About 40 minutes in we experience some audio issues and the quality degrades and suddenly Graham is replaced with Wallace Shawn (thanks, Ethan). Sorry about that. 

There are quite a few swears in this episode. 

We welcome Erik Mathy (IG: erikhmathy) to talk about homemade lenses, how he got from the Land of Cheese to the Land of Fog, why you should match your lens to the subject you shoot, and many other things.

Simon Forster of the LFPP (https://largeformatphotographypodcast.podbean.com/) and The Classic Lenses Podcast (https://www.classiclensespodcast.com/) wrote this in the YouTube chat during the show: Suggestion for the title of this week's show; Graham's Felt-Lined Shaft. That's all on you, Simon.
