Equipment To Take
I would try and take a good tripod or monopod with a gimbal head if you have it, although I didn’t often use it, even though my telephoto lens is heavy I still prefer to use it hand held as I find it quicker so it will just depend on your own preference. If your interested in landscape images I would still recommend a telephoto lens such as the Nikon 70-200mm as a lot of the landscapes are so vast you might want to zoom in on various sections. Obviously take a wider angle lens as well like the Nikon 24-70mm which you will use when your on land. For the wildlife the bigger the lens the better. I use a Nikon 300mm with a TC giving me about 510mm. Even that doesn’t always get you close enough though. I would also recommend polarising filters for all your lenses as there is 24hr sunlight during the summer and this can create a lot of glare at certain times of day. A good supply of batteries is essential because the cold weather will drain your battery life sometimes within 4 or 5 hours.
