Eye control autofocus effectiveness

Dear Sirs,

 

<p>

 

I own a Canon Elan IIE with the eye control feature, I have two calibrations for the eye control, one for situations when I'm using glasses and the other one for situations when I'm not using them.

 

<p>

 

I have found out in most of the cases the eye control is not as easy and precise to use as I supposed in both calibrations; I have to mention that using the calibration for glasses it's by far more difficult to use.

 

<p>

 

I got used to use my camera in other autofocus modes than eyecontrol.

 

<p>

 

Is this usual for Elan IIE users?

Can be a problem of my camera?

 

<p>

 

Thanks in advance,

Best regards.

I have an Elan IIe and wear glasses. Eye control works well for me,

but I have heard that not everyone has good results. Perhaps this is

due tot he shape of the glasses, or iris, color of the eye, who

knows. I do know that to get good results I have to recalibrate the

ECF every week. Don't erase the old calibration, just recalibrate.

In fact I usually do it twice, once looking over the top of the boxes

and once again looking under them. When I take the time to do this,

It never misses. I have found that for most of my use the single

center focus point is the one I want, so I often have ECF off anyway.

You can get an eye piece extender which apparently allows ECF to work

better for people with glasses, I do not think it will fit onto an

eos5, and as I do not wear glasses cannot comment on the

effectiveness, I also recalibrate my ECF in different lighting

situations about 1 a month max

I use the ElanIIe and wear glasses.

 

Calibrations are cumulative. As I have continued calibrating in as

many different lighting situations as possible, the camera has become

more responsive to my eye. In a Canon brochure they refer to this

feature as "self-teaching technology".

I have heard that people who wear LARGE glasses (mine are small)

sometimes encounter problems. I suspect this is because the camera is

comparing the cornea of your eye to stored images of your cornea, and

somehowlarge glasses interfere with this.

My eye-control feature gets better and better. I don't have to

always look at one of the three AF squares in the 'finder anymore.

When I look anywhere ABOVE the squares or at the height of the

squares, as though there were an imaginary line drawn across the

'finder right through the squares, the camera detects my eye's

direction and uses the nearest AF square to focus. This does not work

below the "line". A Canon service manager confirmed that there is

indeed a "window" in the area I described where eye control will work.

 

<p>

 

By the way, when you calibrate be sure to stare fixedly at the AF

squares and don't forget to calibrate it holding the camera vertically

as well.

Don't give up, it skates rings around regular AF once it knows your

eyes well enough.

Good luck!
