Why limit it to hyperfocus? My idea on the Dear Pentax thread (slightly modified) is this: Why don't digital cameras have a fully digitalized way of determining depth of field? I'm talking about the camera both figuring out DOF for you digitally, and providing a simple but detailed readout that allows you to "see" DOF and decide how much DOF--all digitally.
Is something like the following scenario possible and feasible? Your autofocus lens sends info about aperture and distance-to-focused-subject (as well as focal length) to the camera. The camera's processor calculates a depth of field range, which shows in the viewfinder.
This effectively moves the depth-of-field scale off of the lens body into the viewfinder (and LCD) digital info. Furthermore, the DOF scale in the viewfinder would be colored, with red at either end, yellow towards the middle, and green in the "middle", corresponding to degrees of sharpness within the DOF. The numbers on the DOF scale would indicate the range in focus (one could set it for inches, mm, cm, m, or ft), and they would change as aperture changed or focused distance changed or focal length changed. So at any focus point with any AF lens at any aperture you could immediately tell DOF. A further possibility would be for the viewfinder (and LCD) to be able constantly to project onto the image a minimal scale corresponding to DOF.
No more looking at charts. No more looking at lens bodies. No more having to see and make judgments about darkened images in a viewfinder.
I'm not aware of any camera manufacturer that has done this. So, if it could be done, and done within the size and price of a typical digital camera, it would be a scoop for that manufacturer. And I submit that it would be highly prized.
Sounds lika an excellent idea. But why stop there? I'm sure it is more information that is handy to have in the VF. Isn't it possible to project a transparent text/image on the focusing screen like the fighter pilots have? Maybe accessable from a set of quick buttons.
To get more "real", I want:
- Better AF-C
- Increased DR. More wanted than less noise at high ISO imo. But I dont think we will se the same leap for the sensor that we saw K10 -> K20.
- Slightly smaller body compared to the K20 (I have small hands and so has the japaneese design team I hope
)
- A bigger VF. Maybe 100% and 1.05 magnification. This is to compete with the FF cameras other companies are offering and give us a similar hole to look in.
