Here's am example of the Helicon software on a Mac
Picture is from my front door - it's raining outside, so this is the best you get
Here are two sets of four images. They were all taken with the 35/1.4 at f/7.1 - which is its sharpest aperture.
In each the upper left image is a "merged' version of the other three, which were taken with the focus set at about 3 feet, about 15 feet and infinity.
All of these are actual pixel crops. What is pretty darn exciting is how good the merged version looks on the house compared to the infinity focused version AND AT the same time how good it looks on the child's toy compared with the focus at 3 feet version. In each case the 'merged' version is just a hair softer than it's counterpart for a given focus distance, but it it is clearly a world better then (for example) the infinity focused image on the foreground at 2.5 feet.
Anyway, see what you think. I need to do some more tests and look more closely at a large print, but imagine being able to shoot at f/4 or 5.6 and having all the DOF one needs, without a tilt lens. Pretty cool.
