In my last column, I tackled a question about shutter lag. The reader was frustrated with his camera and how the shutter-release button caused problems. “When I take pictures, it seems I have to press pretty far on the shutter button to get the camera to take a picture. Because of this, I have noticed that my having to press the shutter down so far seems to add movement to the picture and this shows up as blur.”

For example, you should disable stabilization when your camera is mounted on a tripod. The image at top was taken with the camera on a tripod and stabilization…

While you can use lenses designed for "full-frame" 35mm-sized sensors on smaller-format (APS-C) sensors (subject to the telephoto, or magnification effect), the converse isn't true. For example, the Canon EFS 18-55mm IS, included in the EOS Rebel XS kit, is designed specifically for use with APS-C-sized image sensors, like those used in the Rebel series.

Photography is a hobby of mine and I recently began researching submitting photos to stock companies. However, I have some questions about releases. Model releases are self-evident, but property releases seem a bit more complicated.

I typically use my camera in automatic mode, but occasionally I step out of my comfort zone and move into some of the other modes. I really understand the full manual mode but, quite honestly, I don't get the whole aperture priority and shutter priority. I know what they are supposed to do and I sort of get when you are supposed to use them, but when I take pictures, I often switch between the two and I really don't see much difference. Is it me or the camera?

While searching online for a mid-priced, 67mm circular polarizer for my Nikon D200, I came across this filter description that has me puzzled: "Used like and gives the same effect as [a] polarizer, but designed for cameras with beam-splitting metering." Is this filter a polarizer? How do I know if my D200 has beam-splitting metering, and if I use this particular lens with my D70 or something new later on, will this filter no longer work? Is this a concern for all circular polarizers, or is this model by Tiffen something special?

About a year ago, you helped me decide on an SLR camera, and I love it. I've taken a short camera class only to learn there's so much more to learn. Now I want a versatile lens, so I can carry just one lens with me. I'll need a zoom (150mm to 300mm?) as I'm sure to be far away when I want to take pictures of tennis players and capture action shots. I know from friends that the lens can't be too long or you can't take it into sporting events, and I need a lens with stabilization. Also, I teach first-grade speakers of other languages, and I enjoy taking their pictures, too.

This Article Features Photo Zoom It's tempting for photographers who want to travel light (and economize) to seek out the "perfect" zoom lens that will tackle all of their favorite subjects. That's a tall order, though, because desirable lens specs for sports photography are different than those for portraiture, for…
