Fuji X-E1 and 35mm f/1.4 noise
Jul 29, 2013

Hello friends,

My 35mm works beautifully, but it is definitely not silent. When half-pressing the shutter, I can always hear quite loudly the aperture blades closing and opening when I release it (unless I'm already at f/1.4).

When I turn the camera on with the 35mm I can hear the same aperture blade noise. If I look inside the lens when turning the camera on, it will immediately stop down to about f2.8 or so and then quickly open up to f/1.4 (I usually leave it at f1.4), which is where the noise comes from when turning it on.

I also noticed that when half-pressing the shutter at any aperture other than f/1.4, the lens will close the aperture near, but not at the desired f stop, focus the lens and then quickly afterwards close the aperture a little more to reach the desired f stop.

Anyone else experience this too?

Cheers,

P.

Do you have the latest firmware for both the camera and the lens installed?

Yes, sorry I forgot to mention that everything is up to date.

Well, that removes that possibility. I do not have the lens but I believe earlier FW versions had chattering aperture blades. Hopefully someone with more experience has an idea.

If no one else can hear the noise I would not worry. You can always send it for repair.

The updated firmware just tries to ease in the change (e.g. by not making drastic changes in aperture too quickly), so that the noise is less noticeable. But unless the lens aperture blades themselves are a smooth, click-less type (such as the Voigtlander 17/0.95 and other cinema lenses), you are not going to eliminate noise completely.

Yes, and this is ridiculous, Fuji!

Yes, and this is ridiculous, Fuji!

Hmm I just tested this by pointing the camera at the window and focusing with various apertures, then pointing the camera indoors and focusing at various apertures.

Based on the test, I can form my hypothesis:

First of all, we know all mirrorless cameras must use the aperture to regulate the amount of light that continuously hits the sensor.

Second of all, we know that most, if not all, cameras focus wide open in order to accurately focus (i.e. too much DOF makes it harder to pinpoint the plane of focus).

Now, in the case of the Fuji X cameras, it seems to me that when the sensor is not overwhelmed by too much light (e.g. pointing inside the room), it focuses normally: it opens up the aperture wide open to focus, then stop down once focus is confirmed for the shot.

On the other hand, when the camera is stopped down due to excessive light (e.g. pointing at the window outside), it will still try to open the aperture up if you are stopped down; however, depending on the light levels it may or may not open fully wide open.

So... this is what appears to be happening and it seems reasonable behaviour to me.

Interesting. So mine is not an isolated case? This is how the 35mm lens functions properly?

It's generally not a bother and it works fine, but in silent locations it can be a little bit of a bother.

I like to choose song or album titles for my blog posts but in that case it fits absolutely perfect.

It's a machine. It's bound to make a little noise. I can't imagine a singe instance where it would be noisy enough to be a problem. I have strong doubts that anyone 10 feet away from the camera would even notice the thing firing.

Do you come from a P&S camera to the Fuji, or have you had other non-P&S cameras?  Just a question, don't read anything into it.

I agree, I was just wondering if this was the normal behaviour for the lens or if mine was faulty. Don't read too much into it.

OK, just trying to get an idea if Noisy is really Noisy Sorry for asking. I see someone tested the aperture movement like you have.
