兩支都係好鏡....28mm f/1.8 = $3300, 35mm f/2 = $2000, 即係 $1300 賣 USM, f/1.8 !!

如果計哂 機身用料 及 photo quality...邊支好D???

唔該師兄幫一幫手!!

我用 50D 機身, 現本身有下列鏡頭在一般性用途 :

1) 10-22mm f/3.5 - 4.5

2) 24-105mm f/4

3) SSWIS

4) Sigma 50mm f/1.4 (已賣, 因難捨原廠情意及太重!!)

要買番支定焦大光圈又輕又耐用...作在家中影由初生BB 至 數年成長間之主鏡!!

補充...短時間不升級上FF!!

影BB計，35mm較28mm好。

另外我想問...我可不可以用

1) 一支28mm f/1.8 or 一支35mm f/2

加

2) 一支50mm f/1.4

去代替我支 24-105 f/4L 呢???? 因我已有 10-22 f/3.5 - 4.5 and 70-200 f/4L IS !!!

taxi-driver,
條數唔係你咁計,$1,300買USM和F/1.8,
第一,28MM的WIDE,始終會多過35MM的WIDE.
第二,28MM F/1.8有全時手動對焦,始終比較方便.
第三,28MM的用料,外觀上,始終PRO過35MM.
要TELE,可以用錢買1.4X和2X增距鏡,但就冇鏡可以做增WIDE.
要TELE,冇錢可以行近兩步,但係要WIDE,有時真係褪無可褪.
以年宵為例,28MM,睇到乜就可以影到乜,完全唔使褪.
如果唔夠WIDE,你褪得兩褪,人群就會在你的鏡頭前行來行去,直接影響拍攝的成功率.
再講,28MM F/1.8 USM, 35MM F/2, 50MM F1.4 USM,
24-105L F/4 IS USM和70-200 F/4 IS USM我全部有齊.
你所講想用28MM F/1.8 USM, 35MM F/2, 50MM F1.4 USM,去取代24-105L F/4 IS USM,
其實好難用取代二字,因各有各用途.
一支24-105L F/4 IS USM覆蓋焦段廣,WIDE及TELE亦取其中庸,又有IS,雖然F/4確實係細左少少.
而用多支鏡去取代一支鏡,換鏡換得多,後鏡和CMOS入塵在所難免,結果又係搵自己嚟煩.
除左換鏡換得多,出鏡帶咁多支鏡,其實都幾煩,又阻地方,換鏡又怕入塵又怕跌鏡.
當你試過要孭超過三十磅器材去五天旅行,晚晚對腳酸痛到唔塗安美露都瞓唔著,就知道有幾辛苦.

csmarco,

Very good points, many thanks!! i will consider your advice. why I choose 35mm f/2 rather than 28mm f/1.8 in first, it is because i have 10-22 for wide shooting use...but i will try both lens in show room before make decision.

thank again.
