chan hing, 如果50 lux 尼講，V1, V2 好相似，不過V2 coating 有吾同，全開會sharp D.....跟住到Pre A，Pre A 色水更深潤，反差比V2 更高，價錢 (黑色計)，比V2 貴D。跟住就輪到 50lux ASPH，即係現行版 (有錯請更正)

factotum

v2 最近對焦距離1米，pre-a 0.7

個網好正，多謝ghostching解答。散景pre a好的定asph好的?

havn't tried pre a but i know for a fact that the asph is one of the best prime made, optical wise. I find it has perfect bokeh, abit too perfect.

散景尼個問題，就各花入各眼喇，如果兩支揀，我自己就like Pre A 多D，冇貢sharp..

Oops, howcome my whole paragraph is gone!

V1 is basically similar to summarit 50 1.5 w/  larger diameter (that's why the aperture is 1.4). V.2 has a redesigned optical formula. Sharpness and peripheral image quality improved. You can tell from the rear element design, v.2 is so different from v.1.

In terms of barrel material, bottom ring of version 1 and early v.2 (~1845xxx) are made of brass, other parts are made of aluminium

For late version 2 (silver chrome version) all are made of aluminium.

嘩，原來有咁多分別。其實我問得唔好，我想知個影出黎個感覺多的，上flickr同老花好似好少資料咁

其實v1咁多年，點睇支鏡有無問題?有塵有箘有hairline我都明，咁咩係haze?

LanLan

I have tried v.1 and v.2 only.

It seems to me v. 1 邊緣失光比較明顯！v.2 has a better overall sharpness, including peripheral areas.
In terms of color rendition, v.2 is richer in color and have slightly higher contrast than v.1.
You may try to search summarit 50 1.5 to get a feeling on how the pics look like. This should give you better feeling on how v.1 perform.

Since v.1 uses a monolayer coating, similar to summarit and early summicron (taking about rigid v.1) , the middle element group can easliy has coating peel off (especially when trying to remove haze).

To me, it's hard to describe haze in word, it would be great if there's other ching can desceibe w/ sample pictuures haha

basschan

哦，明白左好多啦。唔該晒咁多位ching。
我想問邊度有多的pre a嘅相?

basschan

我係http://www.kenrockwell.com/leica/50mm-f14.htm睇左好耐....
其實的CHING講o既pre A係唔係就係講1992--2004出個支V3?

leinex

之前KFC有ching話pre-a好易有haze(定離膠),仲要係冇得到救果隻,所以都唔敢買呢支
有冇ching confirm到?

PRE-A 表現幾好啊，F1.4 SHARPNESS 已叫做可以接受， 去到F1.7-F2 已好SHARP。本打算換V2，但O岩睇完佢影O既EKTAR ，又唔捨得了!!!!!!!!

V1 is soft and with circular bokeh... very similar to Noctilux 1.2.  Actually, it's optic design and behaviour is a little similar to Summarit 1.5, Nokton 1.5 etc.

V2 is more modern lens design and optically more perfect. Pics are lovely.. many people's favourite.

Pre A is same optical formula with V2 but can focus down to 0.7M. Image is more saturated, contrast a little higher.  In general, a more modern rendering.

ASPH is as close to perfect as one can imagine when it first introduced. Sharp, contrast, saturated etc. A little harsh if you are used to old lens rendering.

I have high hope of the next version. Because Leica's recent lens (e.g. 11663) are just so lovely! Sharp but not harsh! High contrast but still look so real!

真係好頭痛
依家我諗緊summicon 50mm v3同summilux v2 pre a
summicon有我想要個mood，但係好似1.4大的好的。
如果諗summilux v3 pre a又唔知點簡好，又聽的人講pre a易有haze離膠，
v2一米又好似遠左少少但係價又平返的
