interested in getting new lens, need advise

[iCeQubeTomato]

Hi Im new this forum. I own a Canon 50D and a EFS 18-200 lens. I have been shooting with this lens, mostly landscapes and wedding photography. Recently the Canon 10-22 have caught my attention and I would like to know:

1) should I still get this lens since I own the 18-200?

2) if so, what can the 10-22 lens do that the 18-200 cannot?

3) does the 10-22's "10" means i can fit more stuff into my frame than the 18-200's "18"?

Looking forward to hear from anyone soon!

Cheers =)

Hi and welcome to the forum.

Simple answer is yes. Get a 10-2x (more on the x later)

The 10-2x will enable you to get a LOT more in the frame. All the landscape togs (myself included) swear by them.
Another user, a petrolhead, uses one on a jig to get all the car in on moving car shots.

Now, I say 10-2x as a very worthy other choice lens is the Sigma 10-20mm. This one is about £350 (not the newer £500 version Sigma just brought out) and so is a considerable saving over the Canon 10-22mm.
I personally went for the Canon, as most comparison reviews gave the Canon better marks for image quality (slightly) but they ALWAYS gave the Sigma the recommended award due to being a lot cheaper.

You won't go wrong with either.

Excellent!


Thank you so much

An UWA lens is great for close-up stuff as well. You can get some really wacky angles by jamming the lens in real close. I love my Sigma 10-20. Easily my favourite lens and my most used. Can't comment on the Canon 10-22 as I've never used one but track down a sharp Sigma and you won't go wrong.

I bought the canon lens today. There is a problem, when I put my polarizer filter on, the camera captures shadows around the corner of the frame at 10mm. The only way to avoid that is to take the filter off the lens. Is there something wrong with the filter or this lens is too ultra wide?

For ultra wides you will need a slim line polariser.

This is the one I use.

First, do you also have a UV filter on the lens? Ie, are you stacking two filters together? If so, you'll need to remove one. The basic issue is that the lens does have a very wide field of view at the 10mm end - wide enough to see the rim of the filter. It may be the case that some filters still have a rim that's deep enough to be seen at the wide end of the zoom range. When I got a UV filter for my 10-22, I specifically went for one with a low profile. I don't use a polariser with it, but I did notice that there are special low profile versions of those as well.

In general, a polariser has a deeper rim than other filters because it's actually two layers of filter and two rims - polarisers work by rotating two filters relative to each other. The rear rim screws into the front of the lens and holds one layer of filter, and the front rim rotates while holding the other layer of filter. The extra rim and layer of filter mean that they tend to be a bit deeper than normal single layer filters. For most lenses, this is fine, but can result in vignetting with a ultra-wide angle.
