I hope you are right. I have seriously thought about returning my D-FA* 70-200mm after using it on my K-3. Not fast at all on the K-3. I keep holding out waiting for the K-1 to ship.

My 70-200 has been very quick on the K-3ii. Not much room for improvement on the K-1 although I am sure there will be some. It has been decisive and accurate.

That's 150 mins each day on the road.. 2 and a half hours of your life is spent daily on driving. eep. That makes me shiver even thinking about it.. that job must be incredibly nice!
She's incredibly important to me. We work very hard to keep the atmosphere positive and happy. I'm much nicer at work than here. I drive 250 minutes a week.

She is home at 5:00pm. I ask her to be at her desk 35 hours a week 48 weeks a year.

Then you'll be disappointed with the lens on the K-1 as well. The K-1 may remove some hesitation but it cannot speed up the internal AF motor of the 70-200.

According to Kenspro the lens is faster on the K-1.

It appears to be more of a latency issue with K-3. The IQ is excellent and AF-S is nice and quick with no hunting even in dim light, but AF-C when subject is doing more than walking towards you is not very good at all. My Sony A7II with 90mm macro tracks better in good light, but hunts like crazy in poor light.

As they corrected - in LV.


It was strange for me to hear it, because the user of DFA70-200 with K-3 said about good speed.

DSLR lenses are not made for LV but PDAF.

It is fast on K-3II, but faster on K-1 when i tested. The 70-200 is made specific for the K-1..Why he said that, i have no clue Of course, not D5 fast, but very fast in Pentax terms..hehe

This is the AF-C in the K3. DFA 150-450 is the same. Whilst not a game changer for me, I'm hoping for a significant improvement in the K-1 over the K3 performance on this aspect of focus performance.

Like ClassA, i hardly can believe different speeds with the same AF engine driven lens, according to the body used.

What i can testify, is that DFA*70-200's engine is slower than DA16-85's, that goes as fast on my K20D as on my K-3.

Whilst hunting from zero to 3 or 4 steps depends for sure on the body, and also AF-C performance.

Well, the AF on cameras like the Nikon D4 isn't that fast actually, it is the lenses which do matter for action and their AF motors which do matter and are fast, like 70-200/2.8 or 500/4 or 600/4.

In that regard, I would be surprised to learn that Pentax hasn't put a competitively fast AF motor into their new DFA* 70-200/2.8. Kind of defeats its reason to exist.

Do we have *any* specifications about the kind of AF motor Pentax put in the DFA*70-200/2.8? Like ring-type, torque etc.?

At http://www.bhphotovideo.com/c/product/1117718-REG/pentax_21330_hd_pentax_d_fa.html , I read the lens AF has a DC motor. Well, that would be a bummer, not adequate for a sports lens IMHO. Same says http://us.ricoh-imaging.com/product/d-fa/hd-pentax-d-fa70-200mm-f2-8ed-dc-aw-wcase
