Just upgraded to a K-3 from the original k-5

I would say the low light high ISO performance is just as good as the K5 and the AF speed is the same as the k5 but It seems to be more accurate.

Just want to share a few test shot with you guys

ISO 400 to ISO3200 isn't really high ISO though.

Compare at ISO12800 and above and then you'll see the difference.

All of them are nice, but the second one is well taken!

Going above 400 always seemed a risky luxury to me... 3200 was unheard of!

And yes, great set of images. K.

I can't agree more, I hate to shoot anything above ISO400 but recently I am shooting more at night without any flash, I really wish my K-3 has the same or simalar high ISO performance as the Canon 5D mark3. I see other photographer shooting at ISO 6400 and the image is so clean can matches my K-3 ISO 800 or 1600.

Also pentax doesn't offer any super wide fast lenses which is a shame, canon and nikon users can choose to shoot with the tokina 11-16 f2.8 but for pentax we only have the sigma 10-20 f3.5

When I see others shooting with a 5d3 with the 16-35 f2.8 I always think that is time for me to jump ship. However switching switch to canon or nikon full frame is just costing far too much. And I am thinking to get a sony A7 as a 2nd body when I needed the full frame feel and high ISO performance while still shooting with pentax FA lenses.

The 14mm f/2.8 is discontinued but can be found used - I think there's one for sale here at the moment.

I have problems in low light with my K200D, but the problem is not ISO as I use bounced flash, it's that the camera can't focus

I think it very much depends on what lens you are using on your k200d, if you are using a F4 or slower lens than even the K3 cant really lock focus in low light as well.

Nice shots!

The Sigma 18-35mm f1.8 is great if you want to shoot in low light with a K3. I recently sold mine (I've bought an A7s, which gives cleaner results at ISO 6400 than my K3 did at ISO 200) but while I had the lens I was extremely impressed with it; it's as sharp wide-open at any focal length (albeit a fairly restricted range of focal lengths) as any of my other lenses at any aperture.

I am thinking of getting an A7 or A7s. I am wondering if you use an adaptor for using your pentax K mount lens on yours? If so how do you find it? I am a bit worry about how well the maunal focus will be, is the focus peaking function working well and easy to use? Please share a bit more of your experience with your A7S with me.

Many thanks
