Macro? Close-up?I joined this group because I need the "pressure" to improve my picture-taking eye.
I took these pictures, not so much as "art" as "technical research" to get an idea of what my camera will do in the line of macro/close-up photography. I really should take pictures of a good scale but... this is what I did....
First - although I took it last is this full fr
At 72 pixels per inch the image would be 53.78 inches wide; this would allow me to crop to just around the dime and re-size to 8 inches. While that would appear to be macro, it does not meet the definition of life size or larger on the film or sensor (which is 23.6mm wide while the dime is 17.89mm in diameter.
Now that we have seen my target here's what I did. I took my first picture with the 300mm lens at closest focus with +4, +2 and +1 close-up lenses all attached. I know Kodak says only use one or two stacked close-ups. I set the camera to manual focus and racked in and out using the center column on the tripod. The following image is full fr
Then I took off the +1 and tried again. I got a little more of E Pluribus Unum this time which I measured as 10.4mm giving a 2.6:1 ratio or still bigger than life size on the sensor and therefore macro.
Finally I took one with only the +4 and got still more of the coin on the sensor; I measured what I got at15.3mm giving 1.5:1 macro.
I should write this down somewhere in my technical stuff as well as do the work for the other combinations of close-up lenses. I have a +10 lens from my film days but my Sony APS-C lenses have so little room between glass and filter thread that I can't screw it in. LOL
Post updated 3-17-2012 to show the exaggerated claim to be a macro lens.
Post updated 4-4-2012: Last night I reread the instructions for both my lenses and they both say maximum magnification is 1/4. Well now I know I don't have to put the long zoom on the camera for close-ups or macro.
