Aperture

Ok so I am still learning and plan on going to school in the Spring. I have been reading a lot about what aperture is but I am hoping for some clarification. Is aperture limited by camera, lens, or both?

Re: Aperture

Aperture is normally associated with the lens only as it is built into the lens its limits set by lens type and design.
As it is only one part of the exposure equation along with shutter speed ISO etc you may find the following simulators helpful in giving you a better understanding

Re: Aperture

Thank you both! Boneappetit I had heard of the program but I was refering to what Tony is talking about.

@Tony That is what I thought but I wasn't 100% since I have been looking at cameras and it mentioning aperture in the specs though now that I think about it those were probably bundled with a lens :P. So if I understand right if I had a low end entry level camera it would not restrict aperture of any lens I might have in the future. Thanks a ton! Also ty for the links going to check them out right away.

Re: Aperture

SierraBella lens manufacturers normall quote aperture as part of their specs. it is actually a physical part of the lens (a leaf mechanism that opens and closes to let in more or less light) and the usuall quote is for the maximum aperture. For instance a prime lens may be quoted as having an aperture of f/1.4 or f2.8 whereas a zoom lens may be quoted as having f/3.5/f/5.6 - more expensive zooms can have a fixed max aperture.

You are correct an entry level camera will not restrict lens aperture in any way.

Re: Aperture

Thanks Tony very helpful exactly what I was hoping too lol. I do think I understand the effect on light now also. I won't say I understand completely since I have yet to (other than the simulators) experiment for myself but definitely much more than before. I can't wait until I have my camera Spring can't come soon enough!
