jackbaty Posted December 31, 2020 Share #1 Posted December 31, 2020 Advertisement (gone after registration) I apologize in advance for the novice question(s). I don't shoot video but thought I'd try with my newly-arrived SL2-S. Right out of the box, with the APO-Summicron-SL 35, I recorded a few seconds of my dog as a test. The only setting I changed was ISO. There's a loud focusing "chatter" during the video. You can hear it here: https://youtu.be/hxXu5rgaFRg I don't yet understand anything shooting video but I'm guessing there's something I'm missing, because this doesn't seem right. I noticed a similar noise in photo mode when Pre-focus was enabled, but I don't think there's the same Pre-focus option for video. Thanks for any advice.

jackbaty Posted January 1, 2021 Author Share #7 Posted January 1, 2021 (edited) Advertisement (gone after registration) Thanks for helping. I've tried all the same settings with the Sigma 24-70 attached and it's completely silent with that lens. I would find it hard to believe that the noise level I'm hearing in the Summicron is acceptable to anyone, especially considering the way Leica positions the SL2-S camera system as a hybrid. I'll keep testing to see if I can pin it down. Edited January 1, 2021 by jackbaty Link to post Share on other sites More sharing options...

BernardC Posted January 1, 2021 Share #9 Posted January 1, 2021 Have you applied the latest lens firmware updates? Some here have reported that it cures lens chatter. You should also try different focusing modes. There's a separate thread here that covers the different modes and how they work. It sounds (literally) like you are in the mode where it continuously micro-adjusts focus, which isn't ideal for video. If neither of these two options helps, your dealer can swap the lens.

When I have used AF, though, there has been no audible focus noise at the time, but I haven't listened to the recordings for it. Link to post Share on other sites More sharing options...
Slender Posted January 1, 2021 Share #11 Posted January 1, 2021 The AF in my SL 24-90 is totaly silent for example, but in video and continuous, the internal mic or external shotgun mounted on top will pick the sound of the (one, single) moving lens nonetheless, in a quiet setting. Not gonna be an issue in a normal, busy soundscape, interview, streetscene...etc, or with a mic further away from body, or in MF. Link to post Share on other sites More sharing options...

I'm finding that the noise is more prominent when the lens is hunting for focus on, say, flat, low-contrast surfaces. It's a little discouraging that I hear _nothing_ while using the Sigma zoom, though. I will keep testing and see if it's a problem in the real world. I'm surprised that the lens makes such a racket shooting videos but also concerned by the noise it makes in stills mode when "Pre-focus" is enabled. I can actually feel it vibrate as well as hear it. I didn't expect to mount such a beautiful (and expensive) lens and have my first thought be, "Eww, what's that clunking noise?" The "simple" suggestion to go try another lens at a shop is a good one, but I'm 3 hours away from anywhere I could do that so I'm trying to work out whether it's expected behavior or an actual problem here at home first. My first impressions of the actual images from the 35 are that they are amazing. Link to post Share on other sites More sharing options...

In video mode, the autofocus is slow and silent. The only noise comes from the ibis, which is pretty silent as well. I think something is wrong with your camera or your lens.

jackbaty Posted January 13, 2021 Author Share #16 Posted January 13, 2021 Following up, here is Leica's response... Quote The noise behavior of your SL lens is normal and varies depending on the model, focal length, camera used and exposure conditions. This can not be improved. So I'll just have to live with it, I guess. (I did replace my copy of the lens, but it makes the same racket). Link to post Share on other sites More sharing options...
Anakronox Posted January 14, 2021 Share #17 Posted January 14, 2021 Try turning off pre-focus as that can cause noise in stills mode. Link to post Share on other sites More sharing options...

I did that first thing (once I learned there was such a thing :)) and it really helped with stills. Link to post Share on other sites More sharing options...
