AFAIK yes.
Has been better in the K-5, but i don't often took photos in Darkness and even then the AF mostly finds something and the active focus point is illuminated shortly.

That's not true. DA 200, 300, and 560mm have WR/AW.

You can't install an update without the software already installed.
With a small check here you'd find it out.

Only if you know the workaround, how to install the update with passing the check for the existing install.
But this can't be told in the forum.

Quality of memory cards

Memory Card reliability depends on the kind and quality of the NAND and controller.

Many brands like SanDisk prefer to use cheapest consumer-grade cells (QLC) with the lowest reliability.
Best option are memory cards with MLC-NAND. Industrial grade memory even uses SLC.

  1. Inside an modificated Bagpack:

  2. No, it's ony for safe storing. The soft case is not very strong.

  3. I travel by train

  4. This will depend on the airline and ticket class. You can prevent this by shipping the lens per mail (USPS/DHL).

  1. No, because it uses fast screw drive and can take advantage of the stronger motor inside the more recent cameras

  2. This depends on the subjects distance and movement. DA 560 has the advantage of the focus limiter and the AF speed of the Sigma ist a bit faster.

  1. yes, it even has the lens correction options in the K-1

  2. it covers 24x36mm, other ultratele primes have similar amount of vignetting

  3. it works good, but needs some battery capacity

  4. the DA 560mm offers focus limiter, so can be even faster to work with

[/LIST]The Pentax models are 4% more expensive than the equivalent Canon RS-80N3. So relative cheap, considering the much higher production rates of Canon.
What is cheap? How does cheap correspond to quality and and functionality?

Using an $1500 camera and thinking about an $40 wired remote (3% of the camera worth) seems strange.

Certain SD Cards Clear Buffer Faster?
Posted By angerdan
Replies: 19
Views: 782
No card which is faster than the io-bus of the camera can decrease the buffer clearing time.
There's no general connection between cards faster than 95Mb/s and faster buffer clearing.
There are so many tests that i wonder if you did research the topic before this thread.
Pentax K-3 II SD Card Write Speed Comparison of Fastest Memory Cards for the Pentax K3 II Digital Camera - Camera Memory Speed Comparison & Performance tests for SD and CF cards



No camera manufacturer gives performance details of the memory bus. Since it depends on the protocols of all involved components.
Faster cards are not slower than cards which ale less fast.
There are a lot of professional benchmarks around the world wide web, even for Pentax.
Best Memory Cards For The Pentax K-1 - Alik Griffin
Memory Cards for Cameras | Memory Card Guru



The Lexar 2000x 300Mb/s cards are old, they are from 2014. And 300Mb/s is only the maximum sequential read speed.
And the buffer clearing time depends first of the internal bus, second of the speed of the uses memory card.
Faster cards can even make the camera write less fast, when there are severeal protocols used like UHS/UHS-II.

The capacity itself doesn't make any difference to the write speed.

But the technology of the NAND memory, which goes from SLC -> MLC -> TLC -> QLC. QLC offers the lowest endurance and performance and is used in newest memory cards. Most cards use cheap TLC and high quality cards still use MLC.

Longer Telephoto Lens for the K-1

There's also the FA* 400mm 5.6 to add to you list.
300mm F*, FA* and DA* delivers mostly the same optical performance.
  1. Animals, street, ,wildlife, nature - anything that can be captured from the longer distance and looks nice as close(r) up

  2. every third time or always when there are animals expected

  3. During use nearly no difference since they all have AF

  4. When using the lens hood, difference in regular weather conditions wouldn't let you feel any difference.
    Older screw drive driven AF-lenses can be faster than SDM from DA* lenses. DA* lenses can be converted to screw drive ;)

  5. Shoulder strap like Sun Sniper or Blackrapid to have the camera ready to use. Shoulder Bag like Maxpedition Mongo Versipack or Lowepro Event Messenger 250

I'd consider less wide angle and go for an FA* 24mm 2.0 or D FA 24-70mm 2.8.
