Lagerloef Loc: Sugar Grove, IL. USA

I just returned from a trip where I had the opportunity to photograph lots of old airplanes, indoors and out, inflight and static. The 16-35 F4 on my 5D4 didn’t miss a shot. I did use a telephoto for some of the inflight shots but the cloud formations were so spectacular that with some cropping the 16-35 was excellent even in those shooting situations. It allowed me to capture the aircraft airborne with great backdrops of majestic cumulus clouds. Where it really shined though was indoors capturing large airplanes (Concorde, Lancasters, B52s, B17s, Comet...) in fairly low light from nose to tip to tail. The IS really mattered. The clarity was excellent with the wide angle shots. The lens was the perfect choice.

The 16-35F4 IS is the first EF mount that has good corner to corner sharpness. Previous versions, Canon wasn't known for great UWA lenses. I have the v2 2.8L and my friend uses the F4 with IS. It's noticeably sharper than my copy. Although that focal length doesn't particularly need image stabilization, any stabilization is meritable handheld at F8 or above in low light.
