What are the practical advantages of fast lenses when shooting landscapes?

When used at the same aperture and focal length, a faster lens will have less vignetting than a slower lens. For example if you choose to shoot at 35mm f/4.0, then a 24-70mm f/4.0 lens will have the ...

What are the practical advantages of fast lenses when shooting landscapes?

A faster lens (= low F-stop) allows easier manual focus and better auto-focus, given the camera has AF sensors which can exploit faster lenses. For landscape however, there is usually enough time that ...

What are the practical advantages of fast lenses when shooting landscapes?

Consider low light conditions. If you can use a low F-stop, you can use a lower ISO. You'll then have less noise and higher dynamic range. Even with a tripod, you'll have more options if you only need ...

What are the practical advantages of fast lenses when shooting landscapes?

Faster lenses give you almost always better image quality than slower lenses at the same f-stop. This is true for vignetting, resolution and contrast, distortion and color. A faster lens also gives ...

Best camera for long-range action shooting

I don’t have a dedicated camera. Just using an iPad, not good enough though. Distant shots are grainy, and fast-paced mages get blurred. You have arrived at what you think is a solution to your ...

Which should I buy as a starting prime lens, Canon 35mm f2 or Canon 50mm f1.4?

Your camera has a 1.6x crop factor. On APS-C, 50mm gives you the field of view of a classic portrait lens on full frame (80mm). While 35mm will give you the FOV of a "normal" lens (56mm). If you want ...

Are fast lenses needed for astro photography?

Depends what sort of AP you're talking about. And whether you're using a standard photo tripod or a proper astronomical tracking mount. For a standard tripod, you're limited in exposure by star ...

Why is there an air gap between lenses and digital sensors, as opposed to continuous glass-like higher refractive index?

Since lenses work based on the difference of index of refraction across the interface as well as the curvature of the lens surface (the more the difference in I.R., the more the light rays are bent) ...

The sensor in the Panasonic Lumix DMC-LX15 is 2.74X larger in area than the sensor in the Panasonic Lumix DMC-LX7. That is a considerable advantage. If two sensors use the exact same technology, a ...

Faster lenses aren't necessarily inherently better for landscape photography, because the implication with 'landscape' is a stopped-down shot, preferably on a tripod. Are you stopping down now? If not,...

For sports photography, should I use image stabilization or a faster lens?

I'd say it depends on if you are shooting indoors or outdoors. IF it's indoors i will keep the f2.8 lens. So the camera will happily focus faster with lower Isos and so you'll get cleaner images. If ...
