Inserting the Memory Card
The LX5 does not ship with any memory card. With this camera, unlike some
others, this is not a fatal omission, because the LX5 has built-in memory that
will let you take a few photographs even with no memory card inserted. The
amount of built-in storage capacity is only about 40 megabytes (MB), which is
pretty minuscule compared to storage cards of today that can hold up to 64
gigabytes (GB), or about 1,500 times more. But if you’re in a situation where
you need to take a picture and don’t have an available card, 40 MB is a lot
better than nothing. (If you do record some images to the built-in memory, you
can later copy them to a removable memory card; see the discussion of the Copy
command at the end of Chapter 6.)
You shouldn’t rely on the built-in memory if you don’t have to, so you need to
insert a separate memory card. The LX5 uses three varieties of card: Secure
Digital (SD), Secure Digital High-Capacity (SDHC), and Secure Digital
Extended Capacity (SDXC). The image above shows all three of these, from left
to right, along with a special type of SD card, the Eye-Fi card, which I’ll
discuss a little later.
All three types of SD card are small, about the size of a large postage stamp.
The standard card, SD, comes in capacities from 8 MB to 2 GB. The high-
capacity card, SDHC, comes in sizes from 4 GB to 32 GB. The newest type,
SDXC, at this writing is available only in a 48 GB or 64 GB size, though its
maximum capacity theoretically is 2 Terabytes, or about 2,000 GB. What type
and size of SD card you should use depends on your needs and intentions. If
you’re planning to record a good deal of high-definition (HD) video or many
RAW photos, you need the biggest card you can afford. There are several
variables to take into account in computing how many images or videos you can
store on a particular size of card, such as the aspect ratio you’re using (1:1, 3:2,
4:3, or 16:9), picture size, and quality. To cut through the complications, here
are a few samples of what can be stored on a given card. If you’re taking RAW
images at the highest quality in the 4:3 aspect ratio (that is, the image is 4 units
wide for every 3 units high), you can store just 2 images in the built-in memory,
but you can store 9 of the largest JPEG images in Fine quality or 400 images of
the smallest size and lowest quality. I often use a 16 GB SDHC card. Given the
conditions just mentioned, it can store 1,260 RAW images, 3,680 of the largest
