Focus Query

I've been using my new Canon 77D with the 18-135 lens. I've noticed that the images look beautifully clear and sharp when viewed on the camera screen, even when enlarged, but once uploaded to the computer they are fuzzy and out of focus. Can anyone explain why this is so? I haven't noticed this using my other cameras.

Are you shooting RAW? Perhaps the camera is applying sharpening etc to the jpg in the camera. The RAW - transferred to the camera - wont have any processing done to it.

Hi Sausage. Only jpegs at the moment as I've yet to upgrade my software. I'll try again later. Smile

Out of interest what photo viewer are you using?

The only reason I asked, is when I upgraded to my Pentax KP 24mp from 16mp, Windows Photo Viewer rendered the images weirdly, the images were scaled to match my screen but looked fussy like there was an issue between resolutions, hard to explain but caught between displaying the pixels clearly.

I now use IrfanView and can clearly see the difference if I compare to Windows Photo Viewer.

Hi Rick. I upload into Elements 14 catalogue, but don't store them there. I'm just so surprised at the loss of quality in viewing and processing the jpegs. I'm upgrading to E20 later so perhaps that might fix it.

In the meantime, have you tried comparing with any of the 'free' photo viewers?
I use Irfanview. Never had blur problems with jpegs.

You can't trust what you see on a camera's tiny LCD screen, which compared to your computer monitor is very low resolution. Also, camera manufacturers design their screens to render jpegs to make everything look fantastic, so that you'll buy the camera.

I'd suggest you look to your camera rather than your computer software, because it sounds to me very much like a focusing issue.
It could be something resulting from your lack of familiarity with a new camera... so, user error... or it could be an actual fault in the camera.

Surely nobody bases their purchase on that criteria ?

The only chance I get is taking a few shots in the camera shop and more interested in handling / focussing etc. than what the in camera monitor shows.

I would think that this is very likely. The vast majority of people buying cameras are NOT professional, or even informed amateur, photographers. They think that 'what they see is what they get' and are totally unaware of what the difference is between a Raw and a Jpeg, let alone what may be shown on the camera screen and what is/is not possible with software.

You wouldn't think so, would you?
But I actually know someone, an ex-EPZer, who bought a new camera based on the sole criterion that it was a particular colour.

Everything OK now. I do have to get used to the new camera and lens though as the dof is quite narrow compared with what I've been used.to. At least my software upgrade is all done now, so think I just need a bit more practice with the equipment.
Tks folks.
