These were shot at Butterfly World near Fort Lauderdale, Florida.
They don't allow tripods or monopods so it is tricky to get them in proper focus
shooting hand-held.

I've used my converted D3400 for just two days so far.
Since there is no permanent IR filter installed over the image sensor
I can use various filters on the front of the lens.
In the case of these two photos I'm using a Cokin 007 Infrared filter.

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.

Just natural light- softened slightly by a roof screen they have to keep the butterflies contained.
The screen also allows the wind to blow through (which was a problem)!
I had brought, and intended to use, an LED ring light / flash,
but after spending a couple of hours in the heat and humidity I was utterly drained
and had to leave before I got to use it.

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?

Two flowers photographed at Butterfly World in Florida
on Monday, March 25, 2019.
They don't allow tripods or monopods, so hand-held it was.
120 mm Pentax macro lens (from 645 medium format system)
used on a Nikon D750.
