Re: Supplied WITH the camera, they do...

It's interesting that so many people are giving you reasons why "older cameras lenses have faster F-stops" ... when they don't.

Now that modestly priced zooms are supplied as kit lenses, with the camera, they do have very much smaller apertures (f/3.5) than the typical single focal length lenses supplied with cameras 20 years ago (f/1.8).

That's true ... and since the high ISO capabilities of todays cameras let people shoot at f/5.6 where they'd previously need a faster lens with "Gold 400" (never mind slower slide films) it could be that fewer people feel the need to buy fast lenses.  But they're there.
