thanks ereyone for your answer
the positive of the 300 2,8 is when i want to work with a 2X converter , i have a 600 and he is F5,6
negative is that he is very heavy
i now that the 300MM F4 give`s you sharp picture`s and is not so heavy but , is not so good with the 2X CONVERTER maby the 1,4 CONVERTER

i am not so sure of the advantages of the A900 against the A700
POSITIVE
the A900 give`s you a very good IQ and colors by NORMAL ISO
NEGATIVE
if you dont have HIGH-AND GLASS THE profit against the A700 is not much
the AF the manual and the constuction is not better than the A700
a new investment of your computer stuff is necessary
for one A900 you have 3 A700
i think that the SONY A700 much better is than the CANON 40D and the NIKON D300
i think next year sony shall release a new MINIFULLFRAME the ( A800)
if i see the picture`s off the A700 , i think it is one off the best camera`s
a view day`s ago i had a weddingshoot , all of my picture`s are taken with the TAMRON DI 24-75 2,8 and the SONY 70-200 SSM
i shall open a NEW TOPIC later this day , in GIVE IT YOUR BEST SHOT ,
