Lens "porn" with the Df: The 105 mm Nikkors. Part 1

The choice of 105 mm focal length set Nikon apart from other systems in the older days where offerings typically were either 85 mm or 135 mm. The intermediate 105 mm class  aims to cover a lot of ground and really can be considered being a general-purpose lens. The better then that the various 105 Nikkors belong to the some of best lenses ever made by the Mothership.

The 105 mm Nikkor range comprises fast (f/1.8, f/2), medium fast (f/2.5, f/2.8 ), and slow (f/4, f/4.5) lenses. I'll walk through them in turn. Here are the extremes in terms of external appearance: the fast and fat 105/1.8 and the skinny 105/4 Nikkor-T. Both are manual lenses and the tiny f/4 has a preset aperture ring. The 105/4 T quickly disappeared from the product list while the f/1.8 persisted longer, but then reborne as the specialised AF-D 105 mm f/2 DC.



Both of them have CPU for improved handling and metering. The little 'T' has a "G" CPU whilst the f/1.8 being an ordinary AIS design employs an ordinary "P" chip. The f1.8 has the wobbly slide-out hood Nikon designers were fond of in the late '80s and takes 62 mm filters, whilst the 'T' uses equally tiny 34.5 mm filters and have a cute little snap-on hood to match.

Today's shooting occurred at taxing winter temperatures, around -13 C with strong wind. Quite unpleasant but still better than the grey pea-soup thick fog that had engulfed us here for over one month. A dusting of fresh snow and a few hours worth of a pale winter sun made the views more than enjoyable than the ambient temperature would indicate.
 
I used the Df the entire day with gloved hands and had no problems in operating the camera. Battery held out as well.

I'll post some more  images later. For now, just snap of an industrial facade enveloped  in that very soft, almost warm blue Nordic light occurring right after sunset. In the deep winter this light lasts for a short time, perhaps 20 minutes, while later in spring the period extends to hours and in summer lasts almost through the entire night, if you are south of the Polar Circle (otherwise there is the Midnight Sun).

This capture shows the extremely delicate light gradients the Df can capture, with a great dynamic range. I used 105 mm f/1.8 Nikkor AIS for this picture.

The "sunstar" in that image is stunning!   :o  I am getting a 105mm as soon as funds are available and am torn between the 1.8 and 2.5.  Would you provide some input?  I understand the 2.5 is more highly regarded and the 52mm filter size sure is convenient, but I would also like the option to use it for shows where I typically am at f/2 just to get iso 8-10,000 so f/2.5 worries me.  How do they compare at equivalent aperatures, and does the 2.5 produce sunstars as stunning as the 1.8?  Thanks in advance!

The picture was captured at f/11, thus many lenses would make a similar starburst provided strong point light sources are present.

From f/5.6 onwards, there isn't much practical difference between the 105 mm f/1.8 and f/2.5.  Obviously, at wider apertures than f/2.5 the faster lens "wins" :D

I use tripods so not too concerned about high ISO. In fact, this shot was with the Df set to ISO 200.

IIRC, the f2.5 (except for the earliest version) has seven aperture baldes and f1.8, nine, so the f1.8 offers more streaks to the sunstar...

A valid point in favour of the faster f/1.8 model - at least for starbursts ....

However, the influence of the increased number of aperture blades on bokeh is less obvious.

Definitely a plus for the 1.8.  I'm mostly impressed by how sharp and contained the rays are with the 1.8, my 50mm 1.2 makes 18 points as well, but some of the rays don't stay as focused as your 105mm 1.8 produces.

The 105 mm f/1.8, while not as ubiquitous as the slower f/2.5, is quite easy to get on the second-hand marked. However, it tends to be priced rather expensive, sometimes even going for more than the AFD 105 mm f/2 DC Nikkor.

Aside from the very first version with nine rounded aperture blades, the bokeh pattern when stopped down by 1-2 stops looks the smoothest on Nikkor P C or Ai versions of 105/2.5.  The aperture blades of Ais makes a gear-like or harsh septagon.

Akira: the very reason I favour my early AI 105/2.5.

I like the same versions, too.  Plus the focus throw is longer on these lenses, which makes noticeable difference when focusing on live view or on mirrorless cameras.

I think when I have the funds, I will get a copy of either and do some extensive testing to see how they compare myself.  Thanks for the insights, I will make sure to get the earlier versions that both of you prefer.

Good luck.  Any multi-coated versions, either with the rubberized or metal focusing rings are essentially the same as the versions we like.  Just avoid the Ais version.

While revisiting this page, I recognized the place where you shot this picture (second post). I remember an IR shot with a yellow chair, right?

That is correct. This is a place I drive by many times a year.
