AF strong backlit subject: will the 1s be better than the x0Ds?

[felix_ing]

Hi,

 

Quick question, will the 1 series AF better in case of a backlit subject (low

contrast, will better glass help?)? If it indeed does, is that because of the

increased number of AF sensors or is that because of an increase of the AF

points' sensitivity?

 

Please advise.

 

Thanks.

<p>It might help, and if it does, it would be due to an increase in the sensitivity of the AF points. Better glass might also help; if you're getting veiling glare, then any AF system will have a hard time working. But no matter what glass and what body you're using, the subject must have some sort of feature which the AF system can lock onto, and there must be enough illumination on that feature for the AF system to see it.</p>
