IR Mania with old Nikkors

[Bill De Jager]

Here was my lens of choice today, on a Sony A6000 converted to broadband:

S 105 2.5 PC by Bill de Jager, on Flickr

It's the S-mount 10.5cm f/2.5 P.C.  This is a Sonnar lens that was reissued in F mount later, before being superceded by the double Gauss 105mm f/2.5 lens that's more familiar to Nikon users. According to Roland's site, the S-mount version started production in 1953, the F-mount version started in 1959, and the optics changed in 1971.

I used a B + W 093 filter to get a fairly monochrome IR look which I then desaturated.

The second photo is not a negative despite its appearance.  I did darken the sky to black to increase visual contrast.

Nice old-timer IR, Bill. I haven't used the 10.5 cm f/2.5 S for IR yet, only the slightly modified 105/2.5 F "Sonnar" version. However, all of the 105/2.5 versions apparently are performing well in IR.

Examples of 105 mm f/2.5 Nikkor (AI) for IR. The Dutch mills with D5300, the soaring seagull with D200.

Another favourite with IR is the 16/2.8 Fisheye-Nikkor. The f/3.5 version is a tad sharper, but doesn't allow as close focus (Erik modified my 16/2.8 to give extra close near limit).

On the DX cameras, the fisheye geometry becomes less overwhelming as well.

The 16/2.8 Fisheye-Nikkor is also perfect if one wants to shoot flying bananas in IR.

Your IR photos are always huge treat, Bjørn. What nm filter was used in this modified D200?

[Bjørn Rørslett]

720 nm class filters on all of them.

Thanks, Bjørn.  I really enjoyed working with this lens.  One thing to watch out for is that changing the aperture tends to inadvertently change the focus.  Also, the lens is vulnerable to flare; I should have looked for a hood to fit onto the 52mm filter threads.  The biggest problem I ran into is the usual one with using a manual-focus lens handheld on a mirrorless camera - focus peaking only provides approximate focus accuracy. The lens is plenty sharp when it's actually in focus.

Next lens: Nikon PC-Nikkor 35mm f/3.5, old version with chrome knob, on a Metabones Speed Booster Ultra (because I couldn't find my F- to E-mount adapter) and Sony A6000.  The lens was not shifted for any photos.

I also couldn't find my 720nm IR filter, so here are more with the B + W 093:

I took my 28mm 2.8 (min focus 0.3 m) for a spin today with the ir D80.  Metering was a wild guess. Most images are around f/8 and 1/320 s at base iso. Here you have some distant, medium and close range. The images came out full of detail.
