but with my brand new Reducer 0.8x field flattener. even the edges aren't very good looking. not to mention the far corners
Tried increasing spacing by 0.5mm and it got WAY worse.
So it looks like my T2 ring is too thick.
How do I get a slimmer T2 M48 ring so I can adjust the spacing closer for my canon SL1/100D
Do slimmer T2 rings exist? Or do I have to send it to a shop to have them slim it down with a lathe. or custom built one from scratch?
Edit: I think I found one but adjusting the spacing with it will be very tricky. its ultra precise https://davidastro.com/ts-optics-ultras ... -m48x0-75/
Would this work for me?
