One should fool oneself; a 70-300 zoom somewhere must also have a weak point - but only one; easier resolution drop at 300mm on the A55, at the A300's all OK (16MP 10MP against that takes its toll ...) - that's it. Otherwise, the appearance is awesome, they have to an Alpha 300 and Alpha 55 with great success in use. What distinguishes the optics, is above all the speed of the SSM. As a little escape motives, even fast moving; Focusing almost at your fingertips! In addition, the appearance still is relatively compact and not overly burdened traveling. I have never regretted this financial issue.
