Do different lenses let in more light?

If you guessed the larger lens would make the image brighter, you would be correct. The larger lens has more area to collect light, which actually equates to an image more then twice the brightness at a ratio equal to πr² where r equals the radius of the lens.

Is there a big difference between f2 8 and f4?

The most obvious difference between an f/2.8 and an f/4 lens is in their “brightness”, i.e. in the maximum amount of light each lens allows to reach the sensor. An f/2.8 lens would usually be capable of giving a more shallow depth of field (and therefore a bigger background bokeh) than an f/4 lens.

What does f2 8 mean on a lens?

With the lenses you mention, the f2. 8 lens has an aperture which allows twice the light of the f4 lens and allows you to make an image in half the light or make an image at a lower ISO or with a shorter shutter speed in the same light.

Is 35mm wide enough for landscape?

A focal length equivalent to 28mm on a 35mm camera is often considered ideal for landscape photography because it covers a relatively wide angle of view without introducing obvious distortions.

What shutter speed lets in the most light?

With all other things being equal (aperture and ISO), a longer shutter speed will let more light into your camera for a brighter photo, while a shorter one will result in a darker photo. A shutter speed of 1/125 of a second, for example, will let in twice as much light as a shutter speed of 1/250 of a second.

Which f stop lets in more light?

The lower f-stops (also known as low apertures) let more light into the camera. Higher f-stops (also known as high apertures) let less light into the camera. This may seem confusing at first, but will make more sense as you practice taking photos with varying f-stops.

Is f4 too slow?

f/4 is not considered a fast lens. Since you shoot indoors, and low light, the 2.8 lens is a better choice for you. If you have top ISO performing DSLR, so f/4 could be good enough for you.
