The Stream and Pool image I posted last night was shot at ISO 1600. I would have never considered this high an ISO in the past but my new 5D3 handles it with aplomb and 17X22 prints should not be a problem. I did it because I could see that on the LCD screen, the ISO 100 pictures had very blurred out water totally devoid of the lovely reflections I was seeing. Even 800 didn't help but ISO 1600 and 1/8 of a second at f11 solved my problem. My intent was to use the ISO 100 images as a focus blend in Helicon Focus, then use one of the ISO 1600 images for just the water, but in the end simply blended the ISO 1600 images because they looked so good, then used one of those images for the pond water, and another for the further stream (moving water doesn't go well with focus blending).

The times and equipment are great.

This is interesting, and seems with mark III things are better when it comes to ISO 1600. With my 7D, reaching out to ISO 1000 is almost like a taboo for me now and with the weather here, even ISO 100 and a long exposure can be a hell of noise experience.

I wonder though if you can try to lower the ISO and use some speedlites at High-Speed mode and set a faster shutter speed. Well, I guess Syl Arena would have no problem here with his arsenal of speedlites wherever he goes!

I concur. In fact ISO 1600 is nothing nowadays. Now, just two years ago I did not even dare to go beyond ISO 800 with my Olympus e-P1. Now I am pleasantly surprised by the image quality even at ISO6400 when the conditions are right e.g. mostly bright light and the shadows are blurred by motion such as this It was taken with the Olympus OM-D e-m5. For this image I did not even have to do any noise reduction! The present state of camera technology reminds me of the era when audio cassette tape and tape recorder/player improved so much that they became hi-fi.
