Have either of you managed to try it on a 5D3 to see if these issues crop up?

No MA on this on tests at 50x FL. That's what I use.<br />http://www.flickr.com/photos/16897255@N05/sets/72157638255646474/<br /><br />Gearóidhttps://www.blogger.com/profile/12867502620689884981noreply@blogger.comtag:blogger.com,1999:blog-6765715422254587392.post-45630965165515403052013-12-01T02:30:47.396-05:002013-12-01T02:30:47.396-05:00I've the same focus problem with mine (the non...I've the same focus problem with mine (the non-sports OS lens). It focussed fine in tests but the Servo AF is lousy with my 1Div. I also have the Sigma 300 EX f2.8 and its AF with the 1Div is way way better. I've not really tried the 120-300 with my 1Ds3 but will give it a go today as I'm going to a cross country race. If it's better, I'll let you know!<br />Garry Lee, Cork, IrelandGearóidhttps://www.blogger.com/profile/12867502620689884981noreply@blogger.com
