Is it common that this lens makes noticeable noise during auto focusing (especially in af-c mode when it is difficult to focus)?

Hi, for this Sony lens SEL24F18Z, it is a normal operation for having some noise during auto focus. -Ely

I haven't noticed noise from the shutter, but there is some noise when the camera is turned on - I suspect from the sensor cleaning unit. Noise, however, is not usually an issue since I shoot mostly outside.

I've been using the camera for about 3 months or so and was hesitant about using the auto focus/auto exposure because my last Canon video camera not only made noise, but it continuously unfocused and refocused throughout recording. I switched to all auto mode just to "see" how bad it was and haven't gone back since. I use Premiere Pro editing software and the audio is clean (we run a small soundboard and there's a tiny bit of hiss from there that the denoiser filter removes completely). But we hear no camera noises at all.

I can't say that I have. The lens I use this adapter on does not have an Auto-Focus. Having said that the AF on my other lens has been acting a little strange lately.

No, I love this lens. I havent noticed excessive vignetting, and it works fine in continuous auto-focus. I am shooting with a Nikon D300S and have been using the lens for a couple of months.

To the best of my knowledge all non-STM motors result in lens noise while recording. The other review sounds like they were confusing the full time manual (FTM) focus feature of most USM lenses as somehow creating more noise than non-FTM lenses, not true. STM lenses are specifically engineered to have a slower more controlled AF while recording video, thus producing less noise than all other Canon lenses.

I would like to add to the comment made about the AF. Yes, it's a little loud going back and forth a little. I knew that going in and in fact Lumix warns of it on the older version, and I would not suggest this lens for video. I use it for still photo's on a Lumix and have no other issues. Perhaps the new version is not as so?

I haven't notice any loud motor noise when my lens focuses, just a little click noise when the motor starts or stops when focusing. It's about the same as my 24-120 mm or my 70-300 mm lenses.....not much Hope this helps.

Cheryl - some time ago I bought a "slightly used" lens from an Amazon vendor. It would not autofocus in live mode on my Nikon D5100. For some time I thought this was a problem between the camera and lens, but I finally consulted Tamron and they said it would need expensive repair. Amazon was gracious let me return the lens. In manual focus it took wonderful shots - but I have no way of knowing if you are talking about this same particular lens.

I just received my SD970 and noticed that it does make a chattering/hunting noise when in full-Auto mode. It seems to do this for 3-4 seconds until the camera and the scene are stable.For whatever reason, it doesn't do this in "P" mode even though I set it to AI-Servo Auto-Focus. So it must be more than just the focus causing the sound.There is a very slight reference to this in the owners manual -- but wanted to verify this is normal operation.

Mine does the same thing. Lens seems to work just fine. Probably has a friction clutch which permits the focus ring to turn past the stops

I have to return mine, 'cause there was this "shifting" of the image in the viewfinder when pressing the shutter half-way down. I've learned that it is the autofocus locking-in on the target or subject and maybe that is the "clicking" sound that your hearing. I have a Tamron 24-70mm f/2.8 VC and 70-200mm f/2.8 VC in Nikon mount and I dont have this issue. Anyway I decided to return it because the "shifting" of the image is too visible for me and feel like the QC is subpar on this lens.Hope this help.

mine is ok,but if you hear a noise when you have it on autofocus mode,that noise is normal(its like ka,ka,ka)

yes, it has an auto-focus, but at times, it cam be sort of slow, but overall, it is a very good lens.

It is a noisy lens, but so is the 50mm f/1.4. When back focusing it sounds a bit like a small electric toy car (it doesn't have an ring ultrasonic motor) and when locking focus there is a small click like sound. That's perfectly normal.

Hello Brian. I've had this lens for four years now, and while my copy has been beset with build quality issues, I can't complain about autofocus. It's not as fast as some of the newest SSM lenses, but it tends to be quick and accurate.

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.
