Hey! Thanks for the question.
I use a Fujifilm XT-2 at the moment, and this was shot on the stock 18-55 lens.
The fields usually do snow over for a while. But as soon as it gets a little warmer, the snow starts to melt, become compact, then freeze over. This is what creates the layer of ice on the fields!
Look out for more posts of the Canadian winter coming soon :)
