I wanted to see if anyone had any suggestions for ND gradients (soft edge) in 4" x 5.65" size. I have found great glass filters, but wanted to consider optical resin if they are available. Any suggestions?
i would stay away from resins in that size if you at all can.. unless you cant afford glass. Resins can scratch pretty easy and i swear to god attract dust somehow.
I would love to purchase glass, but they can be fairly pricey. Typically, I just rent what I need. I have used 4x4 optical resins in the past, but haven't tried them in Panavision size.
As for your comment, "and i swear to god attract dust somehow"...
Your right, the surface charge of a dielectric like polycarbonate can take nearly forever to normalize, so yeah they really can attract dust. I haven't had any scratching problems with the Lee's that I have used, but I am aware of their nature and have been very carefull.
