It’s sort of like micro as in microscopic but it is more telephoto or close-up of near objects rather than birds in a tree. Got it? It is a 105mm lens. Portrait? Well, not really. I can focus down to within an inch of my subject… get close… closer.
Great cat photo! I was surprised. The macro lens did a better job than…? Hummingbird? I happened to have the macro lens mounted on the camera as the bird flew toward the feeder. Serendipitous! Ditto, the bee, it was in my picture from the corner of the lens/my eye as I pressed the shutter. Spontaneous capture, definitely, unplanned. No error! It was skill! Ha ha. Sometimes I just close my eyes and press the shutter. Yes!
