NIKKOR IX APS-C Lenses
Before the APS-C DSLR came the APS film SLR, and with it a series of 1.5x crop factor lenses known as the IX series. Even though they have angles of view and coverage circles comparable with APS-C DSLRs You cannot use them. Why? because they reach further into the lens mount, interfering with the mirror. It would be possible to use them with full-time mirror lock-up, but then you wouldn’t be able to focus, or , on all but professional cameras, set the aperture. But, just for fun, here’s a rundown of what was available between 1996 and 2000.

Reciprocity Failure
Beyond a certain length of exposure, film no longer absorts light in a linear fashion, requiring longer and longer times to achieve the equivalent exposure. This is known as reciprocity failure, and is important when working with long exposures, such as with pinhole cameras. Here’s a brief guide to some popular films and their reciprocity characteristics.

Flange Focal Distances
The distance between the outermost surface of the lens mount and the film/sensor plane is known as the flange focal distance. SLRs typically have longer distances to acommodate the mirror, which results in larger lenses. Rangefinders and mirrorless cameras which do not require a mirror box tend to have smaller lenses and more compact dimensions.

Sensor Size Comparison
Confused by how sensor sizes are designated? You’re not alone.
Sensor sizes smaller than small format are expressed in a ratio that describes the diagonal measurement of the frame. For example, a 1/1.7" sensor is 1 ÷ 1.7 = .588", and a 2/3" sensor is 2 ÷ 3 = .666". This gives a rough means of comparison, but doesn’t take into consideration the aspect ratio.
It also doesn’t take into consideration pixel density (the amount of photosites per square millimeter). One sensor of a given size may have a higher pixel density than another of the same size, but that doesn’t necessarily mean that it has a higher resolution. This is because the photosites in a more densely packed sensor are smaller, and have less light gathering ability. This can lead to increased noise, which ultimately degrades resolution.
Here’s a comparison of some of the many different sensor sizes used in digital cameras of all types, along with their physical dimensions, crop factors, aspect ratios, area and some of the cameras they’re used in. Each image is created actual size, although they may appear differently depending on the screen dimensions and resolution of you computer’s display.

Aperture Guide
A quick guide to apertures available on the Nikon D90, in 1/3 stop and 1/2 stop increments:
f/1.0
| These values, for the most part, have been taken directly from the camera. Some of the 1/2 stop values, when rounded by the camera, are the same as the 1/3 stop values. Using this chart, we can see for example, that an f/1.2 lens is a full stop faster than an f/1.8 lens, but an f/1.8 lens is only 1/3 stop faster than f/2.0. However an f/1.8 lens is a significant 1-1/3 stops faster than an f/2.8 lens, a common aperture value. The holy grail of speed, the f/0.95 lens, is just slightly over a full stop faster than an f/1.4. Using Nikon’s claim of a 4-stop advantage using VR, the 16-85mm f/3.5-5.6 would behave similarly to an f/0.95-2.0 lens in cases where it was not used to stop action. In reality however, it would be closer to f/1.2, a three-stop advantage. Not too shabby. On the other hand, the 70-300mm f/4.5-5.6 would be the equivalent of f/1.6-2.0. Still not shabby. So, unless you are shooting sports or other action, purchasing a fast f/2.8 telephoto may not be entirely necessary. It will however cut down significantly on flash recycle times, which may be a consideration. |

Nikkor 16-85mm f/3.5-4.5G: Six Primes in One
The AF-S DX Nikkor 16-85mm f/3.5-4.5G ED VR has six ideal focal length designations on the barrel, which are my go-to numbers. Although DSLR zoom lenses are continuously variable, I find myself going straight to these numbers first, depending on the subject matter. Generally, I set the lens to 24mm, which gets me closest to the classic 35mm focal length. For portraits, I tend to work around 50mm. Starting from the short end:
Like the Canon SD780 IS and Nikon P5100, the maximum and minimum apertures are variable depending on the focal length of the lens. At 85mm, it goes all the way up to f/36! This is not as great an advantage as it seems though, since diffraction begins to soften images above f/11. To get the best combination of depth of field vs. sharpness, work between f/8 and f/11.
Remember the old photojournalists’ saying, “f/8 and don’t be late”.
On the other hand, f/5.6 is a memorable number, as it’s available across the board, and gives good all-around results regardless of which focal length you use. Happily, as long as you don’t manually change the aperture, the D90 returns to the maximum aperture for any given focal length automatically as you zoom back out. But if you change it, it sticks, which is one reason I like to work with a single focal length whenever I can.
Prime lenses such as the Nikkor 20mm f/2.8D, 35mm f/1.8G, 50mm f/1.4G, and 85mm f/1.4G all have distinct advantages in both size and speed over the Nikkor 16-85mm, but VR narrows that gap somewhat. In theory, at 35mm, VR makes the 16-85mm behave similar to f/1.8, (except for the ability to freeze action), but it can't compete with the compactness of the 35mm f/1.8.
| Nikkor 16-85mm f/3.5-5.6 | 35mm equivalent | f-stop range |
|---|---|---|
| 16mm | 24mm | f3.5-f22 |
| 24mm | 36mm | f/4.0-f/25 |
| 35mm | 52.5mm | f/4.5-f/29 |
| 50mm | 75mm | f/5.0-f/32 |
| 70mm | 105mm | f/5.6-f/36 |
| 85mm | 127mm | f5.6-f/36 |

Canon Powershot SD780 IS: Seven Primes in One
The Canon has seven steps as opposed to the Nikon P5100’s nine, and they’re pretty similar. Starting from the short end:
Unlike the Nikon, The Canon doesn’t report the 35mm equivalent focal length in the EXIF data, so I had to calculate it. Camera manufacturers have always varied features between brands, but with digital you can expect even more differences. There are no standards other than industrial design common sense, and camera companies have egos just like any other. Happily, the multi-selector on the Canon controls the exposure compensation, flash mode, self-timer and AF focus range just as it does on the Nikon except that it’s rotated 90° counter-clockwise. I’m actually surprised the icons have been as consistent as they have.
The Menu button on the Canon behaves like the Setup mode on the Nikon, and the Func. Set button on the Canon like the Menu button on the Nikon. It works out OK, because you can get to both quickly with just your thumb. The Nikon requires your left hand and a trip to the Mode Dial on top of the camera. It’s a very different kind of camera, just as a rangefinder is from an SLR. There’s no one perfect camera and I like working with the different designs.
Thank goodness these functions are not touch-screen controlled. If they were, I wouldn’t have bought this camera. If I want touch control, I’ll use my iPhone, thank you very much.
Here are some test shots:
I’m fairly happy with existing light results. Even at low ISO the images are somewhat grainy, so the results at ISO 1600 don’t seem as bad. They’re still much sharper than they would ever be with the closest sized film camera, which would probably use 110 film.
