Subject: Filters For The TL-120
Date: 2011-01-15 18:38:20
From: Steven Lederman
There's a chance I may be able to get my hands on some expired Konica Infrared film, and I think it would be great to shoot some stereos with it.  I understand that a good filter to use when shooting infrared is the Kodak 25.  Are Kodak 25 filters made in 80mm that would fit the TL-120, or do I need to buy the filter in a different size and use an adapter ring?  I guess I'll need three of them - where's the best place to purchase Kodak 25s?
Anyone here shoot medium format infrared?  Any tips are welcome.

80mm? The TL120 has 46mm filter rings.
Are you going to try to span both of your taking lenses with
one filter?

Any 25 red filter should work fine with Konica IR. The filter size is 46mm. You only need 2 of them. It won't do any good to see the image through the filter. You can use 46mm or something larger with an adapter ring. I use 49mm. I have shot hundreds of rolls of medium format IR (mostly Konica). Feel free to email questions to me.
