Are you now going to point out the weaknesses in every other camera out there, or is it just Pentax that deserves this treatment? You did bring it up, so you just have thought is was important. Or were you under the impression that we all thought Pentax had the best AF out there?
Originally posted by FantasticMrFox I bought the camera that suits my needs best, and I get along with it splendidly, thank you very much.
But you love to point out other cameras that may have better AF, as if that were somehow relevant? What wid dat?
I'm not going to analyze DPR to find out exactly what I don't like about them, but I find them amateurish.
But if we're talking credentials, I have 50 years experience shooting Pentax, 15 years experience teaching photography, a year of school in photography, at least 10 working pros I've discussed photography with for years, and here's my take on this. I don't get caught up on the little stuff.
IN my sequence above, I used my F-70-210, because it's my fastest focusing lens, and despite what's been posted here, my reference for sharpness is the tennis ball in the dog's mouth and it stayed in focus. Which means the camera was tracking it. And I didn't even get a good focus lock on the first frame. The camera picked it up, which to me seems pretty incredible. But see here's the difference. I know which is my fastest focusing lens. It's either the Tamron 90 macro or the F 70-210.
I don't have to test a pile of lenses to know that, because I use the equipment all the time, and when I want fast focus for medium wildlife I shoot with the F 70-210. Sometimes fast focus trumps resolution. Did DPR shoot with an F 70-210? Then in my experience, they didn't test the AF system, they tested the relatively slower speed of the lenses they used. So technically, they didn't test the AF at all, they tested the speed at which lens could focus.
When a subject is coming straight at you, you are actually testing how fast the AF drive unit moves the lens elements. Not the AF. The problem is, if the company comes out with new lenses that move the elements faster, then the AF on the system will be better. So what exactly did DPR test? We don't know, they don't know.
Their test is completely irrelevant to me. And it's only relevant to anyone who owns both cameras and the lenses used on those cameras and can choose to use one or the other. SO why would DPR put 99% irrelevant data into a product review? Quite simple, they have an agenda. Why would they even mention one other product? That's tacky. If they wanted to mention all the products that have better AF than Pentax, fine but one? Sorry, completely unprofessional.
You might want to take a second to comprehend this.... a test is only good, if it tests what it claims to test. Many times people will devise a test for something that doesn't test what they think it tests, and then proclaim the test from the roof top. But then, back at Ryerson Politech, we spent a lot of time discussing system testing, blowing up the flaws in testing procedures, understanding why when hype made a system sound fantastic, the results rarely met the hype etc. My problem with DPR is they so often don't meet the minimum standards I'm used to, and can't see out of the box they think in.
I see way to many flaws of logic in their text, commentary and conclusions, it's painful to read them. Maybe the less educated will be hoodwinked. They do provide good descriptions of the cameras they review, just don't get caught up in their technical analysis. There, they are amateurs.
Results for these types of tests, are relevant only to the lens and camera tested. Generalizations based on that aren't worth publishing.
