I've heard a lot of reports from users of the 75 that they are just amazed. Sure, I can see the great pictures people have post online but it's not the same as actually using the lens yourself. The same is said about Sony's new 55/1.8 for the A7 line. On the sharpness scores the lens looks mediocre but people love it. I'm just wondering if any other lenses have had you guys amazed because they're just that good. Does the 45 fit the bill? The 60/2.8? With my list of low-priced lenses I can't really say that I've really been amazed. My favorite lens to use is still the first one I bought: a niffy fifty. Sure, the fisheye is remarkably sharp as is the 30/2.8. But I can't really say I've had and "amazing shooting experience" like people are claming with the 75 or that Sony. Hopefully 45 will when I get it!
