C mount was mentioned too.
I am sure if the adapter provides the correct focal plane for the lens type (so a rather large adapter for K-mount) I am sure that it will work. And as a plus, the sensor will only use the very centre of the lens, so in theory should be as sharp as a tack without any sharpness fall off whatsoever.

But like you say, we shall see.

One interesting thought though about the Q.
Pentax have said that initially they are not making any adapters for other lenses, but "Are considering it".

Now the sensor has a crop ratio of 5.46 over a 35mm, so taking that into account, imagine using one of the Sigma "Bigmas", therefore the 170-500, 150-500 or the 50-500. You would get an effective focal length of 2730mm! and with a x2 converter 5460mm!!!!!!!!
Perfect for birding would you say?

Actually if you are really flush and get the Sigma 300-800 you could get a 4368mm and with the x2 and 8736mm!!!

If Pentax do make a converter for the K-mount, I might be very interested.......

Good for you Reso. I was too late to respond, but I do have this lens, and its a cracker. And for £70 a bargain too (second hand prices seem to hover around the £120 mark)

Its also a stunning Portrait lens too, and very sharp.

Enjoy.

Most used - DA*50-135mm
Least used - Osawa 200mm F4 - Its not a bad lens, but manual and only used it very occasionally

I use fast lenses for two reasons.

1. Creative use of DOF.

2. On the whole the vast majority of lenses only get sharp (or the sweet spot) when stopped down a couple of F-stops. So, the faster the lens, the faster the aperture for that sweet spot. So you could go back to point 1. Fast aperture, shallow DOF, pin sharp! Love it!

I have voted not sure. Nothing to do with the takeover, more to do with financies.

I still want the Limiteds, but they are a desire rather than a need at the moment.

I know what you mean about the 28mm. Perfect focal length, but if the Sigma F1.8(which would be a nice aperture) is anything to go by, a big lens.

However I do like my DA35 F2.4. Cheap, plastic, and yet so sharp with great Bokeh. Its a great compromise focal length lens.

There is a K-mount adapter for micro 4/3rds cameras. However you lose camera control of the lens, making it fully manual only.
As DA lenses don't have an aperture ring, it will mean that these lenses will be stopped down in operation
But with any k-mount lens with the ring (K, M, A, F, FA) can be used with the adapter.

Well done Simon, lovely photo.

I would look at the Pentax GX200. 24-72 eqv lens, RAW ability, fast lens, well built.

Oh, hold on, its called a Ricoh GX200..........

Seriously
The Pentax i-10 is not the best compact in the world, yet its more than adequate. But the way it looks is soo seductive that you actually enjoy using it. I know, I have one.
