Just a comment about focus accuracy. Whether it;s a person or an animal...I always aim squarely at the eye of the subject. If the eye is in focus, then generally the rest of the subject is in pretty good focus. I know, I know...probably every photographer knows and uses his method, but...I thought I would just add it to the mix of suggestions.

Interesting reading . First time I used AF was in 2007 with my new K10D and 16-45. I thought I had died and and gone to heaven. :lol: But then I came from a long experience (started in the late 1960's) of using nothing but manual focus cameras. Cameras I used back then included old Pentax film bodies, Mamiya , Zeiss Ikon and Yashica medium format, Leica rangefinder, etc.
I was pleased with how 'fast' my K10D and my next new lens (55-300) focused automatically...quickly I thought (perhaps in error after reading these posts) :D on everything from squirrels, Chickadees, pelicans, drag racing cars (and moving smartly along, at that) :D.
I've continued along, getting a K-5, K-1, other lenses from wide to tele and generally been happy and got a good number of keepers...as long as I aim my lens...for the most part the AF follows through well. So much faster than using my old manual focus lenses and trying to get any kind of accuracy with speed.
I recently got a Pentax 100 F 2.8 Macro for my K-1 and other Pentax bodies. It was an Xmas present and I used it to great effect taking pictures of my 11 month old grandson. He is a fast moving little monkey :lol: and I have been mostly using available light...indoors...3200-6400 ISO, F 2.8 and for the most part I've been able to get some..what I consider...really sharp pix of our boy. :D
I think the DF A Macro 100 came out around 2010 and I recall the reviewer from Pop Photography magazine saying something about the 100 Macro being 'superb' or something like that. So to me and judging by it's performance...it's sort of an oldie ...but a goldie...IMHO. I guess it is around 9 years ago when it came out and I think it may have been based on the previous Pentax 100 Macro...and now that I think about it...it probably does make some AF noise...but if these deficiencies hadn't been brought out as typical for Pentax glass...I don't think I would of noticed. :D
I think my problem is that I haven't the the latest from Canon, Nikon, Fuji...et al...so I don't know what I'm missing and also considering I used manual focus lenses for decades...I maybe more impressed with the Pentax AF system than I should be.
But so far the Pentax AF works well for me...in low light...available light...indoors. Part of it maybe the high ISO performance. Back in the film days if I pushed B&W 400 ASA to 800...the grain was big enough to trip over. But now with modern cameras like the K-1...the high ISO performance at 3200-6400, etc..compensates well...higher shutter speeds and very good results.
That is my experience and I'm not a pro, just an amateur, a hobbyist...so my standards could well be different.. As others have said..you got to go with the equipment you like and have confidence in. Go with your preference.
