What is crop factor? In general, people talk about focal lengths in relation to full-frame sensors, which are the same size as 35mm film. But digital cameras have sensors of various other sizes, and most are smaller than full-frame. A smaller sensor effectively crops the image produced by a lens, bringing the subject closer.

For bird photography, we generally recommend lenses that reach 600mm or more. That’s because birds often perch very high up in trees, but you need the same level of zoom when trying to safely get pictures of other wild animals.

If you’re planning to tour a city, the best thing to do is to pair a general-purpose lens, such as a 24–70mm zoom, with a 70–200mm lens for a little extra reach when needed.

Bird photography can be difficult. We spoke with photographers to find the best strategies and resources for making beautiful photos.

– 2:1 Magnification at the same physical size Laowa 100mm f/2.8 2:1 Ultra-Macro is the second 2:1 Macro lens that we have (The first one is the 60mm f/2.8). 100mm is one of the most common focal length for macro photography usage. All of the 100mm macro lenses in the market can only reproduce 1:1 magnification (life-size) image only. The extended 2x magnification means more details can be seen through the lens. Photographers can now take advantage of the wider magnification range to capture bugs at different sizes.

202473 — This article is merely a guideline for the purpose of each focal length, including some technical differences between the various offerings you see today.

For most court-based sports, which have a smaller play area, you can get away with a 200mm for shots of the far end of the court. But if the action moves closer, you’ll want something wider.

APS-C sensors, like the one used in our upgrade pick mirrorless camera, are in-between Four Thirds and full-frame with a crop factor of 1.5, so Fujifilm’s 16–80mm kit lens would be like a 24–120mm.

The wider lens will let you get street scenes and portraits, while the longer lens will let you capture architectural details or isolate subjects that you aren’t able to get very close to in a tourist setting.

What is focal length? Expressed in millimeters, focal length is what determines the perspective of your camera lens. The lower the focal length number, the wider of a view you see. The higher the number, the closer the subject appears.

Laowa 100mm f/2.8 2:1 Ultra Macro APO is not only a exceptionally macro lens. It can also focus to infinity and is a very decent telephoto portrait lens.

Sometimes wider is better—like when you’re trying to get a whole house into a picture or show off the details of a particularly stunning kitchen.

Followed by the success of the Laowa 60mm f/2.8 2:1 Macro, the 100mm f/2.8 2:1 Macro is the 2nd member of Laowa 2:1 macro line-up. It features an apochromatic (APO) characteristic that chromatic aberration at both ‘in-focus’ & ‘out-of-focus’ is both invisible. This new 100mm lens can cover full frame sensor size and focus from 2:1 magnification to infinity. The lens has a similar physical size to other 100mm Macro lenses in the market but its wider magnification range allows macro photographers to capture subjects at any sizes. This 100mm f/2.8 lens can also focus to infinity and serve as a portrait lens with exceptional optics quality.

If you’re sticking with a point-and-shoot, a superzoom that can reach 600mm should do. The wide-angle end of the zoom range doesn’t matter as much, though it could come in handy if you want to capture a murmuration of starlings at sunset or a herd of giraffes as they pass by.

– Apochromat APO design (invisible CA) The Laowa 100mm f/2.8 has a Apochromat (APO) design where the chromatic aberration (CA) at BOTH in-focus & out-of-focus area (Longitudinal CA) is controlled to the minimal. CA has long been one of the most annoying aberrations for macro photography and now you can forget about this and focus more on taking a great shot.

And beyond a certain point, even the impressive image stabilization systems in modern lenses and camera bodies can’t prevent blurry photos due to camera shake, which means you need to invest in a tripod to get sharp results.

Auto-racing, surfing, and field-based sports require the most reach, and for those you can likely get away with a lens that reaches out to either 300mm or 400mm.

All other mounts are manual and aperture is controlled by the aperture ring on the lens. For Canon RF users, please select Canon EF mount and use it with EF-EOS R adapter should you want to have automatic aperture function.

Serious basketball photographers switch between two camera bodies—one with a 16–35mm for close-up action, and one with a 70–200mm lens. The best strategy for sports is to move along the sidelines with the action, but this isn’t always possible.

What is zoom? For a zoom lens (that is, one that can change focal length by rotating the barrel), the difference between the minimum and maximum focal length is what determines its zoom ratio. This is usually expressed as 5x, 10x, 30x, and so on. If your lens is 24mm (or equivalent) on the wide end, a 5x zoom would mean it’s 120mm on the long end.

For example, the Four Thirds sensor used in our favorite mirrorless camera has a crop factor of 2. This means that you can multiply the focal length of lenses used on that camera by 2 to get the full-frame equivalent, so the Olympus camera’s 12–40mm zoom lens produces the same perspective as a 24–80mm zoom on a full-frame camera.

You need more zoom for this type of photography than most others. Whenever you take photos of animals in the wild, you should be respectful of their space and avoid impacting their habitat.

– Automatic Aperture (Canon EF) , Aperture Coupling (Nikon F) The Canon version of the Laowa 100mm Macro lens is equipped with an aperture control motor and CPU chip. The aperture can be controlled via the camera body (no aperture control ring on the lens body) and the aperture will close only during shutter release. Photographers no longer need to compose their shots in a dark viewfinder. A focus assistance indicator will also be shown in the camera. EXIF data can also be saved.

You usually don’t need as much zoom for sports as you do for wildlife, since you can safely get closer to the action, though there are exceptions.

If you have an APS-C camera and only want to carry one lens, you can use an 18–200mm zoom, which gives you a full-frame-equivalent range of 24–300mm.

Typically, for an interchangeable lens camera, the most cost-effective way to reach that far is to go with a zoom like a 100–400mm (and pair it with a 1.4x or 2x teleconverter) or a 150–600mm. These lenses are more costly than a lot of others but worth it when the alternative might be getting mauled by a mountain lion.

In this scenario, you should look for something like a 16–35mm lens, or even a 14–24mm. A lot of people also opt for single focal length (aka prime) lenses for very wide-angle photography. So, you might also consider a 14mm lens.

The short answer is yes. Lenses with longer focal lengths—especially zooms—are bigger, heavier, and often produce softer images than lenses with more modest focal lengths and zoom ranges. In order to keep lens size and weight down, apertures become narrower, meaning you have to use slower shutter speeds to get clear images.

If the purpose of your travel is to see wildlife, you should follow the advice above. Likewise, if you’re planning an adventurous vacation, you might want to consider an action camera.

Whether you’re shopping for a new camera or just want a new lens for a body you already own, you should be thinking about how much zoom (or, more accurately, which focal lengths) you need for the subjects you want to capture.

Here’s a quick overview of what focal length is, how it relates to zoom, and what focal lengths are best for shooting a few kinds of subjects including wildlife, sports, travel, and architecture.

– Similar size as 1:1 macro lens Despite the extended magnification range, the size of our Laowa 100mm is actually comparable to other macro lenses in the market.
