Shd I buy a wide angle lens?

Ever wanted to ask a professional how they approach the landscape or wildlife or how they set up their camera for great photographs? What about asking what kind of gear the pro uses and why? Well here's your chance.

Shd I buy a wide angle lens?

I find that, on some of my landscape shots, the background is too far away and not well defined. Wd a wide angle lens be more appropriate? If so, wd a 18-24 lens be a good choice?

The attached picture was taken at nite with a tripod with a 55-200 lens @ f4.2, 1/250, iso 1600, 62mm focal length.

Complete opposite, you would need a telephoto lens, a telephoto lens it will compress the image, making the background look closer.

But a telephoto lens loses width in the shot. I have read that a wide angle lens is recommended (?) for landscape photography.

Dana,

The problem is your settings and Mitchell is correct about a telephoto lens compressing the background. When you take a night picture, you want to use a tripod, a lower ISO setting, a small aperture setting (f/5.6 to f/16 - diffraction could be a problem with a smaller setting) and a slow camera speed. Your image has a lot of noise because of the high ISO setting which was needed because of the shutter speed.

Here's a pic I took at night using a 35 f/1.4 lens on a 30D.
1/3s f/6.3 at 35.0mm iso400 (could have used a lower ISO setting)

This shot was taken from my driveway with a 17-55IS on a 30D.
1/4s f/2.8 at 55.0mm iso200 (I used f/2.8 since the only thing I wanted in sharp focus was the church steeple).

Here's one more just to show you a night shot with a wide angle lens (Canon 10-22).
1/30s f/4.0 at 10.0mm iso100 (this was shot without a tripod so I needed the f/4 setting)

S I guess I'm set with my 18-55 & 55-200 lenses. I just have to work on my settings when I'm composing a shot. Right?

Thanks guys.

I think you should be good with your current lenses for night photography. Just close the aperture a little, reduce the ISO settings and shutter speed and I think you'll be happy with the results.
I have the Canon 10-22 lens, but rarely use the ultra-wide settings. I use my 17-55IS a lot more than the 10-22 since I rarely need less than 17mm.
Be sure to post some images taken with the slower settings.

Photo 1 - 1/80, iso 100, f5.3, 145mm, wb cloudy

Photo 2 - levels adjustment & hi pass filter action

How do I get the results in #2 without pp?

Also I took some shots in complete darkness of a moonscape. My camera's, Nikon D40X, auto focus couldn't focus, so I tried using manual focus on a tripod with blurry results. #3 f4.2, 1/20, iso 200, 60mm, wb cloudy

Dana,

Try setting you aperture to f/8, f/11 or f/16. This will increase your open shutter time and should give you a little more color saturation, although you may still need to bump it up a little in post.
Some lenses simply capture color better than others and most of the ones that do are not cheap.
