why do we need prime lens?

Nowadays, I see more and more good zoom lens with relatively larger aperture number (i.e.2.8) and they all produce beautiful pictures. But why on the earth , lens makers still want to make expensive prime lens ( i.e. Canon EF 85mm f/1.2). optically speaking, they do not have huge differences. even in low light condition. There are very few cases you do need larger f number but this does not give any reasons for high price tag. any other reasons?????

It's a question of what suits the user.

I have zooms and primes in my collection, zooms for maximum flexibility, primes for when I have a subject in mind and know my approach.

My cheapest lens is Canons 50mm f1.8, it weighs nothing on the camera, keeps it compact and delivers great results. I have a 50-500 Bigma, so if I know I won't be zooming beyond 50 I take the 50 f1.8.

I never really have to consider using a tripod with the 50 f1.8, I know it's a bit sloppy wide open so I stop down to f2.8 and it's great. If an a f2.8 zoom was my starting point then I'd want to be at f4 or f5.6 to get the best out of the it.

I have a 200 f2.8 L II. Pretty compact, excellent image quality and superlative AF speed in Ai Servo centre point.

It has no zoom, this may make it less flexible, for me it makes it faster to use, one less thing to worry about. Sure it doesn't suit every application, but for motor-racing it's perfect for my needs. I find my subject, track it for a couple of seconds then shoot away. Never fails.

A 70-200 f2.8 L would be nice, but bigger, heavier, more expensive and not quite as terrifically sharp.

When it comes to super expensive lenses such as the 50mm f1.2 etc, I think a lot of it is brinkmanship by canon, how far can they push the limits. Of course without such terrific lenses we may not have seen very useful innovations like one touch AF, or USM, or ring motors.

The f1.2 is pretty horrible to use wide open, what looks great in the viewfinder can be waaaay soft when you get back to your PC, the main benefit of the ultra fast max aperture is the extra speed it brings to the AF system (more light, more reliable, faster AF) and that when you stop down to f2 the lens becomes very useable.

Obviously the economics of scale come into play, these lenses have a high R&D cost and won't shift as many units as the 50 f1.8 for example,
so they become more expensive per unit.

For certain applications primes seriously outperform zooms. If you want decent macro pics, you want a prime macro lens (one notable exception is the canon MPE 65mm, which has a 5x scale factor: not strictly a zoom in the conventional sense) If you want tilt shift, you want a prime lens.

Some of canons primes aren't all that expensive, bargains such as the 28mm f2.8 (good build, good images, nice & compact, good landscaper on FF, good 'standard' on a cropped sensor, cheap) the 35 f2, even the more esoteric 135 f2.8 SF, all have a useful life in the digital age.

Ultimately the great thing about an SLR system is it's versatility. It's all about choice. Canon cater for this.

There will always be camera club bores who want the best kit in their club (You know the type "Oh you can't take decent pictures with a...") forget them, buy whats right for you and your budget and get out there and take some pictures.

Don't overlook canons cheaper primes too!
