Macro and Back Focus This is the final book in a series which examines The Lens and Its Image. Macro and back focus are areas that are not as well known as the topics in the previous books, and so it is good to find out exactly what these terms mean. You should be aware that both macro, and especially back focus, require very precise adjustment if focus problems are to be avoided.
By studying this book you will learn how to use the macro controls on lenses correctly. You will also be shown how to set the back focus on your camera accurately so that you do not run the risk of all your focusing arrangements being out. You are taken through the back focus procedure step by step via a movie clip and after watching it a few times you should feel confident enough to set the back focus on any camera you are using.
If you are thinking of buying a secondhand zoom lens, you will find the chapter on how to recognise problems like axial shift and creep really helpful.
Lastly, of course, there are the lists on things you should be able to do and the questions you should be able to answer. In addition there is a multiple choice Quiz which covers all 5 books in the series.
The book contains approximately 21 minutes of movie clips.
