即使有轉接環,可能會有鏡後距的問題,無限遠無法對焦。

Y拍上有一個幫人改鏡頭的賣家,小弟也留言向他請教這個問題,得到以下的回答:

"Leica M39鏡只有135mm以上焦段才可以改..."

供大家參考囉!

前蘇聯有出for SLR的M39
接還都一樣, 但有分SLR和RF的不同

曾經聽過日本有出轉接環的
但可遇不可求
再說就算接上去也只能當微距鏡而已

通常所見的M39是萊卡鏡頭
這就算加了轉接環也沒用

少數蘇聯單眼鏡頭
以及歐洲電影鏡頭是M39
這就能用轉接環套到M42上

這邊有網友訂做M39-M42接環

135以上可以改是因為長鏡後面距離感光面比較長,可以有車短的空間。

I think you guys need to start studying better. FOA, don't just assume you can take any lens and put them on any camera. After all, they were designed for different format and different system / coverage / register.

As for 39mm screw mount. First and foremost, the M39 means Metric in the M. Leica screw mount do use 39mm thread but its not metric as its pitch is not ! And that is why it should be referred to as LTM ( Leica thread mount ) or L39 or Leica Screw Mount.

The M39 is used in Zenit SLR system that is registered 45.3mm , while M42 is 45.5 mm register. A simple thread extender 39 to 42 at 1mm pitch is easily obtained and can thus put those M39 lens onto M42 mount but because the M42 mount is 0.2mm deeper than the Zenit register, all M39 Lens would not focus to infinity ( despite what the myth says ). This 0.2 mm is of course minimal for those using long focal ( say the 200mm Teleair or the 300mm Tiar ) but for anything shorter it can be discerned that the lens will not and do not focus to infinity. At shorter focal length is this is of course more prominent and you will only be able to focus to a close up / portrait range at most depending on the lens.

Now unless one already got a stash of these M39 Lens for Zenit SLR. I simply do not see why one should go to the trouble to do that since all known Zenit M39 SLR lens had also been produced in M42 moutn also ( except the rare Ind-22 )

My take would be, go get the M42 version instead :rolleyes:;):fire
