buying a k3

I have a k5. is if better to buy the k3 for cropping and sell the k5. I know the battery for the k5 will work on the k3. I saw the k3 with accessories for 650 dollars.

Cropping is only possible as far as a long string of conditions are met.
There's lens quality, ISO sensitivity, actual exposure (for SNR) and shutter speed.
In short, light quality and quantity and user technique.
Don't count on it 100%

The image files are larger and that leaves you more room to crop and still get a good printable image. But as noted above there are lots of factors besides the mega-pixels that are involved.

The are a lot of reasons to get a k-3, 24 MP is one but the AF is better, the camera is more responsive and in my opinion just better built. I used the k-5 for years and still have a k-5IIs as my backup body but the k-3 is on another level.

But don't expect miracles just because you can crop in, good glass is almost always going to be a bigger improvement than a new body.

I agree with the above posters. You will gain some room for cropping if you have good glass - and a good, sturdy tripod.

There are some things I like better with the K-5 - it has ISO 80, has a bit better dynamic range, it weighs a bit less, and it lasts longer per battery charge. For most everything else I like the K-3 better.

If cropping into and then enlarging is your plan, as others have said... more megapixels only plays a small role. Lens resolution is the real factor, IMO.

On my k30, when using my K 28mm f/3.5 lens, I could easily increase the image print size by about 33% without a care. So now, using my K3, it's even better.

As far as I know, there is nothing to lose but a lot to gain upgrading from a k-5 to k-3.

If you live in the USofA and are buying a new K-3, don't forget to acquire an extended warranty. You have 30 days to purchase after you buy the K-3...

Pentax 2-Year Extended Warranty for Pentax and Ricoh 85716 B&H

...and you need not buy the warranty from the camera's seller, either.

I used the extended warranty once with my K20D, then twice with my K-5 and saved a ton... Fortunately, so far, my 2yo K-3 has had no problems.

Highly recommended... M
Good reminder! Very easy to forget getting this when you purchase a new camera! I made a note to include this when I purchase the K3!

Thanks for a timely reminder!

You will lose some $ for sure. And size of image will be bigger (but I would agree size is not that important nowadays).

I guess perhaps only in my case, I both them both new (k-5 at USD 720 and k-3 at 620) different times, therefore, IMHO, k-3 is cheaper.

You are right... but I don't think that I use ISO 80, not even once...

What doesn't the K5 do that you need/want it to do? If you want to crop more, maybe you need a longer lens.
