Anyone know how many times you push the zoom button to get to 100%?

I presume it's not the full way in?
 
Nope. Just the frame of the picture and white box to signify where you are in the shot. Size of white box changes the more you zoom in, but i can't see anything to tell you how much zoom it actually is.

Can't find anything on the internet either.
 
Assuming the 5D in your bag, a quick dig shows that your sensor is 12,800,000 pixels and your LCD is 73,000 pixels (approx)....ie, one displayed pixel represents 175 captured pixels (area).

At 2x magnification, this becomes 175/2 capture v display (area). Continue down that path and you'll get the answer.

Hi Dave, I've just checked on my 60D and 5D3 and from displaying the original size to full zoom is 15 button presses for the 60D and 15 partial turns on the 5D3. What percentage of the full zoom for each press is I don't know for sure but I guess each button press increases the zoom by 6.66%. I don't know how many presses it needs for any other bodies though, it may differ for different models.
 
I'm not convinced the last zoom in is at 100% though?

IIRC i remember doing the 100% zoom in LR, but thinking the zoom on the camera LCD went in a lot further, so i'm trying to establish how many pushes of the button does it take to replicate the zoom in of LR....IYSWIM. :D
 
OK, i THINK for every push on the button, the zoom on the rear LCD goes in 10%.

On LR with the zoom at 3:1, the size of the box inside of the frame of the shot, appears to be the same size as the box in the frame on the LCD, when fully zoomed in.

This means 100% zoomed in after 10 pushes of the button and 150% zoomed in at 15 pushes. Kind of makes sense in a way, but nice to be definite.
 
Well i'm sorry Bob, but i think i'm more confused than before.

:D
Perhaps I mis-understood your "100%" terminology. I assumed that you meant one pixel captured would be represented by one pixel on the LCD....ie, the equivalent of a 100% crop in software.
