A Weekend Of Discovery
Round one. Read the label. Whether you are mixing a cake or setting a camera or purchasing bookcases from IKEA...read the label. Saves you hauling three giant cardboard boxes back up the freeway in a Suzuki Swift to exchange them for one of the right size.
Round two. Hook up a mirrorless camera to the studio lighting system and try to use it in the same way that the DSLR system operates. In my case I have an adapter that lets me use the same lenses as my Nikon. Oh boy, I bet it is going to be better...! Oh boy, am I wrong.
The lenses and the sensors being equal...the images are the same size and proportion. And the depth of field is the same - thats a function of focus distance, focal length, and aperture.
No gain there.
When I am using a camera in studio mode - manual setting for both aperture and shutter speed - DSLR's let me see through the viewfinder at full aperture and then check depth of field by pressing a preview button. Mirrorless cameras don't - they compel me to open and close the aperture by the click-stop ring and I am liable to push the whole assembly out of position as I do it. Do-able, but much more inconvenient.
Moral of the story? Use the regular heavy old DSLR for studio work in manual mode. Save the new you-beaut mirrorless for convenient field shooting.
Round three. The new you-beaut mirrorless camera can be mounted in a wooden box and triggered with a standard cable release. It is absolutely soundless when in the box, but will do perfect automatic focussing and exposure. It will also do a pretty good recording in sepia straight out of the camera. Steampunk Time!
