Conflicting reproduction ratio/magnification2009-07-04
Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro Lens for Canon Digital SLR Cameras

In the (Amazon-clickable) specifications for this product, it says the magnification is "up to" "3X." Elswhere, it gives the ratio as "1/3." Given the 6 inch closest focus distance, I expect the magnification is 1/3. If this is a 3x lens, then someone please tell me more!

Decent, but not great2009-04-12
Been using this lens for about a week now. Overall performance is Ok. The photos come out fairly sharp. However, when I switch over to my canon 50mm 1.8, the sharpness is way better than this lens. For more than 3x the cost, I would expect it to be close comparison, but I definitely love the sharpness of my 50mm a lot more. The other thing is that there is no IS on this. I gave my sister to take pictures and most came out to be blurry because I suppose she did not have steady hands. I also noticed that some of my shots were blurry due to the non-IS. If you have sure hands and steady, then this is a decent lens to have. I was shooting children and babies, so had to move around quite a bit, and the results were not good. The focus is not as fast as I would like either. I did like the fact that it came with a hood and a nice case. I really would like something as sharp as my 50mm that can zoom wide angles. I think I will be returning this one. Before this lens, I was using the canon 17-85mm IS USM. I'm spoiled by the IS and really feel unless Tamron or Sigma has that technology in their lens, I wont be switching over.
Just the lens I needed2009-04-10
This is a solid well made lens, f2.8, 7inch close focus approximate 1:3. I would like the lens shade to fit a little tighter. The pictures are great.
A great lens for the price2009-03-31
This lens is sharp and accurate. Its functions VERY well in low light and in up close, macro shots. Its awesome to have a minimum focusing distance of 8 inches! Since this lens serves two functions for me (low light and macro), I can't complain much.
The only things I didn't like are that its not internal focusing (but that's something I can get used to) and, every once and a while, it will take its time autofocusing. Sometimes, the lens will not allow the shot to go at all! Its not that much of a pain and is something you can deal with for the versatility and the price!
Good lens! Glad I bought it!2009-03-25
It is a really nice lens for those who can't or don't want to drop $1k+ on the comparable Nikon 2.8 lens. It has nice bokeh. My copy was tack sharp. Highly recommended!

Driving with a cell phone is a lot less dangerous than driving on prescription drugs
There's a lot of debate today about the safety of using cell phones while driving. Statistics show that those who use cell phones while driving cause a much greater percentage of accidents than those who avoid using their cell phones. And the studies have shown that it's not just the physical coordination required to punch numbers into the cell phone while you're trying to work the vehicle that causes accidents; it's actually the lack of attention resulting from driving and talking on the cell phone at the same time. It seems that when you're distracted, you're more likely to cause accidents. In terms of public safety, it's probably correct to say that banning cell phones would reduce the number of traffic accidents. But I think, more accurately, it depends on the person. Some people are operating on, shall we say, lower power CPUs in their heads to begin with. They might be zoned out on prescription drugs, and when you add a cell phone to the equation, they do become a danger to the ...

" For a list of all the ways technology has failed to improve the quality of life, please press three." - Alice Kahn This quote is certainly applicable to consumer electronics. From the very first commercially produced radios to the latest in high-definition television technology, the manner in which the components used to deliver our news, music, movies and entertainment are interconnected seems to have escaped logic. For both the newcomer and the old hand alike, connecting equipment in the most efficient and effective manner can be a painful chore. It is hoped this article will improve your background knowledge concerning potential A/V system connection schemes and where each is most appropriate. The next time you find yourself in a "connectivity quandary" perhaps the ideas shared here will help you to quickly solve the riddle of which wire goes where and why!
