We often observe those who are new to photography, and many who are not so new to it, ask... upon seeing a stunning image that was created, "what camera (or lens) did you use for that?" Often assuming that by using a particular camera or lens, such a stunning image was made possible. While the characteristics of the lens, in particular, can contribute much to the particular "look" of an image, the camera itself usually, MUCH less so. In fact for most images, the camera itself (perhaps with a few exceptions) is almost meaningless. For portraits, in particular, many think that to make a great portrait, a particular focal length or specification of lens in key to this. Nothing could be farther from the truth. Great portraits are the result of eliciting a great, natural looking expression from the subject. Beyond that, the photographer's choice of setting, background, where to place the subject, where to place the camera, time of day (if outdoors) how to light the image (or how to use/modify available light), the subject's position/pose, what the subject is wearing, what the subject is doing, and foremost, again... the subject's expression have FAR more to do with the success of the image than what lens was used, MUCH less what camera was used. For the beginning or intermediate portraitist... if you give as much (better, MUCH more) time and attention to all the factors I mentioned above as you might give to deciding what lens to buy for portraits, you will be miles ahead. A skilled portraitist can create an incredible, stunning portrait with almost any lens you might think of. It is all in how the portrait is conceived and carried out. Granted, the lens is part of the equation, in terms of creating a particular "look", but there are a great many, very different "looks" that can make a stunning portrait, aided by a wide variety of focal lengths, apertures, and lens types. We all love gear and enjoy what it can do, but what it really comes down to, folks, is NOT gear... it's what YOU do! The most incredible images that one can observe have very little to do with the gear. It's almost entirely about what the photographer did to make it all come together. Remember this when someone who is impressed with a particular image asks "What camera do you use?" Or "What lens do you use?" At a dinner party, following an incredible dish that was served, a guest turns to the host and asks... "what an amazing dish that was, incredibly delicious... what kind of stove do you use???"
