I rented the 200-400 and took it to my local airport. With my 1D4 I shot a number of prop and jet planes. Hand held and at various shutter speeds. Most were with the 1.4x engaged. A few were with an external 1.4xIII attached. I was surprised how well some of these shots came out at 784mm.

Note: this is not a lens test. But it does give one an idea of what this lens can do for aviation photography. I'm sure some are better at panning than I, so keep that in mind. Images greater than 560mm were taken with an external 1.4xIII attached.

Yup... animal fur is a great sharpness test subject!


My entire hobby of gear lust has temporarily been shifted into overload. Please be patient while my mind tries to get back onto the road to recovery. We do apologize for any inconvenience this may cause....

One is a t 1/160th at 645mm! - Probably for the 'prop blur'? - Mind you, f/16 - f/18 doesn't help as diffraction will be softening the images.

A friend of mine has bought a 200-400 (:mad:) and even with a separately attached 1.4x converter it is capable of superb results.

Aviation photographers shoot at slow shutter speeds to capture prop blur. But I agree, many are a bit soft, even the jets at higher speeds. I didn't apply any sharpening.

At 1/180 you're introducing alot more camera shake than prop blur into the image at that focal length I think was the point.

There are more than one or two shooters out there that can nail 500mm and 1/60 quite regularly. I'm sure the keeper rates are not high, but they do it consistently. Many think that 1/160 is almost a maximum shutter speed for propellor driven aircraft. So if you are at ISO100 you either stop down or use a filter. If you then want to quickly move to a jet at 1/1000 then the filter is a bit cumbersum.

Helicopters usually need around 1/100 or slower. The bigger the helicopter the slower you usually need. Things like Seakings won't come near to showing a full disk blur (which would take 1/5th of a rotor rotation) at 1/60s shutter speed.

With two 1.4 TCs on a 1.3 crop camera, one should be able to hit at 1/1000" with out IS. With 4 stop IS in the 200-400, that should bring it down to 1/60".


Canon 7D/350D, Σ17-50/2.8 OS, 18-55IS, 24-105/4 L IS, Σ30/1.4 EX, 50/1.8, C50/1.4, 55-250IS, 60/2.8, 70-200/4 L IS, 85/1.8, 100/2.8 IS L, 135/2 L 580EX II, 430EX II * 2, 270EX II.

That may very well be. I only had about 3 hours to use the lens, and it's heavier than my 300 f2.8. Perhaps more practice will help. I usually don't shoot aircraft
at greater than 500mm, except for the high flying aerobatic planes. I just wanted to see what the lens - and me - could do above 560mm.

Although even at 1/750s my jet shots are a bit soft. Adding 3 or 4 points of sharpening in dpp cleans them up pretty well.

I use a filter in my 300 f2.8 to keep the f number reasonable. But I forgot to bring it with the 200-400.
