本人用Canon 550D 只有一支18-135mm kit len. 想多買一支實用又唔太貴的多用途鏡, 要求如下:

1. 影人像景深
2. 可微距影生態如蟲, 蝶等
3. 原廠或副廠鏡都可以
4. 防震
5. 價錢實惠

第一, 請師兄推介一下!

Canon EF70-300mm F4-5.6 IS. 畫質可媲美小小白。

Canon 100L?

dickhen兄

Canon EF70-300mm F4-5.6 IS是微距鏡嗎?

[dickchen]

70-300 IS 鏡身有標示為Macro，但最近對焦要1.5M, 放大倍率也不高， 所以macro function只是聊備一格，不過用來遠攝花花蟲蟲還是可以的。

Albert Ching,

>>本人用Canon 550D 只有一支18-135mm kit len. 想"多買一支"實用又唔太貴的多用途鏡
18-135 is ALREADY a 實用又唔太貴的多用途鏡... why need "多買一支"

A lens is designed to do a limited scope of topics, and no lens can be designed with "many functions" and it is 價錢實惠!

If you get a lens with many functions, and is 價錢實惠, then its quality is very very probably similar to your current 18-135! If it is so, then why you buy an additional lens?

I guess that there may be 3 ways that you may consider:
1) Buy an additional 50 1.8 with $700
2) Replace your current one with Canon 15-85
3) Replace your current one with Tamron/Sigma 24-70 2.8

Good luck CHing... Just remind that your current lens can already do all of the things mentioned in your pt #1 to pt #5...

唔該師兄
1. rankelo 兄請問點樣可以用我支18-135mm鏡影人像有景深?
2. 點樣可以用支18-135mm鏡放大影蟲見到佢地細致部份?
3. 如只買支Canon 50/f1.8 加Tamron 90mm/f2.8Macro如何?或單買其中一支?請畀意見
謝謝各位

albert2010 CHing,

Maybe my tone is not good and make you angry. I say sorry first. 多買一支實用又唔太貴的多用途鏡 is really a waste of money if you have 18-135 already.

1) If I have only 18-135, get close to the 人像 and use 135 (tele) end will have the max 景深 for the lens. Of cox, you may think that this is insufficient . Then you may try the 50mm 1.8 again and this is the cheapest solution for this issue

2) Similar to part 1. If you are really very interested in the details of the 蟲, the EF-s 60mm (from 叮噹仔 CHing) or Tamron 90mm/f2.8Macro can help. Personally I never tried these 2 lens and I cannot say anything on this.
One alternatives is that you can buy the Extension Tube for your original 18-135... this is a cheap but poor quality solution. An extension tube will reduce the closest focus distance of all lens but of cox this is just a workaround for poor ppl only

3) Both are ok and worth to buy. I have no comment for this

Hope that it helps

Dear rankelo c-hing,
I must say a million thanks for your advice. Please don't mis-interpret my voice / tone. I was not angry at all but really interested in knowing how to make use of my len 18-135mm to take depth of scene pictures and close-up inserts. I did not know that my len could be so useful until you told me. Thanks again.

I think I will first try 50mm/f1.8 to see how it works.

By the way, is there a big difference between a 對焦Macro and 定焦Macro in terms of price and picture quality? and which focal distance is the best for first time buyer aiming to shoot inserts / flowers?

Thank you again.

樓主, 小小糾正下你地個用詞先,
我諗你指既景深, 係散景(好似濛D既感覺),
果種係叫淺景深既效果, 係MIN, 唔係MAX..

淺景深既技功, 莫過於大光圈及你(A)同目標(B)同背景(C)既距離比例,
圖像化就係 A-----B--------------------------------------------C
咁你用長焦段既效果就係用光學原理拉近左A同B既距離,
再簡單d講, 就係你用長焦段影人, 後面背景遠離你地多d就會有淺景深效果.

定焦macro 同變焦marco個效果真係好唔同!
不過如果你真係好想zoom lens with marco黎用,
你就留意佢既放大倍率+最近對焦距離既配搭,

另外Tamron 支90mm, d色淡過淡奶,
AF慢, 極嘈, 對焦程長, 無全時手動對焦,
所以接近無用.

多數人會叫你買100L, 不過你睇下個價錢,
就知點解我唔建議你買.........


支60M有1:1, 幾sharp,同有USM
60mm影人唔錯, 無IS仍然容易保持安全快門.
可以上showroom試下.

多謝師兄指教！

我打算三支鏡走天崖
18-135 kit len (snapshot 人/景/建築) + 50M/f1.8 (影人)+ 一支微距鏡

請問:

定焦60M影人像應不錯, 但若用來影蟲, 蝶之類又會唔會焦距太短呢？

若我去買支平的50M/f1.8影人, 再買支微距鏡, 主要影下花, 蟲, 蝶之類, 60M夠用嗎？還是要一支長距一點的定焦微距(e.g 85, 90 or 100)比較好呢？

變焦微距是方便可長可短, 同定焦微距比較出黎的較果無甘靚, 真難選

[叮噹仔]

60mm係拎個中間位, 比你兩用,
85~100mm 影人就下下大頭, 如果+埋macro既細緻度, 應該唔會太討好.......
而就算你話100mm都好, 都係唔夠長去影蝶, 影出黎同長焦鏡差唔多,
唔會太有macro既特質,

影虫, 只要佢唔係識跳既, 60mm應該無問題,
當然, 90mm會可能比較好, 因為可以企遠d唔會騷擾到佢.

zoom 同prime marco既分別, 好大部份在於個放大率,
如果影同一隻野,zoom 既, 通常會唔可以影到咁大隻,同無咁細緻!

師兄們
我巳有支18-135mm, 打算平平地買支50mm/f1.8主要影人另加一支實軍惠價(<$3000)的微距鏡影下花蟲蝶
照你意見我係末應該買支定焦90mm微距鏡有1:1放大率?有冇好介紹？我只知人地話tamron 90是代表作.
還是買支Canon 60mm USM Macro?
請賜教
