the FA 77mm Limited vs DA 70mm AF speed

I've been thinking of getting either one, and the reviews say the Limited is hunting sometimes. How slow can it be, especially at 1.8 in low light indoors?

I owned both of them concurrently only for a short time, but I'd say AF speed was pretty comparable, with the 70 being just slightly faster? I ended up keeping the 70, but frankly when all things considered, I would have been just as happy keeping the 77.

I have the FA 77 and had the DA 70. When I acquired the 77, I still had the 70 and I compared both for a week before I decided to keep the 77. The 70 does focus faster than the 77 but in good lighting both are fine. The 77 is easier to MF but the 70 does have quick-shift, which is pretty useful. For indoor shooting, the 70 is still a little quicker but both lenses did hunt a little on my K20D-- I think that might be more of an indictment of Pentax's AF system than the lenses' focusing abilities. However, if getting the fastest AF speed between the two lenses is your priority, then you gotta go with the DA 70.

I recently posted a set of birds in flight on the "Post Your Photos" section of the forums and all of those shots were taken with the FA 77, which was certainly capable enough for me that day.

The 70 is somewhat faster, but not by any significant amount.
In low light the 77 has a theoretical advantage, since it is 2/3 stop faster, but I've never noticed that it makes a difference with my studio lights, which is as close as I ever get to low light shooting.

They both are a Limited series lens.
