I like the Pentax K-3 with the 18-135mm lens for its versatility, zoom range, and focusing.  I don’t like the fact that it is large and heavy.  While I was checking how various cameras worked for photographing flowers, I checked their focusing and depth of field (DoF) at different apertures.  Since all of the flower pictures were at the end of the zoom range, I checked to see that it didn’t front or rear focus.  It doesn’t.  The easiest way to check is to photograph a ruler on close to a 45-degree slant.  You can see the results for the Pentax showing that it focused where I wanted at the six-inch mark and the amount of focus range in the following picture.

The Fujifilm X100F is OK when I want the lightest and smallest camera and shortest DoF by using a wider aperture.  The X-T2 with the 50mm F2 also works when I want to compromise with just a prime lens.  But, I’m still not satisfied and have some other options to try.
