Hey, but wouldn’t decent Raw processors get rid of all the colour-fringing in cheap compound lenses?Has anyone here mounted their M4/3 camera to a microscope? I would like to do just that so that I can capture imagery of those tiny strange alien-like creatures that live in pond and sea water. It's a pity that decent quality microscopes are so expensive.
Hmmm....good point! I think there are other potential issues too with cheap objectives like average sharpness in the middle of the image and softness / distortion in the corners. And of course the really good microscope bodies would have an additional viewing port for adding a camera, leaving the other eye pieces free for viewing with human eyeballs. One of the things I enjoyed the most in science class back in high school in Adelaide was viewing those microscopic critters in pond water that looked more bizarre than any alien you'd see in a science fiction movie.Hey, but wouldn’t decent Raw processors get rid of all the colour-fringing in cheap compound lenses?![]()
I was essaying irony—I thought the rolling eyes pointed in that direction. Mmmm.Hmmm....good point!

Sample? I find Capture One to be very good at CA correction. I had a Zuiko 4/3 40–150 f/3.5–4.5 adapted to my Lumix G3—sharpness-wise it barked from around 90mm up, but had little CA (or was it simply well-corrected in C1?).… speaking of chromatic aberration, I had a really bad case of colour fringing while shooting a colony of fruit bats this year in Yeppoon, Queensland. I was shooting against the light using a slow telephoto lens (the Olympus 40 - 150mm f4 - 5.6) so that certainly didn't help. I had to brighten the images a bit in Adobe Lightroom but the resulting colour fringing was extremely severe - the worst Ive ever seen. I was able to reduce a bit of it in Lightroom but still, a lot of it remains. The CA is so extreme that you don't even need to zoom in to see it.
Oh I saw the irony! Yea I think I was wrong for putting all the unnecessary clutter in my post.I was essaying irony—I thought the rolling eyes pointed in that direction. Mmmm.
I haven't uploaded any samples yet - maybe I'll post some on Flickr. Though because of the bad colour fringing, I may only have them online temporarily. I'm not familiar with Capture One - I'll have to look into that software. Lightroom is usually pretty good at correcting most CA generally but it couldn't do much with the fruit bat photos.Sample?

I haven't tried with a microscope, and as you point out, good ones are expensive. I'm sure Olympus makes one with a m4/3 adapter, but being a leading supplier to the medical industry, I suppose the prices of their microscopes are prohibitive.Has anyone here mounted their M4/3 camera to a microscope?

I do have a Canon FD 50mm f3.5 macro lens that I occasionally use with my Panasonic M4/3 cameras. It came in handy for this pic of a black rock scorpion (Urodacus manicatus) under uv lighting.A cheapish and probably very functional solution is to buy an OM-adapter, one of the excellent OM macro lenses and an OM bellows or the very functional telescopic extension tube for OM. Even the cheap OM 50mm f/3.5 macro is a good lens, and the lenses designed for use with bellows or extension tubes are even better.
We got our national feast and fireworks a few days ago and I used the E-M5II along with the 40-150mm F2.8 pro zoom to catch it from my window. The contrast was very high, because the sky was completely cloudy and the night was very dark. I had to underexpose a lot in order to keep details in the highlights of the fireworks.
Here are a few :

Yay Hindley Street! That reminds me of a similar shot of the infamous Adelaide street that I took a number of years ago on 35mm slide film. I was using a Vivitar 75 - 300mm zoom to exploit the telephoto compression. Like your image, it made Hindley Street look rather hilly. I really like the colours in all three of your Hindley Street photos.Long shot
