Thanks to all the replies, wow, this is a very important check I do with Aperture3.

How does this check exactly work? Does the program calculate if the image is in focus some how?

I wonder because if all it does is show the focus points, all that tells you is the focus point was over the right part of the image, that does not guarantee what the focus point is over is perfectly in focus. It doesn't seem very reliable to me.

It seems like either way I would zoom in to see if the photo was in focus, although I can frequently tell even without zooming in.

I get what your saying Will. Just because the focus point is visible doesnt really mean if it will be sharp. Sometimes its just good to know you had the correct focus point selected on a given picture. It could also help with AI Servo and say zone focusing. That thing is all over the place. Knowing the lock ons will at least let you know if the camera was doing what you wanted it to do. Although we all know not to let the camera think for itself

that's true...but maybe he just want's to see where the focus point was

remember you can view the AF point used in body..so there must be something in the metadata that stores this

Does Aperture actually get the focus points from the Canon metadata in the same way that ZoomBrowser/DPP do? That's interesting because I'd thought that info was proprietary to Canon...?

Anyway, it's not all that useful to me -- I always just zoom in to check focus/sharpness -- checking the focal points has never been relevant to me because I know where I was focusing on just be looking at the shot.

I see, didn't occur to me because I rarely use more than single point or single point expanded. I have little trust with my camera when it comes to AF points.

Seems like it gets it from the metadata Tony.

Weird... I wonder why LR doesn't have this option.

wow man!!! I have not been using any AF mode at all except single point continuous its a shame I am not using one of the D700's strength

Nikon cameras shows it as well in camera Tony... only time I find it useful is if you wanna check your camera's AF

yeap same here ain't that what they teach around here?

Thats what happens when you are the leader and someone else is playing catch up. Usually the one playing catch up tries everything it can to one up the other. While the leader rests on their past successes.

I'm hungry and its 340am here

Well, I just don't find it very reliable. I have used zone AF at times on the 7D and it works reasonably well.

how good is Aperture's NR?

But DPP and ViewNX2 has this feature, you would think they would at least include all the features the manufacturers have right? Sounds crazy to me, BAD ADOBE!

if you have tried Dynamic 3D AF on the D700 you would go crazy the AF point will jump all over the place hehehe not sure if it really gets anything in focus...now hhmmm I should try it this weekend

I actually don't get the "Lose AF past f/5.6" thing... why? I mean I always shoot at f/8 or smaller w/ AF

but yes if you could afford the 500mm then why settle for less

I can explain

Your lens' aperture does not actually change when you change the setting on your camera. It only constricts when you actually take the picture. When you look through the view finder, the lens is always wide open. (Hence the purpose of the DOF preview button to actually close the aperture)

However stuff like teleconverters cause the lens to lose light even when you are not taking the picture because it is not the actual aperture of the lens restricting the light.

The AF sensor requires a certain amount of light to function. When the max aperture of a lens drops below 5.6, most Canon cameras lose AF because the amount of actual light getting to the sensor is too low for the camera to consistently achieve focus.

I don't know about Nikons either!

But some interesting info: the AF on the 1D bodies does work down to f/8 but for the rest it is disabled beyond f/5.6 but this is done electronically when the camera gets "info" from the teleconverter -- the TC "reports" that it is connected and so the camera turns off the AF. On the 1D bodies, at f/8 all but the center AF point are disabled.

People who like to mess with things turn off this "reporting" by taping over a pin on the contacts of the TC. That way the camera can AF. I've never done that -- for one thing I don't like to use TCs on "slow" lenses and figured that using them "improperly" won't do any favors to getting good results. But also, some TCs don't report -- I used to use the old 70-300 IS lens with the 30D and had a TC that would have disabled AF but as it turns out didn't report. So, the combo got AF but with not-so-good results.

But I do push things -- I told you guys about my birds yesterday and I used a TC with the 100-400 for that on the 1D3, meaning it had an f/8 aperture (I actually stopped down to f/11 for the shooting). That's one of the nice things about the 1D bodies, is that you can do that!

For those who haven't seen the results, I got some decent shots -- they took some sharpening in Lightroom, and I still needed to closely crop, but at least they weren't painful to look at. Here's the link if you haven't seen it and got bored:
