I'm wondering, why most of the pictures are blurred? With this class of camera you would expect a perfect autofocus in any object position within the frame...

Some lenses suck so may be it is one of the cheap lenses, that is not fast enough ?

Just curious....

Thanks,

I find it curious that the shadow looks more in focus than the canopy, very cool none the less!

I would say that it looks out of focus because the shutter speed is rather slow given the speed of the object, I'm sure with some fiddling it will be better. Camera was on auto exposure so it could have metered the sky instead of the object, some manual settings can easily cure the blurr.

yeah, i thought about autoexposure too, but on the other hand with 1/400 you should be able to nail that canopy pretty sharp...

may be you right...

(i am just thinking about getting nikon d100 since i have 2 their reasonably good lenses, and got a bit surprised that even with high camera one could not get them sharp... not that i did on my slr, though)

cheers,

Blade blur reflects the ISO 100 setting (drives shutter speed slower). Most of the shots were at a zoom focal length of 300. All where moving. The higher I go on the ISO the less blade blur is shown. I feel some blade blur is desirable.

I appreciate the feedback and will go out again (testing) and try a slightly higher ISO.

Hi Mark,

Sure. Let me see the draft. I can forward higher resolution versions later.

Mark,
my 2¢...

use max allowed lens's aperture and let the camera determine the speed. if your lens gives you full f2.8 you should not have any issue with the taking shots at a long focus (aka hands shaking/moving). 1/400 could be too slow, who knows...

the higher ISO the worse image quality....

i would continue shooting at ISO100 (in bright conditions)

my question was related to the blurred canopy, not the blades. blades blurishness is a perfect catch IMHO !

good luck ! and very nice shots.

I found the same problem with the Canon lens Mark. Its just not good enough at extremes of focal length and the pictures become out of focus in some areas.

I switched to a Tamron 28-300 on my Canon D60 and cured that problem at a much lower price.

This was taken at Circumgyration at 300 mm on auto.

Check out the crispness of the picture detail and compare it to yours. You wont be happy with that Canon lens in the long run.

AGREED!!

Using the Tamron also on a Canon 10D, and I have to say even at 300mm (300x1.6 actually=480, due to the Multiplier factor of the sensor) I get EXTREMELLY sharp focus...

Hats off to Canon for making such an incredible camera...I am never going back to film! :-)

FYI...

I always used ISO 100 on stills. In your pics the camera shutter speed has captured the rotors moment very well. how much can it be enlarged either on paper and or computer before the resolution looses it sharpness.

the pics look excellent mark. What printer or paper would you consider for prints.

cheers

Tamron 28-300
I am testing the new just released EF 28-300mm f/3.5-5.6L IS USM lense. I will report back with some more images.

Thanks and I use a DeskJet 990 Cxi (office all purpose) and HP photo paper.

here you go... with the lenses that are marked as f3.5-5.6 as soon as you go to a full zoom, they are only capable of opening up to f5.6 of higher and obviously all you can do is to increase the ISO and keep the speed high, or keep ISO at lowest possible value and lower the speed. lowering the speed could cause blurrishness on moving subjects....

unfortunately lenses with f2.8 fixed thru the full zoom range are multiple times more expensive than those with f5.6, since they let you shoot at lower light conditions (lower ISO numbers...)

Re: Canon EF 28-300mm f/3.5-5.6L IS USM

From a spec's point of view it looks to be the best yet.

So Mark, what is to become of your previous camera? The one you had at LARKS?
