I've been doing some test macro shots lately and it's been a pain to focus sharp. The macro lens already minimizes DoF and makes things hard but I've been thinking of an external screen that I can pan/zoom to check focus quality.
I haven't been able to find much, probably because I don't know the keywords to search for. I hope there is something on the market.
At the moment I'm using the live view and the +/- keys to magnify the live view in order to check the focus quality.
What would be better alternatives considering I will use a tripod?
