Ef S Lenses
Canon EF-s lenses…are these the only types of lenses for use on say a 40D camera?

I’m a bit confused…lets say I have older Canon EF lenses…. NOT the newer EF-S lenses…will my older lenses work on say a Canon 40D camera, or do you need to exclusively buy and use the EF-s lenses ???

Your 40D will take EF and EF-s lenses. As well as any third party “EOS” or “Canon Autofocus” lenses.

Canon EF 70-300 mm and special gyro

It is a fact that any type of disturbance that can happen to any camera stabilizer lens can have permanent effects on the images were taken and will be taken. To ensure that this situation is prevented from occurring, the switch manufacturers installed Canon's image stabilization that photographers can easily access. These switches have been deliberately constructed so image completely avoid unwanted changes.

However, all these switches Canon cameras listed. In fact, based on the ultimate guide to digital camera you can buy today on the market, Canon EF 70-300 mm is one of the few camera lenses with these switches.

Its image stabilizer is your third generation, and has greatly contributed to the overall design of the target which is actually mostly flexible. Photographers have the goal with both hands when the object is about 300 mm distance, with a shutter speed High 1 / 45. Although it may seem relatively easy, the operation of such fact can reap good results from images the photographer is set to 1 / Rule of focal length.

For those who do not know, the Canon EF 70-300 mm can actually take pictures with a speed shutter 1 / 5 or ¼, all within a distance of 70 mm. On the other hand, it can take pictures with a shutter speed high speed 1 / 25 if the object in focus is 300 mm so far.

Canon has firmly said that the main reason why many photographers today decide to buy your own Canon EF 70-300 mm lens is due to the presence of gyro. These sensors are responsible for detecting unnecessary vibration may somehow affect the whole image. No matter how subtle movement is unnecessary, the gyro can detect and act upon it to ensure a right angle is held with the optical axis of the lens.

To date, Canon EF 70-300 mm lens is considered as the unit The most popular used by photographers today not only as regards the Canon lenses, but all camera lenses in general. In fact Canon EF 70-300 mm lens is a revolutionary product when it comes to features special applications such as image stabilization. This objective of the USM is loved by photographers because of its provision of image quality with an affordable price, the target size smaller, light, and the range of focal lengths.

Do older ef lenses still work with ef-s bodies? How do they match up to newer lenses?

I am really finding some great deals on old lenses that were made for film cameras, i was wanting to know if these lenses will be sufficient to take great pics on my rebel t1i?
Thanks, i really appreciate your answers. But could you tell me how old lenses compare to the ef-s line? I mean, are there any significant difference that would make me want to pay and extra hundred or two dollars for these newer models?

Simple way to tell if a lens will work with a particular body:

Take your lens off & look at the mount on the body. The Rebel will have a red dot (around 12 O’clock) and a white square (around 2 O’clock). Now look at your lens; the 18-55 (all EF-S lenses) has a white square. Old AF film lenses (EF) have a red dot on the base.

Your camera can take any AF lens that have the same mark on the body. So all AF Canon lenses fit the Rebel, but only red dot lenses fit film & full-size sensor cameras like the 5D.

Update: Old lenses (as long as they’re EF/EF-S) aren’t necessarily any worse than their newer replacements. The only real problem might be that there are no parts to repair some of them if they break. Many newer versions now come with Image Stabilization and that can improve your hand-held pictures. Of course L-lenses are fantastic, but they’re bigger & very expensive. EF-S lenses only exist in the wide-angle zooms (usually starting at 18 or wider) and there really aren’t any old lenses to compare them to.
