G'day DJ

We've had some discussion over recent days regarding the use of Close Up Lens on your 70-300 zoom lens, and I offered to knock up some sample pix

At the moment I am in Hall's Gap, western Vic and a meander along the main street gave me these red flowers overhanging a front fence. To give an idea of size, each red flower is just about small enough to fit into a matchbox. Don't know what the flowers are called, but here they are

Camera is the Lumix FZ-35 with 35-420mm lens (dSLR eq of 24-275mm)
All images are full-frame, ex camera with no pp
All are shot at f11, and camera was tripod mounted
Close Up Lens is +2 dioptre with camera to subject distance = 1/2metre

1- image shot at dSLR equiv of 70mm


2- image shot at dSLR equiv of 135mm


3- image shot at dSLR equiv of 200mm


4- image shot at dSLR equiv of 275mm


5- this image shot using a +3 Close Up Lens, at dSLR equiv of 350mm


You will also easily see (in the above pix) how the background falls away once the main lens is over (about) 200mm, giving a great visual effect

Hope that this helps you a bit regarding the use of a simple close up lens on a versatile zoom lens - the 70-300 covers a good range.
