To slow and to shallow

That’s a significant improvement in AF performance, nice demo Kobie. Did you have SR set to the dedicated panning mode on the K3iii?

How does the Pentax K3III compare with a Nikon D500 or Canon R6?

1/250 is nowhere near to achieve sharp birds in flight. 1/1000s… and some large aperture lens so you can save some light instead burning the sensor with hig ISO 🙂

This was one of the more useful reviews. I’m still not interested- there’s too much out there that surpasses these results.

Real honest hands on approach and testing! It’s greatly improved!

Great video Kobie I don’t do bird photography that way I wait until I have focus before I take the picture. Maybe it’s because i use the old 6 megapixel cameras occasionally the *istDL and K100D.

Goes to confirm that the AF-C improvements are significant enough to make a difference in RL photography, and a marked one at that. I’ve tried to track seagulls before with my K-3 and the old DA 55-300, and though it wasn’t utterly impossible, even with working on one’s technique, the hit rate wasn’t anything to write home about. It’s a beginning, it may not be quite D500 level yet, but we finally have a Pentax that actually tracks, and I’m sure they will further refine it from there (firmware updates, more PLM lenses, Ricoh?). Thanks a lot indeed for performing your trials, Kobie.

If you need samples of motorsport images and real life AF check my post on pentaxforums I did about the Monaco E-Prix 2021 where I was able to test out a K3-III and its autofocus and there you can see a 12 images burst of a car coming full speed towards us and those are jpg as they came out of camera. There is more examples you can check out. What I found is that non-prefocusing maybe you loosr the first 2-3 images but prefocusing if you can, you might not loose any or rather a few images at some point in very hard conditions (car is sliding/turning) and you can literally not move, and there is a bit of a fence close to you, but its all good when you can pre-focus.

Great review as usual Kobie.

Thank you Kobie, that’s very encouraging.

Still buy k3 mark 1 now used for first camera?

Interesting test! It’s also good that you have not waited for the focus confirmation before taking the shots because that’s where Pentax is really slow at AF-C. It shows that the older models take aaaages before the first focus confirmation.

Now, if you could please sell the K-3 mark 1 and compare the K-3 mark iii to the KP. I heard that the KP’s AF is not too bad. Not K-3 iii good, but it would be interesting to know how far the gap is between the two latest APSc cameras. Cheers!

Nice video Kobie, exactly the kind of stuff I want to see! Great comparison.

Kobie, I don’t understand the test parameters for this, it’s almost like you’re trying to highlight worst case scenario for both photographer / camera technique.
Going from defocused to in focus shows how quickly the camera can identify / calculate subject and send calc to lens. The iii won that handily as you would expect 🙂
The K-3 did better holding focus over the iii in your next comparison :p which is more user technique failure, some of your shots have the seagull in the top left hand corner of the frame and not closer to the centre so you’re pushing the AF system and running into lens limitations (it’s a fine lens for its price but don’t expect ultimate sharpness across the frame).
So going by the images you presented, the K-3 can be helped by prefocusing and once locked on will hold pretty well. :p see where I’m confused about parameters of test?
Btw, not sitting on fence, I’m awaiting delivery for an early April preorder. I’m subscribed too but this video came across as a bit confused.
Keep up the good work!

The lens is the problem, 55-300 plm can not do it. I get better resultat with the K1-ll and 150-450mm. Even with KP. Had 2 copies of 55-300plm and they are worthless in tracking and finding the subject. Try the same with the 150-450mm set the Focus limiter. Both cameras will do much better. They will hit from first shot.

That was exactly as I expected, you were ruthlessly objective (thanks for that!) and the new camera meets expectations and promises. I’m curious to see how it performs with old workhorses, though. like the Tamron 17-50mm, the 18-135mm DC WR, the 20-40mm, and some of the supreme values for money in the first Generation autofocus zooms, like the SMC F 35-70mm f3.5-4.5. I can’t do a test like that myself yet; I don’t have $2K to spare in my budget yet.

You “tested” the new AF of the new camera, with only one new slow aperture lens for a few days? Not even knowing all the new options (including the metering) and what they do? And now you are offering a conclusion on the K3.3 in general? The bottom line is, you have no idea YET about the gear, but are rushing to be the first offering conclusions, not even bothering to use superior optics? Goodness me…
