I don't have the best eyesight, I don't have the youngest eyes and I wear progressive lenses in my glasses. I recently purchased the manual focus Nikkor 50 1.2 lens which I love. Focusing is quick and easy for the most part. That said, a sharp focus is everything and under many conditions, focusing with this lens can also be a challenge, possibly given my eyesight.
I started a search for focusing aids and eventually learned about viewfinders, typically used for video, which make focusing easier, like the Z-finder and others.
Again, since not much good happens without having a focus on focus, and since a tripod is not always convenient, what are your experiences with viewfinders? I'm considering the Cinevate Cyclops viewfinder too. Taking video is also in my future but this is more about still photography where a tripod is not used. The viewfinder is bulky but magnifies the screen and also must be used in live view.
Any disadvantages to shooting mostly in live view? Thanks.
