New lens

My new lens is capable of an Fstop as low as 1.8. My normal lens can only go as low as about 3.8. A low Fstop indicates a LARGE aperture-- in other words, a large opening. With a large opening light comes in large quantity so the shutter must close quickly or the shot would be overexposed--too light.  My new lens is super fast. This also makes it great for low light situations like indoor sports or birthday party with candles lit on the cake.  The wide aperture allows a very shallow "Depth of Field". Basically that means that the focus is shallow. A very sharp focus on the subject and everything else blurred.  The shallow Depth of Field is the main reason I have wanted the lens for a couple of years.  I have achieved some degree of shallow DOF in the past by using my telephoto lens from further back and zooming in to the subject. But, it isn't as good as the capability of the new lens. Here are a couple of examples-- basically shots I just couldn't wait to take because I wanted to try the new lens. The one of the blossom wasn't taken at a very nice time of day for attractive light, and the one of my son was taken moments after I bought the lens! He was waiting for me, leaning against a building right there on J Street. I had him "wait right there" and yanked the new lens out of the box. He wasn't too happy about posing :) But, I just love the what the lens accomplishes in the shade.
