I have a pessimistic view of the flood of memory card types. It is all about money. Here is one example. Sony came out with the memory-stick and now any company that wants to make a memory stick must pay Sony a fee to do so.
Look behind any of the new formats and you will find a company getting a fee for licensing that format to others.
For the consumer, the Compact Flash sells for the lowest price.
Shutter speed is a problem for digital camera makers. Not the shutter speed itself; but the delay from the time you press the button, till the picture is taken.
The first delay is for the time it takes for the camera to autofocus. That is usually in the area of one second or more.
The second delay is after focus is achieved, it takes a short bit of time to record the data on the memory card. This can be as short as 0.1 second and as long as nearly 0.3 seconds.
The consumer complaint is always: "When I try to take an action shot, I miss the peak of the action."
It took the film industry over 100 years to produce a truly fast action camera. It will take the digital industry a bit of time to do the same.
But they will find a way. Some camera manufacturers are starting to use buffering to speed up the recording process.
Right now, look for a camera that can autofocus in dim light, and do it in less than a second. That same camera should complete the picture after autofocus in 0.1 second or less.
Most cameras let you press the shutter switch halfway to achieve autofocus and then actually take the picture when you then press the button the rest of the way down. This lessens the problem of missing the peak of action.
Can anyone explain to me the difference between, Compact Flash Memory, SD Memory cards and Memory Sticks? Which is the most recommended?
How does shutter speed work and what should I look for in a dig camera.
