canon 1v vs canon eos-3

[Poisson Du Jour]

Yes, the sensor throws a matrice over the pupil to trace its movement, correlating that with the layout of the focusing points in the viewfinder.
Historically, some opticians have expressed concern about the idea of having beam so close to the eye but it appears nothing untoward has been reported.
It is the 'flare' of the beam that people interpret as reducing contrast. Ideally turn the whole silly thing off and concentrate on the image in front of the camera rather than the technology trying to do everything for you.

I notice the reduced contrast of the viewfinder whether the ECF is on or not.

The viewfinder just isn't as "snappy" as my 1V for manual focussing some of my mf glass.

More of an observation than a complaint really.

The EOS 3 is not the EOS 1V, Bruce. That's the difference, including the less optimally sized viewfinder than on the 1V (100%).

Try using a matte section screen.

Actually ECF does let you concentrate on the image before you and not the technology ;-)

With ECF I no longer have to use my right thumb to press on the [...] button then my right index finger and right thumb to pick and choose the appropriate focus point...I need only just look at the focus point and bingo, it gets chosen. ECF can simplify camera workflow and make shooting faster and more accurate too.

Allowing the camera to do some of the camera workflow for you is not a crutch, as some suggest...

Poisson.
I'm well aware of that as I'm shooting with a 1n, a 3 and a 1v currently. (not to mention 4 different EOS digi bodies).

The OP originally ask the differences.

Thought I'd mention it if that's okay with you.

And amazingly we also have this "old" technology around that allows you to twist a simple ring and achieve the same end result without the extra weight of motors and bulky lenses, fancy that.

True Clayne, however I'd rather use AF when shooting a fast paced wedding and reception ;-) Using focus points also helps in metering too...it's all good.
