Originally posted by Alizarine If we're going to compare AF speeds of Pentax screw-drive vs. even the lowest in-lens-motor lenses of Canikon, I think the latter will almost always be faster, same as how the DA18-135 is faster than a whole lot of screw-drive lenses. the camera's "decisiveness" on the AF is what matters to me.
my K-x just feels like it's a girl shopping for new shoes in a lot of situations especially low-light.
it's amazing to what level this bad reputation has grown. sometimes even i find myself believing this stuff at times.
a few years ago, i got to play with my friends entry level nikon (d40) and compare it with my humble k20d (remember, the worse sensor on the market at the time, and af so bad it's a waste of battery, etc); the comparison was hilarious, the nikon with kit lenses with in-lens motor (the only kind the d40 can handle anyway), and k20d with the screw drive kit lenses (18-55 and 50-200), it was like comparing a bicycle to a sports car.
decisiveness, focus tracking and so on are a different storry, and much harder to evaluate at a glance anyway, but please stop imagining speed-daemon rebels, pick up a rebel with the kit lens, and compare it with the k-5 or whatever you want from pentax which is less than a decade old, with the pentax 18-55, in any light, and you might be surprised.
