Photo of the Day – Unknown Red Flower

So many flowers, so little knowledge. I shot this flower growing in my backyard in the afternoon in September. I was experimenting with my super-telephoto lens. I don’t know what this flower is called, any idea?

The shot was taken with my Olympus E-520 using the 70-300mm super telephoto lens at 300mm. The E-520 is what’s called a Four-Thirds camera based on the sensor design and configuration. What that means, is the effective focal length is doubled because of the size of the sensor based on a 35mm full sensor size. So when I say that I shot this photo at 300mm, the effective focal length is 600mm.

I used a tripod with a remote trigger for this shot. Attempting to hand hold the camera with a super telephoto lens at this close of a distance, about 17 feet, would result in extreme blur. First, the camera is heavy with this lens and hard to hold steady, and second, a shutter speed of 1/50 sec is too slow for this focal length.

The super telephoto compresses the shot, where a wide angle does not. Take the same shot with a telephoto and a wide angle lens and you will see that the telephoto lens pushes things together and changes perspective. Even at an aperture of f/8, closer images are hard to bring completely into focus. I wanted focus on the flower here and got it, but if I wanted a sharper focus for the entire frame, I would have used a different lens.
