Expected SX50 shutter life

I read your suggested explanation. Seems to make partial sense. IE I'm partially right, but not completely! Clearly my 4/3 G3 does not have a shutter because I can see the sensor and I don't think there is a shutter blind lurking there! Not sure about my D5100, because of the mirror, but will take a look see. (Am traveling w/o either camera so cannot verify for sure.)

Just another thought on the shutter no shutter issue with digital cameras. I think true DSLR cameras do have a shutter, but all other digitals (including my G3) do not. Reasoning is related to lag time. DSLR's have virtually no lag time, but all other digital cameras have some. The sensor is the reason. Pressing shutter release, the sensor must first calculate focus and instruct the focussing mechanism then determine the correct exposure and only then can it record the image data. Film SLR cameras have a sensor in the reflex housing to determine focus and exposure, so when the shutter button is pressed, the mirror flips and the focal plane shutter releases. DSLR's mimic this arrangement, so the data recording sensor does not have the extra work (time) required to focus and determine exposure.

Exactly. DSLRs have shutters and mirrors, m4/3 cameras have shutters but no mirrors and bridge cameras and point and shoots have neither. Shutterless cameras do not shoot as quickly as those with mechanical shutters (or at least they didn't) but one great advantage is that you are not limited to slow shutter sync speed.

What is the delay like on the SX50? Reading and looking around, this camera seems like the best thing since sliced bread, but a significant delay could spoil it for me. I do a lot of coverage of kids events at church, and my current P&S is such a pain... I press the button, but by the time the camera makes its mind up, the kid has zoomed by!

One of the greatest improvements of the SX-50 from the SX-40 is the shutter delay has been greatly improved. I usually have mine set for RAW + JPEG and the delay is very minimal for a P&S camera.
