I have only resonantly started using the same method. I use zone or wide for the focus area. I find the camera can follow very small subjects very fast that way.

I was experimenting two nights ago with manual settings on my flash to get a faster recycle time. At 1/8 power and a shutter speed of 1/250 sec. and f11, I can use burst mode at 8 frames per second and get good exposure on all shots up to over two meters. I haven't tested it on insects yet but am looking forward to it.

My 90 mm macro is best for that. The sigma 150 mm macro lens is using an adapter and the focus is not that good or fast. It might work with my FE 50 mm macro lens but I haven't tried it yet.

I like to limit my ISO to a range of 100 to 400 if possible.

I have previously used manual flash set at 1/64 power for photographing water drops. The (2) flashes were fired by an electronic trigger and the camera shutter speed was set to around 1 second. The short duration of the flash was effective at freezing motion and there was no problem with a secondary, blurred image due to the long shutter speed because I worked in a darkened room.

The reason I chose to use high speed flash with a high shutter speed for photographing hoverflies in flight instead of manual flash at my camera’s highest shutter synch speed was to avoid an unsharp ‘ghost’ image caused by the ambient light. Reading your post encouraged me to try the latter method, however.

I set my flash from high speed mode to 1/64 power, which automatically lowered my camera shutter speed to 1/300sec (max synch speed). I used f11 and set the camera to servo mode and high speed continuous burst mode. This set up enabled me to shoot a number of frames continuously without waiting for the flash to recharge. Trying to track and shoot several frames of a hoverfly in flight is a new technique to me and takes some getting used to. Also, I usually use one shot focusing mode which does not allow the shutter to fire until focus is achieved, whereas servo mode allows firing before focus is achieved. I did, however, get a few sequences of 2 or more sharp images, with the longest being 10 frames. The conditions were overcast and I did not get any noticeable blurring due to the ambient light and 1/300sec shutter speed. I tried the same technique on a sunny day and my images had blurring due the bright sunlight forming an image at 1/300 sec. The situation could probably be improved by lowering the ISO setting on the camera and increasing the duration of the flash but I want to freeze motion as much as possible. Going forward, I will probably restrict my use of manual flash with servo for hoverflies in flight to overcast days.

The following sets of images were taken in burst mode, servo focusing, 1/300 sec at f11 and flash on manual 1/64 power
