Lenses / 16-35 f4 infra red use
« on: June 24, 2014, 09:19:06 AM »
I've just received my 16-35 f4 today and took it out for a bit of testing. I'm impressed!

I have noticed most shots seem under exposed by a stop or two but I need to investigate further to see if it was my fault...

I did try some infra red with a Hoya R72 filter - very clean images with NO hot spot, wide open & f11...

Just thought I would share this info as a lot of you are keen IR shooters...

edit - Another thread has this info...- http://www.canonrumors.com/forum/index.php?topic=21039.0
