FA* 300mm/2.8 vs DA* 300mm/4, how does it compare?

Apart from the f2.8 vs f4, care to share your opinions/facts between the IQ of this two lenses ???

Thanks

My FA*300 f2.8 was not as sharp as my DA300 even at f4 with the DA wide open. It didn't sharpen up even stopped down, but it was obviously not a good copy.

I did play with both for a few shots today and so far my opinion is this:

I cannot tell them apart in terms of sharpness. If I were to look at 100% for a few minutes, I would say the DA* is 0.2% sharper.. as in you will never notice it in print at any size.

The FA* is cooler or the DA* is warmer for colors depending on how you look at it.

The FA* does love to PF compared to the DA* which has nearly zero that I could see.

In my quick test opinion, so far there is no real advantage to the FA* over the DA* unless you must have the 2.8 as I must. (I work as a photojournalist and product photographer - fulltime working pro)

I will try to compare with photos as soon as I have some time. I will post my results when I do. Today was just a five minute quick look just to get an idea. This is not my final word or opinion.

Albert, the difference might be even more for someone wanting to use TC's with theirs, especially the 1.7X or the 2X versions. I wonder whether you believe in TC's, and if so, mind posting some comaprision shots with those.

The FA* has faster AF and focal limiter (which again speeds up the AF-speed)
