No man you are correct, Canon has AF in lenses and all its EF and EFS lenses has it unlike niks where you need to carefully choose an AF lens which is having an independent AF mechanism.In fact this is one of the reason in lens price difference in Canons, some lenses have high speed quite motors(USM III) required for speedy silent focus like in macro shooting so they cost more than others like kit 18-55 which are slow in focussing, even 50 mm f/1.8 is zippy in focussing, at times when the lens is in AF mode and hunts for focus; i feel ki lens ghum ke bahar hi aa jayega:bleh:.

check out some of lens photos, you will see that it has an AF/MF switch
The price is less because:
1. It's a prime so no moving elements inside which in turns make the construction simpler which in turn bring down the price.
2.The mount is made out of plastic instead of metal as in some other higher order lenses.
3. Construction is really simple and bare minimal things are given, not even a distance scale which again helps in reducing the cost.
That's why it is so sasta and tikau.:hap2:hyeah:

why do you say, the 50mm f1.8 is useful at f2-f2.8, and not at f1.8 itself?
and would the same happen as well on the nikon 35mm prime?
Simply because f/2.8 is the sweet spot of this lens, you can use it at f/1.8 also without issues esp on 1.6x cameras but at f/2.8 it delivers it's best.!
about nikon 35mm, you need to see its performance graph to see at what f point it performs best. not necessarily same as canon lens.
P.S Sorry for such big post guys!!essay writing ho gayi..
