I'm considering getting my first DSLR (a refurbished Canon Digital Rebel) and wanted to ask a few questions. Okay, I've never used an SLR camera in my life. My current camera is a Canon A530 compact camera with very limited manual controls. One of the things I noticed is that it only allows me a choice of two aperture settings (say 2.6 and 5.6) for any particular scene. I just finished reading Bryan Peterson's book Understanding Exposure and it sounds to me like one of the advantages to having an SLR camera would be the freedom to use a wider range of aperture settings. Am I correct in this? Second, the camera I'm looking at is not listed as coming with a manual. Is there any way to get a hold of a camera's instruction manual when it doesn't come with one? Even with my current camera I had to read the manual to figure out how to set some of these things up (I had no idea how to read the light meter until a few weeks ago!) so I'm assuming I would probably have questions about how to operate the Rebel too. If anyone can help answer my questions, I would definitely appreciate it.
