今回補上兩支鏡頭的200mm成像測試,為了測試的準確性,大家都是手動對焦(Liveview 放大),升起反光板,使用腳架,快門線拍攝。測試相機為Canon 5DsR , ISO 100的情況下進行測試。

200mm中央成像方面,兩支鏡頭差不多是同等質素,在五千萬像數的5DsR下,100%放大下,都有出色的表現。

其次是邊緣成像

而200mm邊緣,Tamron SP 70-200mm f/2.8 Di VC USD G2 比起 Canon EF 70-200mm f/2.8L IS II USM 邊緣成像稍為實結,但差距不大。

最後是耀光測試

200mm

在70mm焦距下,Tamron SP 70-200mm f/2.8 Di VC USD G2幾乎看不到耀光,而135mm則出現極輕微的耀光,而最後的200mm才出現較明顯的耀光。

而Canon EF 70-200mm f/2.8L IS II USM,在各焦段下耀光都比較明顯,相信Tamron SP 70-200mm f/2.8 Di VC USD G2 使用的eBAND納米鍍膜,下了一番苦工。
