Tested on film only.
Another very compact design, that performs marvellous.
It produces biting sharp pics, with a tendential high contrast and saturation.
It will fit into a pocket, and it is even cheap!

Review: Nikon 18mm f/3,5 Ai
Picture from Nikon.com
Tested on film only.
A very compact design, that performs in a charming way.
My sample, at least, had a very particular way of rendering the highlights, whit a smooth pleasing graduation of luminance values.
It is quite sharp, too. Even the borders, but well stopped down, to f/5,6 or f/8, are quite sharp.
In short, a nice little ultra-wide, that will fit into your pocket.

Review: Nikon 35mm f/1,4 N Non-Ai
No doubt one of the sharpest lenses I ever owned. Period.
Just a trace of softness / veiling haze at full aperture, than from f/2 to f/11 it really shines. From f/11 the diffraction start to wreck his performance.
On infrared the only problem is to achieve correct focus at wide apertures, but if you use Live View or guess or stop down a bit you will regarded with a perfect rendition.

In short a real Nikon legend. And did I mention that is 5 times cheaper than the Canon equivalent? (but keep in mind: the Canon is AF, and sharper at full aperture)

Review: Nikon 28mm f/3,5 Ai
Marvellous and dirty, dirty cheap (obviously used).
In visible light is an excellent performer, but it shines in infrared.
The images taken in IR with this lens are just superb, and literally “pops out” from the display.
In a single sentence: get it! (especially if you shot a lot in IR)

Review: Sigma 10-20mm f/4-5,6 DC HSM AF
(Will not work on full frame, on DX equivalent to a 15-30mm)
A very good performer indeed, if you don’t care about it’s border sharpness (only so-so).
If you need it as a reportage lens buy it and you will not regret your money; if you want it to use as a landscape lens try to test it before you buy to see if it met your expectations.

For infrared use it is a “mixed bag” lens: really really sharp in the middle of the frame, but often with the borders not up to my standards and, only sometimes not everytime, a big hotspot in the middle.
Again: if you can try it before you buy it.
