Supplied as a basic kit lens with entry-level Canon DSLRs, the EF-S 18-55mm f/3.5-5.6 IS lens covers a focal length range equivalent to 28.2 to 88mm in 35mm format. This is a good choice of focal lengths for general photography and will suit subjects as diverse as scenery and portraiture.
Getting the best out of your kit lens
The 18mm is a moderate wide-angle lens that is great for landscapes, architecture, and environmental portraiture. The 55mm end makes for a short telephoto lens, ideal for compressing perspective when taking portraits or closing in on small details.
Since it has a good focal range to capture both wide-angle and zoomed photos, it's a great all-around lens. Depending on the focal length you use, you can capture a ton of great images with this lens. While using the wider angles like 18mm, this lens works great for: Landscape Photography.
Keep a good distance between the subject and whatever is in the background. Bring down the aperture size as low as possible. At 55mm, the maximum you'll be able to open up is f/5.6. Here you can see how big this hallway is and how far are the things from where the model was standing.
The closest focal length to the perspective of our eyes is the 50mm lens. However, photographers, in general, consider a portrait lens from 85mm up to 110mm. These lenses give you significant background blur and a shallow depth of field. They also allow you to position your subject far away comfortably.
Based upon the above, I am sure there are people out there that are concluding that their Canon 18-55mm f/3.5-5.6 kit lens will be fine for the wedding, after all it is an effective range of 29mm to 88mm on a full frame camera.
Zoomed out to 18mm, you get the equivalent focal length of 27mm if you were using a full-frame camera (also known as 35mm equivalent focal length). Zoomed in fully, it's the equivalent of 82mm on a full-frame camera.
Even bumping the zoom in a couple of millimeters from 16mm to 18mm can make a notable difference in image quality. All in all, 18mm is one of the most useful focal lengths for landscapes—right up there with 21mm below.
If you need a general purpose lens, and the Canon EF-S 18-55mm f/3.5-5.6 IS II Lens reaches the limits of your budget, it is a good choice. It is cheap, small and extremely light, has image stabilization and has a nice general purpose focal length range.
The 18-55mm lens is a great option for macro photography too. You may not be able to shoot tiny details like you would with a pro macro lens, but you can still definitely get great results.
A 18-55mm lens should really be only used at its widest angle, 18mm. This focal length is more than wide enough for most uses, including landscape photography. Unless you are always shooting landscapes, there really isn't any reason to consider something else for the job.
Full Frame (FX) – Weddings are notoriously unpredictable lighting environments. Shooting in dark, sometimes bizarrely-lit venues requires a full-frame camera for its ability to pull in every pixel of light from scene. There's also more data to work with when it comes time to edit. High ISO ability with low noise.
Aperture: f/4.0 for details and close-ups and the formal spouse-and-spouse photos to f/7.1 for a small group shot of the wedding party to f/8.0 for the church and large groups. ISO Setting: 100 for a bright or sunny setting to 800 in a dimly lit church; at a nighttime reception, you may go to 1000 or higher.
A typical setting for the portraits would be: 1/60 second shutter speed, F5. 6 (or higher you need more light), and ISO 400. Keep in mind you are setting the exposure for the background so one thing we always think about is how much of the background do we really want to see?
the 18-55 lens might allow for more background in your photo, if that's what is needed. the 55-250 might allow for a more blurred background that people tend to like. in either case, position and location will help with the kind of photo you're looking for. Re: Which lens is better for portrait- 18-55mm or 55-250mm?
Lenses with focal lengths of at least 50mm are more suitable for headshots and portraits because they are more flattering to human subjects. Popular headshot focal lengths are 85mm, 105mm, or 135mm. A telephoto zoom with a range of 70-20mm is also a favorite with headshot photographers.
Many photographers say the best focal length for street photography is 50mm, and 50mm lenses do offer a great perspective (plus, this field of view has been popularized by many famous street photographers). Those who like the 50mm focal length but use crop sensors should go for a 35mm lens.
The background is of fundamental importance in the composition of the image emphasizing the subject, improving the photography, or if not adequate, it may cause irreparable damage to the image, making it chaotic.
The background is what sets the stage for your entire composition. An effective background will add to the story, providing valuable information about your setting, and helping to dramatically enhance your photo. You should focus on the background as much as you do the subject.
