		<description>Interesting, I have been reading studies that show that the general guidance is more often than not inadequate if you want to maximize the full resolving power of either film or a digital sensor when hand holding; you need to use a shutter speed one and preferably two stops faster - especially if you plan to enlarge to bigger print sizes.

		<description>Thanks for your comment and advice, John. Remember also that if your 28-50mm lens is zoomed to 50mm, the reciprocal rule would suggest 1/60, so adding a stop would bring you to 1/125.</description>

		<description>I have used the reciprocal rule for years. It works very well. Also keep in mind that mirror and shutter vibration will usually make a 28mm shot at 1/30 somewhat shaky in the detail. I usually add 1 stop to the reciprocal formula. (e.g., shoot at a 1/60 for 28-50mm lenses).</description>

		<description>@tukangmoto,

You&#039;re absolutely right, I completely forgot to mention that! I am going to amend the article to discuss Image Stabilization and Vibration Reduction. Thanks :)</description>

		<description>what about VR or IS technology ? i think they are broken the rules somehow :)</description>

		<description>@deuts,

I&#039;m glad that this was helpful for you! Just to clarify for the benefit of other readers, to find out what the multiplier is for your specific camera model, I find Digital Photography Review to be a great resource. Information about the 30D specifically was found on http://www.dpreview.com/reviews/canoneos30d/page2.asp under &quot;Lenses.&quot;

It&#039;s important to keep the multiplier in mind because cameras with cropped sensors such as deuts&#039;s 30D require a faster shutter speed to counteract hand shake than full-frame cameras. Happy shooting!</description>

		<description>Well, actually I&#039;ve read about this rule/guideline before, but I learned something new. That in my 30D I need to multiply the focal length of my lens (say, 85mm) first by 1.6 and that&#039;s the minimum shutter speed at which I can safely handhold my camera to prevent blurring. Thanks!</description>
