    You've really got this down Barrie... such mental focus required to nurture these images into their final form. I am in awe, man.

    Thanks for your comments gentlemen, much appreciated. Half the battle is finding the little guys in the first place, though moths are easier as I run a moth trap from time to time. The Sigma lens has become my macro of choice for mobile subjects with it's retained ability to automatically stop down.

    With these Sigma 4/3 lenses, does the AF still work or is it manual only?

    Ever think of just training them, and then perhaps set up a traveling circus?

    manual focus only on the 105mm lens Andy, but that is no drawback for close up work, in my experience the auto focus is not precise enough.

    Sadly they always seem to want to fly away, or die on you and then you have to start again :smile:. I do sometimes raise caterpillars but they can be rather demanding, feeding and cleaning etc.

    Ahhhh... the zeitgeist moment... it just hit me. You raise caterpillars to feed the birds you take photos of eating moths that you want to get close to.

    Vewwwy cwehveh.

    Just picked this lens up, replaced my 60mm as I wanted more working distance. Its nice to have a "legacy lens" that will still AF if needed (and faster than I thought), auto aperture works so brighter viewfinder, and no need to remember to set IS focal length.
    Only downsides so far:
    • two steps involved in switching to manual focus
    • the AF is pretty noisy (actually I wonder if there is something worn a bit in my copy)
    • the aperture is also a little loud. Using TTL flash you can here the aperture stop down twice quite distinctively once for the pre-flash and once for the shot, total sound is as loud as the shutter, not a major negative for its use but surprised me at first. I am not sure if other lenses act the same way or if they just stay stopped down in-between preflash and flash but this is the first one I really noticed.
    • Lastly its not great with veiling flare, can get a bit hazy if you don't much the light source.

    Other than those minor niggles its a fabulous lens....VERY SHARP, manual focus has a nice feel, and I like the build, not too heavy but still feels likes its decent quality.

    Here's a couple samples so far:
