Specific lenses for digital camera

yb98 · 26th of May 2004 (Wed)

Do you think that a lens which has been made specifically for a digital camera (such as 300D or 10D) will be better than it's equivalent 35 mm ? also cheaper ?

If so, do you think canon will make new lenses for their digital cameras ?

I'm looking for a telezoom to use with my 300D and was wondering if I should wait for new lenses made specifically for the 300D or if I can buy one now without having regrets in the near futur.

Yacine.

Maybe you have missed something. Canon made its EF-S lens specifically for the Digital Rebel (300D). It is cheaper and lighter, but probably not as good as ordinary EF lenses.

If you get the EF-S lens, it will work good, but only on that camera. In contrast, if you get any EF lens, it will work good on digital or film cameras, but it will likely cost a bit more.

the 18-55 is not the only digital dedicated lens, sigma has 2 i belive...i dont know what the difference really is though

I'm not sure. Popular Photo claimed that there can be differences - film is receptive to light hitting it at a bigger angle than does a digital sensor. Also, the front of the sensor is more reflective than the front surfact of film and thus can decrease contrast and increase the propensity to show flare. They ran a test in the study, but it really didn't have enough lenses in it to be a conclusive test.

It is possible that Olympus may have fed that point to the PopPhoto writer. They are the most enthusiastic at marketing "digital" lenses.

The only real factor I've seen that sets digital lenses apart from 35-mm lenses is size and price. Less image circle area = less glass = lower cost.

Sensors can be made to work PERFECTLY with ANY 35mm lens-it's just a matter of cost.
Most of it is in the design of very good microlenses over each pixel site

The '35mm full frame' sensor on the 1Ds for example has much more done to it to work with current lenses than the 300D/10D/etc need.Wide angle lenses are especially difficult to adapt the 1Ds sensor to.

Canon's common 1.6 crop sensor is relatively easy to make and works near perfectly with all EOS lenses ever made
