It's usually not a big deal unless you have long objects which extend deep into the background. Then the difference becomes quite noticable. Also, it's best to model with the same lens as will be used for your render, especially if you are designing from a perspective image/sketch or you're planning to composite into an existing image.

Thanks Jonah.
You are saying that, if you plan ahead visually, you can take all the fun out of trying to get things to work properly in the Rendering apps!
