I have been toying with the idea to use a 150-500mm Sigma as a macro by using an extension tube. Before buying a set I used a 2x-tele converter without the lens (tube only). I am amazed and puzzled by the results.
All the pictures were hand held. The long lens seem to me a option with insects that are camera shy. I tripod will of course made higher f-stops possible

1. at 500mm I could focus (manual) from about 1-meter to about three meters (this is more than the minimum focus distance with lens only).
1/320 f13 ISO-400 500(150-500)

2. At 150 mm however, I had at most 20cm focus distance I could therefore only use macro
1/320 f13 ISO-400 170(150-500)

3. 1/800 f7.1 300(150-500)

4. Crop No 3
