Join Ben Long as he teaches you about the importance of lens speed. He profiles three different types of lenses—fixed aperture prime lens, fixed aperture zoom lens, and variable aperture zoom lens.
- When it comes photography, the word speed…can be very confusing because…it refers to so many different things.…There's shutter speed, the ISO is considered…a measure of the speed of your image sensor.…You might refer to the speed of…your camera's burst shooting mode.…As mentioned earlier, your lens also has a speed.…When we refer to the speed of a lens…we're talking about the widest aperture that it can open to.…I've got three lenses here.…They don't all open the same amount.…I can't get them all as wide as each other.…All lenses work this way and you can figure out how wide…a lens will go by looking for some certain markings.…
This is a 24-70 millimeter zoom lens.…If I look on the front ring here,…I see 24-70 millimeters, so that tells me…the focal length range of the lens.…Right next to it it says...…There's a ratio listed, it says 1:2.8.…2.8 is the widest aperture that this lens can be opened to.…That's actually a very nice fast lens.…2.8 is going to give me some pretty shallow depth of field,…it's going to let me work in low light,…
