Hummers with the Bigma
Posted By: mmayer, 08-09-2009, 04:32 PM

My first pictures with the Sigma 50-500 (tripod mounted, 540 flash). This lens is really a "beast"!

Action frozen remarkably well.
Sharp and brilliant images.
Well done.

Thanks, yes it does require a fair amount of daylight, so I used my flash for these pictures. The camera/flash said it was set to 180s, but it's hard to believe that the wing action could be stopped at this slow speed. I really thought it took much higher speeds to stop the wings on a hummer.

Yes very sharp shots. Nice work.

What froze the wings was the flash not the shutter. The flash-duration creates the effective "shutter speed" for how fast the flash fires for any given scene. Depending on the power needed to illuminate the situation (darkness, distance to subject, lens FL etc.) The flash could fire from 1/1000 to over 1/20,000. Some 'tests' on the internet have shown flash durations of over 1/60,000. During the remaining time the actual shutter is open, it's getting very little ambient light, so the image is almost completely created by that millisecond the flash is lit during exposure. The action will be frozen better if the scene is darker. So if the flash is used as fill in normal daylight, there is a mix of the daylight image and the flash image. Both the shutter speed and flash duration will play a part in the final image.

Yeah... what Peter said... These are cool. Any way to change up the angle? Drop the feeder lower and or rise the camera POV? Also more perpendicular to their flight path.

How far away are you?

I've never seen a hummer without its wings flapping - you actually got one of it perched!

My tripod was only about 10 feet away on the driveway. I could have been about level with the feeder if the tripod was on the porch, but the little critters would never feed from that side of the feeder.
