There are many little things that will make the camera faster, but the two main settings are:
- Image display
- Memory card
Menu > Wrench > SCREEN SETTING > IMAGE DISP. > OFF
When the camera’s drive mode is in STILL IMAGE (single), the camera won’t take another exposure while generating the review image.
The memory card speed makes a huge difference. In STILL IMAGE (single) mode, the camera won’t take another exposure while saving the image to the memory card.
I did some test, empiric, since I used my watch for timing. I took the image of my desk and timed how long the orange LED at the back takes to write the image to the memory card.
- With an 8Gb Patriot SD class 10, it took about 5 seconds to write the image to the 8Gb Patriot SD class 10 memory card.
- Same image, an image of my desk, with a 32Gb SD SanDisk Extreme Pro took only 1 second to write the image to the 32Gb SD SanDisk Extreme Pro memory card (SanDisk Extreme Pro 32GB SDHC UHS-I Card)
The speed of the memory card is even more important when using the Burst Mode CONTINUOUS. The faster the card, the quicker the camera will clear the buffer.
- JPEG is the fastest to write to the memory card since it’s the smaller format. A typical file size is around 12Mb to 16Mb.
- RAW, especially the non-compressed, is slower than the JPEG format.
- A typical RAW non-compressed is 44Mb to 49Mb.
- A typical RAW compressed is 21Mb to 26Mb.
- RAW + JPEG depending on the size the JPEG and whether the RAW is compressed or not will be between 38Mb to 63Mb.
