Exactly! For example, when shooting test shots for the EF-M 18-150mm review on TDP, I found that my lens delivered results similar to the EF-M 55-200mm, but on TDP's test charts the M18-150 looked much worse. I shared comparison images with Bryan, he got another M18-150 and re-tested it, with much better performance. The issue is not really with TDP, but with the copy variation inherent in lenses. That means relying on any one test site is not a good idea, the exception being LensRentals when they do optical bench testing of several copies of a given lens.I also usually rely on TDP when selecting lenses.
Yet, his "image quality results" can be misleading. If you look at those for the EF 180 macro, without checking other sources, you won't ever buy it. Looks optically mediocre, despite being one of the sharpest Canon EF lenses.
And he is sometimes just too polite, if you know what I mean...
I don't mind it at all, but I agree with the 'too polite' characterization. He pretty much always finds ways to praise lenses, compared for example to Klaus at Optical Limits who doesn't pull punches. I do stand by what I said about motivation, anyone who reviews gear and earns income from affiliate links is likely to be biased in favor of recommending the gear they're reviewing. TDP was only Canon for many years, but then expanded to include Sony and Nikon camera and lens reviews, even though AFAIK Bryan still primarily shoots Canon. Why? Revenue, of course. Bryan is like any writer or journalist with a 'style', and if you know that style and factor it into your evaluation of their viewpoint, it's not an issue.
