I bought this lens and have a couple of questions (in separate posts)1. The focus is very noisy. Is this the nature of this lens?

Mine is not what I consider "very noisy" I can hear it but it is certainly not distracting in any way

Are you happy/satisfied with the one you've got? I'm not sure how you can tell but I'm sure there are those who know. My opinion is "if it aint broke, don't fix it". That being said, I am very satisfied with this lens and would highly suggest it.

Really quite Good. This is an excellent lens. I still have mine. Maybe the photos I took with it are still on http://amazon.com. Check out Kurtmunger for excellent review of this lens.

Yes I too bought this lens not too long ago (under a year) noticed the sound immediately however I expected that heading it from many sources, what troubles me though is that it's been only 6 months and I've had to send it in for service because my auto focus motor failed.

I have not used this lens extensively with video, I'm a stills guy myself, but I will mention that it is very noisy when it focuses. If you're doing video work you likely have an external mic in which case this may not be an issue, although even with that it might pick up lens noise if the mic is mounted on the camera. When I used it for video the image was fine but occasionally it was slow to focus and the sound from focusing was picked up from the built in mic as I mentioned.

It is a great lens. Focus can be touchy so i will switch to manual when photographing people so as to get exactly what I want crisp. The 1:4 gives gorgeous depth and beauty to the photos although with my profession ( newborn photography) I will try and shoot around a 2 to get a bit more in focus

It's a very good, an excellent lens for low light shootings. It's manual focus , and on f 1.2 it's quite soft, though you can find the point of sharpness on the photo, but from f1.4 it starts to be sharper and more interesting! Happy New Year)))

Hi, I don't find it anymore noisy than the majority of motorized lens. You can always turn of the servo and focus it manually, if wanted. How often are you close enough to a bird or animal with a 300mm lens that a slight motor sound is going to effect things?

I'm still shooting with the xt I bought in May 2005. I shot with the kit lens for 6 months and then purchased this $70 50mm lens. I use this lens all the time and it's my primary portrait lens. I own several L lenses now and I still use this inexpensive lens all the time. Eventually I'll replace it with the 1.4 or the L version but until then, I can not say enough good things about this lens. Negatives are that the auto-focus hunts in very low light, it's noisy and it's built like a toy. On the other hand, I've taken it around the world twice and been shooting with it for 3 years and it still works like a champ. I'm still shooting with the xt I bought in May 2005.

Is the camera constantly trying to focus? The only motor I can think of is the one that moves the lens. Try it standing in a stationary position filming or photographing something that is not moving - like a tree trunk. If you don't hear any sound because the lens doesn't have to move to refocus, then I would guess it is the lens motor. I didn't like this camera personally and ended up returning it.

This lens is a little noisy compared to Canon USM lenses, although not as much as an older Tamrom 17-50 I use with a 40D. If any doubts, you can always go a camera store nearby and try a display Tokina 16-28.

I've been using this lens for several months now and I do not hear such a sound as described. You should probably have it checked out.

This is not a stm or usm lens, so you would expect some level of noise. However, Not as bad as some of the older ef lens. It is still pretty decent.

I haven't heard this noise on my lens when focusing. Are your images affected in any way?

The first two answers are spot on. I bought this lens because it is far less expensive and I use a tripod most of the time.

I have the same equipment. The situation you describe is not normal in any lens mounted in any camera. But this combination lens/camera use to do it. Put the lens and the camera on manual focus, because the autofocus in this lens on this camera is a nightmare. But in manual mode, this lens is pristine, wonderful.

It's a very good low light lens, however if you use a F/2.8 aperture be very careful with your depth of field. Depth of field is very shallow with that large aperture. Stop it down to f/4 or more if possible.
