從ebay上面標來的一只手動老鏡頭

不知道版上大家對這鏡頭感覺意見如何

我還看見一只SMC Pentax-M 1:1.2 50mm 鏡頭

到最後幾乎是美金380元成交

下圖為測試結果

Hi

I have got M50/1.7 myself.  It is a very sharp lens, sharper than the 1.4 version when used wide open.  I have also got K55/1.8 and I believe the M50/1.7 is again sharper wide open.  When all the 50mm lenses are stopped down to f2.8 or smaller, they perform quite similarly.  

Regard 50/1.2, US$380 is actually cheaper than what I have heard.  I have heard that some ebay auction of 50/1.2 have gone more than US$500!!

cheers
Kenny

Hi Kenny,

Thanks for the update. I was thinking about bidding on the 1.2 but not sure if the cost for that lens is justified for the money.


Not sure how good the picture will turn out to be if I really do own the 1.2, but as an amateur, I am sure it won't do much good for me.

I took a few pictures with this lens today, it is amazingly sharp even when I open it up on 1.7. I think it is a lot sharper then the FA 50mm 1.4 I have.

But manual focusing is something I need to practice more..

Do you have any pictures you can share with me by using this lens?

Thanks

Frank

我也有M50/f1.7
鏡身很有金屬質感
拍出來的畫質很不錯 至少我自己是這樣覺得 哈哈

缺點是若接在數位機上,在室內會退無可退,室外會好一點

底下照片是當初剛拿到鏡頭時,還不太會手動對焦,誤按快門的結果

1. 光圈F1.7時,中央解析度算中等,但是四周畫質較差,整個畫面的對比度略為不
   足,也就是黑白不夠分明.其實還是比不上德鏡

2. 光圈調整到F3.2以上,整體畫質趨於一致,對比明顯拉升,細節完全顯現,描寫力
   超強

3. 無限遠對焦,遠處的人或物件仍可辨視出細節,令人讚嘆老鏡的用料扎實

4. 對焦環行程長,轉動的手感緊實而不澀,方便手動對焦.搭配微稜裂像對焦屏後,
   好比腳底板被點上三顆痣以後的孫悟空,完全解放,這時才明白手動鏡這麼好
   玩!
