what are you taking a picture of that need more than a 10 stop filter?

Shooting in bright sunlight for architecture, and do not want to go more than f11 to avoid diffraction issues.

2400 euro for a 5D Mark III new or a 1 year old 1Ds Mark III, 1400 euro for a 5D Mark II... tough choice but I am gravitating towards the 1Ds III. I prefer the ergonomics and it will be meant for low ISO work, for the high ISO work miss 1DX performs just... purrfect.

Schneider Optics (B+W's parent company) makes a 100x100mm ND1.8 (6 stops), in their MPTV line (motion picture/television) - B&H link.  Note that they're Schott glass filters (they're the only ones that I know of who make glass square/rectangular ND/gradND, vs. resin.  The issue is see is that they're twice as thick as the Lee resin filters.  I know the Lee holder can take them with an appropriate adapter, but I don't know if you can use a 2mm Lee and a 4mm Schneider in the same holder at the same time.

Just found a HiTech 4x4" resin ND1.8 that will fit a Lee holder - B&H Link.

Hope that helps...

Thank you for the help Neuro, Hitech have a 6 stop one, I can stack that with the Big Stopper since it comes with a 1.5 mm gasket fitting the Lee system. Lee themselves are also considering releasing a 6 stop filter in the next 3 months or so they tell me. Hope vignetting will not be an issue, but I use an 82 mm ultrawide adapter, so hopefully not.

Quick tip: get a set of Lee ND hard grads instead. That way, you can turn the grad upside-down to use it as a ND filter. However, the hard ND resins only go up to 1.2 (4 stops) max, I believe. Still, you could stack (:o) them.

Then you have a set of hard grads (very useful) and NDs.  ;)

P.S. I have only tried this with a full-frame sensor camera and focal lengths below 70mm. But I imagine it would work with any combo.

Have a set of 1, 2 and 3 hard grad NDs, but not sure it would work out.

I've got some tests with several ND filters (LCW Fader ND, Tiffen screw-ins, cheap resin filters) over here:
http://www.similaar.com/foto/lenstests/lenstestsn.html

My conclusions:
* sharpness is not an issue, even on a D800, as long as you use decent filters (no fader, no cheap resin)
* color cast is an issue, but it's relatively easy to fix (at least with my filters)
* stacking filters is not as bad as people think

Would you classify Lee and Hitech as having "cheap" resin filters?

Why this reluctance to ship to EU from UK? I wanted to get a Gitzo and a 50 mm from eBay and yet no one wants to ship any from the UK to Malta, a proper EU country with straightforward shipping.

Brilliant, a thread with a particular issue I am having... I need a square filter ND, 6 stops, to stack together with the Big Stopper to get 16 stops... Neuro any idea? Lee make 3 stop NDs, but I guess stacking a 10 stop Big Stopper and two 3 stop NDs would be overkill in terms of vignetting. Hitech, Cokin or BW make a 6 stop 100 mm square filter anyone knows?

Owning a Lee Big Stopper, I would like to stack more 100 x 100 mm filters to get even less light filtering through. Anyone can elucidate me on what options exist for 6 stop filters, only proviso they have to be square 100 x 100 mm to fit the Lee filter holder system.

Sirui are a relatively unknown brand, but they have exceptionally good tripod heads with a panoramic function. Check their K-30 or K-20 heads.

The 1DX I love, but I need a second body since it is too messy having to keep changing lenses from telephoto to ultrawide each time.

So general consensus seems to be ... steer well clear! Although that A1 looks lovely, but with fungus in the picture, that is a no go. Would love to use them at some point, but was looking more at collecting vintage bodies rather than use. What would anyone suggest as a vintage camera, whatever make, which has value as a collectible?

Anyone have experience with vintage Canon camera bodies from the late seventies early eighties era? Have a person trying to sell me a Canon A-1, Canon EX Auto and Canon T-50, all with respective lenses and in working condition film cameras, although he says some have fungus! Is their total worth worth the 200 euro asking price for all three of them seeing they will need cleaning?

Good information, you probably have a point that paying that amount of money for a 5 year old body released in 2007 does not really make sense... but waiting for a high MP count to ever appear from Canon will take quite a while...!
