It’s always a tough choice between wide angle and not so wide angle lenses. Wide angle lenses are very good to capture the entire scene, but you are going to lose some details since you are cramming more viewing angles into the same size image sensor. It also means you need to deal with losing sharpness around the corners. Sure! there will always be an ultimate lens does it all! But my limited depth of pocket probably just isn’t going to cut it. Unless someone sponsor me of course 🙂
Anyway! Back to the topic..
These tests are trying to find the balance of color and sharpness on both lenses. I have to say Pentax came a long way to make DA line-up appealing. Lens construction fits the bill, image sharpness and color rendering are not bad either! Although I prefer FA series for the manual focus handling and sharpness, but You can see the color differences between them.
