Canon EOS Camera Linup

!±8± Canon EOS Camera Linup

The Canon EOS System is composed of Canon EOS camera bodies, lenses, Speedlite external flashes and several lens and camera accessories. This article will discuss the current line-up of Canon EOS camera bodies.

Canon has varied line-up of nine digital SLR camera models. The current production line-up includes four entry-level, three mid-level and two professional level bodies, though some would argue, the Canon EOS 5D should in fact be considered a pro level body. Only the lack of a weather-sealed body keeps it out of the professional ranks, although none would argue that its image quality is certainly up to "pro" standards. Of course, these level designation refer to the camera's features. There are numerous professional shooters using Rebel XTs and 40Ds. On the other hand, even 1Ds Mark III in inexperienced hands can produce rather poor images.

Entry level Canon EOS Cameras

Canon EOS Rebel XS (Canon EOS Rebel 1000d) - Canon's newest entry level DSLR. Canon apparently created an entirely new level of entry level camera. Combines features from the last three Rebel models. Features a new 10.1 Megapixel CMOS APS-C format sensor, a seven-point auto-focus system, and continues the trend of recent Canon EOS models by incorporating a 2.5 inch LCD Live View screen.) - Canon's oldest entry level DSLR, and is believed to be in the last stages of production. 8.0 Megapixel CMOS APS-C format sensor and a seven-point auto-focus system.

Canon EOS Rebel XT (Canon EOS Rebel 350D

Canon EOS Rebel XTi (Canon EOS Rebel 400D) - Replaced the Rebel XT. 10.1 Megapixel CMOS APS-C format sensor and an new nine-point auto-focus system. Also benefits by the addition of a larger 2.5 inch LCD screen.

Canon EOS Rebel XSi (Canon EOS 450D) -Replaced the Rebel XTi. 12.2 Megapixel CMOS APS-C format sensor and a refined nine-point auto-focus system. Also includes a brighter 3 inch LCD screen with new Live-View technology.

Mid-level Canon EOS cameras

Canon EOS 30D - Replaced the older Canon EOS 20D. 8.2 Megapixel CMOS APS-C format sensor, improved nine-point auto-focus system, and a step up from the 20D with a larger 2.5 inch LCD Screen.

Internet and Tv relationship - Fiber Optic Rules! Movie aside - Cable

!±8± Internet and Tv relationship - Fiber Optic Rules! Movie aside - Cable

For years we have subscribed to a cable service both for our Tv and the Internet connections. It terms of the Tv service, it was okay. It did not deliver zillions of channels but just adequate to keep me busy during the few hours of the day that I watch Tv - mostly the History Channel, Discovery Channel, Cnn, Espn, Amc, Bravo, etc.

The real qoute was with the cable.

In ideas cable is supposed to deliver fast Internet relationship but there is a catch - that is true if you are the only one connecting to the Internet through cable. You share the cable with others in your neighborhood. If there are 100 citizen on the Internet on your single cable line, then the speed gets divided into 100. If there are 1,000 citizen on line, then it gets chopped by 1,000. They don't tell you that when they setup your cable but you find it out soon enough.

The effect - there were quite a few evenings when we had to sit before our computers watching "paint dry." The relationship speed at times slowed down to such a crawl (especially on weekend evenings) that you couldn't tell whether we were using a cable or the good old 56K modem.

Now, after a year of procrastination and hesitation, we signed up with a fiber optic service for our Tv, Internet as well as the phones, for pretty much the same monthly price we were paying to cable plus phone service. And the installation is free on top.

We now not only have the same phone service and approximately 200 working channels (with regular package) but also great and all the time fast Internet connection. To get more than this you need to have your own T-1 line at about ,500 a month.

I implied I didn't watch much Tv to start with but I have to confess - now that we have entrance to all these amazingly high-quality channels that I didn't even know exist, I noticed I started to watch Tv more than before. Not good for my reading and movie watching habits but very educational all the same.

If you are a movie or a Tv fan and you like your Internet relationship fast and trustworthy 24x7, go with fiber optic -- if it is available in your area.
