD card
I have no words to express the importance of high-speed cards for wildlife photography.
To cut a long story short, I like the Sandisk Extreme Pro 95 MB/s 64 GB SD card.
Please read my blog post, “The best SD card for me” for other options.
5. Lowepro AW 450
The Lowepro AW 450 accommodates lenses such as the 100-400 mm, 200-500 mm and 150-600 mm.
It has a dedicated laptop compartment.
