Aperture Priority Vs Shutter Priority

Hi All,

Today I tried using shutter priority. I was shooting fast millitary jets so I had the shutter set between 1/640th and 1/800th sec but for some reason the shots were coming out blurred. I was using Al Servo mode. Where am I going wrong? The one's I shot on aperture priority came out much better but I used that for taxiing shots. I also set the image stabilizer to 1 on the lens.

I use shutter prority in most crap weather situations and get sharp shots upto 1/320 for normal a/c's( I use IS). If I pan, the speed could still be lowered. (I never use AI servo)
I guess, your problem could be with the focussing point not locking on the subject when you shoot (due to the AI) or may be the jet is too fast for your speed(I'm not sure). Mode 2 of the IS is what I normally use.

Sorry but the EXIF says 1/160s, and I think that's your answer.

Back to the drawing board. I'll try and find another one.

Here you go try this one.

Even at 1/640 second, you need pretty good technique to get a crisp shot with a 350mm lens. A monopod might help, but if you get really close to the runway it might get more in the way than help if you have to turn quickly...

It seems that your lens does not like F5.6 very much although I don't know what you are using.
On a F2.8 it would have been just fine but I get the impression that in your case the lens is wide open.
Further I can see that the light meter is fooled by the little light hence the dark exposure, a different technique would have been beneficial.

For jets I use aperture priority at f8 with VR (IS on Canon) off unless it is dark and shutter is below 1/250 th sec. On prop aircraft and helicopters I use shutter priority 1/250 or below with VR on and in both modes I always pan with the action. In twilight I have used f2.8 at 1/25 sec with VR on and got an acceptable image.

As expected.
Although the 100-400 is a nice piece of machinery it's not at its best wide open(according tests and other users).
Try to stay around or at least close to the sweet spot, you have to ask another user where it is though as I don't have a 100-400.
Probably around F9 though.

Use both Tv and/or Av with a specific reason and not just because it seems the best option.
Personally I use Tv to achieve Prop blur or panning and for pretty much everything else Av although I have to admit that manual is my absolute favorite for sure in the situation you were in.
With the light sky and dark background with dark A/C equipped with bright lights it is almost impossible to rely on the light meter.
Nikon shooters might get away with it but we poor Canon users have to make use of a work around.
A light meter would be the best option but if you don't have one(like me) aim your camera in the direction of the action without any A/C in view with your cam set in Av and the preferred aperture(F8.0 for example) press the shutter half way and check the shutter time you get, not satisfied increase the sensitivity until you are.
Now switch to manual and dial the whole lot(aperture, shutter, ISO) in.
You are pretty much sorted for anything that comes along.
The above is my way of working which by no means is the only way of working.

Good luck next time.

Try f8, it works pretty good for me.

Mode 2 is indeed to be used while panning. Mode 1 is for steady shots (or relatively slowly moving subjects).

Another - not well known - "problem" of the 100-400 is that it needs refocusing after zooming because the focus point shifts (moving forward or backwards). If the zoom ring is not tightened well, the lens can zoom unwillingly because of its weight (certainly while performing a high speed pan when shooting fast moving jets from close-by and when a certain degree of upward tilt is involved). That, at least, is my own experience, me and my old 300D are achieving less than 20% keepers in such circumstances...

Best regards,

Walter

I do move my lense while taking all my shots in the panning style, fast or slow to ultilise the IS. it worked so far better (sharper, I use 1/320 secs except for sunny days where I use F8)than the mode 1 steady. For static subject, I use mode1.

What do you mean with mode 2 for panning? I am currently experimenting with panning shots myself. I had a panning shot just two days ago in the late afternoon but the photo came out a bit on the softer side, why is that? The weather was hazy with little sun and I used f8 with my Canon 350D (EF90-300mm 1:4.5-5.6 USM lense). Any tips on more panning settings? Somehow my photos still come out blurry and soft. I use Av-mode with f8, ISO 100, AI Servo. Are other settings recommended for panning?

Since you are trying panning, that is, low shutter speeds, I suggest you use Tv mode, choosing the speed you want to work with and letting the camera set the aperture.

Canon IS lenses have an IS mode designed specifically for panning shots.

What Tv mode settings are recommended for panning? Does this solely depend on the weather conditions or is there a "guideline" for panning photography?

Well,

I did some panning photography but all photos came out blurry and soft. The weather was hazy with the sun appearing and disappearing constantly. I did notice the photos with more sunlight did come out slightly better but still very bad. I tried out Tv-mode at 1/40, 1/60, 1/125, 1/100 and 1/160 but with no good result. I only got lucky with one banking shot which is in the qeue right now.

How come the photos came out so blurry and soft? My lense also got very dirty all of a sudden with a lot of dust spots which I don't understand entirely because my first photos didn't have any dust spots at all but my photos taken later that afternoon were full of dust spots.

Any tips?

Hi J, yes I have read it but I overlooked the part of the sensor dustspots becoming very visible. My apologies, but how come the dust spots become so very visible when panning? Is the sensor extra sensitive to anything on the lense that is close to the lense?

Dust spots become more visible the smaller the aperture (the higher the f number). If you shoot with plenty of light and you use relatively slow shutter speeds (as you do when attempting panning) you will be getting small apertures, so revealing all your sensor's dust spots. A way to avoid that (if you want to pan in full daylight) is to use Neutral Density (ND) filters, which reduce the amount of light getting to the sensor.
