The auto mode of your K-70 DSLR brougth out pictures of of Nikon Z DSML camera?
  1. Depends on the lens and camera used, distance, size and speed of the bird as well as direction of flying

  2. first use a good lens, then a good camera. Then you don't need software.

Good Lens for sharp images of animals in movement would be the Pentax D FA* 70-200mm 2.8 or D FA 150-450mm.
Perfect camera will be the K-3 III.

On the K-3 i'd recommend the D FA* 50mm 1.4 SDM.
If it's to long for you use in in combination with a (rented) K-1.

No.
The only hood which fits the D FA* 70-200mm F2.8 ED DC AW is the PH-RBM77.

So no written knowledge will remain after the video get's unavailable or unknown.

I did back up every statement i wrote by a separate link to prove, so you exposed yourself as permanently not telling the truth.



Only simple product links everyone knows, not any real technical proof of your claims. And it is obvious that i know the products better even without owning them.




You are unable to proof your claims, that's why simple products links are the only thing your claims are based on.

Peoply with technical knowledge can check the facts i already posted.
As well as the difference between cell chemistry and battery type.


Correct is that they both use lithium-ion technology.

This is possible with opinions, not with facts.
Spreading wrong knowledge without accepting the facts isn't acceptable.

Obviously you don't know. I did prove it already, you can't.



That might be correct.



Knowlege can be proved, believing can't.
The difference between believing and knowing is clear.



Then the question is why you spread fake information here.
My correct statements are with references and easy to check.



This is obviously wrong.
Correct is that they both use lithium-ion technology. The D-Li109 is a battery using lithium polymer cells.

That's still wrong.
Of course all of the named phones use a lithium polymer battery.

It's easier to know this than to spread wrong knowledge.

Label is technically not correct.

Smartphones always use flat Li-Po and never cylindrical Li-Ion.
That's why your Li-Po's from your phones did also swell.

Oh i know about batteries and rechargable batteries. So i can help you with missing/wrong knowledge.

First there's a big difference between cylindical Li-Ion and flat Li-Po batteries.
Li-Ion can't swell, Li-Po does.
unmannedsystemstechnology.com/feature/lipo-vs-lithium-ion-batteries-for-unmanned-robotics-applications/

K-30 battery is Li-Po (flat calles), so it can swell especially if you buy cheap third-party products.
Pentax D-Li109 battery for the K-30 - has anyone else had this happen? - PentaxForums.com

D-Li90 (K-7, K-5, K-3, K-1 ) is Li-Ion, so it won't swell.

No, Li-Po can swell - Li-Ion not.


Lithium batteries are not rechargable and don't burn/explode.

With 3D printing per demand there's no need of a market to make production cost-covering.
You can even use kickstarter if the product is fninished and the demand exceeds your expectations.

16-50SDM vs 16-50PLM
Posted By angerdan

It depends on the camera you're using currently:
  • If it is as old as the 16-50 SDM (2007) or even older, get a newer camera.

  • If your 16-50 SDM is older than your camera, get a new lens.


If you don't see the advantages of the PLM and like your lens, maybe just keep things as they are.

Start using automatic exposure, automatic white balance and correct autofocus point(s), so your results willl become better than your skills.
