Pic taken at the gardens of the Versailles palace in France, with the 10-17 fisheye. This short of shallow, see-through cloud covering further enhances the sense of depth and the vastness of the gardens.

I'm terrible at drawing, but I have this big box of colored pencils...time to put it to some use...hope you'll enjoy it.

Used remote controlled, diffused flash lighting to get the pitch black background. DFA 100mm Macro WR, close to 1:1 magnification with generous cropping.

Just been back from a short trip to Krakow, Poland. Used my newly bought DA 18-135 WR. Found it really versatile, sharpness is more than decent even at the widest focal length. (Even if it needs to be stopped down at least a bit to perform decently, wide open at 18mm sometimes shows very soft corners, i' d say unacceptably soft, i'm even thinking there's something wrong with my copy, like decentering or something, but strangely extreme softness only appears in some situations wide open...who knows...)

A few fun shots at different focal lengths...

Thanks ! Got another couple of interesting detail shots, this should be at 1:2 more or less. Tried going to higher magnification but at 3:1 you almost see the fibres in the paper and it doesn't look very good :D

Macro Help with magnification calculation
Posted By simon_199

Magnification is defined as the ratio of the linear size of the object on the sensor plane and its size on the image plane, which is none other than its real size. So if you have a ruler or caliper or something and just measure the size of whatever feature you want from the image above, for example the ball point, you have one of the needed quantities. If it is anything like the bic pen on my desk now the diameter should be approximately 1mm. Then you just measure the pixel size (horizontally for instance) of the ball point on your image and multiply by (sensor_size/horizontal resolution). If it's an APS-C sensor, for example, horizonal sensor size is 23.6mm. This gives you the size of your imaged object on the sensor plane. Then taking the ratio yields the magnification. Can't do the calculation right now as exif data are missing, besides not knowing if the attached picutre has been resized.

However, you don't need anything special to calculate the magnification, just to be able to measure the real size of the object you are photographing.
