    I've just bought a Sigma 105mm OS HSM after using a Raynox macro adapter for a while. I couldn't use the on camera flash with the Raynox because of the working distance/lens shadow. I was pleasantly surprised to find that it works with the Sigma. I've got it looking OK(ish) for some things by adjusting the flash compensation but it's still too harsh for some stuff, especially flowers and foliage. I've not used it for insects but I suspect it will be the same. How can I soften It? Or do I need to get an external flash for more options?

    Thanks Les, great shots - but when you say off camera, are you using a bracket to attach it or do you actually mean 'off camera' as in free standing somewhere? Sorry if that's a silly question. I don't have much experience using flash in general and especially for macro.

    External would be preferable along with a diffuser... however cut up a plastic milk bottle so that it forms a U shape and tape that on to diffuse the built in flash, effective, lightweight and cheap :)

    Cheers Phil I might give it a go.

    Christmas is coming though up so I might drop down hints to the o/h about a new flash ;)

    That is one hell of a setup, do you also use it handheld?

    I don't shoot macro on a tripod.
    When using that set up I change technique as it is pointless having all that lot together and trying to shoot at 1:1. The lens send up set to 1:1 focus which with all that gives about 3X magnification I then just move the camera to achieve focus.

    This would be shot with that set upand was probaly cropped

    This is the area that the Sigma 105 f2.8 plus three tubes and a Raynox on my Olympus E-M1 gets

    Not likely to get to the subject as the lens will creat a shadow still as the Sigma 105 plus a Raynox 250 would creat nearly 2X magnification and the subject will be very close.

    I’ve done the Pringle Tube diffuser and it’s quite a nice little task to do and have a play around with, it’s in the link posted above

    On a bracket or even hand held above or to the side of the subject, the wireless receiver on the Nissin Di 700 allows it to be used up to 100 feet from the trigger, mounted on the camera

    endless possibilities :)
