Hi all, Been shooting IR w/ my new OM-D for a bit & loving it. Bought the ever popular Hoya R72. Hands down it produces the most flare of any filter I've or did own. Did lots of testing w/ 3 lenses & other filters - its defiantly the Hoya. And we are not talking about a little icicle of flare but rather a giant lolly pop. The B&H web site where I got the filter is completely mute about anti-reflection coating on this & all the other IR pass filters. So do any of you folks have experience w/ other IR filters w/ no/little flare? That you are sure have AF coatings? Testing revealed lots about my lenses & various hoods. I'll post more on hoods later. The factory hoods provide very little shade for the filter. If the Hoya is at least 35% shaded, flare mostly goes away. The worst problems are naturally on the widest angle lenses - my M.Z9-18mm. Zooms are as expected worse than primes. With the 12mm, I can have the sun in the frame & have almost no flare. Until I screw on the R72. I did a search on this site for other comments about this & found lots of discussion about lens hot spots w/ IR. Surprise, when the filter was described they were all - you guessed it - the Hoya R72. Thanks much!
