I have just tried an experiment with a Pentax K-5, 400-600 mirror lens; a T6 2x rear converter and a Metz AF58 fitted with a home made flash extender. The shot of a House Sparrow was taken at 1/180 sec; ISO 800 from an upstairs window. The result was far better than expected!! A little soft perhaps, but the 400-600 tends to be soft

If that was handheld, then that may be the reason for the softness at those extremes, worth trying again mounted on a tripod perhaps if poss

Because of the weight of the camera, lens and flashgun, I used a monopod for the shot, but thanks for the advice

Good stuff, it still might have not been enough support thou at your shutter speed of 1/180th sec even at 800 ISO

It is still very much work in progress, part of the experiment was to try out the diy flash extender, with the x2 rear converter added to provide a ridiculously long focal length of about 1800mm (with crop factor). A tripod would have helped except that there was limited space in the viewpoint, hence the monopod approach. I am hoping to try the set up in the field on Friday. Fingers crossed
