I'm having a hard time seeing the screen well enough to focus with my Rolleiflex 3.5E. I've got a Maxwell screen. I've got bifocal glasses. I find the pop up magnifier doesn't help much. On a tripod I can use my cheap 5x Peak magnifier and focus fine, but handheld it's hunt and peck and hope for the best.

Any tips on how to magnify the focusing screen, for handheld work?

Thanks,
