So im guessing 18-55mm lens is what you refer to as a 50mm lens for general shots?
No, 50mm is 50mm, 18-55mm is 18-55mm. Though I admit I am probably wrong in suggesting a 50mm as a starter, youd probably be better off with the 18-55mm as its more versatile, but not as sharp as a 50mm. I just got a 50mm and think its great, the only thing being that the "zoom" is with your feet.
Bare in mind that as the 18-55mm kit lenses have a bad rep and are quite often obtained as a kit, they are extremely common on ebay so you CAN pick up a pristine 18-55 for < £50, the ones Ive seen have gone for £25-£35 lately. you might find it cheaper to get a body+duff lens, and sell the duff lens on, and get a better one, than to get one with a ok lens?
I hadnt mentioned the 350D due to its age, but it certainly was/is a very popular camera.
I understand, it might sell for a lower price because the lens is damaged but the lenses are cheap enough to warrant a lower bid. I was reading earlier the links i posted above, one of those cameras comes with an 18-55mm USM lens which is apparently the type i should be looking for. (Ring ultrasonic (USM) drive.)
