Shannon, I use a Fuji loupe that I got "free" in exchange for film box ends. The key is that it is long and has a soft end to go on the glass and the sides are not transparent. Kind of like this Chinese one on eBay item 330108358314. There are three of the Schneider 4x ones on eBay under "lupe" and they have a convertible end but are kind of short.
