Canon A1 shutter priority exposure meter reading

[george_deacon]

<p>The A1's manual has slightly confused me about overexposure when shooting in shutter priority. I understand any aperture between f/19 and f/32 will always flash and overexposure depends on the lens minimum aperture. The manual says if the minimum aperture of the lens is equal to or smaller than the flashing aperture, exposure will be correct. So my question is, is smaller defined as a smaller aperture or smaller numerically? Both my current lens' have a minimum aperture of f/22 thus if the flashing aperture is, for example f/16 am I correct to think exposure will be correct? Conversely if the flashing aperture is f/32 my shot will be overexposed?<br /><br />Thanks</p>

<p>Yes - it only makes sense that way, understanding 'smaller' aperture to mean a physically smaller hole.</p>

<p>I think that is usual, but it is a little confusing sometimes.</p>

<p>I like to think of f/22 as a fraction with 22 in the denominator, so f/22 is smaller than f/16 in the same way that 1/22 is smaller than 1/16.</p>
