Full frame or crop sensor DSLR?
This is a key decision because the choice affects some of the most important aspects of close up photography. To understand this, it’s worth considering the technical requirements that are needed for successful insect photography. Basically, we’re talking about three things: approaching the subject without frightening it, getting it in focus quickly, then shooting a photograph of high image quality. The crop sensor camera has the edge for the first two requirements and it’s probably a dead heat for the last. Here’s why… Leaving aside field craft, approaching the subject successfully is all about working distance, because the further away you are from the subject, the less likely you are to scare it.
