Hi folks

I bought a 2nd hand sigma DG 70-300 lately but I cant get it to focus at long zoom.
I have taken these photos at the different marks on the lens and as you can see it got blurry at 200 and 300.
Do you think is the lens faulty, and if so is there anything I can do about it?

1/60 sec is WAY too slow to obtain a sharp image....too much motion blur
 
Rule of thumb, shutter speed needs to exceed length. So at 200mm don't drop below 1/200.
 
Windows 7 !!! just saving the file to my desktop, right click > properties > details

then deleting the photo :)
 
Is this lens image stabilised? The only real problem I can see is that the image is sharper on the left than on the right, which I know has been a problem on some Sigmas, particularly older batches of the 10-20 lens.
 
Assuming that you didn't have your camera on a tripod it looks like your shutter spees is way too low. I suppose that the easiest way to retest is to crank the ISO up and take some more shots.
 
Thanks for this guys :thumbs:, I will try speedingup the shutter and see if this works
 
Thanks for all your help, I was able to speed up the shutter speed to a max of 1/250 and it seems to have worked

I use Google Chrome to browse, and you can get a little Exif Data Application that reads it direct on the browser... its very good...

Firefox has some great EXIF plug-ins available. I forget the name of the one I use... either way it's much more efficient than saving and deleting stuff! ;)
 
Opanda IEXIF 2 is showing the exif on these pics using Windows 7
