Hi.

I just got me a A2 and is wondering about something.

According to internet, the filesize is 6.9 Mb per image, witch make sense, as the A2 states that there is room for apox. 35 images when I put an emty 256 Mb card in the camera.

But when I take a picture the size is between 3.6 and 4.5 Mb per image, and in the end there is room for aprox. 60 images at the card.

Am I doing something wrong?

Henrik:

Your file sizes are about right for Extra Fine JPEG files at 3264 x 2176 resolution.

JPEG file sizes will vary based on the amount of details and color in a scene (which is what you're seeing). But,I've never heard of a 6.9mb JPEG file before (that's way too large). Someone might have estimated it too high.

Thanx's.



Then I guess, there is an flaw in the waythe camera calculates the file size.

I don't think it is fair to call it a flaw.

...from the A2 maual:
Quote:
The frame counter indicates the approximate number of images that can be stored on the memory
card at the camera's image quality and size settings. If the settings are changed, the frame
counter adjusts accordingly. Because the counter uses approximate file sizes, the actual image
taken may not change the counter or may decrease it by more than one. When the frame counter
displays zero, it indicates no more images at the image size and quality settings can be captured.
Changing those settings may allow more images to be saved to the card.
AFAIK all digital cameras behave similarly when JPEG file type is selected,

I know, but there is a big diffrence in the way the A2 calculates filesize, and the actual filesize, the images it is about halfsize off what the camera calculates.

A2 = 7.3 Mb average size

Real life = 4.3 Mb average size

It is some thing I can live with, I just find it wierd.
