I decided to try some manual focus with this lens. The first picture was taken handheld at 600mm, f/6.3, ISO100, 1ev and 1/400second. The second picture was taken handheld at 361mm, f/5.6, ISO100, -0.67ev and 1/640second. I used the viewfinder, not the LCD screen. The lens is obviously not designed for manual focus. The focus ring is tiny and not very 'sensitive' to fine gradations of focus. It's location on the lens barrel and its very narrow width make it extremely awkward to use handheld, not that many people are likely going to use it that way. Still, you can manually focus it handheld and get decent results as long as you are dealing with a fairly static subject and don't expect a high keeper rate. It worked much better than I expected.

I liked the late afternoon light shining through the central leaf.

How did you get a focal length of 960mm?

7D is a crop sensor camera, so the effective focal length of the 150-600mm Sigma at the long end is approximately 1.6x600 = 960mm

The effective field-of-view, is similar to 960mm (i.e. "frames like"). The focal length is still 600mm.
The worst picture ever is the one not taken: so shoot, shoot, shoot! Know your equipment first however to avoid as much as possible, bad photos. ;-)

Not being a gardener, I don't know the first flower in these 2 shots, but you did a masterful job in my opinion on composing and capturing their essence. Excellently focused too! Thanks for sharing.

The first shot is really amazing! The bokeh is beautiful and its very sharp. I like the motif as well. The flowers appear in a great light.

Photography is a lot like poker: You can learn the basics in a short amount of time but it takes a lifetime to perfect.
