Macro testing using the Pentax 645D a 67 100mm macro and extension tubes

I thought I would test just how close I could focus when using the 100mm macro lens from my Pentax 67 camera on the 645D. I first took some photographs of a steel ruler (as shown above) then moved on to the lego man (naval officer?).

First 645D body, 67 to 645 adapter, and 100mm macro lens.

Then add the 1:1 adapter to the front of the lens (This comes with the 100mm macro lens)

And then add extension tubes 1+2+3

It should be noted that these are the full size images and not crops. If you use the macro lens with the 1:1 adapter, and extension tubes you can focus so that an object 19mm in width will fill the frame. Of course you could then crop the image further. This is a crop at 100% from the above shot.

This leads me to ask the assorted creepy crawlies on Okinawa…

“Are you ready for your close-up?”
