This was somewhat lost at the bottom of another thread. I have been requested that i post it as a main topic. Which seems a good idea
Talking of the 300 mm L f4....
I have a 70-200 L IS USM
f.2.8 and its a cracking lens , brilliant and everything i wanted and expected for a lens that costs £1200.00.
Now i also have a 300 mm L IS USM
f4. I have been VERY dissapointed with the results so far,seeing as its L glass, IS
and £900.00 !!!! All the results so far are very soft and even worse than my fuji point and click. Im pretty sure im doing something wrong or i have a duff lens
I tried the 70-200 today without problem. As soon as i put the 300 mm on the results were awfull. Even taxing aircraft were blured at 1/500 f5.6 !!!!!!!! The pictures of close subjects (ie a cockpit window) are ok'ish. But aything at distance (ie a plane taxying etc etc) are blurred... Not alot of use seeing as i got the 300 mm for distance work.
I know my settings etc etc should be ok as the pictures on the other lenses are fine....I tried to add my 1.4 II
Extender and the results got even worse. Is there any test i could try to complete to see if its me being think or infact a faulty Lens ..
Help anyone !!!!
