解像力だけで描写力は測れるものではありませんが、少なくとも全域でのバランスの取れた解像度を見る限り、Tamron AF 17-50mmが一歩抜きん出ているようです。
特に周縁部での解像力低下が少ない点は特筆できます。
コストパフォーマンスの高さは驚異的としか言いようありません。

本レンズが一番強いのは、F5.6ぐらいでしょう。全画角で2000本〜2200本を保っています。

35.224 yen ? wow , it is cheap .

I paid 434 USD for it in April in LA.

In the US, the Tamron is expensive and the Sigma 18-50 is a bit cheaper than the Tamron, but they are still more expensive than their prices in Japan....


Both are sharper than my Canon 17-55IS , also , they are exceptionally compact.

I think the Nikon 17-55 and Canon 17-55IS are too big for D40 , D40x or Canon EF-S mount cameras like 30D and 400D , for which they are designed.

The Tokina is also sharp and built well exceptionally well, but it is very prone to flare and the huge lens is as expensive as its huge size.

So over all the Tamron is the best of all in this category.
