canon len

mucc1928

Hello I have a canon EOS Rebel XS.  It's a beginner camera, and it's so light I could use it for backpacking.

However, the 18-55mm len (F3.6 to F29), which is like a wide angle, is good enough for scenary, but not good enouhg for portrait.  For example, i cannot create the blurring background unless I use macro.   I know there is a portrait len, but I don't want to create so much while travelling.

Therefore, is there any len you can recommend, which is good for scenary and portrait at the same time?

Thank you.

To 嘉嘉 , yes, for scenary, i don't need much depth.  But for portrait(human), I need to have a len that has bigger depth.  My F3.6 is not enought o blur backgorund.  And I just want 1 len to go travelling.

To Catpiano, so 50mm 1.8, but it is even smaller than mine, which is 18-55mm.  So the smaller the number, the greater the depth?

Is this the rigth one I should get?  Mm...the terms are so techincal here.

My budget is around $150, first or second hand

Thank you for all the reply here.

I am looking into this: EF F1.8

1) 1.8 is the apenture.  but where do you find the information for the depth?
2) Also, for this kind of len, it is hard to picture things far away, like scenary, right?

How about this one?  EF 55-200mm F/4.5-5

3) Does it mean it is F1.4?  So that's why it is more expensive?  
4) Regarding about the mm part, that is the focal length.  Is that the same as depth?

So there is no way 一鏡走天涯?

Thank you for the kind explanations here! Catpiano and SiuBLoDau!  i would need sometimnes to digust the information here.

I want to make the right choice....the reason is...i am not going to keep this beginner camera long.   when i upgrade, I would go for a higher budget or different brand.  Therefore, i don't want to invest too much on this body.   Well, seems like $200-300 is a must for brand new....and around $150-200 for used.

once again, thank you!
