Updated list of KAF4 lenses

Is there a way to reference a list, going forward, of all KAF4 lenses?

I understand there are currently two; the new version of the 55-300, and the D FA* 50/1.4.

But obviously that list will grow over time. It would be nice to be able to easily reference at any time a complete list of KAF4 lenses.

The first section under "Key incompabilities" listed here seems to be exactly what you are looking for.

There is one exception:
The Pentax K-30 can be updated with the 1.10 firmware:
Running K-50 firmware on K-30 - PentaxForums.com
Then it is as much compatible with the KAF4 lenses as the K50 or K70

..........
The Pentax Camera Lens Compatibility Chart
On this list on your second link the K-30 is in the wrong place because with firmware 1.10, which is now even used
by the "officials", in this case Ricoh - Pentax Camera Repair | Authorized Service Center | Precision Camera


This 1.10 firmware can be downloaded here: LINK

The history of firmware 1.10 is well documented here:
Running K-50 firmware on K-30 - PentaxForums.com


If ever anybody wants to go back to an older K-30 firmware, this is to be done either by using PK-Tether (the original webside is down sadly)
or by "debug menu", which is done by downloading those 2 files and then:
1. Store those 2 files on a correct formated SD-card directly next to the SDIM-file
2. SD-card into K-30 but SD-carddoor stays open
3. Switch K30 ON and one is right there in the Development Menu1:
4. 4th row: command: UDS DAT CLEAR = o.k.!
5. K-30 switched OFF, SD card removed and delete those 2 files on SD card.

I purchased my K3II back in 2017 from Adorama. The current firmware I'm running is the 1.00.

Personally I would have never thought to upgrade it at all..

I tend to have the mindset of if it isn't broke, don't fix it!

Are there any noticeable improvements in the version 1.10 firmware update?

I mainly use my camera for night photography and astro.

Pentax K-3 II Firmware v1.10 Released - Firmware Updates | PentaxForums.com

Every firmware they release says "Improved stability for general performance." shrug

There was an update for the K-3 to support the D FA 50/1.4 but not for the K-3 II shrug

Firmware 1.00 is really old.

Yes, many seem to be scared but nothing can go wrong doing a firmware update.
You just need a full LI-ION battery (or AA's, if you use those).
Pentax cameras never allow firmware updates with bad batteries! So no risk.
The rest is automatic. Just don't switch your camera off during update, that would be the only possible mistake.

The improvements are described in the thread! One is double ISO. I don't need it but some like it.
The other is PLM lenses can be used and the K30 works faster and is more stable!

But we're talking about the K30 and firmware 1.10, not the K3II
I was mentioning the K30 firmware but you wrote about the K3 so your are correct of course!

I feel like the manufacturer needs to write that.. Similar to how when you see an orthopedic doctor; and they write a comment to describe no significant changes to whatever they are inspecting..

Without actually describing the significance; It's difficult for me to jump on board..

Yeah, firmware is really old.. But so is the camera, considering a new camera pops out every 6 months or so..

Same analogy that there are still classic muscle cars driving around, still looking sexy as ever even knowing they're running on old outdated tech! It's no Tesla, but it gets me from point A to B...

Oh.... Am I in the wrong thread?
Has google search query led me astray? ...ughh... This is a bit awkward 😆

Well.... Um.... I guess my only gripe is if my camera has a power saving mode and it turns off after 5 minutes of inactivity... Would that include updating thw firmware?

Is the camera smart enough to realize that there's an update in progress? (Not to auto-shutoff?)

Mmmm.... Is there anything changed with the astrotracer or pixel-shift performances? That's all I really care about...

And considering I only use specific lenses.. And dont have or plan on getting whatever the update is for; I could carry on my very merry way with the 1.00 firmware?

Do you think there'll be another firmware update in future? Or is service to this model discontinued/no longer supported by RICOH-Canada Inc.?

TBH, in my limited experience, RICOH has a poor record on updating the f/w for "older" models that are now out of production .

OTOH, I've updated the f/w on all my Pentax bodies over the last 11+ yrs with no real problems, and the hacked K-50 f/w for the K-30 worked very well and allowed me to use the 55-300 PLM (one of the best and most useful lenses I have ever bought ) on that body before I got the K-70.

It was my fault, I brougth in the K30 1.10 firmware but of course you do have the K3 and thus firmware 1.00.

Ricoh always mentions the benefits off the newer firmware! It is clearly statet on the downloadpage!

No changes to any function!


Auto-shut-off is deactivated during the firmware update!


There is really no risk at all!

So have a frest charged battery ready and download the firmware from here:
Latest PENTAX K-3? Firmware Update : Software Downloads | RICOH IMAGING
and follow the steps.

Nothing, really nothing can go wrong.

That, of course, means that the firmware upgrade improves your tripod!
