i found this great comparison.. but canon lens though..
http://www.shuttertalk.com/forums/viewtopic.php?id=3532

but atleast can see the prime sharpness..
i would really think 55-200 have better result than 18-55..

lwliam : Your wish is my command. Here's a few snaps from a 50mm lens on a full frame camera:

wah very sharp.. got toll some more.. haha..

wa number 5 bokeh very nice...oh yea..with 50mm prime the min focusing distance is much nearer as well compared to 50mm on 18-55. =)

Kul | Mo0 : ya i going GT but all is japan lui pic you want to see hahaha! i 2 day at there come back no time to upload leh later on lah haha.
mastering89 : I dun have G pic lah

erm how far the distance?
as u know some 'rumah pengantin' very cramped..

Waitt. This is poison for prime or FF ? Kill Poison two forumers with one post style eh.

more like shoot 2 ppls with 1 bullet..

Naruto : No poison lar.... it's just to show you how a 50mm looks like on a FF cam and how much you can do with it. All poison are self poison! Hehehehehe... No one can poison you if you refused to be poisoned.

See my gear list - you can count the no.of lenses I have with one hand and still have plenty to spare!

at 50mm,

for the prime, you can go as close as 30cm(or less?) if not mistaken to the subject to take the picture. as shown as in shootkk's 5th pic. the girl's face + upper body can fill the whole frame(without cropping the pic la of course).

for zoom lens u may need to stand at least 50cm to 1m away from the subject to get the shot...hence u will get a less tighter shot..

sifus here pelase correct me if i am wrong.

50mm can go infinity or limited to certain distance..
or maybe after certain range cannot focus edy?

congratz uzu. eh, u still owe me sthg rite?

1:1 Magnification is true 1 to 1 ratio right? What is 1:2 ? From my understanding 1:2 is not equal to 2:1 right?

^uz_naruto AFAIK if 1 to 1 its not magnification..
(:
2:1 is...

strobist spam, C&C please

So what is 1:2 ? half of the size?

should be. since 1:1 means its life-size.. then 2:1 is magnification twice the size of the thing u photograph.

Theres no such thing as lens cannot focus to infinity.. Unless its spoilt or u put a close up filter in front of it.

lwliam : Who says no such thing? Zeiss also will happen le. ):

thanks
