Reasons (not) to upgrade from K-5 to K-3?

I have a K-5 with the lenses Pentax 18-135 and 55-300 and Sigma 70 mm macro and 10-20 mm f3.5.

I use the 18-135 most of the time, and the 55-300 for animals at distance, and the Sigma 70 sometimes for portraits, and the Sigma 10-20 mm rarely for landscapes.

I take pictures of landscapes, nature, people, animals, street, still life, and other things. I always use raw format and Photoshop CS6 with Adobe Camera Raw (ACR).

I am satisfied with my K-5. The only improvement that I would like to see is in light metering, where the K-5 sometimes misses,
but this is not serious because I can improve the exposure afterwards with ACR. The K-3 has better light metering.

The K-3 has better auto focus than the K-5, but for me the K-5 auto focus works just fine.

I am not sure that more pixels with the K-3 would be an advantage for me, since the 16 Mpixels of my K-5 are quite enough.

The K-3 is a little bigger and weighs more than the K-5 which is a disadvantage.

So an upgrade to the K-3 does not seem motivated to me.

Have I missed something?

If You satisfied with the K-5, was not worth change to K-3

Based on my own experience the main improvement is AF (especially in low light). If you are happy with your K-5 there is no need for an upgrade.

This is one reason DSLR sales are plummeting. Improvements are now incremental rather than dramatic. I can't imagine upgrading from my K5 unless it breaks. But this is from a photographer who is not a professional and who is unlikely to out resolve his camera.

I am pretty satisfied with the K5 as well. I would really have use of better low light af but that alone is not enough for me to consider upgrading.

There is no reason to switch if you are satisfied. There are a lot of incremental improvements over the K5, but nothing earth shattering, both are very capable cameras.

Thank you all!
It is good to see that your feelings in this matter are about the same as mine.

I have a K5 and K5iis - both good cameras, but I have traded the K5 in for a K3, mainly for the reason that you can control the camera from your smartphone which is helpful to overcome the lack of articulated screen. Otherwise, the K5 is a perfectly good camera from my point of view.

You havent missed a thing !
Stay where your at.
A switch would/might require a bit more effort at reducing noise on the K3 at ISO above about 600....... either through PP or camera settings.
I personally would say I wish the sensor was not above 20-22 MP on the K3......but it isnt.
Im eyeballing a K5II once again after getting a naughty copy last year.
If it is working for you , and its not broken....."Dont Fix It" !
Just bought the K3 and still undecided if it was the right choice for me ?

Thank you for your views!

Hi Jonah and az1895,

Thank you for your views!

I think that az1895 is right: The K-5 works fine for me and I am happy with it, so let it be!

Money is the main reason for me, why I chose the K-30 over the K-3 actually. I just didn't need half the new features on the K-3 and it was a lot more expensive. If the K-5 works for you then keep it. K-3's are getting cheaper but still they're not inexpensive and that's reason enough I think not to upgrade right now if you already have a K-5.

There's a lot to like about the K-3, but also a few things I prefer with the K-5 - such as better battery life, smaller raw files (the K-3 eats memory cards), and smaller and lighter body (not by much, but I do notice the difference). The main things I like with the K-3: dual card slots (for instant back-up when travelling), usable live view with focus peaking, and smaller focus points (more important than focusing speed for me).

As for resolution I can't see that much of a difference when using the 18-135 or 55-300. The DFA 100, however, really became a new lens with the K-3. I actually use it now

My K-3 tends to colour band a bit at high ISO, say above 12800, something my K-5 doesn't. If I could get a K-3 with the K-5 sensor... Oh, and one more thing; on the K-5 I can assign sensor shift/composition adjustment to the RAW/Fx button - on the K-3 I can't. Not a big thing but it is somewhat annoying.

Anyway, I agree with the crowd - unless you have more money than you need, stay with the trusty K-5.

And yet another thing.....
I shoot alot standing in water , camera just above water , sometimes even neck deep in water !
Im having a really hard time imagining my summer shoots with a K3 hovering above possible certain death with one wrong move !
Is it a better camera than the K30 , K5 , K5II ?
In a way....yes. But then again if it gets dunked ? Guess what I will be buying on Ebay.........a K30 , K5 , K5II.
So Im not sure exactly what my point is to you , but you wont hear me touting the advantages of the K3 at all.
Its a !%@*&# learning and understanding new settings on it (for me) , and unless you shoot Raw and PP everything there isnt much advantage in upgrading .
If you do upgrade....seriously consider the K5II ?
I might catch Pentaxian Hell for saying this......But Im having a bit of buyers remorse for ((Possibly)) making a wrong decision in purchasing the K3 . Not because it isnt a really great camera , but because it ultimately might not fit my needs , style , and technical ability.
I just learned it takes more work to get the best out of it , and that requires more time in PP .....for me anyway.
Ive had it for all of a week , and not real enthused at this point , but rather frustrated and in a take it for whats thats worth.

I don't have K-3, but have K5 and K5IIs - I can tell you that images look way sharp without the AA filter in K5IIs compare to K5.
So if you have K5IIs, I wouldn't recommend K-3, but the AA filter-less is probably worth the 'upgrade' if you think K5 images is not "sharp enough".

with the current K-3 price, it is worth the upgrade if you want to stay in APSC, I think. It essentially "upgrade" all your lenses with that AA filter-less tech.
