Relationship
What Creates Different Ranges of Focus?

1. Aperture size. Large aperture openings like f 2 or f 2.8 will have among the shortest or shallowest of range of focus. A smaller portion of the photograph is in focus when using these larger apertures. Smaller openings, like f11, f16, and f22, result in a progressively bigger depth of field, as the opening is smaller (bigger numbers = smaller openings). More of the photograph is in focus.

2. Lens type. Wide angle lenses tend to have a greater range of focus than longer telephoto lenses. The same is true even with zoom lenses. When you’re zoomed to a wider angle, such as 35mm or smaller, you have a bigger depth of field than when the lens is zoomed to 100mm or higher.

3. Focal distance. This may actually be the most important setting for determining whether you have a very narrow or very wide range of focus. If the absolute focus point is set on a point less than a meter away from the camera, you will have a much shallower depth of field than if your focal point is 10 meters or more from the camera.

Consequently, although an f2.8 aperture setting where you focus on a subject less than a meter from the camera has a shallower range of focus than the same picture taken with a smaller aperture (f8, f11, f16, etc.), both images will have relatively shallow DoF precisely because the camera is focused very close. You’re likely to find that the DoF becomes narrower as you move into tighter quarters which prevent focusing on objects from a greater distance.

I have not ever worked with Aperture, Just PS and LR so I do not know the programs nuances

Sorry I do not Know Aperture so I cannot help

Just to help him and hopefully HE will read the manual :-D

Ditto I like it

First what program are you using to print? That will help use help you to get the best print

Here are pages from the manual to help, easy to do

First there is not one right histogram. Where the peak(s) are depends on the subject being photographed. The consensus is to expose to the right without touching the edge which gives you more latitude to play with in post processing

if it came with the tele adapter you will need to get a T adapter that fits your camera

All three are excellent I have bought from all. no problems with returns etc. Some Items on Amazon are sold by Adorama

They do fly but need a running start. here is a pano of a red-breasted merganser taking off

QA is important BUT by beta testing you may and do find problems which then can be corrected before the final release. Also problems are found after the final release that is why we get updates to our programs and firmware

Double ditto. It is the only way to go :D and old dogs can learn new tricks

I use their paper all the time most excellent

If you are handholding your combo I attach the Black Rapid to the lens foot
