Hello guys, new member here (currently a Nikon DX user, flirting with Canon FF)
Anyone (esp. MrPhotoEditor) having any info how this lens performs in infrared? The 17-40 did an okay job but the 16-35f/2.8II had a bad hotspot which made it worthless for an infrared shooter like me.
I'd be interested to know this too, I've been using m42 lenses to get around this issue...
Graham Clark Photography is planning to review the Canon 16-35 f/4 IS as soon as he will get his hands on it. I asked him to review on a few aspects and that includes the infrared. He confirmed that he will review the performance while using it with infrared. Now it is just a matter of time to wait for the review.
