Panasonic 7-14mm Filter

I just bought Panasonic 7-14mm. What are the possible filter solutions for this awesome lens?

So far I've found DIY solutions:

  1. Rubber gasket solution (ClubSnap )
  2. Hood solution (hkavmode )
  3. Rubber hood solution (RandomPhotog )

Professional (expensive) solution:

Is there any other options? I would love to use the 10-stop ND filter for this lens at 7mm.

Re: Panasonic 7-14mm Filter

The best solution seems to be the rear filter holder from the Panasonic fisheye. It is available as a spare part from Panasonic. AndersW has written about the conversion.

So is there a 10 stop ND filter that will fit that?

Gels provide about the most comprehensive choice of filters you can find. So, yes, of course. The strongest Kodak (Tiffen) gel ND filter available has a transmission rate of 0.01 percent.

Interesting. I didn't realise there was such a wide choice available. Ta for that link.

Does make you wonder why the manufacturers of these bulbous ultrawide lenses don't stick a rear filter holder in as standard, given that so many photographers still have a desire for using NDs.

Yes. I think it's self-evident that any lens that can't take filters up front should have the option to do so somewhere else, e.g., at the rear. In this case, Panasonic overlooked the issue when designing the 7-14 but recognized it later, when designing the 8 mm fisheye. What still surprises me is that they didn't grab the chance to just do what I did already on the production line for the 7-14: Add the filter holder they were already manufacturing for the 8 mm.

You are welcome. Yes, I know of the shipping-cost problems when buying from the US. But hopefully, Panasonic Australia will give you a reasonable offer.

Re: Panasonic 7-14mm Filter

My bank acct provided an excellent filter against the 7-14

Seriously, I preferred the Oly 9-18 and sold my 7-14. Reasons are several, one being protection of the front lens with a filter and another being small size. Plus I preferred the images from the 9-18, even though I use Panasonic bodies (GX1 & GH3)

The local Panasonic spare-part distributor quoted A$33, so it's not that bad.

Anders, how do you handle the gel filter? Tweezer? It looks very fragile and may get fingerprint/dust easily. Also, outdoor, the wind may blow it if I'm not extra careful.

Sounds like a very reasonable price.

Yes.

It looks very fragile and may get fingerprint/dust easily. Also, outdoor, the wind may blow it if I'm not extra careful.

The only "gel" filter (they aren't really made of gel any more) I have so far played with is an old Kodak Wratten 2A (bought used) that I have permanently fitted on my 7-14 (primarily to eliminate the purple flare problem this lens gives rise to on Oly bodies, with reduction of purple fringing as a welcome side effect). It is indeed very sensitive. I have learnt not to try to wipe anything of it, even with lens cleaning paper. That will just scratch it and ruin it completely. If you get a fingerprint in the wrong place, you either live with it or throw the piece of gel away. If you get dust on the filter, try a blower.

I haven't even tried removing and inserting the filter when outdoors. It's something I prefer doing at the kitchen table. But I am sure it's doable with a little practice. I'd try to find some place where I can sit down and where it's not too windy.

On the upside:

As I said, my "gel" filter (which I bought before I even knew whether it would work out as expected) is pretty old judging by the packaging (although I don't know exactly how old). The Kodak Wratten "gel" filters now available (marketed by Tiffen) are claimed to be more resistant to various problems as you can see here:

http://motion.kodak.com/motion/Products/Lab_And_Post_Production/Kodak_filters/wrattten2.htm

Once the filter is mounted at the rear, the likelihood that you will harm it is pretty small. The front of the lens is very exposed whereas the rear is not, especially if you take just a little bit of care when handling the lens.

It would be interesting to hear from those who have bought a new gel filter about their experiences when it comes to handling and sensitivity. It would also be interesting to hear from those who have tried switching filters in the field how they do it and how it works out.

As you can see here

Abrak is one of those who have been playing with ND filters in that holder on the 7-14. I asked him a question about how/where he mounted/switched filters but didn't get a reply (yet). Perhaps either of us could send him a PM with a reminder.

Thanks for posting that. Might be helpful for people elsewhere in Europe too. Do you know if they ship to other European countries and how much they charge?

Hi Anders,

I was hoping the same, but alas, they only ship within the Netherlands. However, I would be willing to help out with ordering and reshipping should someone be interested.

That's really the issue I have with rear-mounted filters. I played with them before when I was trying out a Sigma 12-24, but they're so fiddly. Not very ideal in the field.

Ideal in the field is a small, round filter about 50 mm thread size. Regrettably, those are not so commonly available with UWAs. So either you have a big unwieldy thing or a small fiddly thing. If anyone has a better solution, I am all ears. In particular, I am interested in the experiences and advice of people who have tried to change those small and fiddly things in the field.

Hi Ward,

A pity they don't ship elsewhere (but perhaps they're not allowed). At any rate, I appreciate your offer, not on behalf of myself (I am all set as you know) but on behalf of others. That's good forum spirit. I was helped a lot by others here (e.g., Mjankor and Optical1) when I was trying to work these things out and that's forum cooperation at its best.

Cheers,

Anders
