Want sharper images, is it my lens or camera? I utilize photoshop elements to enhance & edit my pics, but that gets a little tiresome on a big shoot. What can I do or buy that will give me consitently crisp, sharp photos? HELP! Thanks for your respose....and please trust me, my eyes are fine and its not a focusing issue for you jokers out there! :)

Kateri, All digital images require a certain amount of sharpening. Whether it Nikon, Canon, Sony. Doesn't matter.

First, what camera settings are you using? I mean, shutter speed and f-stop? Most lenses are at their best one or two stops below maximum, e.g., a 200mm f/4 lens will often be sharpest at f/5.6 to f/8. Most of my lenses have a maximum aperture of f/2.8 yet I shoot at f/5.6 to f/8 most of the time. Also, if your shutter speed is not fast enough and you don't use a tripod or other support you may have a very slightly blurred image. You should ensure that the shutter speed on your camera is at least the reciprocal of 1.5 times your focal length, e.g., if shooting a 70-200 zoom lens at 95mm, your shutter speed should be at least 1/180th of a second and faster is better. Also, are you shooting RAW or JPEG? If JPEG, you may be able to adjust the default in-camera sharpening. But my recommendation is to always shoot RAW if you want to make larger than 4x6 prints. Think of RAW as the true digital 'negative' and JPEG as a drugstore print. Finally, you can verify that your camera is focusing correctly by setting your tripod a couple of feet above, and back from, your dining room table. Put an open newspaper page on the table, aim the camera down, leave the lens wide open, use the auto-focus to focus on a particular word or sentence, and then take a picture. Verify that the AF is working correctly by looking at the image; the sentence you chose should be razor-sharp. If not, if something before or beyond is in focus instead, you may have a calibration problem. Hope this helps!

One more thing... Tamron makes some very good lenses, and some very mediocre lenses. However, shoot at a decently fast shutter speed at f/5.6 to f/8 and you should get the best possible quality out of the lens.

Kateri, Have you tried playing around with the Picture Styles on the XTi? You can use the presets, or customize them to suit your tastes. You might want to try the Portrait Style, with a little increased sharpness. Most people recommend against in-camera sharpening, and that sharpening should be the final step of your post-processing. In general, I agree. But I've found that the sharpening applied by the Picture Styles is more subtle and natural-looking than in-camera sharpening with other cameras I've used. Give it a shot.
