No, I wasn’t using a Tripod for my shots with LCD VF as well. Like I said before, the subject motion was less likely, so camera motion could be culprit but still with LCD, camera was struggling to focus on the point where I was trying to (the focus point that you see in my example shot). | |

Additional details to improve the answer

| Jan 10, 2022 at 3:19 | comment | added | programmer | So although it’s about technique and isn’t a hardware difference, which I didn’t point out in the first place, it basically boils down to the opinion that LCD viewfinder is generally less reliable to get sharp photos when compared to optical viewfinder unless you get add-on equipment because the ultimate purpose is to get a sharp photo and whatever makes it easy and reliable is better. You can get hand-held sharp shots with optical viewfinder whereas it’s much hassle with a LCD VF. Nevertheless, it is just a personal experience and may not apply as a fact. | |
| Jan 10, 2022 at 3:05 | comment | added | programmer | Reading up on your thoughts, I understand that: 1. You need a Tripod to ensure you don’t loose focus due to unavoidable motion once you’ve locked it, but in practical situations, you don’t always have a Tripod handy. With Optical viewfinder, you can skip this requirement and still get a perfectly sharp photo, particularly comparing them when trying to lock focus on some slender subject in a crowded scene. 2. Unlike LCD VF, Holding VF to your eye gives additional stability, which again makes the optical VF more reliable in my humble opinion. | |
| Jan 9, 2022 at 16:24 | comment | added | Michael C | You're also less likely to have as much camera motion when holding the VF to your eye than when you are holding the camera out in front of your body far enough to be able to see the LCD. Is the other image blurred due to being out of focus or due to camera or subject motion? I've found that it doesn't take much in the way of breeze to move subjects such as your example enough to ruin perfectly focused shots taken from perfectly stable tripods. | |
| Jan 9, 2022 at 16:23 | comment | added | Michael C | The difference may have been in your technique, rather than hardware limitations. Were you using a tripod with Live View? Tapping the LCD to set AF point might very well lead to inconsistencies between the distance the camera was to the subject when focus was locked compered to the distance the cameras was held from the subject when the photo was actually taken. | |

incorporated suggestion from comment section

| Jan 9, 2022 at 15:12 | comment | added | programmer | @MichaelC #7 Your words ring so true. Tripod helps a big deal. #3 You are better informed and definitely more experienced so I do not question the veracity of your statement, but in my experience, I was able to take sharper photos with the smaller optical viewfinder using single point AF almost every time whereas LCD live view finder failed me on several occasions. Here is a photo (unedited) taken through optical viewfinder, but the same shot was a disappointment/hassle with Live View LCD touch focus. dropbox.com/s/ix95ofxnkggouf3/IMG_8883.JPG?dl=0 | |

| Jan 8, 2022 at 21:48 | comment | added | Michael C | Re: #3. Live View shooting is no less reliable than Viewfinder shooting. The steps of the AF motor are equally coarse either way. You can just see the effect of this easier on the larger rear LCD than you can in the smaller viewfinder. | |
