Hiyas,

So I have been looking at getting a new lens, initially the Canon 10-22, but after much reading it sounds like it cannot be used all that successfully with my filters, I have Cokin P's and it will get a lot of vignetting.

I have read many reviews on how good the lens is. I think I want to to be able to fit more in the photo, but now I am not totally sure and am considering the Canon EF 17-40mm f/4L USM instead, this will work well with my current equipment Canon EOS450D, Kit 18-55, Kit 55-250 and filters.

May I have your suggestions on what you think, my brain is hurting

I mainly take Sunrise,Sunset and Seascapes

Maybe I'll just stick with the kit lens a little longer and take a heap more photos and perhaps it will become clearer as well.

Thanks

You can use photoshop for filter effects or you could use the larger filter (holders) from Cokin. The point of a 10-22mm lens is the wider angle of view isn't it?

I find that the most valuable optical filters for a digital camera are the circular polarizer (CP) and a graduated neutral density (GND) filter. Of those 2, only the GND would have real value on a superwide zoom like the Canon EF-S 10-22mm, f/3.5-4.5 USM. Since a GND can also be simulated, or even improved upon, with a multiple exposure and post-processing with layers, even its value is situational (when only a single instantaneous image will do.)

The difference in coverage between 10mm and 17mm is enormous so the 2 lenses you mention are really used for different things, although the EF 17-40mm, f4L USM is a significant improvement upon the "kit" lens in overall image quality.

If you are happy with the overall quality of the kit lens you can achieve a wider angle-of-view using multiple overlapping images and panoramic stitching techniques. This would also improve the amount of detail available for a large print.

Lots of options to explore.

Another take on it .... After the light, the lens is probably the most important component of the whole image capture process. So, instead of buying a lens to fit the accessories you already have, buy a lens to do the job you need/want to do and buy any accessories you might then need to compliement the lens.

And, like Ziggy says, there's a huge difference between 10mm and 17mm. Much more so than between, say, 50mm and 85mm (just to select two common primes).
