Hi Sony Alpha Forums,

 

I would like to ask. During startup/turning off the camera with Sony 70-200 f/2.8 GM lens attached, is it normal to hear a short rattling noise from the lens?

During auto-focus, the lens doing just fine. But when start-up/turn off, I heard a short vibration/rattling noise from the lens.

 

The noise is similar like the rattling noise when Sony Alpha is in self-cleaning mode.

 

From what I observe, it's a mechanism inside the lens which open/close the aperture.

 

Is this noise normal?

 

Looking forward to your advice.

Hi,

 

I bought the same lens a week ago and it has the same noise. It's like a short rattle on startup/shutoff. I've also noticed that if you turn off exposure preview in camera, it rattles everytime you focus - wich is kinda annoying. When exposure preview is on, it only rattles during startup/shutoff. 

Another thing is that it focuses kinda slow when in AF-S mode. I think this is because it only uses contrast detection in that mode. When in AF-C, it focuses very fast. 

 

I use mine with the A7RII.

      ISO Bracketing

      By Richard A · Posted

      ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.

      ISO Bracketing

      Thanks for the information. Since my original post, I did some "experiments" at different iso settings. Best results were obtained at iso 320, and then increasing the exposure by four stops in Lightroom. The biggest difference compared to using a higher iso was that there was detail in dark foreground areas, while at high iso the dark areas were blocked. This is consistent with articles I've read about ISO invariance.
