Re: Pany 7-14 on OM-D

It's all very obvious and easy Steve - literally less than a 5 min job to fit the holder and probably the same to cut the gel to size. Don't let that put you off.

The holder seems readily obtainable, so I'd hold off getting that until you have tracked down the gel from somewhere. (I think Tiffen sell them too)
Ebay might be your friend here as well.
I see what you mean about the filter, an Internet search has shown only one source in the uk: 'Sigma-Alorich' who do the Written 2A at £44.60 for 3"x3". Otherwise it's the likes of B+H state-side for $59.95 plus tax and postage.
Best from eBay was the 2B, but the passband might not be effective.

There may be others too. Maybe worth sounding out others to share?

Re: Pany 7-14 on OM-D

Thanks Bill, really helpful of you. I had a look at the spectral plots and from recollection the 2E should attenuate UV equally well. I'm happy with the price so will order I think - when I get to a secure link to change passwords etc for ebay.
Regarding the holder, I emailed Dkavs and received the reply: "Hi,
I am sorry but we do not supply component parts.
Regards, DKAVS".
Have you any further suggestions for sourcing the part?
Many thanks,
Steve

I phoned them, spoke to a friendly chap who took my order, credit card number and posted it the following day.

Re: Pany 7-14 on OM-D

When mounted on a Lumix camera all CA are removed by the process engine in the camera.

Re: Pany 7-14 on OM-D

I read somewhere that Lumix had a sensor mounted filter - in common with most, if not all, digital cameras - that had a cut-off frequency (wavelength) that attenuated UV, since the sensor is responsive to UV energy levels. If it's the camera-based process engine that is doing the business, why is it virtually impossible to replicate this process in LR?

Re: Pany 7-14 on OM-D

For anyone who is interested, for example if you own a Panny 7-14, I've just ordered a VXQ1911 'shading frame' from Panasonic UK for £14.42, delivered. Hoping to have it in my hands in 5-7 days. All I need now is Wratten 2A or 2E and I'm off.
An Internet search came up with the following supplier:
http://www.sigmaaldrich.com/catalog/product/sigma/f9265
I'm waiting for the 'shading frame', as Panasonic call it, then I'll be placing an order, unless something cheaper turns up beforehand.

Re: Pany 7-14 on OM-D

I now have the filter holder and the 2E gel filter is on order. Anyone have any thoughts / experience in cutting the filter to size?

The filters are easy to scratch, so first cut a piece of paper or thin card to the right size to use as a template. Scissors are fine for cutting the gel, but put a lint-free cloth underneath to stop scratches as it falls after cutting or as you pick it up. It might be worth using small tweezers to handle the cut piece to avoid finger prints too.

Re: Pany 7-14 on OM-D

Thanks Paul, it's like micro 4/3 surgery! I hope the end results pay off.
The lens output is fine in overcast conditions, meaning 90% of the time in the UK, it's just those occasions when the sun is out playing.

I think I'll form a sandwich card - filter - card, and cut. Keeping registration of all three could be my problem. I'll think some more whilst awaiting delivery.
Cheers!

Re: Pany 7-14 on OM-D

Another question please for those who have experience fitting the filter holder to the P7-14 lens, did you find the need to shim the VXQ1911, and if so by what amount, i.e. thickness? According to a 'how to do it' on DPR, it talks about fabricating a horseshoe shaped plastic shim of thickness 0.5mm, approx.

Re: Pany 7-14 on OM-D

Although there seems to be very little interest in modifying the P7-14, I add this user manual for the 8mm fisheye which provides the cutting guide for the gel filter to fit the VXQ1911 frame (see page 8).
