Here are some examples

I am using a Sony H50 with a protective barrel on the end casing some vignetting at full wide angle. The model is Tamiya's 1/48th scale Pz IV and an Ott Lite for light.

This first shot shows the model on the black velvet background on my desk. The camera is set about 0.5m from the model. The camera is zoomed fully wide.


This photo is the same as above cropped to concentrate on the tank only.


The camera was moved closer to the model, about 5cm and the lens zoomed fully wide.


Same photo above but cropped. This photo is a little sharper than the long distance one above


Camera at the same 5cm but lowered to dramatize the feel of the photo


Same photo above cropped to act as a macro photo of the bow machine gun


Another photo taken from a distance of 0.5m but zoomed in


Same photo above cropped


same as above cropped to the bow machine gun


Down the gun barrel from 5cm


Same photo above cropped to the bow machine gun


Down the barrel from 0.5m


Same photo cropped. This photo looks very different from the closer photo. This shows how the different vanishing points change the feelof the photo.


Same photo again cropped to the bow machine gun. Notice the degradation in quality.


Fisheye lens added to my H50 from 5cm


Same photo cropped


Same photo cropped to the bow machine gun


Fisheye lens from 5cm


Same photo above cropped to the bow machine gun


So what have I learned from this little exercise? You really do need to get close to the model for a high quality macro photo. You can get decent overall shots from far away (over 0.3m), but not decent macro photos. This I didn't know until I did this.

Thank You, Nacho, for asking a good question and allowing me to learn something about my camera and taking macro photos form a distance.

My final suggestion to you, get the macro lens. If the extension tubes allow you to get closer to the model (within 10cm), then that might be the way to go. Just remember, you get what you pay for. My Sony cost less than US$400, but I am very happy with the results I am getting. I can allow the model to touch the lens and still keep most of it in focus.

I hope this helps.

aloha,
