It depends on the size of the ccd / cmos 'chelle. If this device is as small as on the Sony F828 for example, you'll need that 11 mm or even less (i think, the lens on the Sony starts with 7.5 mm to achieve cropped 28 and reaches 200 with just 50). On the 300D 18mm would work as 28 mm on your analog Cam. Thank god i don't need that ... About that digilens-hype .. i just think this is pure marketing. An analog film has (depending on what film u use) up to 25 Megapixels (equivalent) so why should it be necessary to use better lenses to provide light for - let's say 6 Megapixel? Of course, if you are using (simply said) an analog lens on a digital cam, you'll just use the inner part of the lens .. but for the lower resolution this doesn't matter at all. In fact, you'll lose problems with vignetting(?) and use that "sweet spot" as Donald stated .. but what should an even better lens be good for on a digital cam with a sensor that can't use that additional resolution? To me, this looks like the following: through the smaller size of the sensor, they can produce that lenses smaller (in diameter at first) and therefor cheaper. But that's not what the SLR-customer wants to hear so they sell it as "specifically designed" for the same money as analog thus making more profit and of course, people feel better when buying those "special" thingies. That's right what canon admits to have done on the kit-lens. But i may very well be wrong on that ... let's see what that article of you says and what Donald has to offer on that. Sorry .. if this sounds rude, it's just my inability with your language and not intended! @Identguy: have fun with your 300D and be welcome ... if there are questions about your new toy, there are a lot of others here gladly helping! Got yourself a great cam! Tom
