I understand Bryan, no problem with me, I just found it curious as to why the AI Servo performance wasn't as good as those from the 20D/30D/400D/450D before, when it uses the same AF module. Also, I noticed this in your review:


And while it should not be news-worthy, the Canon EOS Rebel T1i / 500D's sensor arrived clean out of the box and has not needed a cleaning to date. I will note that this is not the latest Fluorine-coated system.

It seems to contradict what the Canon USA press release linked at the bottom of the 500D review said:


EOS Integrated Cleaning System

With the introduction of the EOS Rebel T1i camera, the entire Canon EOS system is now equipped with the highly acclaimed EOS Integrated Cleaning System. The Self-Cleaning Sensor Unit for the Canon EOS Rebel T1i has been upgraded with a fluorine coating on the low-pass filter for better dust resistance.

Lastly, this one, an issue which continues to confuse me since I keep reading contradictory info on other sites discussing the 500D specs:


One of the significant upgrades in the T1i over its predecessor, the Canon EOS Digital Rebel XSi / 450D, is the new, up from 12.2 MP and Canon EOS 50D-matching, 15.1 megapixel sensor (though the microlenses are not gap-less like in the 50D).

The DPR & RG sites still state thatthe 500Dalso has 100%-coverage, gap-less microlenses like the 50D sensor, while still other sites say the opposite. Can you tell us if the info you got was directly from Canon? Thanks again, since it doesn't make economic sense to me for Canon to build yet another 15MP APS-C sensor just for the 500D when they already have one for the 50D. If it's indeed true thatthe sensor does not have gapless microlenses unlike the 50D, how then can we explain the apparently better high ISO performance of the 500D compared to the 50D? Is it all due just totweaked onboard image processing, or lower read noise from having just 2 readout channels & a lower FPS needinglower-clocked signalling? [^o)]
