看過兩邊有關TC的文章，剛巧又有兩個TC在手，於是手痕又上天台試試。

Canon 350D + Tamron 200-500mm + Tripod
ISO 800

兩個組合拍六張，然後選最好一張作比較

Comparing the 2 TC, Seems Tamron 1.4X is sharper

同意, 用咗t記嘅TC好過c記 (sharpness方面)

I don't think Tamron is sharper than Canon from this test because the sharpness of shotting Lunar is more dependance on the seeing (steadiness) of atmosphere. So, I suggest you should better to shot some static and nearer target rather than to shot the moon. :)

And, from your photos, it seems a little bit out of focus on the photo taken with Canon TC.:)
