comment: | i think the sharpness is great on this lens. i looked at the photozone review, and perhaps the far corners are soft wide open. but towards the edge is fine, and centre is completely sharp. sharpness really isn't an issue. the bokeh of the the lens is fantastic. a bit of optical vingetting wide open gives it a bit of shape towards the edge of the frame, but the spherical abberation is almost perfectly corrected, which leads to perfect disks, and a great sharpness in the plane of focus. i am very happy with this lens. i'd rather use this 30/1.4 on a crop sensor than a 50/1.7 on full-frame. the 50/1.7 on full frame would have resolution going for it, but this 30/1.4 has the out of focus characteristics nailed, and that's what affects the overall feel of the image more, in my opinion. my copy focuses very accurately. it's a great walkaround. |
