|chappo1#4468 date: Dec-4-2008|
flare control: 5
|ownership:||I own this lens|
|compared to:||The only other longish lenses I have are 70-300 KM kit lens and recent addition of SAL18250|
|price paid:||1500 $AU new|
|positive:||sharp responsive and versatile.|
Great value for the money.
I have not seen anything to compare to it under several thousand dollars.
|negative:||Weight is my only negative|
|comment:||I have owned this lens for two years and used it on both the KM5D and the A700.|
I read one review on speed of focusing on a KM7D.
I suggest the deficiency reported is more camera related as I noticed a huge improvement on the A700.
The lens is almost invariably used at the 500mm end on birds and I would not be without it. Weight is my only concern and I have modified a sprung 3 wheel golf cart to carry it around the park. The recent (last week) purchase of the SAL18250 is for when I cannot take the buggy.
