關於 Tokyo Optical Simlar 50/1.5

LanLan

Any Ching has this lens?Did some searching online and found that it has a rather weird optical formula:
1st half Sonnar + 2nd half Guass design


Appreciate if can share photos taken w/ this lens

Also, is there 專用 filter and hood?

Thank you.

Thanks chamm78383 ching for the pictures! As a 50's lens, the sharpness and bokeh are really good

Yes, very pleasing bokeh

第二張d散景就好Sonnar，第一同第三張就好typical電影鏡油畫散景，double gauss功勞。

I have no time no play Topcor lens, if my memory serve me well the filter should be a silver rim Leotax 40.5mm, same with the 50/2 lens, which should not be too difficult to find
Not sure if there is exclusive hood for this lens, but other standard lens has a screw hood
This is my most favorite 50/1.5 lens, to me: Topcor > Canon > Voigtlander > Zeiss > Leica

Yes, it is 40.5mm filter diameter. This lens is really unique compared w/ other 50/1.5 lens

But when I try to use a 40.5mm UV, it seems not correct and a bit bigger than the thread

記憶中佢支鏡坑紋較少，擰一兩圈已經到盡頭

Or maybe try A42 slip-on filter? To be honest, haven't seen 專用 filter and hood for this lens yet.

我得支Topcor-S 50mm f2，不過影出來好立體，我覺得正過Summicron 5cm f2添。原裝Filter同Hood用Leotax，我用舊Kenko RF Hood
