What is the lowest shutter speed you run off your camera mount before you get blurring ?

I took this one at 1/200 sec, ISO100. Focal length was 35mm. I had motion blur in only a few of that set. There is almost always enough light during the day for 1/500 or 1/800 so motion blur hasn't been much of a problem.

Thanks Mark
I am just trying to get a benchmark of other camera mounts including homemade and commercial ones.
I'm working on getting the lowest values.

My digital A40 is limited to f8 but the EOS5 will run to f22 and will go lower shutter speed than the digital does at 1/100 but then has a much faster lens.
1/30 is the aim but may be a bit much to expect.

These are small sections of a few taken several minutes later as it was getting darker. This one was at 1/100:



and this one was at1/50:



Again, both at 35 mm. So for my own shooting, I will keep bumping up the ISO untill I can get at least 1/200 and more than half of them usually come out ok (at 35mm focal length).

The lowest I have is this.
The back and edges not so sharp
I cropped it.

That's pretty amazing, Walt. What fraction of the ones you took came out sharp like that?

MPA,
It seems you have some real issues, and they are not aerial photo related. This is just an observation from reading your posts here and elsewhere.

Putting that aside I will address your question. I do not shoot digital, so to show the photos here I scan the film. The scanner has some auto features and the sharpening was on when that frame was scanned.
I do not try to shoot at low shutter speeds unless the lack of light requires it to get exposure. Hence my only low shutter speed examples are night time, sorry.

I have posted examples here to show the possibilities, not for your review. It is very unlikely you or anybody else here will be, or are thinking about being my customers.

My business has been my sole source of income for 13 years, so I must be doing something right; I hope you are as fortunate.

Another image from the same shoot, all scanner options were turned off.

I´m one of non posting members some months ago, exactly the ones I needed to develope a new kind of camera mount. Along this months I never forgot to keep an eye on this forum to see what´s currently cooking and of course it helps me a lot but unfortunately not all of us have the same experience to help the others and/or as my case there is no new results to share.
I´m not familiar with html codes and is quite difficult for me to know how to place pics in those cases I thougt I had and interesting image for all You to be showed. The only way I found was to place the URL where you can find it (like the co-axials rotor post last 13feb03) but nothing to do with my own hard-disc saved pics.
Of course the other way is to use the gallery but Pay-pal requires credit card and no debit ones because it needs three f.. numbers that my card hasn´t.
Will be glad if someone can teach me in how to do it to became a new active member as soon as I can start testing the new mount.

Regards
Elossam

Pd, MPA, no one of the pics in my web were mangled with sharpening tools. Some looks better than others but there is not any trick and all at 1/50

Hi,

just thought I would jump in on this post. we shoot for a variety of clients here in indy since 1997 and compete with top notch photographers in our area. we have accounts with some of the most discriminating companies. We shoot all of our rpv shots with a 35mm slr film camera with a 24mm fixed lense. check out our low altitude section at http://www.skykingphoto.com - we use 1/750th for all the shots in that section.

Hi Mark

Thanks for the input but I do have to ask, why do you shoot at 1/750 ?
And are you claiming it is more suitable for some reason ?

mpa,

my home made mount is not vibration free and 1/750th has proven to take out all blurring in the pics, even in windy conditions. the 24mm lense still lets in enough light to work in higher f stops even at that high of a shutter speed. I agree with your thinking on lower shutter/higher f stop when you get into longer lenses. BTW we will soon be purchasing the v2 mount from airfoil, and hope to start shooting video this yr too.

MPA,

I was responding to a topic YOU started titled “Whats your slowest shutter speed”. Several responses showed their work at their lowest speeds, I thought I would show mine. You have taken this thing to another level, maybe you should have made a different name for the topic like “why do you shoot at a high shutter speed” or “I know how to get good shots do you ?”.
If you would like to start a topic of “do you get good DOF with high shutter speeds” I can post some examples for you to look at.
You asked me for daylight examples of low shutter speeds, and I said “sorry”, it meant I am sorry I can’t show you any because I don’t have them. As I said I don’t shoot at the lower speeds except in low light conditions.

Back to the topic as it has morphed, Your need to use lower shutter speeds and higher f may have to do with the “digital” camera. I have an A70 and Dimage7 and both look better at lower shutter speeds. I find film isn’t as picky. I have shots at high sun angles (to my back or quartering) that are in focus to infinity and shot at 1000 th. The problem with a helicopter is with all vibration removed from the mount there is still aircraft movement. Even if there is a better DOF at the lower shutter speeds the potential for a blurred subject is greater.
