    Hi
    I've just returned from a few days in the South of France on a photography holiday. I was very excited as I took my brand new 5D MK II. We were set assignments in groups and then at the end of each evening we reviewed our images. We got to review my images and zoomed into 200% and was totally stunned as all the images were really soft. My tutor, who is a professional photographer, had a look and was really quite shocked and said that this camera was well known for being sharp at 300% and I should get it checked out immediately. He also took some images and we got the same results. It can't be anything to do with camera shake, and the lens I used was the EF24-105mm f/4L IS USM which I got with my original 5D.

    Anyway, I wondered if anyone else had found the same problem?

    I purchased the camera from Warehouse Express as I get all my gear from them and they were extremely helpful and I'm sending it in tomorrow to be looked at. Am totally gutted as I waited for this camera for 18 months and now I have to let it go for a short while........

    Fingers crossed it gets sorted.

    Catherine

    Pixel peeping is a very dangerous thing, and anything over 100% is pointless. I think your tutor is talking from his bottom regards the 300% thing.

    But surely you want your images to be sharp?

    Why not post the image here, together with the camera's settings?

    So, all the other participants, do their photos look sharp at 200% or 300%?

    Hi Catherine

    As Paul says, anything over 100% is pointless and even that has limited value (agencies like you to do it but even an image that looks 'soft' at 100% is likely to be perfectly acceptable at normal viewing distances). In any event, all digital images require some kind of post processing including sharpening.

    Me thinks your tutor requires tutoring. If I were you, I'd post some images on here and get them looked at by people who do know what they are talking about and it won't even cost you anything Grin

    Hope you enjoyed the holiday Smile

    Why would you need to look at the file at 300%? I don't think I ever look at my photos over 100%...Unless I'm missing something...?

    Yes, but I don't need to to pixel peep at 200% to judge sharpness.

    Your pictures may or may not be sharp but it is difficult to judge without seeing something. Could you post a 100% crop here so we can see what you are talking about?

    They look pixelated, so they can never look sharp.

    You'll be hugely disappointed if you view any image at 300% no matter what camera it's from. That's not the way to view images nor is it the way to evaluate an images sharpness.

    Hi, yep will get a image uploaded as soon as I can.

    Having a slightly permissions problem with Apple's aperture, am not very lucky right now lol.

    I should add that when we looked at photographs that other people took and zoomed in they were much sharper on the cheaper Canon's. It's not really pixelated but just soft.

    Image to follow asap.

    RAW or JPEG? If JPEG then it depends also on what picture styles and even then if your camera is softer pixel by pixel it has so many more pixels it could still be a lot sharper. Consumer cameras are often set to have more sharpening by default. That is just processing. and I would think about getting a new tutor.

    How about processing and printing some images before you send it back as it is entirely possible there is nothing wrong with the camera.

    You need to compare like with like, cheaper Canon's have very different sensors so will look different, they may be outputting highly sharpened Jpegs against unsharpend RAW or Jpeg files from the 5D.

    I can only guess that the tutor was judging the amount of pixelation at 200% and 300% to determine sharpness - but it does seem a very odd way of working.

    I only ever use 200% or 300% if I need to do a very fine bit of cloning - and never to judge sharpness. Use 100% at most for that (if you have to)

    Just to show the difference between 100% and 300% crops. The first pic is a 100% crop from a random butterfly picture. the second is a screen shot of what it looks like at 300%.
