I am very frustrated by the fact that I can never seem to get my focus right on my Bolex H16 Rex (1) with a Kern Switar 25mm RX... or really any lens.
This is a really big problem indoors when the viewfinder is just WAY too dark. I can't see the image well enough to focus it.
My focus is fantastic if I physically use a tape measure to measure the distance from subject to film plane mark. But, I can't do that on the fly, bouncing around, primarily chasing my 20 month old son for home movies.
Any advice on dealing with this problem is greatly appreciated. Are there add-on range finders, hand-held laser rangefinders, etc that I should try? I am clearly NOT going to be able to use the reflex viewfinder for anything other than framing.
Thanks in advance... especially for offers to sell or links to purchase necessary equipment.
