All those extra surfaces to collect dust and the occasional print that shows Newton's rings (despite the glass manufacturer's insistence that this is "anti-Newton's ring glass") leave me doing my utmost to avoid complicating matters even more by using glass for 35mm printing!

Hey Steve
I made some test with the different lenses and couldn't tell anything different with my enlarger. I have been playing with the glass carriers and I did find that without glass my edges were fuzzy from the center sharp with out glass. This was wide open on the lens though. I am going to stay with the glass for the time being. I did see some dust spots but that is normal for my setup anyway. I haven't come across the rings yet but will deal with that when and if it happens.

Thanks for your info.

Richard
