image stabilization performance?

Hi, new member here . Looking to get a Pentax K-r as my first Pentax dslr. Has the IS performance been improved in the K-r compared to the K-x? About how many extra stops does the IS in the K-r give you?

I don't believe it's been improved at all over the K-x. I think the official stats say 3-4 stops, but that can vary wildly.

That's a bummer. From most reviews, it seems like the K-x's IS performance isn't as strong as Olympus/Sony. Thank you though!

I've read a review where they claimed that IS in K-r is improved compared to K-x.

Brydzo, can you give us the link?
AFAIK, the SR system of Kr has up to 4 stops efficiency.
Paired with my old Canon 350D, I had a Canon 55-250IS whose stabilization efficiency were 3-4 stops. I was more than satisfied with those IS capabilities. I was able to take pictures at tele end (250mm / 400mm equivalent 35mm), with 1/60s, even 1/30s exposure time, without blurring the images.

The link is:
Test Pentax K-r - U?ytkowanie i ergonomia - Test aparatu -
Article is in Polish.

Efektywność stabilizacji wynosi bowiem około 2 EV, co jest lepszym wynikiem niż u poprzednika i tym samym nie odbiega już mocno od konkurencji.
Which translates more or less as:

The effectiveness of image stabilization is about 2EV, which is a better result than the predecessor (i.e. K-x) and consequently now it is not worse than the competition.
