Question about long exposure and filters

[shutterwideshut]

As far as filters go I'm looking at Singh Ray and Lee. The warming filter and ND reverse filter for starters.

If you are looking into stacking filters then the good combo to consider for a start would be: Cokin Z-Pro Holder + Singh Ray LB Warming Polarizer(Z sprocket mount) + 0.9 Singh Ray Reverse ND Grad Filter. For the record, Lee doesn't produce any Reverse ND Grad.

And yes, there will be vignetting at focal lengths wider than 24mm on FF. 

Watch this comparison by Landscape Photographer Darwin Wigett to know the reason why you should consider the Cokin Z-Pro Holder instead of the Lee Filter: http://darwinwiggett.wordpress.com/2011/06/28/lee-holder-vs-cokin-z-pro-holder/

Looking to do more landscape photography. Shooting with a 60d at the moment and looking to buy a 17-40 in a few days. Will be moving to full frame soon so the EFS 10-17 is out for me.

As far as filters go I'm looking at Singh Ray and Lee. The warming filter and ND reverse filter for starters.

The 17-40 is 77mm thread, so do I need to get the regular screw in filter and screw in adaptor ring to stack filters that way? Or will this cause vignetting?

The filters I got, I can just stack them on each other, no adaptor rings or similar. Vignetting, yes in the wide end. I had some serious vignetting at 24 on my 24-105. I had only two filters stacked.

thanks

At what mm do vignetting start? And what filters are you using.

I've read on another forum that the 77mm thin mount warming filter doesn't cause vignetting? But it doesn't have front threads though. And will probably cause uneven polarization as will.

I use both the Lee Filter and SIngh Ray Filter System. At focal lengths wider than 24mm on FF, vignetting will start but this can be corrected easily on PP. Here are some of my filter combinations for shooting long exposure:

At 10mm on a cropped sensor camera, vignetting is obvious but I don't mind though:
