Canon 5D: So it's real.  And by the spec, looks very good.

While not "cheap" at an MSRP of US$3300, the 2 Lb 5D does promise a
lot:

Finally a spot meter.
Full frame.
Large monitor.
0.3EV ISO steps.

A few "odd" things:
6 "invisible assist AF points" within the spot meter circle...
1/200 sync.  (v. 1/250 in the 20D, not that important).
Viewfinder is 0.71x, but considering "full frame" that's
understandable, should be bright.
Dumped the AF assist light  (or was it via the built
                            in flash in the 20D?)
3 fps v 5 in the 20D.  (Proving again that high fps is not
                       that important)

Sample images from the source:
http://web.canon.jp/Imaging/eos5d/eos5d_sample-e.html

So?  Which D60/20D/10D shooters are feeling temptation... when the
price inneviably falls under $3K ... $2.5K ... do you leap?

Bret I bet.

Cheers,
Alan

nope, it's a separate device on the 20d.

What a lower fps rate on a higher resolution camera (50% higher)
proves is that memory cost would result in a significantly higher
price and likely limit the camera's appeal to a much broader market
most of which isn't professional sports photographers.

 I find that hard to believe, as memory is so cheap that compared to the
camera's price, it's near negligible.  For someone like Canon, who purchases
in quanitity, a gigabyte of memory wouldn't cost them more than $50 - and
probably less.   My guess would be that it's size-related, as in a camera
that small, every 1/2 square inch on the PCB is precious...

   Fast memory might cost a whole lot more, or the bus required to support
a larger cache of memory might the limitation.  In either case, it's not
commodity memory.

My guess is that they wanted to keep the features distant enough from
the 1D models so as not to erode sales of the higher-priced camera.

No, what it proves is that the small extra cost for more high speed
buffer memory would result in decreased sales for much more expensive
Canon models.

<snip>

Except that the 5D already has a bucket of buffer memory. Regardless of the
acquisition rate you would still get the 60 jpeg/17 raw burst images.

The cost of a higher acquisition rate would revolve around:

More analog outputs on the CCD (probably not a huge expense)

More A/D converters [channels]  (significant expense in $ and power)

Faster DIGIC (significant power consumption, possible heat issues)

Faster motors to recock the shutter/mirror (more power)

Most of these items would also result in additional volume/weight for the
camera.

My suspicion is that the camera was built to a price point with only a few
design givens (full frame, EOS 1 form factor, magnesium frame) and the
engineers added as many "professional" features as possible within those
constraints. The large number of images in a burst indicates that DDR SDRAM
is cheap. Spot metering is probably cheap to implement.

Instead of asking why they didn't put these things in, look at the minimal
differences between the 5D and the 1DmkII/n and wonder how they got the
price down so low.

BTW I also do not lament the loss of the built-in flash; I have a PS camera
when I need snapshots/redeye.

Was it really necessary to kill the onboard flash? Seems like an
*afforadable* FF dSLR (when the price drops) but has it been crippled
with 3fps rate and lack of AF assist? Will photo journalists be ok with
that low frame rate?

And where is the movie mode? ;-)

You know....I know you probably said that tongue in cheek...but I would love
to have movie mode on the D70. To me it doesn't make the camera any less
serious....and it's a bloody handy thing to have....

In fact, I would imagine that it would be huge selling point for any dSlr

I have a lot of friends overseas and would love to be able to shoot a few
little movies and send them...

I don't have any puritanistic arguements against more consumer grade
features in dSLRs but I don't think that the current electronics can
handle 30fps from a full-frame or even a APS-C sized sensor. Maybe a
new breed of microprocessors like the cell technology from IBM will
make it possible.

   Tis true.  Like leather in a truck, it's an unlikely thing to love.

   Anyway, I have a feeling that the mechanical shutter, combined with a
sensor setup that maximizes data collection from the full frame at one time,
makes a downsampled movie mode much harder to integrate.

Why not put another small CCD/CMOS sensor that moves in place between
the mirror and viewfinder's optical path when the movie mode is
switched on? Just wondering aloud, don't really know much about dSLR
construction.

   Because it would probably be much more cost effective to pocket a P&S
camera instead.  :o)

Not sure about cost effectiveness but sure lets you sell a dSLR, P&S
and handycam to the same guy ;-)

It should also help to solve my problems in getting precise focussing in
using my 10D for photomicrography. With a poor screen (for manual
focussing) and the inability to open the shutter to focus from the DV
output, it really isn't as useful as it ideally should be.

The 5D is supposed to have an optional screen made for critical focusing...

Yes, I saw that. However, they mention (IIRC) a choice of 3, and I have
a nasty feeling they will be something with split image wedges and
microprisms. These are in my experience little better; what is required
for critical focus in the kind of applications I have in mind is the old
"I" screen, with a clear centre spot and cross hair. This is the only
one which is really satisfactory on my 1n.

Also, the advantage of focussing from the sensor is that it eliminates
any possible errors from misalignment between the sensor and the
focussing screen. The disadvantage may be lower resolution of the video
output.

At the moment, all too often, I have to fiddle around with focus
bracketing. The margin for error in photomicrography is as near zero as
makes no odds.

In the "white paper:"
http://www.robgalbraith.com/public_files/Canon_EOS_5D_White_Paper.pdf
it shows all three screens, the Ee-S Sharp focusing Screen shows not split
image, and the write up says it has "finer microlenses than other two types,
meant for lenses f2.8 or faster, with a steeper-than-normal parabola of
focus for easier manual focusing."

I agree.  I use the movie mode on my Sony 828 on a regular basis; it's
great for making short clips for web sites.

I'm looking forward to a camera that merges what's great about the
Canon DSLRs (great image quality, low noise at high ISOs, 3+ fps
shooting, interchangable lenses) with what's great about the Sony 828
(30fps movie mode, impressive Night Framing mode, and (gasp) framing on
the LCD.

It's just a matter of time.  Heck, I remember when the nay-sayers were
ranting that digital cameras would never displace film for professional
shooters.  :-O

Yer gonna have a long long wait for all three of those on one camera.  Movie
mode, maybe, but "Night framing mode" and framing on the LCD probably will
be non starters for a long, long time.  The viewfinder does just fine, and
it would take a complete redesign of the camera to get the LCD to give you
live preview.  The shutter/sensor/lens/back setup prevents this, and it
really is unnecessary when you use the viewfinder, which is less affected by
ambient light than an LCD would be.  And, since it doesn't have pixels, is
more accurate, if somewhat smaller, for focus.  So, if you've checked your
focus in the viewfinder, why do you want to frame it in the LCD, since it's
already framed in the viewfinder?

Onboard flash may have affected the viewfinder coverage, and most of the
users won't miss it, we have shoe mount or off camera flashes, anyway.
Frame rate is similar to 1Ds mkII, so that may be a function of the sensor
size, not a "crippling."   Canon probably feels it doesn't need AF assist,
if you're shooting in low light, you'll probably have either a fast lens, or
a flash mounted.  Canon's flashes have their own AF assist lights, and
better ones than are on the cameras.  That being said, the old A2 had a very
nice AF assist light, near IR, that worked very well.  Canon hasn't produced
one as nice since.
And don't expect the price to drop much, or soon.  Look at the price of the
1Ds mkII, not much change there, percentage wise, the 1D mkII has dropped,
what, 200 bucks?  5%?  As has the 20D, a year after its intro.

After owning a dSLR for a year, I found my preference is to enjoy the
flexibility offered by a dSLR alongwith the superior low-noise sensor
but without carrying too much baggage around. So no onboard flash means
no flash for me as I am very less likely to carry an external flash
around.

Ofcourse, your usage and preferences may vary.

I have a Tamron 519 top loader, the camera fits neatly in it, and the 420EX
flash fits equally neatly in the outside pocket, with its attendant
Lumiquest Pocket Bounce.  The weight difference is negligible, and in going
without a flash, aren't you going without some of the flexibility, too?

Don't get me started on dSLR bags ;-) I agree that my 300D's onboard
flash has very limited capabilities (other than stunning the subjects)
but I like to travel as light as possible. So yes, I am sacrificing
some flexibility for convenience. As a sidenote, the Leica Digilux 2
has a cool onboard flash that other manufacturers can copy.

dylan - 26 Aug 2005 09:50 GMT
I'd like to see the size of the AF sensors, hopefully not the oversized ones
of the 10D, and multi-spot metering (maybe this could be a software
add-on?).
