Playlist with videos of DA* lenses hunting

asdf · 03-12-2009, 07:54 AM

One of the forum members complained about 55's AF speed. So I collected several videos of different youtubers letting their DA* lenses hunt. However, it's definitely not the best test of AF speed and it's not even the best comparison of lenses hunting, because each one may be on a different body and/or a body with batteries with different charges. 16-50 seems fastest, 50-135 seems slowest, while 300 isn't on the list yet.

Nevertheless, enjoy videos of pretty lenses:

Interesting - but I isn't there a difference in kind between lock-to-lock focus travel speed and getting the lens and AF system to actually lock onto a specific object?

That would be my guess, as well. There are other videos on youtube with people focusing on objects near and far, which seems like a better test. However, I couldn't find videos of that sort involving DA* lenses.

EDIT: Here's a couple (I haven't made any of these):
