Rangefinders can focus very accurately under most conditions, but unlike auto-focus cameras, put a greater demand on your own eyesight being good. If you wear contacts it's not a big deal - but what about eyeglasses? Let's be honest, it's a pain to shoot with glasses. So what options are there? Frankly, up until a short while ago - not much!
Enter the Walter RX Eyepiece - a custom designed eyepiece attachment that fully corrects for your vision specifically. In fact, it's so specific that you need to know your prescription when ordering one. A custom lens is then made and fitted. This eliminates the need for any diopter correction and may even eliminate the need for viewfinder magnifiers. More importantly, there's no longer a need to wear glasses while shooting!
