Getting Older - Chapter Two

Jan 05, 2021 · 2 Minute Read

Over the past year or two I've noticed that whenever I open up my large format lenses to compose and focus, the ground glass is quite dark, especially around the edges. While the two I use the most: the Super Angulon 90mm F8 and the Caltar 11-N 75mm F6.8 aren't very fast lenses, it has to be my eyesite as I didn't have this problem in the past.

My first thought was to sell these and invest in two faster minimum, a wider F5.6 for both but while on a zoom meeting with a group of fabulous photograhers from across the US, several brought up buying and installing a bright fresnel lens screen to the back of my ground glass.

Instead of going through the whole process of selling my lenses and finding appropriate replacements and spending quite a bit more money, this route seemed simpler. Fabulous idea! Done!

I'll let you know how things turn out when it arrives.

The photo below shows the existing ground glass on my Walker and the two clips that will hold the new lens in place.
