Of course there will be noise. It's the focusing gears. You would need to have a very high-end lens for focusing to be almost silent.
for budget lenses, you can't expect too much I guess. But really depends on how "loud" the sound is.
Nevertheless, we tend to be slightly more sensitive to anything we bought second hand.
Only 'second hand'? Some people here freak out over dust inside a newly purchased lens, expecting the level of cleanliness one can find in semiconductor production facilities... Others demand a consumer camera model with absolutely zero shutter count. :dunno:Nevertheless, we tend to be slightly more sensitive to anything we bought second hand.
This lens is known to be loud and dusty, so nothing to worry about. Despite of that, the image quality is excellent. Get a EF50mm f/1.4 USM if you want silent AF.
Besides, this lens is made of plastic (except for the lens elements), so expect it to break if you drop it... :sweat:
lens in general for canon, if the front berrel rotates in a circular motion it will most probably have noise
2 cents.
Canon basically uses 2 different kinds of motors in their lenses. The micro motor and ring ultrasonic motor (USM). 50mm f1.8 uses the cheaper micro motor and this tends to have a bit of noise when focusing.

There are also different kinds of USM. The 50/1.4 drew the short straw and landed up with the noisiest one... it's not much quieter than the 1.8. In fact it's one of the very few (clearly) audible USM motors.
