New 10-22mm f/3.5-4.5 shots

gluwater

Just got my new lens and here is what I have done with it so far.




Tthe first shot was taken with a Tiffen Cir. Polerizer and there is some noise on the right side as the sky gets darker. This is the first polerizer I have used, should I expect that or maybe just don't use it in darker settings?
The second shot is Howard the Bull Dog mix. It's not the best shot but one I like the most. Only slight post processing because my computer is acting up and I can't deal with it right now. Hope you like.

Which polarizer model?
First pic might have some vignetting at the top right corner, or at the least, some light fall off.

Wondering... the Tiffen circ. polarizer you got - is it one of those super-thin models without the threads on the outside? Do you get any vignetting around 10mm?

I've got the same lens with my 20D, and have hesitated as yet to pop the big bucks for a 77mm, and I'm searching for opinions. I do know they are more effective at 15mm and up.

Thanks!

I can't remember off the top of my head about the pol. lens. I just moved over the weekend and therefor don't have internet access at home so I'll check and try to post from work tomorrow. If I remember correctly this picture was taken at 10mm, I'll have to check the exif. I have some others taken in brighter light and between 10-22mm, I'll have to take a look at them and let you know. I'll try to post some more pics later this week so you can see for yourself.

One of the problem of using polarizing filters with ultra wide angle lenses is that you will get variations in the darkening of the sky due to variations in the polarizing effect across a large angle of sky. The polarizing effect is most pronounced at 90- degrees to the suns axis, and drops off away from there, so with extreme wide angles you can get dark or light corners independent of vignetting due to a thick polarizing ring that acts like a lens hood that is too small.

perfect explanation, pf!

Very much thanks again, guys. Yes, I knew about the effect fall-off at the wider angles. I'm more interested it using a polarizer on it at medium-wide settings for water and glass reflectability reduction. But I am also wondering about the vignetting (or actual filter ring image blocking) at the edges at the full 10mm. I realize anything on the end of that lens is not good at full wide. Gradual light fall-off I can deal with with PTLens.

I'll probably pop for a good (and unfortunately very expensive) 77mm filter, and then use a step-up ring for my 67mm and below glass.

And BTW, Thomas Nieman released PTLens 6.0 just this morning which now includes CA correction as well as a new vignetting algorithm. Worked wonders on my 10mm CA infected test shot. The profiles for Canon lenses also includes the profile for the 10-22 at about a half a dozen focal lengths.

My guess this was not a thin polarizer. I have the thin B+W 77mm cp. And it works fantastic.

are you related to Mike Fitzgerald???

If you dont understand why im asking this, i refer you to Andy ( he'll know )

It's a compliment!!!


BTW, Today I did a test shot of my new 10-22 Wide Angle Lens on my new Wide pool...... Im feeling so WIDE today!

This is all teh information I could find at the moment on the filter http://www.tiffen.com/filters.htm. It is the Circular, not Linear Polerizer.

David S_85 "I'll probably pop for a good (and unfortunately very expensive) 77mm filter," This one I got was expensive, $185, and is supposed to be high quality. I'm new to my DSLR and even newer to CP, so that is at least part of the quality issues of my shots.

Here are a couple more shots I took with the 10-22, all were taken with the CP on. There is very little Post Processing done to any of these. Sorry all these are at either 10mm or 22mm, I didn't take any in-between.






Thanks everyone for your comments. I'm still wet behind the ears and will benefit from any help I can get.

Nice pool! It pays to be WIDE sometimes eh?

I think PF is right...it does look like polarization effect changing across the wide angle rather than vignetting.

I have another question about these super wide lenses. Given the relatively large diameter front (77 mm), are these lenses more prone to ghosting/flare/stray light effects? I'm guessing the max aperture of f/3.5 here cuts some of these effects down....
