That's true William. I just don't know where else (photodo) to look, in order to compare - let's say a fast AF 80-200mm from Pentax, Sigma,Tamron and Tokina - the four typical choises for a Pentaxist like me. I guess the MTF tests are limited to being 2-dimentional (flat target). In real life a sfere arround the canera in focus distance is perhaps more useful as a "taget".
Pentax ought to make third party (only high quality F2.8 or better) lenses for Canon, Nikon, Sigma, Minolta and PENTAX, naturally. This way they might sell a whole lot more glass and get the cost down, due to higher sale numbers. This could perhaps be an optional survival strategy. A part of the profit should go to delveloping better bodies, featuring: 1. Larger Buffer (5 shots are not enough) - 30 seconds to empty is not fast enough. 2. Faster AF, better AF in low light 3. Fill flash options (adjustable output with camera in TTL mode) 5. Image Stabilizor 6. I liked Power Zoom 7. HSM/USM 11. Accommodating Non-A lenses (what the H... is wrong with an aperture ring - most camera lenses on Earth have one).

Photodo was pretty much discredited regarding testing Pentax lenses several years ago when they started giving low scores to lenses known to be best in class performers. William Robb
