Thom implies Canon's quality control better than Nikon’s

Interesting read

4. Lenses and cameras aren’t consistent.

I saw as many samples that were +20 as 0 as -20 as any number in between. Random. As I noted, the 16-35mm, 24-120mm, and 70-200mm f/4 all fell into a decent bell curve centered on 0. As did every Canon camera/lens data set I’ve seen. So it can be done. Just that Nikon didn’t do it with every lens.

5. Repeatability.

The DSLR focus systems have a “tolerance” to focus. They’ll report “focus achieved” for a small range of distances. That’s been true since the early days of film SLRs with autofocus, as was documented by the late Herbert Keppler in Popular Photography decades ago. My sense is that Canon has achieved better repeatability than Nikon in recent years. My suspicion is that Canon’s manufacturing tolerances are tighter.
