A friend of mine has several RC cars, so today he took them out for a spin while I photographed it.
This is just one out of almost 40 pictures. The rest can be seen
here. The last five or so are quite interesting :P The shutter speed of those images with the wheel were 1/6000s and still the wheel was blurry due to its motion.
The lens I used was my newly acquired
SMC Pentax DA* 60-250mm ED F4 [IF] SDM (unboxing video). Several of the images are cropped a lot to get the composition I wanted to present, so the lens is plenty sharp!
NOTE: The shutterspeed is 1/2500s. It wasn't in the list of available shutterspeeds in the form.
