p.1 #1 · p.1 #1 · Nex - Glimmering moire focusing technique!?!

Don't find focus peaking on my Nex 6 to be critically accurate, my normal technique for critically focusing is magnification.

I noted something however, when a subject with a bit of texture is in focus, there is glimmering moire type effect that happens! This in the EVF.

Over time I've found this to be very accurate.

Have you guys seen this, how do you find it? If not, give it a try!

Perhaps this applies to other mirrorless cameras too.

Thanks.

Funny you mention it.
I found it on my 5DC, with a small quirk however - every time the object appeared to be in moire it was behind the focus plane.
Weird?

Yes I've seen it on my NEX-6--and wasn't expecting to see it as I've got an A77 and thought it was the same viewfinder but I guess it is not.

Personally I use focus peaking + DMF + magnification quite often. Your described method does work, but since my Touit focusing is garbage until they update the firmware I use the combination of everything to get sharp shots.

yup, this is the method i use almost exclusively for focusing on my nex-7. works great for getting perfect eye focus on people.

Yep, this has been mentioned a few times over the last few years. Cranking up sharpening can help with this method.

I use it too, some lenses are better than others, mostly the sharper lenses do it, I first seen it in my Canon 1DIII's viewfinder with the S screen which will only be accurate if the focus screen is shimmed correctly or you get front/back focus, which can't happen with my 7, so that is a plus.
The subjects need to have fine detail for it to work.

All subjects have fine detail. You can't always see it.

Another thing you can do though I really don't use it myself since it bothers me slightly while composing is that you can set the NEX camera to black and white mode so that the yellow and red colors in focus peaking are more visible. You'll have to convert the raw file back to color later on though.

Typically what I use is a combination of focus peaking and magnification. The focus peaking just to get somewhat close then magnification to really make sure that the focus is correct.

Cheers, might give that a try.

Magnification for me. Some of my adapters got past infinity.

I've seen what you describe, but my best 'in focus shots' are at the 9.5x loupe on my NEX.

I also used this method on my NEX and like it more than the peaking, mainly because I don't like the way peaking obscures the actual view.

I could swear there was a comment on focusing screen misaligned...where did it go??

This glimmering moire is the focus peaking, isn't it? I'm confused. Do you have peaking turned off, and see the glimmer?

i turn peaking off yes. in high contrast situations the peaking will cover it up. the glimmering is much more subtle.

Ok, let me rephrase, fine detail with good contrast.

Check my previous post, if the focus screen is not calibrated(shimmed to the correct position)to be the same distance from the lens as the sensor(dido for the AF module) front or back focus will occurs.
Manufactures don't put as much effort into calibrating focus screens as they did with manual focus cameras.

I think I need some annual leave right about now
