Focus mask values. Method to compute best entries?
Hi all,
I have and a 5DIV (50mp, no AA) and now 5DIV (30mp, AA). So for this discussion would like to walk away for us and later readers that may find this to use the parameters of the camera they may have and know how to set them.
So for my specifics. I have 70-200L MKII, and 14, 35 and 85 sigma ART series lenses. You pretty much can't find sharper.
I have tried to use a 100% view on the eyes that are perfectly in sharp focus as a guide, but it doesn't seem to work well as a general setting as the algorithm doesn't seem to be strong enough to really rely on what it finds for other photos. Or am I wrong and I should take heed to the masks or if the algorithm is so weak not even use.
I also ALWAYS mix up what is the mask color, (in focus or out of focus areas).

I wish it were more useful. It seems like a good feature but it just doesn't work very well. 0 -
I use the Focus mask for more or less all my own shoots.
The trick is to adjust the threshold for the camera you are using, and the iso used for the image.0 -
I only have one camera that I use it with and I'm typically at the same ISO. For the feature to be really useful, neither of these should matter, but there's more dependants that that even. The brightness of the shot, the sharpness of the lens also matter. If I'm shooting wide open and the image is softer, it matters. By the time I adjust for all of these things, I realize it's not worth the effort. I work in QA for a living, and it may pass verification, but not validation. 0 -

I only know the dialog in Edit->Preferences->Focus. Is there a simpler/faster method to adjust the focus mask threshold?0 -
In my experience so far, this is the only reliable and expedient way to judge focus on up to 12 variants at a time:

If your subject is stationary in the frame across multiple exposures, there's no need to go and align the frames manually.0 -
Without a doubt, that is best. I don't know if the feature in C1 could ever be that good. It could be better than it is though. 0
