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.

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:

Here's a few shots with my used, but recently acquired, Sigma 105 f2.8 EX DG macro in 4/3rds mount. SOOC JPGs. Took it out to Kapiolani Community College cactus and succulent garden yesterday morning on a somewhat rainy day with mixed cloudy skies. Mixed AF and MF on EM1 and MMF-3.

ISO 800, 1/800. f5.6. The funny thing is that I didn't even notice the ant until I looked at it on my computer. Was trying really hard to get the flower in focus. Should have used f8 or smaller to get them all in focus. Shallow DOF.

With my Sigma 105 f2.8 EX DG macro in 4/3rds mount. At the Pacific Aviation Museum this morning. Flag flying from the refurbished Ford Island control tower, which was officially rededicated during the 75th anniversary of the Pearl Harbor attack. They eventually plan to reopen the top of the tower to tours later on when refurbishment is completed.

Hauoli Makahiki Hou (Happy New Year) everyone! Best wishes for the coming year.

EM1: ISO 200, 1/1250, f5.6. SOOC JPG.

I was just looking at the above photo again, and wondered how they painted underneath the platform. To get an idea of how hairy that must have been, take a look at this showing the whole tower. Yikes! They must have used a snorkel truck or something. (Shot at 15mm with the 12-40 Pro.)

Yes, that's the famous (or infamous) X-band radar platform in the background. :)

Thought I'd try to add some to this thread. Sigma 105 f2.8 Macro in 4/3rds mount on my EM1.

This was the only dragonfly who cooperated by sitting still for a while. Bit of an overcast day. Contrast perked up a little.
