Hello all, as some already know my gx20 is faulty. No news from samsung at all. Sobdebateing on buying a new k7, how is the autofocus speed, will I notice huge difference if using hsm lens on this k7 body. How much of an overall improvment is it on the k20d. Will be shopping for it over the weekend. Thanks all

I don't own either camera but from what I've read on here it would seem that the K-7 is faster than the K20D but that the difference isn't a night-and-day one.

I have both and the K7 is a bit faster but not much, I don't have any HSM lenses so can't give you a comparison but it does hunt a bit on long lenses,

A good answer is 'meh, whatever'

A better answer is, a bit yes, low light performance greatly improved.

Edit: either way, you'll love it!

If I understood correctly the OP is asking about AF speed.
I am definitely staying out of this discussion

Jack,
This is probably down to smaller apertures. All AF systems prefer lots of light.

Best regards

I'm not sure it's very much faster - perhaps it doesn't hunt as much. The AF speed isn't going to set the world on fire, but it's perfectly acceptable. Screw-focus lenses seem a bit snappier - the motor may be a bit beefier.

Low light handling definitely improved. AWB definitely improved, especially in tungsten and low light.
Very happy with mine

I am committed to not giving George any reason to pounce on me, right George?

Carl, jokes aside now , from the little I know the K7 is definitely an improvement over the K20. The AF system is different also compared to the K20. One thing that I felt handling the K7 is that it has an improved metering. The overall feel totally different. Aesthetically a completely different beast too, unless you are into liking bigger bodies or chunkier ones then you will be disappointed. I loved the fantastic handling and feel of the body in my hands. I did feel it to be slightly faster compared to the K20 with the DA* lenses but this is where the arguments become contentious. I attached the DA*300 on it and it was fabulous, then fitted the DA*60-250mm and couldn't get a fast enough AF. Unlocker knows all about it, he is the expert on the K7 vs K20 AF speed.
And just as Mattmatic commented Screw-focus lenses are definitely faster on the K7

Now I better shut up or else I risk hearing a sarcastic comment from someone asking me why didn't I buy one, and that could be the road to more arguments.

Surely screw-mounted lenses would require an M42 adaptor and not have auto-focus?
If you can't say something nice about Pentax, you won't say anything at all.

Apparently.

oops Robbie, my mistake describing the lenses, just corrected it.
The reference pointing to Mattmatic comment above should have noted what I meant
Thanks for that
