AW: Kontrast-AF der G1 – die Zukunft des Autofokus?
...So ist es, die gleiche Technik die wir seit Jahren schon kennen....
Viel scheinst Du über die Technik die Du schon "seit Jahren kennst" aber nicht zu wissen, wenn das die Zusammenfassung ist:
...Aber es kann ja sein das Panasonic das ganze etwas verfeinert hat. Dazu kommt grössere Sensor der bei der Kontrast AF die Messungen macht (ob das Vorteile bringt ???). Und das die AF Berechnung der Prozessor übernimmt kommen bei der G1 gleich zwei Stück zum Einsatz. Wie es bei wenig Licht aussehen wird werden wir noch sehen....

"Sounds like Panasonic are being conservative in their AF timing estimates.
As Richard and Simon said in the preview, we were hugely impressed with the AF speed of the prototype G1 (remember we actually had one in the office for about a week to do the preview). It is *much* faster at focusing than any CDAF system we've used before, and easily a match for any entry-level DSLR. Now admittedly we did only have the standard zoom and not the telezoom, but as we could only test it in the office, we were by definition using it in pretty low light levels, and it had no problem at all.
Panasonic have clearly thrown their considerable R&D resources (not to mention existing expertise in high-end video and display technologies) at solving the problems everyone expected to see in the 'EVIL' concept, and the result is an astonishingly cohesive implementation, particularly for a first generation product. Quite simply it leaves all SLR LV systems trailing, be they from Sony, Canon, Nikon, Pentax or Olympus."

"No, but it certainly seems at least as fast as any entry-level DSLR (including the Alpha 350), and then it has a shorter shutter delay as there's no mirror to flip, which also makes it quieter.
However the G1 can also match all of the strengths of sensor-based LV DSLRs, including true 100% frame coverage (including in the EVF), the greater accuracy and positional flexibility of CDAF, proper depth of field preview, and extremely accurate magnified manual focus. Add in the fact that it can freely track a subject across the frame in the way no SLR can match, and you might begin to understand why we're excited.
The G1 is also smaller than any DSLR, but with an EVF as large as the viewfinder on most FF DSLRs, and has a superbly sorted control layout plus that excellent fully-articulated LCD. So unlike the A350, it doesn't compromise other aspects of its operation in the name of LV functionality; and unlike the 450D, LV continues to work on moving subjects.
Now all we're hoping is that Panasonic can deliver the goods on their new-generation 4/3 sensor; if they do, the G1 may make all of the DSLR manufacturers really quite worried."
