Canon live view question 1212 Responses

i'm not a camera wiz but manual focus with zoomed live view has always been the sharpest. it is totally normal. unless you seriously think you auto focus is out of tune, then send it to canon. let them re-calibrate it for you. it will cost you of course.

Hi guys, thanks for the help, its the final pic that is sometimes not as sharp so i dont think its the dipoter. Cool, thanks Pango.. thats put my mind at rest. I am using auto focus with zoomed live view but i guess its much the same wether its auto or manual? I guess i should consider using zomed in live view in order to get the shrapest results.. i just hate using it!

The 50mm isn't the sharpest lens to be honest, and neither is the kit lens. It may look sharp on the live view, but viewing your shots at 100% on your monitor may disappoint. You need to invest in some decent glass for the sharpest of shots (sorry to say :o)

Yeah, i thought that was the case... its great or a £70 lens but yeah not quite a good as i would like. Time to start saving.

oh... depends on which camera, but note that some EOS cameras have a fuzzier zoom-in view on the back of the camera than when you actually look at the file in a computer.... also note that your computer's RAW view should have a sharpening algorithm... I've heard the 7D's RAW files look a bit odd fuzzy straight out of the camera until they've been processed in the right RAW converter... some don't correctly read 7D files yet so they default to a more generic converter....

Yeah its the 7d i have, i havent loaded them onto the computer so may look better on there. I was mainly the difference between zoomed live view and view finder that confused me.

wait... I re-read your post.... I may be completely wrong above....
If you get better results from zooming in and focussing using live view than you do with the optical viewfinder, even on manual focus on both, then the optical viewfinder's diopter may be off(as said above), or the viewfinder/mirror alignment may be off...
try this:
- first, try focussing using live view, on a tripod on a sharp object, then look through viewfinder and move diopter till view in viewfinder is sharp without changing focus on lens.if that doesn't give you good results, or change anything, try:
- tape a newspaper to the wall sideways, so text runs vertical
- find a line in it and highlight it with yellow highlighter
- place camera on tripod aimed at 45 degree angle to wall
- focus on yellow line of type using viewfinder, shoot images at F1.8, F2.8, F4, F8, with corresponding shutter speeds,etc...
- focus using live view/zoom, do the same aperture list
- focus using AF, single point, do the same aperture list...
-(use self-timer or radio trigger to be really anal about it)
- write down the image numbers for each to correspond...
- check images in computer, same RAW procedure for all....
- see if you are consistently too close or too far with the viewfinder, i.e. the lines in front of the yellow highlighted line or behind it... etc...
- if consistently off, then get your camera checked by Canon....- Dog-earMar 21, 10, 10:27 a.m. – Permalink

hi vaxorcist thanks i will head off and give that a try, one thing i havent explained well though is that its the shaprness of image is different (when viewed in playback) when using the viewfinder and zoomed in live view so i not sure what changing the diopter would do?
Cheers for the help and advice.

hmmm.. maybe I don't understand, but if the sharpness of the image is different when viewed in playback when using the viewfnider adn zoomed in live view, that may be just a software issue..... where there are two different algorithms to zoom in? not sure I get what you mean....
