在德國官網上看了APO-Lanthar的鏡頭,它居然說除了接M接環外,接Fuji X mount與Z mount的效果也OK?
請問各位資深大大,有經驗可以分享嗎?
因為先前爬文有看到接E mount與 X mount的表現有些微差異,假如想接在現今無反機身上,哪家的機身可得到的光學效果是比較好的?
>我有作過功課,CMOS的濾鏡厚度,會導致镜頭的色散抑制需要另行特别優化,所以對於玩轉接來說影响真的挺大。
索尼A7R4 1.75mm
佳能 EOS R 1.6mm
松下 S1R 1.45mm
佳能 EOS R6 1.2mm (R5好像也是1.2mm)
尼康 Z(不包括Z5) 1.1mm
所以就我佳能接福倫達的經驗;尼康玩轉接不論福倫達或是萊卡鏡頭,都也是挺優異的;而 且還出了自動轉接環,你如果要玩轉接,不用擔心。我canon系統接這些手動鏡,是為了輕便高畫質,而且我也訂了一顆LEICA 35 APO (但不知道要排幾月、幾年了);這些手動鏡頭真的有別於原廠的發色,而且重量也是輕便,我打算日後有機會出國就帶這些手動鏡,一來高畫質,二來輕巧好攜帶。希望這些回覆對你有參考價值。
另外你提到的FUJI系統,因為他是APSC ,有別於全幅機種,我看滿多網路前輩貼圖,很是優異,可能是CMOS比較小,擷取鏡頭的範圍跟全幅不一樣,這沒什麼高低優劣的,取決於你的習慣而已。當然M鏡接LEICA M機一定是最棒的,因為M機有特別優化處理,只是價格也相當高。我是建議你可以尼康玩看看啦~~~

The performance ranking generally goes something like this in the order of sensor stack thickness plus micro lens optimisation, AA filter, etc.:
Leica M10-R 0.9mm (UV and IR filtration layers have been merged together, so even better than past M cameras)
Leica SL2 1.2mm (same improvements as above)
Nikon Z 1.1mm
Canon R5/R6 (newer) 1.25mm
Sigma fp 1.3mm
Panasonic S 1.45mm
Canon R/RP (older) 1.6mm
Sony 2.0mm (although with the BSI sensors performance has been improved, I also found the original A7S to be the better than the rest so A7SIII might work well)
就我日前所找到的文章,文章出處我也忘了那兒了;還有雖然提到SONY是背照式CMOS感光元件,但目前最高畫素的A7R4厚度也達2.0mm,所以也有網友提到了,如果不改機的前提下,全副應該以尼康最好了,但我覺得canon也不差就是了;但是如果你要轉接比21mm更廣的鏡頭,我就不知道了;畢竟沒玩過的東西,我沒辦法妄下定論。
因為我就是canon R5的持有者,雖然日前也玩過一陣子SONY,但還是偏好佳能機型的操作,所以我作的功課就是找到關於一些討論區,也有國外CANON的玩家分享的經驗,文中也提到在該玩家21mm鏡頭以上的表現都是相當優秀的;當然這也就足夠符合我要採買的方向了,畢竟我常用21mm 28mm …當然leica 或福倫達日後一些apo銘鏡,只會針對這些數位機身校調的更好;不會更差。希望能對你有些許幫助。
目前無改低通濾鏡下,我相信你心目中的尼康會是很好的表現的。
The degradation is most severe with 35mm or wider, still present on 50mm, while my 75mm f/1.4 functioned perfectly with basically everything. For some reason, lenses without an aspheric element seem to perform a bit better. Symmetrical designs like Biogon are the most problematic.
You can find a lot of adapted rangefinder tests with Sony bodies on phillipreeve.net and a few threads here as well:
I suppose I can share my experience of adapting m lens to Canon RF mount camera.
I don’t have the original R, but I do have the R5. It actually surprises me. The adapted m lens (zm 50, zm 35, and even zm 21mm) all performed really well. When I torture test using the 21mm, I don’t even see edge color shift. The resolution is as good if not better than my M240.
I don’t know why to be honest, there is no focal length specific adjustment for R5 like the one on M. The only explanation I can suspect is the new sensor stack filter on R5, which uses some cancellation magic. Canon declare R5 has higher resolution than even their own 5DSr. And this adaptation results may be the side benefits.
Anyways, thought I would share.
