If you look on the first picture around the brightly illuminated shoulder of the competitor in blue you can see a purple halo. You can see the same around the back of his opponents head where there is strong contrast against a bright area in the background. It is more controlled in the second shot although there is still some evident.
It only happens with the 85mm around areas of harsh contrast like that, and it is probably that otherwise excellent lens's main flaw.
Would the 100mm be better for wrestling? I am not sure. It's a third of a stop slower and 15mm longer but otherwise it could be the 85mm's twin. It has the same superb optics and high focus speed. The lenses are very similar physically too (I often have to resort to reading the numbers when I take one of them out of the camera bag so I know which one I have grabbed). The purple fringing issue is still there occasionally but it takes a lot more to provoke than on the 85mm.
They are both very nice lenses.
Ah, Yes...the purple halo is clearly visible on the high contrast area...it's even in the hair and the head of the other wrestler too...but I still love the overall (always sharp) results from the 85mm 1.8...
Wrestling fans can benefit from these lenses:
I have a 70-200mm 2.8 IS for indoor shooting...however, am still considering the prime 135mm L for indoor events...(I'm in a pickle, cause I take indoor shots at a concert venue as a hobby and can't bring in a professional zoom lens in)...since I already have the 85mm, the hundred would be real nice, but I need to consider the 135mm for shooting form further back...
Eventually, I'll work my way back to sports...It should be no problem for me, as I personally was very active in the area through out the state and region and nationally too...Again, as a hobbyist, there probably won't be a conflict of interest, if I shoot at some local events, with the permission of the coach, and/or school administration...
I think the 100mm, 135mm, 200mm, would also be fast, sharp lenses for wrestling photography, when shooting from the nearby stands....
At home meets, it's a lot easier to get close to the mat, but away matches don't not always provide the most optimal seating for good action shots...
Don't I wish these digital cameras and zoom lenses were available back in the old days...there would have been so much excitement to share with so many students, faculty and friends and the media too...
Enjoy the great sport of wrestling...
