Your experience is a valuable one Jim, however other users also with similar experience using the original focusing screens and the Maxwell screens have a different opinion, this is Daniel Ridings opinion taken from a public discussion on the topic and you can find similar opiniions in the web: " I just want to confirm Carlos statement that some find it more difficult to focus with the brighter, after-market, screens on older Rolleiflexes and Rolleicords. For Rolleiflexes with a 2.8 viewing/focusing lens, I've gone back to just the original stuff. For Rolleicords (the older ones, V and before) that have 3.5 viewing lenses, I've tried both. I have a Maxwell screen in my Rolleicord V, but I opted out of installing one in my Rolleicord IV or the Rolleiflex I got from Phil. I could have had it installed in the Rolleiflex, but in my experience, the brighter screens just do not "snap" into focus. The whole screen looks good, so it is difficult to find the point that is in focus. I came across a Rolleigrid on eBay a while back. I just pop it in the Rolleicord, but when it comes to the Rolleiflexes, I have just never needed one. I had a brighter screen in my Rolleiflex E, but I ended up putting the original back. As they say ... your mileage may vary. It's a personal thing.
