Hi David -
Thanks for the comment - it would be a feat to get one of these balanced on a snowflake, but they are about the same size.
You are right about the chromatic aberration - I had not noticed that. Interestingly, I can't see it after opening the raw file, but I used the 'shadow's tool in Photoshop to bring up the detail in the dark insect, and the seems to have made the CA pop out more. I'll check out Panotools since I'd be more or less guessing on how to adjust it in the PS raw converter....

Subject: Re: PESO - Snow Flea
Cool pic Mark! I've been trying to do some more high mag macro stuff recently but keep getting frustrated with camera shake or lighting or both. Anyway, you've done pretty well here! Love the patterns in the ice as well as the cool critter (pun, sadly, intended). Next - balance one on a snowflake (-:
One thing I noticed is that there appears to be some chromatic abberation present - check the red fringe on the right of the collembolan as opposed to the blue/green on the left. Try fiddling with the raw converter or using the panotools plugin for this purpose.
Cheers, David

My main goal was to test stuff out - the 67 55mm f4, Classic Pan 200 (the 120 film back after a production hiatus), and the Ricoh TLR I recently got off eBay. While tramping through the woods I noticed a bunch of snow fleas, so I set up with the *ist-D and the highest magnification setup I had on hand - a Kiron 105mm f2.8 macro and roughly 85mm of extension tubes.
These little critters are amazing - the run around in the snow in freezing temps. They are not fleas, but rather springtails (when they shoot off on their tails they move in a rather flea-like manner, so their name makes sense.) They are a little bigger than real fleas, i.e. averaging 1.5 mm in length. The tubes and the macro lens at closest focusing gave me decent magnification, though this image is cropped and the springtail is a bit small within it. It would of been nice to have gotten closer, but there are limits to what you can do in the field.

I was happy to see them as I had, till now, only read about them. Interestingly, they were only around one fallen tree, though I tramped by many a log on the way back to get them with the *ist-D.
As for the main mission - the 67 55 f4 is fabulous, the reissued Classic Pan is indeed faithful to the old (exact exposure / development times as used with the older version worked great) and the Ricoh TLR is a gas.
