I’ve discussed the meaning of shooting envelope at length in the past. This is a practical, quantitative limit which effectively determines the conditions under which you can get an image of acceptable quality – usually, we apply it specifically to situations with one core constraint; either that the image must be made handheld, there are moving elements that have to be frozen, distance limits etc or something else. It applies indirectly to creative limits, too – if you want to make an image under certain creative (as opposed to physical) constraints, then one must seriously consider strengths and limitations of various possible bits of hardware. Put simply: I think of ‘creative envelope’ as the hardware’s ability to support the limits of my imagination. And this factor more than anything else has always been the underlying driver of purchasing decisions for me. I just realise I’ve never really explained it until today, undoubtedly leading to a lot of incorrect accusations of being a gear whore. What I intend to do today is explain the key factors that I consider for my own needs – yours may of course vary or change priority depending on what you prefer to shoot. I’ll also throw in a curveball: my best or most enabling purchase in each category to date.
