RX100 VII How Small of An Aperture…

[DNBush]

…before diffraction kicks in?

Should I choose to purchase this camera for use in my travel photography I’m going to want the majority of my photos to have a very large depth of field and I’m curious what aperture would be appropriate yet not degrading to the image by being too small. I don’t have experience with cameras of this sensor size.

It’s best not to stop down beyond f/6.3, but up to f/8 can be used without serious degradation. With some macro images, it might be worth going to f/11, despite the risk of diffraction.

Diffraction kicks in at about f6.3. It becomes obvious at about f8.

shoot some quickies, you will find that you get near full focus depth at f5.6 with the 1" sensor, you need narrower when the sensor is larger

Diffraction occurs all the time. I assume you mean at what aperture does diffraction become noticeable.

It depends on one's tolerance for non-sharpness. It also depends on magnification of image. Combining these two variables a picture at full screen may be acceptable but viewing at 100% may not be.

Most of my pics are taken at widest aperture. Given the large dof with the relatively small sensor and the nature of my pics there is sufficient dof wide open.

Here is a quick, hand held, little care given series of pics. You decide.

That is true. I consider diffraction a problem when you can see its effects when viewing at 100%. That means as pixel density gets greater diffraction occurs at wider apertures.

Good series, thanks, Check the bottom left corner green into the grey stones, to see the amount of background focus achieved. I'll have to re-define 'near full focus depth' after seeing these
