Hi

I have a 37mm adaptor (KIWI LA-37/LX7(B) – supposedly equivalent to Panasonic DMW FA1 model), and a B+W 37mm F-PRO CPL.

My problem is that it is not possible to completely screw the CPL. It seems the inner part of the filter (the rotating part) is in contact with the lens barrel, so that the CPL will not screw correctly and the filter will not rotate.

I also have a 37 UV filter and have no problem with it.

Any idea ? Did I bought the wrong filter (or adapter) reference ?

Thank you in advance for your help

Regards

David

Hello David,

I encountered exactly the same problem with my filter adapter. One or two others in this forum have had the same problem. Read on...

I purchased the DMW-FA1 filter adapter about a week after I obtained my LX7. I screwed in...
Pictures would help.

Can you mount the CPL over the UV filter and make the CPL work properly?

Hello David,

I encountered exactly the same problem with my filter adapter. One or two others in this forum have had the same problem. Read on...

I purchased the DMW-FA1 filter adapter about a week after I obtained my LX7. I screwed in my B+W 37mm circular polarizer (exactly the same as yours) that I had purchased for my m4/3 system. When the polarizer was screwed in properly, it would bind when I tried to rotate it. You are correct when you comment that the back of the polarizer is rubbing against the front of the lens collar. I tried a Heliopan at my local camera store with the same disappointing results.

Solution: I purchased the Lumix DMW-LPLA37 circular polarizer. It's the one mentioned in the LX7 owner's manual. Problem solved. I paid $63 USD at ShopPanasonic.com. I see that they are on Amazon for $70 to $78 right now. I was annoyed that I had to buy Panasonic's filter, but one of the reasons I purchased the LX7 was it's ability to accept a polarizer. So there you go.

Do not purchase the LPL37 circular polarizer. You want the LPLA37, which is the thin one which prevents vignetting on the LX7.

Oh, and when I'm not using the polarizer, I use a B+W MRC 37mm UV filter to protect the lens. Works perfectly. The new Hoya HD2 filters look interesting too. I don't know if the Hoya 37mm HD2 circular polarizer will bind on the LX7 or not. It's pricey though, around $87 USD.

Thanks a lot, Jim

Problem solved. In France, the panasonic reference is a bit pricey, so I will perhaps try the hoya. it seem thin enough, so it may work properly.

Are you saying," the HOYA HD2 CIR-PL 37mm fits as well as the Panasonic DMW-LPLA 37mm?"

MERX2006´s question has not been answered.

He/She asked, " Are you saying," the HOYA HD2 CIR-PL 37mm fits as well as the Panasonic DMW-LPLA 37mm?" "

My additional questions: 1. Are there HOYA HD2 filters? I only know HOYA HD filters.

2. First the HOYA HD CIR-PL 37mm filter has to fit. Secondly will there be vignetting?

Many thanks in advance for answering.
 
I have a Hoya HD2 Circular Polarizer filter mounted on my LX7. Works perfectly, doesn't bind, rotates easily, no vignetting. Adapter is the standard Panasonic DMW FA1

I also have a Hoya HD2 "Protector" filter. Also fits perfectly.

However, I can't stack the Polarizer onto the Protector without some vignetting.

I found that the Hoya filters are tricky to thread in and out of the Panasonic filter adapter, so I bought a second adapter. Each filter stays mounted on its own adapter and I swap filters as a filter/adapter set when I want to change between them.

The standard Lumix lens cap fits on either filter. I attached a tether cord by drilling two tiny (1/16") holes through the edge of the cap.

I carry the LX7 in a vertical magnetic-flap case, found on ebay. This looks exactly like the one I bought, but may not be identical: http://www.ebay.com/itm/like/121214285123?lpid=82 The case fits like a glove, with either the Protector or Polarizer in place. It also fits with the protector and lens cap, but with the polarizer and lens cap it's a bit too snug--the flap will barely close.

To get the fit perfect, I had to punch a small opening into the top of the case for the strap lug to protrude through. Rather than threading the strap through this hole, I just fold it over and let it dangle.

However, the filters are so easy to clean and have such a hard coating that I have dispensed with the lens cap, facilitating quick one-hand deployment from the case.

Hi

to schluchtenscheisser:

Yes, it seems to be a filter (google is your friend) :-)

http://www.amazon.com/Hoya-8-Layers-Multi-Coated-Repellent-Resistant/dp/B009IVD7AM

I was planning to buy this filter but did not have opportunity to do it. If you look at the previous link you will find it seems to be as thin as the panasonic PL filter. So it "should" be OK.

to MERX2006 :

sorry I didn't see your question, but this is an old thread ... m4/3 forum is very active and threads tend to disappear in 2nd page very quickly

Kind regards

David
