I bought this beauty last week but as with most cameras I've been struggling to focus quickly. I came across a suggestion involving using cheap reading glasses and a saw....sounds odd! I had a few pair of broken prescription glasses with ok lenses. Popped out the right lens, covered in masking tape to protect it then cut a 16mm circle where I thought the visual axis was with a dremel and cutting wheel20260316_103532.jpg20260316_085125.jpg. Gently sanded until it snugly fit where my eyepiece ring had sat (this unscrews). Just been out for a few shots and what a delight! Transformed my shooting. I've made a rectangular one for the nikon sp too.
