Originally posted by Class A I concede that I do not know how slow that Tamron lens is and that an adapter scenario is not ideal. The drastic failure is definitely just anecdotal but nevertheless perhaps one piece of evidence for the notion that DPReview's findings are not entirely reliable.
Therein is an issue.. Rishi claimed a forum member's own AF test proved his own review findings. However, the member AF test used a variety of older lenses for the K-1 and the baseline (a Canon 5d) used a high value single point. That is fine if you simply wanted to compare camera A with a variety of old lenses to camera B with a single lens. But that doesn't detail the story. Plus, that single point of data was rather high (using a 70-200 USM F/4) and the K-1's were an average of many points (some much approaching the 5d baseline, others woefully not even near) which make it look rather poor.
For whatever reason there is some kind of chip on their shoulders when anyone mentions the 'P' word. I don't even care if I didn't use Pentax products because their view, while subtle, is still rather clear. Rishi especially.. He argues his claim and shoves it down peoples throats in the Pentax section of their forums. Then, when several others came in to diffuse the situation, he still doesn't back down -- literally claiming everyone else is wrong and he is right.
No agreeing to disagree, no just walking away. So it is rather political over there with the DPR staff. And it does seem like a political campaign looking to make mountains out of molehills on any sort of flaws in those they don't want to see succeed, while dismissing any flaws in their own 'candidates.'
I'm sure they'd say "We test cameras as they are, in order to show what they are" but that is a load of bologna when they weigh AF tracking so highly throughout the conclusions on one review and not another. It might be, comparatively, worse off. But the tests so far don't definitively prove it as they were conducted. They even claim single AF acquisition was hesitant. That is what really got me looking deeper. Because, it wasn't hesitant on my Pentax digital bodies from 6 years ago, I doubt the K-1 is any worse. How could it when the AF module is 4 versions/generations newer?
It is so frustrating reading slanted opinion formed as an objective review, because others will read those opinions thinking they are truth, then we have to deal with people who now believe these heavily slanted opinions. Doubly worse when they're tied in with a major retailer (Amazon).
The hilarity of that, though, is the 'Top customer review' of the K-1 on amazon is a 'converted Canon 5d user'. Who makes no mention of hesitant or inferior AF. As a matter of fact, they appear to be ecstatic about the new Pentax body.
But the more I see DPR respond, the more I get a feel for their true colors. Of course there is some fanboyism in the Pentax section of the forums, but that isn't the issue here. Take DPR with a grain of salt.. treat them as a single data point..
It almost reminds me of a movie critic.. hates/dismisses a movie (perhaps because they don't understand it; trying to make it something ti isn't designed to be), yet it still gets really high marks with the actual audience (who do understand it and appreciate it for what it is).
