Aperture control queries

    Good morning. I just enrolled into your course of photography. I must say, it’s a good set of sessions and i am enjoying learning that.

    I was on the stage of aperture setting, and I saw you achieving larger depth of field with f stop value to as low as 32. I can understand that you must be having a good set of lenses. With a lens of size 18-150, and a maximum f value of 6.3 (lowest aperture), how do I achieve a larger depth of field for travel or landscape photography?

    Dear Deepak, f6.3 is probably the lowest f value supported by the lens. The upper limit can be adjusted in the camera or lens depending on the model of the lens. You have just mentioned 18-150 lens, I am not sure if it is Canon/Nikon/Sony/Tamron/Sigma. etc. In aperture priority mode of the camera, you can change the aperture value to a good upper limit of at least f22 in almost all lenses.

    On a different note, an aperture of f8 or max f11 is good enough for majority of landscape images. Anything beyond that, you may lose the image quality.

      Thanks Sudhir. It’s a canon mirrorless. I think the aperture is lens specific and not camera specific. There is a mention of aperture limit f/6.3 on the lens itself. I really don’t know if you are right when you say, f/22 size can be achieved in almost all lenses. Even if f/11 can be achievable, it’s quite right for a larger depth of field as you suggest. I am planning to buy that camera- canon r10-with 18-150 kit lens.
