GX10 to K30

I have a 3 year old GX10 twin lens kit. I had planned to upgrade to a refurbished k7. But now the K30 has come down i am thinking about a K30.
If i trade in the gx10 body for a k30, will the kit samsung 18 - 55 Sa and 55 -200 Da lenses produce better results with the k30. Many of my shots are indoor shots, of mykids swimming in competitions. I need a fast shutter and minimal noise, in oftain poor light. The Gx 10 struggles with this, will the k30 be better, of should i wait for a k7 refurb that come along from time to time from pentax.

advise and thoughts please

If you want high ISO with low noise, I'd choose the K-30 over the K7 in a heartbeat.

I went from kx to k7. Love it expect for the ISO thing to upgrade to k5 second hand. I'd recommend trying k5and k30 tosee which youprefer.

I agree with this 100%

.. for sure

As a GX10 and now K5/KR owner, I would suggest you take a look at this thread if you have not already done so:

I had one of the original K10`s which is pretty much the same as the GX10.

If you test drove a car 10 years ago and repeated the drive again in a new model the difference would amaze. Same with a K30 over a GX10.

I would suggest the WR lenses though if you use it in warm damp atmospheres.
