Great Lens
2008-11-23This is the best lens you get for the money. I can't believe how great and easy it is to use. I used it to take pictures of my son playing soccer and I could zoom him right up and get close up's that I could not have gotten with a regular lens. Love this lens..................

Canon 70-300mm lens
2008-11-22I received the Canon 70-300mm lens quickly from Amazon.com. Their service was great. I haven't had the chance to use the lens much yet, but know I will love it.

Dissapointed
2008-11-21I am a Canon fanatic and own many lenses and this lens is the one that does not give me that happy glowing feeling. I bought it primarily so when I went to sporting evens I could get closer into the action - I tend to buy seats close rather than sitting at the back of the stands and I am frustrated after a year of ownership.
At 300mm the lens is blurry, it seems to produce inconsistent color when I use bursts (1-2 pictures out of ten come up dark.....?) and it can be slow to focus. I thought I would be able to use this for nature photography however without the predictability of baseball I am not sure I'd be able to snap a birds that might land quickly and dart away again.
Its just not up to the quality of my other Canon lenses. I also think it is shameful that it does not come with a hood considering the price - you can tack on another $40 for that. When all is said and done you may find something similar from Sigma or one of the other producers that is cheaper and of similar quality. I personally wish I had gone that route for once.
It is not bad ... its just not great. I'm looking for a replacement.

Canon comes through again with another great product!
2008-10-30Great and powerful lens! I used it with the xsi and will with the 50d. The pics so far are ourstanding. I do think it's a little pricey but the IS system is worth it.

Great IS and Bokeh
2008-10-24With this lens, I can capture very nice pictures of my kids/nephew/niece. The IS work wells. Handling is good. Bokeh is what I expected.
The only thing that I like to have is the Full-Time Manual Focus which it doesn't have.

Intel's Core 2 Duo is easily the best mobile processor on the market today, boasting sky-high performance and low power consumption. But which CPU is for you: the super expensive T7600, the bargain-priced T5500, or something in between?
This article will first take a look at the various versions of Core 2 Duo that Intel has to offer. We will compare Core 2 Duo clocked at four speed grades: 2.33GHz, 2.16GHz, 2GHz, and 1.83GHz in a variety of benchmarks and let you know how to get your best bang for the buck.
Note: We will refer to a Core 2 Duo “T7000�multiple times in this article. We were unable to get a Merom sample with 2MB L2 cache, thus we lowered the clock speed of our 4MB L2 model to 1.83GHz to perform near that of the T5600 (1.83GHz, 2MB L2 cache), resulting in our unofficial “T7000�nomenclature.
The Core 2 Duo Processor
Intel has two lines of Core 2 Duo processors: notebook and desktop. Core 2 Duo for notebooks is codenamed Merom, while Core ...

It's worthwhile to white balance every time you use your camera to get the highest quality video. If your camera doesn't have this feature, it may have an automatic or internal system. What white balancing does is adjust the intensity of the colors being recorded according to the existing light. Make sure you white balance every time the lighting conditions change; if you record video inside and then go outside, your lighting conditions have changed and you need to instruc ...
