I relatively new to Leicas and rangefinders, I used my friends M9 for about a week before buying an M-E, so I'm still getting used to learning how to focus. I only have two lenses, 50 summilux and the 28 elmarit, and I'm considering getting one of the magnifiers to help improve my focusing with the 50. From what I've read online it seems that the magnifiers are normally used for FL at around 50 and greater, so I'd probably need to take it off when using the 28 or pick up a viewfinder. How hard is it to take the magnifier on and off? Does it make sense to remove it when using the 28 or should I pony up and get a viewfinder to go with the 28 so that I can leave the magnifier on all the time? I'm more inclined to just pick up a viewfinder for the 28 so that I can leave the magnifier on as I'll pick up some longer lenses when I have a need / money. Also I wear glasses all the time and I read conflicting information about users with glasses and the magnifier. Will there be any issues with the magnifier if I'm wearing glasses? Any input is greatly appreciated.
