A miniature monster
I do like the ripcurl. I'm very impressed that you're still being so inventive after all this time.
Thanks Chris, I don't mind admitting that it's becoming more of a struggle these days.

Large Red Damselfly
What a lovely picture, and I'm very impressed with its hunting ability. Its lunch looks bigger than the damsel itself!
Can you tell me what extension tubes you used, and why you needed them seeing as you used the zoom at 220mm.
it's the kenro auto extension tubes, and I used a 36mm tube and a 20mm tube in tandem for those shots. There are a few different reasons for this. Firstly, I use flash for most of my macro shots. It's usually not noticed since it's at a really low power, but that is how I get them so crisp. Because of that, I like to work at shutter speeds which are between the native flash sync speed and the focal length of the lens. For this shot then, 1/250s was my only option for reliable flash. The extension tubes brought the ambient light within the right range.
At longer focal lengths, extension tubes act more like teleconverters. The damselfly was about four feet away from me, which would have been quite small in the frame, since the focal length of the lens decreases to about 130mm at that combination of zoom and distance (since the focal length reduces for close focus). Using tubes, I can manually focus to infinity and I know that the focal length is what it claims to be, meaning higher magnification from a greater working distance.
It also meant I could avoid using the very extreme end of the zoom, because as we all know, that's not where a lens performs best.
Tubes also reduce your depth of field, and since this guy was close to the stuff behind him, they reduced the clutter.
Excellent. Thank you.
Good shots the Tamron 18-70 is what I need for my SonyA65,would save a lot of Lens changes out in the field.
