I have recently purchased the 300mm and paired with the A1 and the 2x tele but i'm not overly impressed with image quality compared with my 600mm f4 , I know some users have said it's great and hardly see the difference between to two set ups but i'm just not seeing it , I have been shooting BIF early mornings but in good light but images are very grainy and out of focus shooting at 5.6 max iso of 2000 and shutter speeds of 1600-4000
