    Canon EOS SLR system NEWBIE guide.
    ________________________________________

    Since there are so many people asking newbie questions about the Canon EOS SLR system, I''ll thought I just post a quick summary here. Help me spot any mistakes if any.

    Newbie guide to Canon EOS SLR system

    What camera models are there in the Canon EOS SLR system currently?

    The approximate prices you can buy the (1st or 2nd hand) camera in that class is stated in brackets.

    For Film Camera,

    Consumer Class ($300-$700)

    EOS 66
    EOS 300v
    EOS 3000v
    EOS 300

    Prosumer Class ($500-$800)

    EOS 33/30

    Professional Class ($1500-$3500)

    EOS 1v
    EOS 3

    For Digital Camera,

    Consumer Class ($1500-$2000)

    EOS 300D (Package comes with 18-55 kit lens, but can also buy without lens)

    Prosumer Class ($1200-$2700)

    EOS D30/D60/10D

    Professional Class ($6000-$13000)

    EOS 1D
    EOS 1Ds

    Which of the above camera suits me?

    1) Choose Digital or Film. Maybe might own both in the future but choose one for a start.

    Shall I go Digital or Film?

    There is extremely long debate on this topic on the Internet and you can read until you grow old.

    Main points though.

    Digital advantages

    - Instant review after taking the pictures
    - No incremental cost of film
    - No need to have partnership with a lab to develop photos.
    - Easier learning curve because of the instant review ( highly subjective )

    Digital disadvantages

    - High initial cost of camera bodies
    - Need to process images on the computer to make it look good. ( Not as idiot-proof as to send to the lab to do it)
    - Dust that gets on sensor is a pain to clean.
    - Camera bodies depreciate in value quickly
    - Batteries do not last very long. ( need to charge often )

    Film advantages

    - Wide variety of film choices on the market to try
    - Easy workflow. Take pictures and send the film to the lab. And you are done.
    - Do not require extensive knowledge on computers.
    - Camera bodies do not depreciate in value quickly
    - Batteries last loooooonger.

    Film disadvantages

    - High cost of film and development services. ( An issue if you take pictures very often )
    - Dust issues when scanning negatives or slides.
    - Need to change film every 36/24 frames!

    Conclusion on the film vs digital debate in my humble opinion.

    a) Go film
    - if you do not take pictures very often to justify the high cost of digital slrs.
    - if you are not proficient in computers

    b) Go digital
    - if you take pictures very often. ( make sure you have the time to do so )
    - if you are proficient in computers

    2) Budget. Look at the prices in brackets beside the class of camera to know what you can afford. If the prices make your eyebrow raised, move down the class or choose film instead of digital.

    Most people start in the consumer class although some people prefer to jump straight to the prosumer class.

    I would recommend starting in the consumer class if you have no experience with SLRs to get an idea of what you get youself into. Move up the classes as you get more experienced. The last thing you want to do is to buy an expensive piece of equipment and you have no clue on how to use it.


    3) Needs/Wants

    SLRs generally are big and heavy compared to the small compact digital cameras. Therefore, if you want a small camera, please look elsewhere and not at the Canon EOS system.

    The consumer class SLRs are the lightest and are a good starting point for newbies to SLR system. Do not buy a professional class camera as the first camera.

    What lens to get?

    Ahh... Here we come to the most controversial part.

    Canon EOS system uses the EF mount. There are many lenses which supports the EF mount including those from Canon (obviously), Sigma, Tamron and Tokina etc.

    Make sure when you buy 3rd party lenses, the mount is canon mount to ensure that it works on your camera. The safest way is to bring your own camera down to test the lens before purchasing.

    Newbie recommendation in my humble opinion.

    The following lenses make a good starting point.

    General purpose lens with a good decent range.

    Canon EF 28-105mm f/3.5-4.5 II USM ($300-$550)

    Canon EF 28-135mm f/3.5-5.6 IS USM ($600-$850)

    Canon EF 24-85mm f/3.5-4.5 USM ($450-$600)

    Telephoto zoom ( long range )

    Canon EF 75-300mm f/4-5.6 III USM ($150-$350)

    Good and cheap prime lens for low light.

    Canon EF 50mm f/1.8 II ($100-$140)

    So,

    Get a general purpose lens in your budget. I recommended only Canon lenses here but do try out the 3rd party ones too. Ask around the people here for more reviews.

    The rest are optional. Go slow. Slowly discover what kind of pictures you like to take and you will automatically know which lenses to get. Do not make the mistake of buying too many lenses at once. One at time is usually more than sufficient.

    Hey, where are the L lenses?

    Hahaha.. do not get them if you are a newbie. Unless of course, the prices do not hurt you at all. The L lenses are the luxury range of lenses from Canon which are good but cost quite a bit of money.

    What is USM at the end of the lenses description?

    USM is Ultrasonic Motor. Canon lenses equipped with USM generally has silent and super-fast autofocus performance. The motor draws minimal power so the camera batteries last longer. There are two types of USM.

    Ring-type USM-equipped lenses, found in large aperture and super telephoto designs, ( more expensive Canon lenses ) allow manual focusing without switching out of the auto mode.

    Micro USM designs bring the performance benefits of Canon''s USM technology to the more affordable EF lenses but does not offer the full-time manual focusing.

    In conclusion, USM is a pretty cool Canon technology to have in your lenses even if you do not understand what it is all about. It''s one of the key advantages of the Canon EOS SLR system. Try to get USM lenses if you can afford the premium price.

    What is IS at the end of the lenses description?

    Canon has developed a series of truly unique lenses equipped with an Image Stabilizer (IS) function that let you capture photos that would otherwise be blurred due to camera movement, greatly expanding the range of handheld-camera photography.

    Is IS necessary?

    No. IS is useful but not absolutely necessary. The IS lenses are rather expensive and should be only bought if you can appreciate the difference it makes to your photography.

    What other accessories to get?

    Millions. Trillions. The joy of photography is that you can''t own everything until maybe you buy a camera shop.

    Cable releases.
    Flashes.
    Tripods.
    Monopods.
    Filters.
    Straps.
    etc.
