Methodology

I've taken that data and re-coded it to be numeric-based, and put it all in a database, to make cross-comparisons simpler.

For Gary's distortion assessment, I broke it into two bits: distortion type, and distortion severity, using the following numeric codes. So if his test said "slight barrel," it got a score of "1" and a type of "barrel." If his test merely noted the distortion type, such as "pincushion," it got a score of "2" (exists).

For a few of his tests, he said, "very slight" distortion. In that case, rather than insert another integer into the scheme, I listed the distortion type with a value of zero. If distortion was mentioned as "none," I have NULL for the distortion type and a value of zero. If distortion was not mentioned, it got NULL in the database, and shows without any value in the tests table.

For Gary's contrast assessment, I assigned a numeric code based on descriptive words Gary used. If he used other words, I guessed: I took "contrasty" to mean "high contrast," for example. If no contrast rating was noted, I entered NULL in the database. In a few tests, Gary had separate contrast ratings for centre and corner — I simply used the centre rating.

For anything that Gary used an alphabetic code for, I substituted the following numeric codes. This includes centre and corner contrast and vignetting. In some cases, Gary used the average of more than one lens copy, and had ratings like "B/B+" — in such cases, I simply used the first rating, or "B" in this example case.

Controversial Choices

  • I include a "Rating," which is simply the average of all the non-empty (NULL) individual scores for a particular lens test. This has a strong bias against distortion, which is not reported on a per-f-stop basis, so it is weighted about 1:5-7 against the per-aperture measurements. Because empty (NULL) entries are not counted in the average, a few tests that lacked entries for the smallest apertures could be biased upward, since the smallest apertures are generally worse than other apertures. Gary warns about the validity of making any cross-comparisons, unless they were what he called "paired" comparisons, but there you go. Your results may vary.
  • Lenses are typically compared by relative apertures, rather than absolute apertures. You don't necessarily want to know how a lens with a maximum aperture of f/5.6 compares at the same absolute aperture as a lens with a maximum aperture of f/2. So I entered test data relative to a lens's maximum opening. That maximum opening is noted in the table, which correlates with the "-0" test result. Note that this may change on zoom lenses tested at various zoom settings.
  • When Gary included only one vignette or contrast rating, I assigned it to only the wide open aperture. The other aperture entries were left blank (NULL), and were not counted in the total score. Since both vignetting and contrast are strongly affected by aperture, it didn't seem right to assign a single observation with the entire aperture range, nor to assume that subsequent entries would be "A" or any other particular grade. This results in a bias against vignette or contrast as the case may be, similar to the bias against distortion mentioned above. The exception is when Gary says something like, "contrasty at all apertures," which I duly entered for all apertures.
  • Lenses with a maximum aperture that does not fall on the conventional "square root of two" scheme were entered as Gary did, with the maximum aperture as "-0" and the next "click stop" aperture as "-1," even though it was always more than one f-stop difference. (I did not note any lens that had, for example, a test at "3.5" followed by one for "4" — they always jumped to "5.6.")
  • I did a bit of creative re-organizing with some of the less-structured data, calling information that potentially impacted the test, such as camera, support system, etc., as "test conditions" and calling everything else "notes."
  • In most cases, anything Gary had in his "Notes" section that had to do with contrast, I changed to a numeric code, and did not duplicate that information in the "notes" field.
