Handling Precautions

Do not press hard on an LCD display or subject it to impacts, as this can cause display flaws and damage.

If an LCD display becomes soiled, clean it with a commercially available blower brush, or wipe it with a soft cloth, taking care not to scratch the screen. If an LCD display becomes extremely soiled, consult your nearest Canon dealer.

By their nature, LCD displays react more slowly at low temperatures, and may appear dark at high temperatures. The display will return to normal at room temperature.

Lithium Battery for the Date and Time

Store lithium batteries out of reach of small children. The chemicals in these batteries are very dangerous if the battery is accidentally swallowed. If this happens, seek medical attention at once.

Do not use metal instruments such as pliers to hold the battery, or you could cause a short circuit.

Do not disassemble or heat the battery, or you could rupture it.

CF Card

The CF card is a precision device. Do not drop CF cards or expose them to vibrations. Doing so could lose the images recorded on them.

Do not store or use CF cards near objects that generate magnetic fields, such as TVs, speakers, or magnets, or in locations affected by static electricity. Doing so could lose the images recorded on the CF card.

Do not place CF cards in direct sunlight or close to heating appliances. Doing so can distort the cards and make them unusable.

Do not spill liquids onto CF cards.

Always store your CF cards in a case or cabinet to protect the data stored on them.

Non-Canon CF cards may not be able to record and playback images. If this happens, use a CF card made by Canon.

Do not bend CF cards, or subject them to strong impacts.

Do not store CF cards in hot, dusty, or humid locations, or in locations exposed to static electricity or magnetic fields.

Lens Electrical Contacts

Contacts

After detaching the lens from the camera, attach the lens caps or put down the lens with the rear end up to avoid scratching the lens surface and electrical contacts.

300D specifications

The Canon EOS 350D, 300D, and 400D are pivotal models in the history of Canon's digital SLRs, each contributing significantly to the popularization of DSLR technology among enthusiasts and professionals.

The Canon EOS 300D, introduced in 2003, marked a turning point for digital photography. It was Canon's first entry-level DSLR and brought professional-quality features to a wider audience. It features an 18-megapixel APS-C sensor, capturing images at a maximum resolution of 3072 x 2048 pixels. One of its defining characteristics was the inclusion of an 8-megapixel sensor, which was revolutionary at the time, allowing photographers to produce detailed images. The camera also provided a robust build and a user-friendly interface, making it accessible to beginners.

In 2005, Canon released the EOS 350D, building upon the 300D's foundation. The 350D refined the design with a smaller and lighter body, while also bumping up the resolution to 8 megapixels. It introduced a 2-inch LCD screen with a sharper display, enhancing usability. The camera also incorporated a more advanced DIGIC II image processor, improving overall performance, including faster autofocus and better noise control at higher ISO settings. The 350D supported a range of lenses, further expanding creative possibilities for users.

The Canon EOS 400D, launched in 2006, pushed the envelope further. With a resolution of 10 megapixels, it offered even more detail in images. The 400D introduced a newly designed dust reduction system, effectively combating sensor dust—a common issue for DSLRs. The 2.5-inch LCD screen was larger and featured a better viewing angle, allowing for more comfortable composing and reviewing of shots. This model was also equipped with the DIGIC III processor, which improved shooting speed and image quality, particularly in challenging lighting conditions.

All three models share a commitment to durability, usability, and performance, making them ideal choices for budding photographers. Their compatibility with Canon's extensive EF lens lineup ensures that users have access to a broad range of focal lengths and creative options.

In summary, the Canon EOS 300D, 350D, and 400D each played a significant role in the evolution of digital photography, providing key technologies and features that appeal to both novice and seasoned photographers alike. Their legacy continues to influence Canon's current offerings in the DSLR market.
