KR Live veiw v Through the lens

I took these two test shots just now and wonderd if you could see any difference in the sharpness of the results. First taken through the veiw finder and second in live veiw.

DIfficult because the first one seems slightly underexposed but going on the pics as they are now the second looks slightly sharper round the number edges.

Yes Mike although the camera for both photos was left in auto mode they differ from 1/13 to 1/8 of a second.

Yep, the 2nd is a teenth sharper. I make lots of use of live view - more accurate AF and easier manual focussing, and of course there's no chance of mirror vibration. It also allows you to exploit more interesting angles.

Do you need to cover the view finder when using live view, to maintain the correct exposure metering?

Good question, i actually believe it can use the sensor as well to meter since you can show the histogram during live for example.

Live veiw.

Did you use the 2 second self timer to ensure lack of vibration?

There's no mirror slap anyway with Live View, so the difference just maybe could be down to that.

I assume it's down to focus though.
Live view is very accurate and does not have focus errors like front or back focus misalignment.

At that sort of distance DOF would more than cover any but the grossest focusing errors, so that shouldn't be an issue.

Hi John yes I did use the 2nd timer on the tripod for both however I did not cover the veiw finder eye peice.

Hence the slight difference in exposure.

It's not down to mirror slap then, so I can't think of any explanation just now.

The DOF also get smaller at these short distances so focussing get more critical, so any deviations in focus will be shown quite pronounced.

There is a simple way to test this.
Put the camera on a tripod and take a photo normally and then move the switch to manual focus and take a photo with live view, the focus will stay the same then so any variation is down to the use of live view then and not the difference between focus.

I don't see the distances involved here as "short distances" Stefan.

If it helps the clock was taken about 3 foot focus on the ctr winder. The garden photo focus point was on the left pillar at the front edge of the capping stone about 10 feet away.
