Actually they did it they sent some lenses for reviews and to some photographers like kenspo. Kenspo showed a few pictures, ephotozine reviewed it and noted for example that the AF was hit and miss.
"
Focus accuracy with phase detection could be a little hit and miss, so care may need to be taken, especially when shooting erratic, moving and difficult subjects. The minimum focus distance of 1.2metres is fairly typical for a lens of this type."
While their review of the 150-450 was flawless.
Ironically, Pentax then decided to not release the lens and instead fix it. I don't think that ephotozine could have find that focussing issue if they where just based on specs sheets or didn't got a sample in hands. I don't think neither they have been paid by Pentax to say that.
We can criticize ephotozine but overall the review they did on the different lenses I own tend to match reality.
