Canon prime Focus

[Earl]

As i have two Canons now, boom boom HAHAH... cough... yeah ok...

Is the Focus point the same for both?

[brianb]

Well it should be ... in practise there may be a very small difference, but you're unlikely to notice unless you're working at a very fast focal ratio - the fatter light cone is less tolerant of focusing errors, and the cameras are intended to be used with lenses up to f/1.2 so they should be very accurately adjusted at the factory.

They will be close but not perfect because of small mechanical and optical variations. One of the reasons why the newer models have the microfocus adjustment built into them

[Psychobilly]

Reading you sig is one standard and the other modded?

If they are then there is a pretty good chance that the difference may be a bit bigger the difference depending on which "mod" has been performed...

I found that when my 350D had its filter removed it had the effect of 1mm more inward focus on my 250px.

Cheers for the answers.

As i was hoping it will be close

The only problem you will have with the modded 300d (filter removed?) is that standard camera lens don't focus. Great when used with a telescope....

It focuses fine with my 18-55

[Merlin66]

That's good.

It must have the orginal Canon filter replaced with a Baader UV-IR cut off filter.

Focus point is the same on my 550D and 5D, I can use the live view focus on the 550D to make sure I'm focused on infinity, I then tape up the focusing ring to stop it moving and then transfer the lens to the older full frame 5D.
