Yes, an imaginary number is the perfect choice for a Pentax digital FF camera. Keep the real numbers for their APS-C range.

Ouch, imaginary...

By the way if the afc tracking is good enough, afs wont even be necessary. I use afc full time with d600

Why not? We have the Ricoh Theta.

I'd be worried if they release a K-Omega ..

K-50's HDR have RAW, too. When HDE jpg done to save RAW.

Would you expect to be able to do "centre point focus then recompose" with AF-C tracking?

^_^ this is the point to explain and explain, again and again :-) ......

Yes, but you have to decouple af from half press and use only the af button.

For static objects you put subject in center, hold af button, recompose, release AF button, trip shutter. (or if you prefer you can release af before recomposing.)

For moving objects its the same except you dont release the af button while tripping shutter, so it keeps tracking as the subject moves.

If af-c is good enough, it can basically act as af-s with this technique

That would be wildlife action in my case:


Common Swift K5 with sigma 150-500.

I`ve spend 4 entire afternoons to get this common swift in flight, these animals can reach a staggering 200 Km/h and do the craziest turns. The K5 AF-c just can`t keep up and most of the time won`t even lock on. Worst of all, when finally achieving focus, it will jump and lock into the background when anything appears behind the bird (i.e. Trees, hills, bridges, etc) Improved tracking combined with color-awareness sounds like a gift from heaven to me

Absolutely agree, I have tried shooting swift more than once, and haven't got a single proper keeper. Also, thanks for picking my favourite bird for the thread illustration - nothing could be more appropriate than a swift, if the AF is anything like what it promises! I love the photo.

I was shooting snipes, common and jack, the other day: They were talking wing left, right and everywhere at close range, and I was going mad with all my failed efforts to pan and maintain focus. I really, really, really want this camera!

I haven't rechecked the spec's to find out but I was wondering if the K-3 has a 1.3x crop mode like the D7100. At around 15mp it would be a effective 2x crop factor making a 300mm show the FOV of a 600mm lens.

I have to decide what to do with my Nikon AF-S 300mm F4D because Nikon are about to update the model with a VR version (will probably cost an extra grand due to VR and diffractive "elements") that will substanially lower the value of my current one. I am thinking of either a D7100 or a K-3 for the extra "reach" using my current lens, a Sigma 120-300 Sports zoom OR a DA*300/K-3 combo. Getting that extra "reach" without degrading the image via a TC is probably the answer on a high density pixel camera. My current Pentax kit is quite limited but I still have a few lenses and do prefer the K-3 spec and build quality over a D7100.

A K-Infinity sounds cool though

I have a Jap friend who commented that on the Jap forums, there is a guy who claims he knows the Pentax engineers and has been accurate witb k3 info.
This person's comment was a cryptic 'as long as its designated K, it will be aps-c'
Might be true, might be a respin of that A mount rumor that this guy picked up on other forums.....

There's a confusion around:

• what is the mount designation
• what is designated camera series nomenclature

Pentax has, coincidentally, chosen to use K-something to designate almost all of their digital SLRs. (exception being ist*)

That was done in an attempt to convey to people that digital SLR cameras from Pentax are not some new gimmick, but that new digital cameras can use any K-mount lens ever produced without any problem. That is more than 30 years of legacy. A very strong message for a very worthy cause.

Now after some 19 DSLRs or so, it does make sense to stick to that K-nomenclature for that series of cameras, because it well defines all DSLRs done so far — they all were APS-C.

When a new FF DSLRs comes out, it may have a different camera series nomenclature, to differentiate itself from the rest in one crucial feature: the sensor size. However, it doesn't mean that a new FF camera will have an all new mount! It will be just a different series, to clearly target a specific market without unnecessary confusions. It may have some specific and different features as well: for example DA K-mount lens will work in crop mode. It will also have its own FA lenses, designed for the FF.
