    Re: Digital IR

    Just got back from our trip. It was a lot of fun! Lot's of great stuff to see. I did find out that my Nikkor AF50 f/1.8D has a hot spot in IR the shape of the aperture. It's not large, and it...

    Re: Digital IR

    JG, it is a very good suggestion to check for focus shift. Most of my lenses have an IR mark, and a test wouldn't be hard to do, but it'll have to wait a week or so, as tomorrow I'm going on my...

    Re: Digital IR

    Andrew, I'll be very curious to find out how the 680nm filter works out. I expect it's give a good IR effect while being significantly faster than the R72.

    The best way to figure this out is to do your own tests. If you don't know what your particular exposure/development system will lead to, then you're just rolling dice. If the roll has important...

    Re: Digital IR

    Andrew, that's good news. It's my understanding is that most digital cameras have an IR blocking filter. So my results are more like using an extended red film, such as Ilford's SFX 200 film.

    Search for camera light baffle, camera light seal.....they bring up quite a few hits.

    I have an extended silicone cup viewfinder hood. A rear Nikkor lens cap fits over it perfectly.

    I hope it works out for you!

    Give it a try. I've only used primes. Make sure to cover the viewfinder. According to Lifepixel, some lenses are known to cause hot spots.

    Thanks, Andrew. Yep, I'm just using an R72 filter on a regular D600. By any chance, were you using a zoom lens? Did you cover the viewfinder during exposure?

    The big difference is the converted cameras are faster, and you can see through the viewfinder. When I put the R72 filter on, I can't see anything. So that use is strictly tripod-only. The color...

    Sorry to hear about this. This is my favorite lens for my GX680 system, and something is obviously wrong with how the lens is mounted. I would not describe the OEM lens as "dreamy and ethereal".
