Quick K-5 Firmware Question

Apologies if this has been asked before.
My K-5 still has firmware version 1.01, the version it came with. I wish to improve the K-5's low light auto focus performance which was done in V1.03. I think the current version is V1.13 but from what I can see following versions improved GPS performance of which I have no interest. Is it always worth upgrading to the latest firmware or should I install V1.03 if this is still available?

Quite often an update can make other "improvements" that can be kept quiet, it's wise to update.

V1.03 is the one I'm on...

The UK Pentax site also has firmware listed for the K5 Limited Silver but I don't know what thats about (as I had assumed the silver body had the same camera inside?)

I feel that it's always worthwhile upgrading firmware to the most current version. These updates are designed to eliminate any "faults" that were inherent in the original firmware, much like the updates that Microsoft, etc release to patch security flaws, improve program speed, memory issues, etc.

Generally, these firmware upgrades are cumulative, so the latest version will not only have GPS performance improvements, but the other firmware updates too.

I think the latest updates include all previous updates

Thanks everyone. Will upgrade firmware tonight to latest version.

I think it would be wise, after an update is released, to wait and let other people do the update first and see what they think. I have had quite often problem with software updates, when the update introduces new bugs. maybe I am to carefull, but I had problems before.
Of course if everyone would do the above, no updates would ever be downloaded. This is the negative part.

I'll let you know. I updated last night...!!

Wise words. Updates can and do introduce new problems from time to time. I'm still on 1.03. Simply because the later versions are for compatibility with the GPS attachment which I don't have. Everything works so pointless updating

I always update to the latest firmware simply because we are not always told the whole truth. Whilst a list of changes usually accompanies an update, there are sometimes other changes in an update that are not listed.

Such as?

Here's one for the Q.

•Correspond to [Adapter Q for K-mount Lenses]. How to input focal length Click here
•Correspond to [PENTAX-06 TELEPHOTO ZOOM]
•Improved stability for general performance.
*Contents of [Version 1.01] will be also updated.

No mention of the addition of focus peaking

I can't remember exactly which model or firmware version, but some users noticed an increase in AF performance after a firmware upgrade to their cameras where AF performance was not listed in the improvements.

It's not unheard of for manufacturers to slip in corrections to software/firmware without telling us what the correction is or what it does. Adobe Lightroom updates always have the catchall phrase in their software updates, something like " . . . includes other corrections and bug fixes not listed above" or words to that effect.

Additions to the lens and SDHC cards databases are two items
that don't get listed.
