Try again

A couple of years ago, I bought some extension tubes 'cuz I'm too cheap to buy a macro lens. They were the cheapest you could get from eBay and had no automatic focus. 
In the end, I didn't have the patience, (or the eyesight), for purely manual focus so I sold them for what I paid for them. 
The itch to try again returned so I've bought some more, this time with autofocus. 
We shall see. (Or autofocus will). 

Ah well. Until tomorrow....
