Need to have an idea of how can i choose a lesnse for my Camera Canon EOS 450D. What does the number on the lenses means? What is the differnence between the names of the lenses ?!?!
Dear Friends;
I bought an SLR Camera from Canon. The module of the Camera is EOS 450D. Iam unhappy with the default Lense and i would like to buy another one. Now when i started to search in the Internet, i found different types of lenses for 450D and that is normal but I need to know How can I choose a lense for my self ?!?!? I dont understand the numbers for the models.
For example:
1) Canon 55 - 200mm f/4.5 - 5.6 USM II Lense.
2) Canon 75 - 300mm f/40 - 5.6 III Autofocus Lense.
Another thing that there is different names for the lenses, and guess this will be for the different ways they are working like:
1) Fish eye.
2) Wide Angel.
3) Telephoto.
What does the traveler will need to buy from these lenses or any other lenses?
Can Anyone Help me please.

I would personally recommend one lens with a wide range like Canon's new 18-200mm. One wide range lens means you can carry less lenses. In my case I travel with (this is Nikon by the way) 14-24mm, 24-70mm and 70-200mm lenses. If you have one 18-200mm lens you cover almost all of those in one lens.

Reply to this well its depends on the camera you purchase it. It will be displayed on the box how much zoom can we done so as to get picture unchanged. It will be suggests that you should take the higher megapixel camera so as to get the picture clearly visible even if we make it to bigger than its normal size.

Reply to this Hi Ray,
I bought my EOS 20D, which isn't much different from the 450D, about two years ago.
Here's what I found:
1. Zoom lenses are the best ones to have. They don't take quite as good shots as prime lenses (fixed zoom) do, but they are far more versatile.
2. Image stabilization is well worth the extra few bucks. On canon lenses, this is indicated as "IS"
3. I found having two zoom lenses with Image stabilization and overlapping zoom was perfect.
The two I have are the EF-S 17-85mm IS USM 4.0-5.6F and the EF 70-300mm 4.5-5.6F DO IS USM. I'm pretty happy with both lenses, although you can go down a notch in the 70-300mm to your second lense above without losing much quality.
A few notes:
17mm is a reasonably wide angle lense. This should be enough for 99% of the shots you want to take. It probably wouldn't make much sense to purchase a super wide angle (Fish-eye) lense (usually 10-22m).
Generally, a standard lense is 35mm, so anything less than this is considered wide angle, and anything considerably above this is considered telephoto.
For most of your shots, 300mm will be plenty. That's pretty close to the limit for hand held daylight shots (and way over for low light).
The F number refers to the maximum apature. The higher the number, the less the effective apature opening. That means a slower lens (which comes into play for sports photography) and less depth of field. You can't adjust this number down, but you can always increase it to about 32, which helps get the background and foreground in focus.
Nearly any lense you will buy will be autofocus.
I hope this helps.
Reply to this Well, wide angle are lensused for arhitecture and large view of peisages. have large angle of view. Telephoto are lens for loong distance photography bat are not have large angle to images catch. I used one EF-S 17-85mm IS USM f/4.0-5.6 ; 70-200mm f/2.8 USM and 10-22mm f/3.5-4.5 USM, al lenses for CANON 400 D. On aproach moment a make one upgrade to another level camera: CANON 5D Mark-II-
On my opinion for good images on all time, are best one lens with a large aperture ( f/2.8 ) used on low light.
