I wanna ask which len is preferred???

1. SIGMA 70-300mm F4-5.6 APO DG MACRO
2. Canon EF-S 55-200mm F4-5.6 IS

As limited money I have, I wanna ask which len should I purchase?? I have no idea...........I asked before, SIGMA 70-300mm F4-5.6 APO DG MACRO cost about $1500 and Canon EF-S 55-200mm F4-5.6 IS now cost about $1750. Which one is better?????plz help and leave some comments, many thanks!!!

兩支如果要比既話55-250 IS就係長焦方面因為有防手震有d優勢,另外如果係用kit鏡就會配合到焦段,但係相對黎講,sigma個支就可以用返係FF機,同埋有最大1:2既放大率,要黎玩下marco都唔錯~

may I ask what is"FF機", "最大1:2既放大率" and what is the "marco" mean?? thanks for your answer.

FF機~即係Full film格式,相比起35mm菲琳,其實大部份DSLR既感光原件都係比咬細,只有某d高階型號如Canon既5d系,1Ds系,nikon既D700同D3系,仲有sony既a900既感光原件係等於35mm菲琳既大少(36mmx24mm)而呢類機就係FF機啦
放大率就係指比如一件物件係長2cm,1:1放大率就係投影係感光原件時都係有2cm呢個長度,如果係1:2既話就投影係1cm,越大既比率即係可以睇得越細緻
marco即係微距,DC既微距係指可以好接近去影,但係DSLR就係指剛剛所講既放大率,一般黎講1:3.x已經可以叫做有微距功能,但實制要叫做微距鏡就通常都要有1:1既放大率
呢d都係我個人既知識,如果有錯請各位師兄指導
