Canon EOS D60Canon updates their D30 Semi Pro SLR with a 6 megapixel sensor and other improvements, and sets a new low-price point in the process!<<Camera Modes & Menus :(Previous) | (Next): Video, Power, Software>> Page 10:Image Storage & InterfaceReview First Posted: 2/22/2002 |
Image Storage and Interface
The EOS D60 utilizes CompactFlash (Type I and II) memory cards as its image storage
medium, which should never be removed from the camera while in use. (Removing
a card while the camera is still writing to it could cause permanent damage
to the card.) The D60 ships without any memory card included, Canon rightly
figuring that purchasers will most likely either already own memory cards, or
want to purchase their own high-capacity cards without incurring the markup
for a bundled card. The table below shows card capacities and approximate compression
ratios for the various file sizes and types, assuming a 32MB memory card, purely
for the sake of reference.. Like the D30 before it, the D60 is fully compatible
with IBM MicroDrives.
A year ago, when I first reviewed the D30, I felt that a MicroDrive should be considered almost standard equipment with the camera. A year later though, flash memory prices have dropped enough that you may want to consider your memory options more carefully. The MicroDrives are still very fast, and their top capacity of a Gigabyte is only just now being matched by CompactFlash cards. On the other hand, CF cards aren't prone to damage if dropped, aren't sensitive to environmental conditions such as high temperature or humidity. Also, you may well feel more comfortable having your images stored on several smaller cards than one huge one, in case of a mishap.

The CCD RAW mode listed above deserves some explanation: This is a format that records all the data from the CCD, exactly as it comes from the A/D conversion process. It is lossless compression, meaning that the file is reduced to a smaller size, but without losing any data in the process. This thus preserves all the original data from the sensor, but is nevertheless much more compact than an equivalent TIFF file. (The effective compression ratio relative to final file size is about 2.4 to 1.)
NOTE that the D60's RAW format now automatically includes an embedded medium/fine
JPEG as well, which several of Canon's various software packages can extract
with a new button called "Extract JPEG." (RAW Image Converter
applet, TWAIN driver, Mac plug-in) This should provide a quicker workflow
for situations where your final file format is JPEG. (Although I think my
personal preference would be for the dual-file RAW/JPEG approach used in
the EOS-1D.)
The D60 has a USB port for (reasonably) rapid file transfers
to the host computer. - I say "reasonably" fast, because the USB
connection obviously won't be nearly as speedy as the FireWire (IEEE 1394)
connection on Canon's EOS-1D and the Nikon D1x and D1h.) Like the D30's
USB connection, the D60's is on the low side of average, speed-wise, as
I clocked it at 259 KBytes/second on my G4 Mac. The specifics of the USB
interface is that the camera will appear on the desktop of your computer
if you have the proper driver software loaded.
I confess to being a little confused over what constitutes a "storage class" USB device these days, as I'd previously understood this to mean that a device would auto-mount on a Mac OS 8.6 or higher or Windows Me/2000/XP desktop without the need for any additional software. In the case of the D60, Canon refers to it as "storage class," but it nonetheless does require driver software to make the connection. On Mac OS 8.6-9.2, Canon supplies a Control Panel called USB Mounter that lets the D60 appear on the desktop as a hard drive. This connection allows drag-copying of files from camera to computer, but not the other way around. Under Mac OS X, the D60 is apparently supported by Apple's Image Capture Architecture, but I haven't had a chance to try this for myself yet. Under Windows XP and Me, Canon supplies a WIA driver that makes the D60 a "storage class" device under those versions of Microsoft's OS. (At "press" time, I don't know what support may be offered under Windows 98 - I believe it to be a standard non-storage-class USB connection via a TWAIN driver. - Windows 98 doesn't provide support for storage class USB devices.)
Lost Images? - Download this image-recovery program so you'll have it
when you need it...
Since we're talking about memory and image storage, this would be a good
time to mention the following: I get a ton of email from readers who've
lost photos due to a corrupted memory card. It's tragic when it happens,
there are few things more precious than photo memories. Corrupted memory
cards can happen with any card type and any camera manufacturer, nobody's
immune. "Stuff happens," as they say. A surprising number of "lost"
images can be recovered with an inexpensive, easy to use piece of software
though. Given the amount of email I've gotten on the topic, I now include
this paragraph in all my digicam reviews. The program you need is called
PhotoRescue, by DataRescue SA. Read our review of it if you'd like, but download the program now,
so you'll have it. It doesn't cost a penny until you need it, and even then
it's only $29, with a money back guarantee. So download PhotoRescue for
Windows or PhotoRescue for
Mac while you're thinking of it. (While you're at it, download the
PDF manual and quickstart
guide as well.) Stash the file in a safe place and it'll be there when you
need it. Trust me, needing this is not a matter of if, but when...
PhotoRescue is about the best and easiest tool for recovering digital
photos I've seen. (Disclosure: IR gets a small commission from sales
of the product, but I'd highly recommend the program even if we didn't.)
OK, now back to our regularly scheduled review...
