Indeed Rob,I used the 150mm Bugma.The picture is the result of a bit playing around on a sunny Saturdaymorning while the sun shines over my office.
During a phone call I'm playing around whit a small hourglass. Holding it against the sun rays,it gives a nice effect.
After the call i took my camera and Bugma,and start playing.In one hand the hour glass,in the other my camera.Constantly moving around to find the best rays of sun.
That blurry thing under is my thumb.
