Things you may not know about the 7D.

Flare · 2nd January 2005

Was discussing about flash settings with TME on another thread, and thought maybe there are some other interesting things about 7D that's not mentioned or not obvious in the Manual. Maybe we could share. Or is it because i've never touched the film 7 before?

1. DMF works only when the AF mode is switch to Automatic mode using the focus mode selection lever on the front and after you have switched on DMF in the menu.

2. By default, the ev compensation dial is set to affect both ambient and flash ev. This can be seperated in the settings menu. Therefore, dialing ev compensation in M mode + flash would affect the flash output instead of being redundent.

... anymore? Or is it just me?

yup, especially the 2nd one. i find it can be quite dangerous. i've changed to only ambient.

I left it as ambient and flash. I find that usually when I do EC, I want to make the shot brighter overall, which means both ambient and flash has to be adjusted.

FEC would always be set to -1 EV or less and the shot will have the same flash effect instead of having to think about EC and FEC and how much of the 2 I'm applying.

Since the A1, the AS works best in Manual & Shutter Priority. When you're in Aperture Priority, you'll see the camera icon appearing at the bottom bar in your 7D VF. My work around for A mode is take the shot first or note the shutter speed when half-pressed shutter, change to S or M mode and set the same to shoot.

The icon is just a warning that the shutter speed is below the handholding limits. And it's not active in the S and M mode as these mode assumes that you know what you are doing with the the set shutter speed.

It does not improve the performance of the AS in any way. The effectiveness of AS is still determined by 5 bars on the right.

Hi, here's one...

As probably most user have know, 7D has a sensor that determines if you're shooting portrait or landscape because we all can see how the info panel changes when we rotate the camera.

However, when we take a photo, the orientation is never saved to EXIF of the image. As you know, nowadays certain software (ie. Adobe Photoshop, Adobe Photo Alboum) do pay attention to the EXIF info and automatically rotates your photos in the correct order.

Nevertheless, I realised that if while viewing the photo on the 7D viewfinder, you rotates the image manually (pressing the down button on the controller), you effectively changes the EXIF info (orientation property) on the image.

Hence, next time after you shoot some photos and while reviewing it, do remember to rotate any non-landscape photos so that you'll have a easier time while you are back home with your view software.

That means that FEC is always one stop lower than EC? And if EC is 0EV, then FEC is -1EV?

Hi,

Some pple may not know that 7D images are in an aspect of roughly 3:2, unlike many other digital cameras that have images in a 4:3 aspect. A 3:2 aspect basically means you can print 4R/8R photo with little or no cropping. Hence, you never need to specify super 8R.

You mean super 8R. 8R is 8" x 10" which is not 3:2 aspect ratio, but S8R being 8" X 12" is 3:2 ratio like 7D's image. i.e. you do not need to crop 7D images for printing in 4R and S8R (yeah, you'll lose 8 pixels on the long side, but what's 8 pixels)

How come you lose 8 pixels?

From where I came from, it has always been 3:2.

In this setting, flash exposure will always be 1 stop lower than ambient exposure after exposure compensation, no matter the amount of EC I apply.

Yup Yup, my set up is similar... and i M mode, the ev dial is easier to turn than the flash ev collar, so i just maintain the default settings

Hmm.... looks like it is a deliberate design with some good afterall.... no need to keep adjusting... but of course if the exposure difference is more than 1 stop between subject and background then u still need to move that collar....

Actually I dun quite understand Spurssy.... I thought most cameras come with 3:2 ratio? 4:3 is rather uncommon for 35mm, film or digital... thought it is more for the larger formats...

TME · 3rd January 2005

Thought I'll ask this question here... dun want to start a new thread just for this:

For 1GB CF card, how many Highest Quality JPEG files can it hold? And how many RAW?

Would it be better to buy more than one 1GB CF card or to buy say a 2GB or 4GB CF card? Which would be better in terms of reliability (u need to take the cards in and out more often if u use multiple cards) and cost?

Most digicams and Olympus DSLRs are 4:3.

Sorry my mistake, prob just 4R in this case.

OT!!!

Yo, when I logged in, for the 1st time (for me), I saw Minolta vs. Canon = 17 vs. 12

Minoltians nowadays are more active in forum
