(本貼假設閣下已經對使用手動鏡已有一定經驗, 如想多認識關於鏡頭(光學)的知識, 可以參考下面的連結.)

受惠於可換鏡數碼相機的流行, 再加上無反光鏡可換鏡頭相機(MILC)的出現, 近年越來越多人接觸手動鏡. 現在特此開這一貼, 觀迎各會員主動分享與交流關於手動鏡的主觀或客觀經驗, 亦觀迎提出關於手動鏡的問題(建議先google).

本貼主要圍繞只可手動對焦的鏡頭(不包括如有手動對焦功能的自動鏡(手動改AF鏡除外)), 內容可以包含同自動鏡的比較. 如想單獨討論自動鏡, 可以另行開新貼.

鏡頭有便貴, 但無貴賤. 同一支鏡, 不同的人會有不同睇法. 尊重他人, 尊重自己, 尊重鏡頭, 理性討論.

透過分享, 自己也會學習到更多東西. 謝謝大家參與!


P.S. (To be updated or changed)
1) 如非談及自己親身經驗, 請盡量註明信息來源.
2) 如果貼多張相, 建議先貼去作品藝廊 http://www.hkepc.com/forum/forumdisplay.php?fid=111 , 然將連結貼在些.
3) 如果相分享大圖(散景要大圖先睇得清楚), 可以先Upload上相簿, 再post Link或者BB code. 請留意顯示size不能太大, 最好以1024為上限.
4) 歡迎轉載閣下關於手動鏡的link, 如blog或相簿等.

有兩枝手動鏡
Body: NEX-F3
Super - Takumar 50 mm F 1.4 M 42 Mount
Wesley 33mm f/1.6

暫時黎講
50 .4 影大頭
33 .6 影一大班人半身大合照

心得:

對焦:
初初用好唔慣
之後知道body 有得放大畫面, 鋒值幫助對焦
開始易用
有試過係活動上用
如果幫人影合照
唯有信峰值, 之後再轉少少影多張

景深:
初初入左枝景都係為左大光圈
做到淺景深
影影下先發現
景深同構圖有好大關係
如果張相立體D睇, 構圖係平面上既構圖(如數學上既XY軸)
景深就係張圖既前後距離 (如數學上既Z軸)
所以, 要估計鏡頭同初攝既人距離
之後想影到幾多景深, 就要較返相應既光圈
如 NEX-F3 + 50 焦距 1.4光圈 被攝人在1米距離
景深有 0.02 m (2cm)
如其他條件不變, 只轉左 1.8光圈
景深有0.03 m (3cm)
多左1cm 成張既立體感即刻唔同左

光圈: 日光時間，唔洗開到盡, 1.8-2.8 都夠
晚上, 多數開到盡, 方便手持影
注意: 唔好為左影到散景既大波波而開到盡
決定光圈時記住諗下景深

body: 如果有埋防震就更好, 可惜sony body無

鏡:
50 .8 散景好靚, 人更靚就更好
33 .6 幾滿意散景, 300港幣算抵玩

以上只是個人心得, 如有錯請指出, 我都想學下野

好... 到我
Vivitar macro 55mm f2.8

Vivitar 美國品牌，由猶太移民創立，
有人話係自家設計日本代工 ，亦有人話只係貼牌，
但有唔少型號連生產商都無，所以無從稽考..

鏡頭由 komine (28xxxx)製造，日本"日東光學" 至令仍然生存中。
支鏡表現唔錯，紫邊好少，最大敵人係手震 ，1:1放大手持有難度

My 2 cents :

I have lots of old Nikors (and a Zeiss 85/1.4) ... (I'm an old cake). The followings are what I consider as collectables :

28/F2.8 Ais : There are a few models and only the newer one that would focus down to 0.2M is good
35/F2 Ais : Made in Japan metal body, very sharp with a very flat field that is quite useful for FF bodies
35/F1.4 Ais : Very sharp at F4 to 5.6, color is a bit less "rich" than modern designs
50/F1.8 Ais (MIJ metal body, not "E") : Sharpness is very good even at F2 with a very flat field
105/F2.5 Ais : The portrait lens of the seventies. As sharp as the Zeiss 85/1.4 that I have, with more suitable for male models.

I have played with a 800/5.6 MF, but its just too difficult to focus for my needs.  I don't think you'll have any problem with MF for 50mm or wider if you stepped it down a bit.  For 85/1.4 I usually bracket focusing by shooting a few shoots while turning the focus slightly.

Welcome!

This is a very good conclusion of some classic from Nikon. My friends 105/F2.5 Ais is sharp as hell. The 135/F2.8 Ais is also sharp as hell but it is much less famous than the 105.

您客氣了
我也是沒錢，食樹皮也改不了飲奶食菜
冇錢也有冇錢的玩法，R28/2.8 e48、R50/2 e55加版、R90/2.8這是最便宜的飲奶方法。

Some of the modern designs could be sharper and less affected by flare etc but I found the older ones color and contrast are more pleasing to my eyes.

Every time I go to Tokyo I would spend some time in Map Camera to see if I can find interesting deals - I am sorry to say but I think they are more honest than some shops in Hong Kong!

The 50/1.8 is really a very good lens for everyday use.  Its very compact and delivers excellent results.  Even the later made in China ones are similar in performance (they are less sharp wide open) but considering their cost it should be in every nikonian's bag!

Meyer Oreston 與 「勝利(日)之吻」

網上有不少賣家都將用「勝利(日)之吻」形容Meyer Oreston 50mm F1.8(M42 mount) . 實際上Alfred Eisenstaedt 的「勝利(日)之吻」(V-J Day in Times Square) 攝於1945年8月14日, 當時市面根本未出現M42相機(第一部有售M42相機係1949年發售的Contax S).

解說:
些說法最早可能出於空氣大的 「老鏡轉接大哉問」 .

http://www.sonysdf.com/alpha/vie ... =27933&start=90

以空氣大修養與學識, 相信問題源於資料上的訛誤. 後來Alfred Eisenstaedt的相機在westlicht-auction拍賣, 也印證了原本用的相機是一部Leica IIIa.

imaging-resource的"Kiss in Times Square"報道:
http://www.imaging-resource.com/ ... es-Square-and-Leica

westlicht-auction拍賣 link:
http://www.auction2000.se/auk/w. ... 118_1303&inO=74

雖然Meyer Oreston並不是「勝利(日)之吻」所用的鏡頭, 但無損本鏡的實用性.  這支於1960年左右發售的鏡頭, 屬於本人推薦東德50mm大光圈入門之一, 另一支係CZJ Pancolar 50mm F2.

35mm f2 iv. The first m mount leica I got, not optically perfect but has a charm.

21mm zeiss.  great lens considering the size/price/performance.  Picked this over the leicas for the above reasons.

This is a fine collection! Any experience or photos of the lenses in your collection?

Any lens can be give you fun. Even a DIY pinhole from a lens cap can be a good choice. You will need to give more details: price, focal length, brand/country, bokeh and etc.... Or you can take my advice and buy one of the Germany 50s I have mentioned.

and more 35 f2 iv, it is indeed the best balanced travelling lens.  It is also superb with black and white conversions due to the lower contrast and gives great latitude for post work.

will upload later XD i am hong kong and i can can read Chinese but sometimes lazy to type (weak  on typing Chinese )

the 50 you suggested was SCHNEIDER XENON 50 1.9?
my pancolar does not have good coating and flare a lot in some situation and the material of the glass now become yellow .

this is my nikon 43 - 86 mm version 2 modded with a black sticker (if you want really cool flare and ghosting , go version 1)
and the bokeh ball middle are blocked = looks like mirror lens bokeh
minolta 250mm are too expensive and the way to made this was block the middle of the aperture , this lens have a glass which very near the apertute , also easy to disassemble and reassemble for modding

this one is by china 50 F0.95
really shallow DOF while wide open , the sharpness in middle still good but not that sharp at border

another one while i got this lens from reseller and playing around on the street
this was like 400 iso as i remember .__.

Frank. English is fine as long as you keep it simple.

XENON 50 1.9 is a good lens and I think it will fit your collection. A cheap Helios 44-2 is good if you need the swirl effect.

This is a good idea to make 管氏鏡 from a cheap lens. You can enjoy the bokeh without spent too much,

The Mitakon 0.95 is pretty high CP as a 0.95. They will make more lens in the future and I hope they can make more affordable lens in moderate speed

couldn't see the links but if shooting 0.95 and focus is on the centre, the borders will be soft by nature due to the dof.

here is my f1 at 100%... sharp enough at f1, iso 400, 1/60

作者: inzite    時間: 2014-11-11 00:59



the 50 0.95 you have there is quite good for the value pitted against the leica 50 0.95.  The only downside I've seen so far is the ability to handle direct flare.

yep , it also have kind of internal reflection like the VM 35 1.4 , have a blue / white ring while wide open and point  to the bright light source (vm 35 1.4 are orange and i like that too)

coating was not same level as modern lens , i put on a screw hood on it (orginial hood are so dumb , it will block by any filter , it does have smaller ring than filter , i ve try B&W , HOYA , KENKO and even cheapy GREEN , all of them are bigger than the hood inner circle = never able to install that cheapy plastic hood. i bought a long metal one instead .

this lens is the first lens that too fast in daylight and i need to put a ND8 to use it wide open @_@

my MF lens collection :

zeiss ZF 85mm F1.4 (supreme colour, and sharpness once pass F4)
Voigtlander 40mm F1.4 (work very well on XE1, but corner is not that great on A7r)
Leica R 180mm F4 (bought this by accident, but it's light so it's a back up in my bag)
Leica R 180mm F2.8 (lovely colour, but not my favourite FL)
Leica M Tri-elmar 28-35-50mm F4 (my bread and butter lens, i wish 28mm is sharper tho)
samyang 8mm (my favourite lens when travelling and do star shots)
Lensbaby 50mm F2 (bought it very cheaply, still have no idea how to use it properly. decent sharpness once passed F5.6)

mostly used with X-E1 and A7r.
i also have contax n 24-85mm and nikkor 50mm F1.8 D that i use as MF lens on A7r.

The flare problem is known on this Mitakon lens. The poor internal light baffling you mentioned and the weak coating as well as the complex design.

If you set use custom white balance, you may discover visible color change when you change the aperture(more visible on smaller F value). This is a another major weakness on this lens. However, we cannot ask too much for such price.

interesting, I wonder why.  Maybe someone that has the A7 can say if the wb is usually consistent or not.

作者: anonymoushk    時間: 2014-11-11 07:59



yep , i got sony nex 5 /6/ rx10 and a7r both have same issue

while some color fill up most of the frame , the auto wb will change to another value. after zoom out the wb change again. set it manually wont have this issue
   
this lens wide open does not very sharp while more than a few meters like maybe 5 meters afterwards it does not sharp as closer focus distance

stop down help reduce fog and flare + bring up contrast and sharpness
the lens should perform better if those internal dust cleaned out =[

Many fast lens will have color shift. In this super fast lens, the color shift is more prominent because they focus on make the lens sharp but not to correct the color shift. Similarly, they design this lens to perform better in close distance.

I help my friend bought two Mitakon 85mm lenses. The first one with a small piece of plastic visible inside. The second one have some small dust. I guess they don't assemble the lens in a clean room. Those tiny dust will only impact the contrast if they don't cover a large portion of the lens. Even you clean it, the dust might come back soon because of the poor shielding.

The change of the AWB value is caused by the color shift/change of the lens when focusing/adjusting aperture. The camera will not change the AWB value if there the lighting condition remain constant.

not sure on that, lets wait for him to clarify. he did say "while some color fill up most of the frame , the auto wb will change to another value. after zoom out the wb change again. set it manually wont have this issue"

it would be hard to believe a lens will cause a change in wb just by stopping down the aperture or focusing differently.

yep , the ambient environment and lighting are unchanged but when i fill the frame with specific color stuff it will shift the auto WB ,  custom fix WB setting wont have the shifting issue

e.g.
wide : plastic table with a A4 size piece of wood material on it
tele : fill the frame with the wood

and the auto WB will shifting a lot if i fill it up by different stuff , this does not happen on my canon / nikon DSLR , only on sony mirrorless , the a55 does not have this issue .maybe the light reflected fake the sony too much ?

the extra metering system on SLR seems do their JOB haha

too hard to manual focus on moving object when the focus peaking wont work =[

try hard and need more improvement on 0.95 , one does not simply to handle that shallow DOF

the lens does have some bright , strange bokeh borders while there are some "specific" frequency or wavelength lighting (yellow / orange stuff?)

我講緊的色偏問題(color shift/change)係另一樣野. 換句說話講: 支鏡係唔同光圈有唔同的發色.

師兄你可以試下係同一場景(最好包含唔同顏色的場景):

A)AWB, 影一張 F0.95, 一張F2.8. 後制時兩張RAW的色溫調到一樣比較兩張RAW顏色是否一樣.

B)custom WB, 先Set好一個色溫(如5600K), 影一張 F0.95, 一張F2.8. 直接比較兩張相顏色是否一樣.

This is interesting! I found the test from MX Camera with custom AWB shows there is signification change of color on different aperture... May be I could ask if they have a copy in their showroom for test.

thats looks like the flickering of the light source as they have specific frequency (actually they are flashing but human eye does not able to catch the flash)
shutter speed are too fast @ 1/1000

the actual power of that light source does have peak and Trough

canon 7D mark2 specially add a features that will try to handle this issue
MX Camera are doing the test in wrong way in my opinion LOL~

Yes. You are right. They need to use a slower shutter speed(<1/60s) to do this test although their target is to show the CA.

一般我都用RAW+AWB拍, 反期有需要再較WB. 遲D買張color checker, 有需要時再用color checker set WB.

現家研究緊偏色, 因為有人發覺某D鏡係film度都會出現色偏問題. 原因主要可能係因為光線由空氣進入玻璃時, 不同的入射角會有不同的反射度. 好多大光圈鏡邊位鏡片的弧度大, coating不能完全消除光線的反射, 以致只有一部份光線可以通過, 造成偏色.
