I just got the Holga brand wide angle (0.5x) and tele (2.5x) lenses. They just slide over the existing lens. I've seen some shots taken with them, and I like the results, but I am wondering if anyone here has tested them. I am mostly curious if I can focus the same or if I need to modify my focusing technique. I know that when I use diopters, I always put it to infinity.
Anyone use these? Tips? Thanks!
