I want to put a Nikon camera on a microscope and be able to connect the HDMI socket directly to a monitor in order to see the image without any delay and this is essential for focussing the microscope and other purposes. I am told that no Olympus camera can do this (by their technical section) but I have heard that it can be done, even with the relatively low-cost Nikon D3100. Can anyone confirm this? Recording first to a card and then playing back after a delay is useless for this application. It is important to be able to do this e.g. for schools, to show the pupils the higher-than-video resolution image: normal PAL or NTSC video is capable of capturing only a tiny area of the eyepiece view in a microscope without losing information.
