On Good Friday I had the opportunity to try out some macro photography at the Niagara Falls Butterfly Conservatory with my Nikon D750 and the AF-S Micro 105mm f/2.8G. The conservatory makes for a great day trip for anyone in the area - hundreds of brightly coloured butterflies are constantly flying and feeding, and it's not uncommon for visitors to become a landing-pad for one of these insects.
It's also a great opportunity for photography, especially since the park staff allow flash photography - which will always make macro work easier. This is one advantage I quickly found needed to be leveraged as much as possible. Unlike flowers, which tend to stay fairly still, the butterflies never stay still for long. I composed and shot each of my photos in a matter of seconds, with my SB-700 flash pointed behind me; despite the glass high ceiling, there was enough overhanging foliage to bounce light back. Sadly, action shots weren't possible as 1/200 sec - the D750's sync speed - was nowhere near fast enough to stop motion blur in the wings. Given the limitations, I found the combination of my D750, SB-700 and an AF-S 105mm 2.8G to be more than adequate to create some compelling images. The D750's autofocus was accurate, rarely hunting, and the AF-S 105 was fast to focus.
