Macro photography with extension tubes


Over the Christmas holidays my own present to myself arrived in the mail.
The extension tubes work by moving a lens away from the sensors inside the camera. The increased distance between the front lens and the sensors result in the camera's ability to only focus on near objects. 

As the name suggests, it's a tube without any lenses. You can stick your finger through it :P
Your camera clicks onto one end, and your lens on the other end.
It's so easy and fun to use, even Bunny wants to have a go!
It's similar to the eyes of many high short-sighted (myopic) people. They tend to have longer eyes than others with perfect vision where the front of their cornea is much further away from the retina. (Much further being >1mm.) 
The 3 extension tubes stuck together allowed me to capture fine iris detail. To capture this image I had to be ~5cm away from the eye.

It's 1/3 the price of the cheapest macro lens I could find.


So instead of food/wine blogging I’ve been running around in the garden taking macro photos of flowers and bugs. 
bottle brush bud things.

purple flower thing....
obviously I'm not a botanist!
these two ants were relaying information and taking turns gathering syrup from the bottle brush. It was quite tricky to capture them. They kept moving!



I also got sunburnt as a result from not re-applying my sunscreen after 4 hours.
I’m such a noob so I have so much more to learn.



this was also taken with the 3 extension tubes stacked one on top of the other.
Guess what it is?
Hint: its necessary for this blogger!
