Upgrade from K-5 to K-3

My wife and I both own a K-5. We did this so we can share lenses and camera knowledge. Our hobby is go out on weekends and take photos of birds.

We have been contemplating trading-in one of the K-5's on Adorama for a K-3. Obviously adding cash as well.

For bird photography are we going to get a much better picture with the K-3 assuming nothing else changes in our ability or lens complement. What is likely to improve? Better AF and IQ are our hope. The old eyes are 100% dependent on AF so any improvement here would be very helpful.

Or would a better idea just be to get additional longer lenses like a Sigma 150-500mm and a pair of the 1.4 teleconvertors being bandied about recently.

Comments appreciated.

The K-3 is an improvement in literally every area- performance, video, image quality, AF, viewfinder, screen, you name it. See our review for the details:
Pentax K-3 Review - Introduction - PentaxForums.com

The biggest improvement for me has been the new metering system, which results in spot-on white balance at night. And the only downside IMO, and it's a small one, is that the 24Mp files mean much bigger files/RAWs, so they will take a bit longer to process on your PC.

By the way, don't trade in your camera. B&H won't pay you very much ($255) and you'll get a much better price ($400-500) by selling directly to another one of our members:

For birding the K3 will provide much better AF and picture cropping ability given the 24 MP. If you have the original K5 then the AF will be much improved; if you have the K5II or IIs, AF is subtly improved.

And it must be said that the K-3 shines if you give it stellar lenses - the better the lens, the better your photos will be.

You are a great couple! Now get yourself a K-3.

Adam is right about trading in your camera. You should try Market Place first. To add K-3 kicks every other camera in the right place for action photography.

Cheers!

The K5 and K3 operate basically the same, just get one K3 and you can take turns using it. Keep both K5's since you can't get much for them right now. If you have extra cash, put it in better glass. You may find that you like the K5 better, who knows? I love my K5 II and have no desire to get a K3 for a while.

I've found that the smaller AF points allows me to better focus on a bird surrounded by branches. With the K-5, my focus often ended up on the nearest branch and not on the bird. The K-3 also focuses more accurately in lower light (i.e., shade).

I think you would be very happy with the performance of the K-3.

Cheers,
Lou

In my family, I'm the bird guy...and I really like the K-3, faster more decisive focus, more room to crop, although the extra 1000 pixels wide isn't as dramatic as you might think. My A-400 is prone to CA and purple fringing, and it's definitely worse on the K-3 with cropped images and cheaper lens like this if they do have CA and Purple fringing issues, those issues will be magnified by the TC... when the 1.4 converter comes out, I'll probably start using that with the 60-250 or possibly buy an DA* 300 ƒ4. I wouldn't plan on using any lens with a TC, unless it's a star quality lens, from which ever manufacturer.

If you haven't checked out the 300 plus lens club, you might want to give it a look. Defintiely the place for discussing lon lens options.

I heard that the high ISO noise and DR from K 3 is actually a little worse than K 5 & K 5 II/S not just DXO reports it( And I don't trust them) but few reviewers online says so too. Other than that the K 3 should be better than the K5 in every other ways like Adam have mentioned.

I don't know which lenses you own, but I think the K-3 should be the next option after a good lens.
Maybe it is me, but I am in a lens buying period

Pulled the trigger and ordered a K-3 today. Should be here in 2-3 days. I'm keeping my K-5.
