Step Up To A Larger Filter
Q) I'm about to purchase a 28-75mm lens for use with my digital SLR. It has a 67mm diameter lens; however, I have a 77mm circular polarizer that I would like to use with the new lens. I also plan to purchase a 67-77mm step-up adapter so that I can use these larger filters on the smaller lens. My question is, how will the quality of the image be affected by not using the exact size filter required, i.e., a 67mm polarizer on a 67mm lens?
Q) On my camera, I have the option of erasing my images, formatting my memory card and doing a low-level format of my memory card. Which should I be doing?
Q) I just bought my first digital SLR; actually, it's my first SLR, too. I've been spending nights and weekends trying to learn all of the various features, but there's one feature that I'm just not getting. Depth-of-field preview doesn't seem to work-all it does is make the viewfinder darker.
