Re: Inconsistent Sharpness Issue withCanon 5d Mark iv

Yes, pattern is evaluative metering mode.  I use one of either a single point or one that looks like a cross with the center square being the most common but able to move to the outsides of the cross as well.

Re: Inconsistent Sharpness Issue withCanon 5d Mark iv

what program did you use to look at the focal points and focus information in these images? Would love to know how you did this. I have often wondered after the fact where the focal point was located.  Thanks for sharing this.

It is a free plugin for Lightroom.

As a test, try shooting some portraits like you posted using One Shot AF and see if you are getting the same problem.

 

I am always looking to learn from others. I noticed that you convert your Canon RAW files to DNG. What advantages have you found?

Re: Inconsistent Sharpness Issue withCanon 5d Mark iv

To be truthful, I just import them into LR as DNG since it is adobe's format and I use exclusivley adobe products.  I wish I had a more impressive reason!! Smiley Happy

I also exclusively use Adobe products (Lightroom, Photoshop, Illustrator), but I keep the RAW files as-is (Canon RAW).   In that manner, I know that I have the original data as saved by Canon.

Re: Inconsistent Sharpness Issue withCanon 5d Mark iv

Hey Boyer!

 

I actually have the exact same problem and it almost killed my love of photography. I have a work-around for you, but it's not a perfect fix and I am still dying for the fix. I even sent my camera to Canon, paid $400 for them to say there was no issue according to their mechanical testing. I sent it to a private calibrator who does it all manually, it got a bit better, but really, photos are still foggy/blurry, almost like nothing is sharp. SO!! The good news for you is my work around that I discovered. I was told the live view uses a different focus system from the back LCD. Shoot with your LCD screen rather than through the viewfinder and photos will be TACK sharp nearly every time! But the sad part is the obvious... the LCD sucks for sports and motion. Hope that helps, please let me know if you find a fix! Only people with this issue will understand it. And Canon currently denies it exists, so we need enough people to point it out! This is an expensive camera!

 

Thanks,

You are correct that the LiveView focus system is different than the OVF focus system. Since it shows the image that the camera sensor is seeing it is not subject to any focusing errors that the OVF phase-detection system may be experiencing.

 

But it will not overcome many of the other causes of unsharp photos. We never did find out exactly what Ms. Boyer's problems were caused by.

His problem’s my problem as well, LCD does work better as a work-around, but currently not much of a fix for the viewfinder way of focusing. Many photogs have this issue right now. And many dont even know they have it until I show them.
