Canon 40D - EOS 40D DSLR Manual de usuario descargar pdf (Pagina 4)

s made obvious in the comparison picture above, the viewfinder is not the only physical

change Canon has made in the 40D Canon EOS 40D. The new 3" LCD is the in-your-face

change - or should I say in-your-nose since I have trouble keeping mine off of this new LCD.

I'm cleaning it much more frequently than I did the 30D's - and the 1-series bodies have

more nose relief (its eyepiece extends farther out the back). The new LCD is big, bright, has

good color and allows me to adequately determine image sharpness. Line up a 40D, 30D and

XTi/400D with the same image being reviewed and the 40D's LCD color advantage is nearly

as obvious as the size difference. I use image review on my LCD primarily for insuring that

the image I made is what I wanted - this LCD is more than adequate for this purpose. The

only complaint I have is that, like with the

Canon EOS 1D Mark III's LCD, I can't see the borders

of the brightness histogram when in bright sunlight. Canon: I request that a vertical bar be

displayed on the side boundaries of the histogram - maybe you can make it red.

new use for the rear LCD is previewing your shot in Live View mode. We first saw this

excellent feature on the 1D Mark III. Basically, you can preview your 40D shot just like on a

typical point and shoot camera. Enable Live View (a menu option - I leave mine enabled),

press the "Set" button (which raises the mirror and opens the shutter) and see the image live

on the LCD. Live View focus is manual-only with one exception. During Live View, the "AF-

ON" button can be pressed to enable autofocusing (the mirror temporarily lowers to make this

happen). The AF point(s) selected before entering Live View is utilized. To facilitate manual

focusing in Live view, a 5x and 10x zoom along with necessary panning functions are

available. At these settings, critically accurate manual focusing is very easy. Two "silent"

shooting modes are available in Live View. These are not truly silent, but are much quieter

than a normal shot. Also available is a live histogram when "Exposure Simulation" is Enabled -

he "Info" button then toggles this view on/off.

Live View is best used in a tripod-based situation, but can work handheld if your DOF (Depth

of Field) is deep enough to allow for the inevitable movement (think overhead shots). Another

great way to use Live View: Attach a computer via the 40D's USB 2.0 port, load Canon's

included EOS Utility software and take complete control of the camera via the

computer. The Live View display will be on your monitor, 5x and 10x zoom is available along

with panning the image, the focus can be adjusted using your mouse (switch lens AF on),

shot settings can be adjusted similarly and the actual picture can be taken with another

mouse click. Very nice - It works very well.

Shooting information can now optionally be displayed on the rear LCD in addition to the top

LCD. While it seems like a minor feature, there are some situations where this is quite useful -

such as when the camera is mounted high on a tripod (now you don't need a ladder to see

the top LCD).

he big 3" LCD has displaced the left-side buttons. The menu button went up, the rest

went down. Functionally, it just takes a little getting used to if the 30D-positioned controls are

what you are familiar with. The power switch is slightly redesigned and more-recessed. I

personally find it a little harder to use, but the change is insignificant.

Moving up we find a new button labeled "AF-ON". This button allows activation of AF with

the thumb - the shutter release half-press activated AF can be turned off. Many

photographers prefer the thumb-activated AF method. One advantage is that it eliminates

need to hold shutter half-pressed while recomposing the frame. I personally haven't seen the

light with this methodology yet, but there's always hope - and the camera gives us freedom

to be different.

nd moving up from there ... I thought I did something wrong when I took the comparison

pics - and was preparing to re-take them. Fortunately I checked the cameras first. Along with

the unexpected size difference (based on Canon's specs - more later), the 40D's top LCD is

sloped from front to back. This makes it easier to read in a more natural camera position.

nd on up ... The 40D has a built-in flash like its predecessors. The notable change on my

particular model is that I have to press directly over the latch on the right side while closing it

- otherwise it pops open again. There must be enough flex to prevent the latch from catching

otherwise. This is apparently an anomaly on my 40D body as others are saying their models

are not as particular.

he built-in pop-up flash is useful especially as fill flash. If your needs are for direct lighting, a

shoe-mounted flash (bounced) is usually a superior option. And to that end, the 40D sports

Canon's new hot shoe first seen on the 1D Mark III (see the top-view pic below). I no

longer expect to see the typical hot shoe paint wear caused by installing/removing flashes.

his design also matches the new flash foot design first introduced on the Canon Speedlite

580EX II

. Flash settings can now be controlled directly from the 40D's menu (when the

internal or a compatible external flash is used - only the 580EX II at this point).

he Canon EOS 40D has inherited the 1D Mark III's tabbed menu layout - I expect we will

continue to see this layout in Canon's future models. Even the custom functions are split into

4 groups like the 1D III - though there are not nearly as many options in each of these C.Fn

groups (24 total). I personally like the new menu design a lot - and standardizing will make it

easier to switch between the different camera models. What I especially like is the "My Menu"

option that allows up to 6 menu and custom function options to be placed on one menu tab

for quick access. Included on my "My Menu" are Format, Mirror Lockup and ... Clean Sensor.

My 40D arrived with a clean sensor out of the box. While this should not be remarkable, this

experience is not typical - and the new XTi/400D I bought to compare with the 40D came

with a VERY dirty sensor. But, thanks to the 40D's self-cleaning sensor feature (I'm sure),

I have not needed to perform a

sensor cleaning yet. This is after many, many lens changes

(including many outside) and thousands of frames taken. I'm impressed so far, but not

fully convinced that perfection has yet been achieved. Canon indicated to me that this is the

same self-cleaning system found on the XTi/400D. I found that unit to be helpful, but not

perfect. So if the information I received is correct and since I change lenses a lot, I expect
