Eye Control in Canon

[dreamtheatre]

The problem with incorporating ECF is that the viewfinder quality will suffer. It will become dimmer and I think there is no way you can have 100% coverage.
When ECF came out, Canon can't even incorporate dioptric adjustment together with ECF....not until the EOS 30 that is.

Well, as with their marketing strategy, Canon always test new technologies in thier 2nd tier product range. After collecting enough feedback from professionals and advanced ametures form the EOS 3, they decided not to have it on the EOS 1V. It should be reasonalbe to assume that it is unlikely to ever be incorporated onto a EOS 1 series body.

It is a shame as I love the ECF on my EOS 30...especially when doing flash photography. But I think results varies very extreamly among users. It is not for everyone.

The reason of not incorporating ECF into the 1 series is becos they're made for speed and accuracy and by having ECF it'll slow down its operation.

Until now i also never use ECF on my 30 in the field, at most just try it out by calibrating and testing.

As with any technology or process, it just takes some practise to get the hang of it

Sometimes i find ECF slow, in the sense when it does not focus on the point u look.

Its in the calibration.
Worked well for me though.

Maybe the next time then try it out.

Actually, the ECF helps a lot when you are taking action pictures. You can instantly focus on where you want the focus point to be without having to shift your lenses to focus lock or use the dial to choose a focusing point. It actually increase your chances of catching that shot you want.

My guess why they haven't incoporate it into the newer cameras is because of the bad feedback. Since going by the responses of this thread, many users probably don't know how to use it properly.

Yah...just like myself

The ECF is quite useless if you are "four-eyed".

This is not how it works. Once the AF has locked on a subject it does not move around again.

I use it with the EOS3 and its brilliant.

Yes, I agree. The EOS 3 is brilliant.

Anytime the Eye Control misbehaves, I don't blame the camera because it has it's accurate moments most of the time. I suspect it's placement/position of the eye. Moreover, I wear glasses.

But for me, i don't wear any specs or contacts.

Hmm... really? Where did you read/hear that?

True, the EOS 3 doesn't have 100% coverage but I wouldn't consider the viewfinder as "dim" or "dimmer" compared to my other EOS models (even my cheapo EOS 300V).

Anyway, I'm sure that over time, Canon would be able to obtain 100% field-of-view with Eye Control. Maybe they already have, and maybe releasing it in a future EOS model.

I've tried it on my 30 but sometimes not accurate, doesn't focus on the point u look at.

It may be that the EOS 30 has lesser computing resources for its Eye Control, that is, a grade lower than EOS 3. I'm not entire sure about it but I do know that, from EOS 3 brochures, that EOS 3 has lots of processor power/speed for its AF system.

If I'm correct, the EOS 3 has 1-series class AF system with the addition of Eye Control. Its AF is fast, and even with Eye Control said to slow down AF, the AF doesn't crawl. It's still blazing. (I'm sure I'm not exaggerating as other EOS 3 owners would probably vouch for it.)

I have the EOS 20D, and although this DSLR is newer, more modern, and more expensive, I would throw it away and keep the EOS 3. The EOS 3 is faster and more accurate in its AF.

I quite agree.

I have used my EOS 3 many times for events. Although any good event photographer should be able to anticipate what may happen and be ready to shoot it, sometimes the event doesn't unfold as we expected. The subject may shift, or come from another direction. It's times like this when I know others will be fumbling over buttons and dials but I only have to look at the AF sensor, and voila, it's activated! Yes, strictly no thumb and forefinger work at all.

According to Canon, it was said the EOS 30's AF speed is on par with the EOS 3.

I've heard that the laser tracking the eye movement can be harmful to the eye in the long run, is it true?

If I'm not mistaken, and I'm very sure I'm not mistaken, it's NOT a laser but infra-red light. We can't see infra-red light but it's everywhere in broad daylight as long as the sun shines.

If infra-red is really harmful, I'm sure we would have suffered the bad effects of it even before we bought our EOS camera.

Hmm... maybe AF speed is on par, but maybe not the infra-red detector speed/accuracy, or the processor power in determining/activating which AF sensor was looked at.

I don't know, I could be spouting rubbish, but electronic engineers would say that it's a possibility.

 

[Prismatic]

Actually, for me, the viewfinder of the EOS 3 is already bright enough. It's a lot better when compare to those of the DSLRs these days. But because I shoot a lot of low-light photography, I changed the focusing screen to Ec-R which is the new laser matte screen. It's almost 1 stop brighter the regular screen.

That's y in my earlier post i also commented that if it's like this, Canon wouldn't have included ECF anyway.

This one i'm not sure le. If the EOS 30 performs as well as the EOS 3, then might as well get EOS 30 and pay lesser.
