A bit more practice with macro video making:
A different lens combination used this time.
Canon 50D running Magic Lantern software, Canon 70-200mm USM lens fitted with Raynox DCR-150 macro close-up lens:
Also I remembered to check the ISO which had been at 800 but I reduced that to 200. As the wind was blowing a bit even small movements can put things out of focus at macro ranges. I used a retort stand and clamp to gently steady the Sunflower as much as I could:
The Japanese made Raynox conversion lenses have very good reviews. The DCR-150 works well with the 70-200mm lens where the zoom can be used to frame the subject and has a reasonable range of focus. Also I don't have to be very close, well not the few cm needed with the Nikon but 20cm+ for this combination. There is also a DCR 250 which would magnify even more but would need very steady subjects and I think would be hard to use 'in the field'. The Raynox is designed to use on the front of a telephoto lens, has a 43mm fitting but also comes with an adaptor which will fit 52-67mm threads by the use of two sprung clips built into it. The clips are grooved so they hold tight in the filter threads.
