    Focusing loup

    Hey guys need some recommendations I'm gathering all my gear I don't have a ground glass focusing loup.

    I wear glasses can somebody recommend a good brand of loup. I've been looking around I'm wondering why some of them are two and a half inches long and some are only an inch long some have diopters some don't.

    The long ones are good to use with cameras that have folding hoods behind the ground glass, and/or for more distance from the ground glass.
    I wear glasses and I use a Toyo/Omega long loupe, 4x magnification...but others will chime in with their preferences.
    You might have to try out a few to see what works best for you.

    If you are nearsighted then a pair of +3.0 reading glasses may be all you need. As to conventional loupes, I have never found one I like. I sometimes carry an old 8x Hastings magnifier.

    I am mildly nearsighted and found the strongest drugstore reading glasses perfect for focusing.

    Well from what I've read I've heard that 4X to 5x is the ideal magnification of a loupe. I don't have anything on the back of my camera so I guess I don't need any long one I can just get a short one I wasn't expecting 50 to $75 for a loupe.

    Many find that a magnification of 5x to 8x works well, but as noted above, there are a host of solutions. Although some find optically poorly corrected magnifiers, such as the bell-bottomed plastic inexpensive ones, sufficient, I would not recommend them, perhaps because I also wear glasses. Although the center area of the ground glass may be easy enough, the edges and corners can become tricky to focus, even with well-corrected optics such as the Toyo or Wista loupes. My personal solution is to reverse the loupe and space it using a finger against the glass, checking for focus on the frosted GG pattern before checking/adjusting image focus.

    A good loupe is a long-term investment. If needed, saving up for one may be a good reason to pinch pennies elsewhere.

    Re: Focusing loup

    Years ago I bought a 9x or 12x loupe from Edmund Optical. It came with a clear base but could be opaque (black) on request. It cost less than the ones from Schneider (8x) but is sharp and I still use it decades later.
