I was hoping to be able to use my Cokin ND8 on my Sigma 10-20mm, but when I attempted it today you can plainly see the sides of the filter holder at anything below 14mm....oops!

Is there anyway around this (i.e. a special filter holder?) or is it just a downside of such a wide angle?
 
You should see the vignetting at 10mm then :(

I think you can hacksaw two of the furthest away slots to reduce this happening, but whether it'll stop this completely, I'm not sure...on balance, I doubt it.

As for perhaps using a different filter holder and still using the Cokins, I don't think that'd work either; I think it's been discussed fairly recently..

Most recent software can rid images of the vignetting effect, or of course you can crop the edges of your images...

It's the X or Z pro system for you.

Kerching!

Aha! I think it's the "P" system I have at the moment.

I asked if the holder was fine for the Sigma 10-20mm in the shop and he said yes!

...so is X or Z pro Cokin? ...and I assume it's more expensive! are we talking Lee prices?

...found this on the Cokin site http://www.cokin.com/ico6-WIDE-ANGLE-HOLDER.html

it says it helps down to 20mm but that's 35mm, not sure what this would acquate to on digital.
 
At 10mm the field of view is so wide that you need the physically larger filter size of the X pro series, the Z are mainly used for motion picture cameras (or is it the other way around?) either way they're both very expensive.

...just a bit! like watching a widescreen DVD on a normal TV, but turned 90 degrees! :D

Thanks sprog, might have to add the X pro to the wishlist then :(
 
I chopped off the two outer slots on my "P" holder, works a treat now... There are also proper wide angle "P" sized holders, with only one slot available....

:lol: The 1970s letterbox format has returned to the world of cameras!

I have the Lees and can't fault them, either for neutralness or the design of the holders/adaptor rings.

Granted, a lot of dosh (I only have two filters) 2 stop ND and 2 stop hard ND Grad and will need a full set of soft and hard grads to give maximum options but they are well worth it!

Would be interested to see whether the Z series would be the answer here.

Indeed it has! :D

Well I too have a "Lee Starter Kit"...as was when I bought it several years ago, it has a filter holder and a ".6ND G H" filter. Problem is the adapter ring is broken, can you buy the bit that clips into the holder and attaches to the lens?

Not sure if I'd need another ND, I seem to recall people saying the .9ND was the most common filter?

...Denied!!!! :bang:
 
If the holder is the same as the one in starter kit I have, then you can as my adaptor ring is a metal one..

Does your holder have a brass knob which lifts up, then push the adaptor ring in then release the knob? Sorry, I have no idea if it isn't the same as mine, as have only had my Lees a few months...

yes thats the one, there is a brass knob which pulls out. I think the bit I need is simply the adapter ring, but Warehouse Express dont have any stock!

I've had it for years, but used it only twice! :lol:
 
If it's the 77mm one you're after, I had the last one from Warehouse Express IIRC...

Ermm....Robert White www.robertwhite.co.uk have loads of them in stock (I know that for definate) as rang them before buying from WEX, cos I saved on postage by collecting in person.

If you factor in postage, RW works out a £1 dearer...their customer service is extremely good!

Yes it's the 77mm! I'll take a look at Robert White then :thumbs:

Which Lee ND do you have, from what I see theres three you can buy in a set but its about 140 quid! I've got the 0.6ND.

I use a Sigma 10-20 on my Nikon & use cokin P filters with the cokin P Wide Angle adapter. I get NO vignetting at all even @10mm. Just make sure that the adapter ring is placed on the lens & not on top of a skylight/Uv filter.The Wide adaptor only has one filter slot compared to the normal one which I believe has three.

..cheers Toonie, I noticed that on the Cokin site about an hour ago :)
 
0.6 is a 2 stop grad on the Lees and is the most commonly used on DLSRs IIRC.

I also have a hard 0.6 grad, plus a 0.6 pro glass ND in the kit, so I guess I'm gonna go the same way, especially with a set of softs, which I presume will work out slightly cheaper buying the set...

Toonies suggestion might be the way to go for saving money, but the adaptor ring (Lee) will set you back about £18 and will mean you could use an undoubtedly better quality filter.

I'd definately check with White's that the older filter holder is compatible with the metal adaptor ring. They're very clued up and should be able to tell you straight away..

Thanks Markta, I've just popped them an e-mail over, lets see what they come back with. :)
