Lee Filter Adapter for 'Wide Angle' Lens.

[Twombly Red]

Hello,

I have just obtained a Lee Filter Foundation Kit to use mainly on my Tokina 12-24mm lens coupled with a Canon 40D.

I now need to get a 77mm thread adaptor to fit the kit to the lens.

I wanted to ask if I would be okay with the standard adaptor without vignetting or is it neccessary to get the more expensive wide angle adaptor?

Regards,
Andrew.

Thanks for nowt. Just gone and bought the wide angle adaptor to find out for myself.

Only saw this today or I would have answered sooner!
Yes, you'll need a wide angle adapter. On my full frame body, I start to get some vignetting at around 19mm, using a 17-35mm lens and with 2 filter slots and a polariser ring attached. If the polariser is on as well, it becomes evident at around 20-21mm.
I would imagine this will not be the case with a cropped sensor until you reach a shorter focal length, but I wouldnt be surprised if there is still some vignetting at 12mm, depending on the number of slots you put on the front.

If you need a question answered quickly you need to post it on a high volume site like photo.net. Questions normally get answered within the hour i find depending on the time.

I find this site is more of a gallery.....its all about the pictures.....

Thanks Gordon, I currently use a combination of two screw on filters and do get some vignetting. Hopefully by having gone for a wide angle adaptor it will not be a problem. I have already conceded that I may not be able to use three filters but I do like to keep the glass in front of the lens to a minimum anyway.

Andrew.
