Question for 12-24 owners out there

Hi everyone,

I have a question for 12-24 owners (tho I think I know the answer already). I just received my copy which I ordered used from KEH camera. However it sounds like there is something loose floating inside the lens. When handling the lens I hear something moving inside it. The lens looks great, I don't see anything when looking thru it and it takes pics no problem. It doesn't sound right tho. Does anyone else have that with their 12-24's? I really was looking forward to this lens but don't want one that's broken obviously. Is that normal with this lens? Any help would be greatly appreciated. Thx.

Rick

Same here, no noise from inside the lens.

I have this lens. When you rattle it, there is a very subtle noise but I think it is due to the zoom/focusing ring rather than a floating element inside.

Could be one of the rings, the aperture blades, or in worst case, a glass element. And I hope you aren't mistaking the normal camera's SR clunking for the lens. Dismount the lens, but don't shake it too hard.

Take some photos, do they show decentering (one side being blurry) at any focal lengths? Do the aperture blades close correctly?
Also, is the sound only heard in a very quiet room if you put your ear to the lens, or is it loud? You shouldn't shake the lens very hard either way.

Thanks to everyone for their responses. It was not the SR of the camera because it is happening when the lens is off the body. It definitely doesnt sound right. I have contacted KEH and they are setting up a return, I just wanted to use it this weekend oh well. On a different note (and maybe I should start this in a new thread) anyone compare it to the 16-50 as far as IQ? That was another lens I was considering as I want a WA. I was drawn to the extreme WA at 12mm but 16 is pretty wide too and just wondering anyones opinions if you have used the two of them. Thanks again to all.

In my own testing I found the DA* sharper in the range they have in common but the DA 12-24 has much less distortion at 16mm.

There is a huge difference between 16mm and 12mm. Since you had your heart set on the 12-24, why not just order another one from KEH (if they have one)? They are very good about warranty and returns.

I had the DA* 16-50, but ended up selling it to help pay for the 12-24. 16mm just wasn't wide enough for how I want to use it. I find my 12-24 better in overall IQ than my 16-50 was, but there is kind of a crap shoot with the 16-50 as far as getting a good copy (not talking about SDM issues here).

Everyone's needs are different, but for myself I have a great combination now - the 12-24 plus the DA 35 2.4 prime and DFA 50 2.8 macro.

Try another 12-24 - it's a fabulous lens!
