I was looking for some bugs to try some macro photography with that reverse lens apater, but I failed on this task.
Anyway, I didn't give up and decided to try take some flower shots, here are the results :)
It's pretty hard to focus while shooting with reverse lens, every little movement can ruin the whole picture. Even thought it's a little out of focus, I like the results.
