Some of the hidden virtues of the old Nikkors are their often surprisingly good performance for infrared (IR) photography. Most of my IR work thus is conducted with various venerable manual-focus Nikkors. Even the "dog" Nikkor, the 43-86 mm f/3.5 Zoom-Nikkor, turns in a healthy result with IR.
For true IR photography, a camera suitable for IR must of course be employed. Fortunately, many of the older or newer Nikons can do well once they have been modified for this purpose. It is a great way to "recirculate" old cameras no longer deemed useful for mainstream photography. Most of my IR cameras have had the internal filter pack (ICF) replaced by an IR long-pass filter, such as the popular R72-class with 50% transmittance at 720 nm, thus into the near IR. I have a suspicion that the CCD-typ sensor holds a slight upper edge against the current CMOs technology; however, the pixel numbers of the newer CMOS models surpass those of the CCD generation. So if sheer resolution potential is desirable, modifying a newer camera might be the preferred option in the end.
I used earlier Nikon D200 and d40X for Ir and still keep these cameras as a backup for my current IR main camera, which is a D5300. I landed on the D5300 as the first choice because it had good resolution (24 MPix), built-in GPS (very important to me), and fast-working LiveView. As virtually all of my manual-focus lenses are CPU-modified, lens compatibility was not an issue as far as camera selection was concerned.
I plan on showing results obtained in IR with old Nikkors in this thread. Contributions from other members are most welcome, but keep in mind the topic is the use of Nikkors, preferably the older ones.
Below is my current main IR camera, the D5300, with a true oldie attached to it. The lens is the Nikkor-T 105 mm f/4, a lens briefly produced in the late '60s as a spin-off from a similar design for the Nikon S rangefinders. In fact, the rangefinder 105T is identical except for the flared rear mounting part which obviously contained an S mount instead of the F mount shown here.
