Creating portraits using wide angle lenses can enhance perspective, but also distort proportions. If you capture the same portrait with a 24mm lens and a 50mm lens, the image from the 24mm will slightly distort your subject in the frame–especially around the edges.
For landscapes, a 24mm lens is an extremely popular choice for capturing those wide, epic scenes of city skylines or mountain ranges. 24mm allows you to play with your foreground and at the same time still get an epic view into the distance. So if mountain vistas or waterfalls are your things, 24mm could be for you.
For portrait photography, 50mm lenses are great for full-length and waist-level portraits, both on location and in the studio. This is thanks to the wide field of view compared to an 85mm or 135mm lens, and you don't need to be too far away from the model to achieve these crops.
24mm lenses has its place in street photography, especially in relation to incorporating distorted lines, multi-layered story-telling and capturing intimate portraits. It may be too wide depending on your personal preference, but it does have a specific visual appeal favored by many street photographers.
When it comes to photographing people, a 50mm lens emphasizes the subject, whereas a 24mm lens shows the environment. Image taken with a Canon 60D and a 50mm lens. That's why a 50mm lens is great for head and shoulders portraits, while a 24mm lens is great for photographing people in the context of their surroundings.
The wide-angle view of a 24mm lens is also advantageous for other photography pursuits, including architecture, wedding and event photography, street photography, and even group portraits. That versatility is just one of the reasons why you need a 24mm lens.
On a cropped sensor camera such as a Rebel XSi or EOS 50D, a 24mm lens gives you the same field of view as a 38.4mm lens would on a full frame camera. This is a useful "normal-wide" focal length.
The short answer is it depends on the style that you're going for. For example, a 20mm wide-angle lens may not be the first or go-to choice of most portrait photographers for headshots because they can be less than flattering to the subject. If you get too close, the nose and forehead will look bigger.
Not only is 24mm a great focal length for landscapes, but it's also a great focal length for other photography pursuits.
If you want to get crazy with focal length and shoot your portraits from a considerable distance, then you're going to want a lens that's bigger than 85mm. But like I said earlier, the general consensus is that focal lengths between 50 and 85mm are best for portrait photography.
Especially useful when shooting full-length and environmental portraits, a 24-70mm or 28-105mm lens that maintains the f/2.8 maximum aperture throughout the zoom range provides a good balance between low-light performance and zoom flexibility. In both cases, such lenses are designed for use on APS or full-frame DSLRs.
Is 35mm or 50mm better for portraits? Both are great portrait lenses, however, a 50mm will generally give you more depth of field (thus offering better subject separation), show less distortion, and still have a wide enough field of view to capture enough of the surrounding context.
For full frame sensors, a wide angle lens would be any lens with a focal length equal to or less than 35mm. Any lens between 35mm and 24mm is considered a wide angle camera lens. Anything between 24 mm and 18mm is considered an ultra wide angle lens.
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.
Because a prime lens is not only lighter and faster to use, but it offers sharper and better images. The quality and performance are light-years ahead of zoom lenses when it comes to portrait photography. The only downsides are prime lenses are more expensive, and you'll have to carry more of them.
Lens Choice for Group Photos
This gives you the ability to capture a larger group without the use of rows. You could also use a lens like the 24mm or the 24-70mm. The photo below (32 people) was used with a Canon 5D Mark III, 35mm lens, ISO 100 at f/10, and a shutter speed of 1/200th.
Mostly the Monochrom Typ 246. I also use the Leica M10-P. I use a vareity of Leica M lenses.
50mm lenses are fast lenses with a fast maximum aperture. The most basic 50mm lenses are typically F1. 8 - a very wide aperture. This means they are great for low-light photography (e.g. low-light portraiture or indoor shooting) as they allow more light into the camera's sensor.
If you love to travel and take pictures of sweeping landscapes or cityscapes then the 10-20mm lens might be what you're looking for. An ultra-wide-angle lens is also ideal for taking pictures of large groups of people since they allow you to stay fairly close to the group yet still get everybody into the shot.
If you barely do a tiny bit of astro-landscape photography, this might just mean adding a compact, affordable 20mm f/1.8 or 24mm f/1.8 prime to your bag. Or, if you do just as much astro-landscape work, or even MORE, then there's a good chance you will want at least one f/2.8 zoom, and maybe an f/1.4 prime.
With a compact design and weighing just 230g, the 10-20mm is the ideal second lens for travel, nature or landscape enthusiast, allowing you to take unique photographs that the camera's kit lens just can't do.
35mm Lens for Street Photography
The 35mm lens is probably the most common lens used by street photographers, and this is because it has a lot of advantages in this fast-moving genre. It is wide enough to capture multiple subjects in the frame easily or a subject and a background.
Adams and other large-format photographers often shot at ƒ/45 or ƒ/64, but large-format film images are much larger than 35mm or APS-C images.
Wide Angle / Ultra-Wide Angle Lens
Wide angle and ultra-wide angle lenses are the most popular lenses for landscape photography. Their focal lengths usually range from 14-35mm, though some can be as wide as 10 or 12mm.
