18-55mm DA WR SDM Questions!

DaveFish · 08-01-2013, 09:41 AM

Hello I am new to the site and just bought my first Pentax camera the K-01. When I manual focus in video mode the 18-55mm lens is queit, but after doing some interval shooting and quick frame shooting the lens will sometimes make loud shutter noise when zooming in and out in manual video mode. It doesn't always do it. It does it more before I press record and half the time it will not do it while recording. It mostly does it in the 20-18mm range. Sometimes the loud noise will continue through each number. Other times it is totally silent. Should I send for another lens? And is there any way to get the AF of the K-01 to be quiet!? Or am I just doomed in that department?

Thanks

Dave

I haven't looked closely at the newly released 18-55 WR, but my impression is this is a screw drive focusing lens just like all the other 18-55 models. The 18-135 WR uses an internal SDM to auto-focus which is nearly silent.

alright. That will probably be my next lens. What about the fact that sometimes the shutter is quiet while zooming in and out in video manual mode, but other times it is loud?

The 18-55mmWR is not SDM.

With the K-01, you will be limited by the ~~lack of external microphone plug and the~~ screwdrive. If you want to keep the K-01, use MF. (That is what I do.) Alternately upgrade to K-5-ii which has an port for external mic.

The K-01 does have an external microphone connector.

But still, either use manual focus, or get a lens that focuses silently if you're into video, IMO.

I thought the K-01 has an external mic jack? Mine does. I am still wondering why sometimes my lens is silent while zooming in and out in manual video mode and other times it makes what I assume is shutter noise, especially around 20-18mm. I am pretty sure it says SDM on the side of my lens. I will look again. Thanks for the responses guys!

Your 18-55 is behaving normally, it's a screw-drive lens. If you want silent than either manual focus or an 18-135 or other electric motor lens ( Pentax Sdm or Sigmas silent lenses).

Adam, thanks for the correction. I have a K-01 for 18 months and I did not realise that it has a mic port.

Alright sounds good to me, thanks. But still I am using manual modes and it is sometimes loud and other times it is quiet in manual video mode. It used to always be quiet then I did interval shooting and now sometimes the shutter is loud while zooming in and out in manual video mode while recording. I need to know if this is a defect, so I can send it back.

DaveFish · 08-01-2013, 10:42 AM

People are saying it should be quiet in manual mode. My lens is not always silent in manual video mode. Sometimes it is loud sometimes it is silent. That seems odd to me. This is my main concern, Is the lens defective? Thanks.

Are you sure it is not the aperture that is making noise?

The shutter on the camera is not going to be making any noise in video mode, while zooming, focusing, etc.

I would check to make sure that the aperture tab on the lens is not bent. It could be that it is not catching right which could make it make noise.

I totally agree that it is the aperture. That makes perfect sense now that I think of it. I have no idea on how to fix the perture tab in the lens. I am new to videography. I dub some videos with music, but not all, so I need this lens to be consistent. Should I send for a new one. I bought it from Adorama. Should I contact them or Pentax themselves?
Thanks for the response.

Thanks for the response.

Can you take a picture of the back of the lens and post it?? If the tab is bent, it should be pretty apparent.

If it isn't bent, it could be that a screw has come loose inside the lens.

I will upload a pic, but honestly if it is already acting up and I have had it for only one week I want to get another lens sent to me. And I want Pentax to pay for return shipping. Who should I contact to get a new lens? Adorama or Pentax?

I would contact Adorama. Will probably be much faster.
