I used my infrared camera for the first time yesterday.
This is a Nikon D3400 with the internal IR blocking filter removed.
I used a Cokin 007 Infrared filter in front of the lens to block most
of the visible light.

Have you tried it on heat sources?

Very nice! I have a question, as you mentioned your converted D3400, it was converted to 'so called 'Full Spectrum' conversion. It gives the camera more option to use different filter with different wave form of the IR. I just want to know, were you using the Live-View or view finder for focusing? Did you have any difficulty to see when focusing with viewfinder? I converted one of my old P&S, the Panasonic TC3 to full spectrum and using a Hoya R72 filter in-front of the lens, it works great. I am planning to do the same conversion on my old D200, but I wonder if I will have problem on focusing with the D200, because it doesn't have Live-View. I can only use it's view finder, that will give me trouble when focusing.

wingclui44-
I was using "Live View" to focus.
I had read that it was more accurate to focus using this method than using the view-finder.
The problem was that TWO camera batteries were DEAD within two hours!
(I'm travelling and I left a third battery at home, not realizing I would need it!)
As far as focusing using the view-finder, older manual focus lenses used to have a mark
to indicate how much to adjust the focus for infrared. Most modern lenses do NOT
have this mark! (It is closer than the focus point for visible light.)
Do you happen to have such a lens to use with your D200 camera?

Oh yes, I have several pre AI; AI AIs lenses from the past, I am using them all on my Df too. Besides that, all my other AF lenses are D type or just AF, not G type, it mans lenses without focus motor built in, except the Nikon 300mm f4 AFs-D ED IF prime I have, all have aperture ring.
I still can't make up my mine yet to convert the D200, and the price is expensive, My Panasonic converted P&S serves me good that I converted it myself at home!

Thank you!
I love taking things apart to increase my knowledge, I am skillful on tools, thanks for the other member of the UHH, who encouraged and showed me how to do it and I did it!

I have already discovered two problems with an infrared camera:
1. It is more prone to lens flare.
2. With the conversion of my camera I was told that the built-in image sensor cleaning
mechanism would no longer work. After just 2 days of use I had to manually clean it today.

I don't know the reason of lens flare happening particularly on IR, it does happen to any camera depends on the lens quality and design, but the second part is true, because using live-view tends to attract more dust on the sensor over time!
