[QUOTE="navcom, post: 87627, member: 11365"] There are many reasons for soft shots. Here's a few of them. See if they might help out... Camera shake. Yep...even at 160 you can have camera shake. This is especially true if you use longer focal lengths. The rule of thumb is the shutter speed should be 1/focal length. In other words. If you have a 200mm focal length, you should be shooting at 1/200 shutter speed MINIMUM. That's just a rule of thumb but you can see that just having something faster than 1/60th isn't a guarantee. Much more involved. Depth of Field. If you are shooting at wide open apertures, most focal lengths will have very little depth of field which can easily cause parts of the image to be soft or out of focus-looking. Diffraction. Inversely, if you are shooting with really small apertures (usually about f/18 or smaller), you can get diffraction, which makes the image look softer. Image Stabilization. Yep...even IS can cause blurring [U]if you are using a tripod[/U]. Hand holding, it will help. On a tripod, it will hurt because it is looking for movement where there is none. Digital sensors. Most digital cameras, regardless of the cost, produce images that are relatively soft straight out of the camera. It's not a lot but I shoot with a D600 and I've even used a Pentax 645D (medium format 40mp) and both still require a bit of post process sharpening for my tastes. Most of those advertisement images are sharpened a bit in camera while in JPEG mode so they can say it was "straight out of the camera". That doesn't mean that they are all really soft...most could just use a slight amount of sharpening in post. It's been my experience through the years instructing that the #1 reason students get blurry images is camera shake...even if it doesn't appear initially as the main reason. Most of us don't comprehend how much impact a little shaking can contribute, even at relatively faster shutter speeds. As a landscape shooter, sharpness is everything. I use not only a tripod but also a shutter release cable, the mirror-up option, and my shutter delay option on my camera...all as insurance to make sure there is NO shake. Hope that helps!
