So, I am delving into manual focus lenses, cheaper with better quality glass compared to comparable auto focus(thats the idea anyway)..and I cant use auto focus for astrophotography. I just bought this lens for 399.00. It doesn't have much testing as its only been out for a year. Headed down to Death Valley but will be stopping at Ochoco Forest first..(supposedly the darkest skies on the west coast of the US and easily accessible but very cold as its 5000 feet up). Want to test this lens down there. So far for astrophotography I can say that zoom lenses suck as they don't focus well enough, even at higher f stops. Surprisingly, the canon 100 mm macro is great for night photography..it is just an amazing all around lens..who would've thought. Tried the 50 mm 1.8 canon..it's okay..but coma is bad. I am finding that the best way to test a lens is night photography..the chromatic aberrations and coma are easily determined with a dark background. And for focusing, the better ability to focus is determined by how solid stars are as you magnify the image. I am hoping this lens performs well for me, or it's on to buying a Zeiss
