I have a Canon 10 D that seem to be a little soft. I don't think it's the lens as it was sharper when I first got it. I load the shots on to my computer using PS 7. It's there that I notice the softness. Any thoughts??

man, every photo forum on the planet that's talked about 10Ds has talked about this. there's a lot of reasons why your images might be soft. for instance, shooting lenses without IS, shooting too rapidly with USM (after you focus, i've been told, there's a very brief period before the lens elements "settle down," shooting at too low of a shutter speed, clumsy hand-holding at slower shutter speeds, some after-market lenses, etc.

btw, very often digital images need a touch of sharpening in post. use the "unsharp mask"

The two biggest reasons for softness on any digital camera are caused by hand holding at too low a shutter speed, and focusing on the wrong element in the photograph (in other words, you place the focus sensor over an item that is really not what you wanted in sharpest focus. I used a 10D for over a year and I never had any soft shots that I could not trace to one of the above.

I use a tripod for all shots where the shutter speed is less than the mm of the lens. In other words with a 200mm lens I would not try to handhold at less than 1/200th. I also use the center focus only method, and I point the sensor at my target (what I want to focus on), then half depress the release and hold, then recompose and shoot. Keep in mind that when doing it this way that the focus point and the final place where the focus point in the camera comes to rest should be the same distance, otherwise softness can be introduced.

Here is an example of a soft focus shot, which I recovered using photoshop:



cheers,

I had this problem with my DRebel in the beginning, then I tried different Parameter settings, (contrast, tone, sharpen, etc)finally picking a compromise, in addition to using fast shutter speeds, I think I've eliminated it.

Maybe I've been fortunate, but I shoot with a 10D and have not seen any softness. The few problems I had in the beginning came from focus errors. Try selecting the center focus point, then be sure to place that on the specific point you want to tbe the center of your focus area.

Are they all soft or just some of them? A friend of mine was having focus problems with his 10D and we narrowed it down to it being his fault. I lock in the center spot and always focus on the eyes. I keep the shutter button held down after focusing and then recompose.

Yep, that's how I do it and everything ends up sharp.

Custom function 4 setting 1

Moves the focus form the shutter to the * button... you don't have to refocus every shot... and you don't have to get figure cramps while holding and recomposing.

The same thing exists on the nikons, just can't remember how to do it.

Doesn't exist on the rebel ( which is why I never bought one.

Not sure I follow you there. What do you mean? As for the CF, that's something to consider but it's another button to press.

If you hold the * button, then it doesn't refocus. Basically moving the AF button to a different button. Kind of a pain to learn to use, but it does work slick.
