Ebooks Free Download | Canon EOS Rebel T2i/550D Digital Field Guide | The section on lenses seems to suggest that not a lot of thought has gone into writing a book specifically about the T2i - or even about Canon's APS-C cameras in general - rather than adapting an old 35mm (or full-frame digital) EOS treatise to the digital age. The discussion about the relationship between focal lengths and lens function (wide angle, normal, telephoto) speaks at length to the 35mm (full-frame) format before adding a closing remark - literally an afterthought - about how the T2i's 1.6x crop factor affects the categorization of lenses.
This full-frame bias appears throughout the book, consistently misrepresenting the nature of lenses that are only considered wide-angle on a full-frame camera. The survey of lenses fails to use photographs to effectively illustrate most of the points made in the text. A brief and rather pointless discussion of bokeh (the character of the out-of-focus portion of an image) ends by punting to Ken Rockwell's web site. I have a strong dislike for books that rely on web sites - especially sites not provided by the publisher - to present supplementary content. If a subject is worth mentioning, it should be worth writing about. When I buy a book, I expect it to be self-contained. I don't want to turn to my computer for the rest of text; I especially don't want to have to deal with web URLs that may not even exist several years hence.
The final three chapters of the book - a mere 65 pages - save this book from being a complete loss. Reasonable advice is given regarding exposure and composition and about shooting events, nature and portraits. While there's some discussion of how various Canon EOS features support different shooting styles, the overall treatment given by these final three chapters is barely more than a brief survey. Still, this portion of the book offers something that you can't get from the Canon manual.
