Well, since you asked nicely:
...faster is always better, as long as it could be done without sacrificing image quality. If not, leave it alone.
...same as above; if it can be done without sacrifice, do it. Low light capability is always a nice thing to have.
...I've never needed anti-shake, either in-camera or in-lense, even when shooting action sports, though it might benefit others.
...a bigger buffer would definitely be a big plus, for me anyway. This is especially true with the SD14. With the faster response of the SD14, when compared to the SD9, I'm shooting more frames now, and loading the buffer more quickly. While I don't often have to wait for the buffer to clear, it happens enough that it's an inconvenience during some sessions.
...same as above
...with the cheap(er) clone batteries and the new battery loading system, changing batteries is not the issue it was with the SD9. I wouldn't mind staying with the current system.
- sealed (water and dust) body
...I've doused the camera in salt water a few times, with no problem, but better sealing is always a plus.
...a few more focus points would be great, especially if the new ones were located in the "thirds" area, (three rows of three points)
...the current system works well, especially since SPP pretty much solves anything I may have missed when setting WB.
...don't even THINK of touching the current shutter! It's perfect.
...metal is old-school. It bends, corrodes and so on. Modern plastics work just fine. But if Sigma want's to go all modern and wild, how about carbon-fiber?
...as mentioned at the top, if it can be done without lowering image quality, the more the merrier.
...the size and function of the LCD works fine the way it is, IMO.
...it may not be possible, since it involves a mechanical lens function, but it would be nice to have a "hot button" option that would allow me to toggle between manual and auto focus without having to mess with the lense button.
And maybe an AF override function on the shutter button that would stop and hold AF.
And a bracket AF limiter that would prevent the AF from going all the way to the stops when focus is lost.
How about a software function that would allow the user to calibrate the RGB mix in camera? My "originals" always have a slight greeen tint that I have to kill in SPP. Being able to set a default in the camera would save a lot of time.
Maybe a choice of focus screens, easily changed?
Anf finally, maybe a focus calibration adjustment in-camera.
