Shutter Blur: K7/K5?

My take on this is that the argument is a fat steaming pile of poo.
Anyway, the K5 is a completely different shutter from the K7, so even if the K7 had a shutter blur problem (I'm not convinced it has one based on a few tens of thousands of exposures), there is no reason to presume the K5 would share a similar problem.

i have some shutter blur on my K7...just thinking....what if a battery grip was added with the K7 would the shutter blur simply go away or lessen to an extent?

Never had the issue with my K7.I did a set up and tried at the various shutter speed and could not see a problem.So could be isolated cases.My advice get the K5,if there was an issue,you bet the engineers licked it.
I got my K5 yesterday,......JOY !!!! ....

I used to have shutter blur issue with my k7. As I can consistently reproduce it, it was easy to get it fixed under warranty.

Now its all good.

I just got wind of the K7 shutter blur issue this week. I've spent most of the week reading all the posts, reports and white papers about this issue.

And all this time prior, I've been suspicious of my DA*16-50 for so many 'unsatisfatory' wide angle shots. Lots of throw aways due to lack of sharpness and detail. In stark contrast, the DA*50-135 and FA*200 consistantly deliever very sharp images from my K7. Throw-aways with these lenses are rarely due to lack of crystal clear detail. So until now, I was not suspicious of the K7 at all.

Until I stumbled across the K7 shutter blur issue this week, I had actually been thinking about replacing my DA*16-50 with a FA*28-70 [legendary for it's sharpness]. I am now going to give the DA*16-50 some more time to impress me by steering clear of the K7 shutter-blur zone [1/125~1/80sec]. I am primarily an AV mode shooter, but I'll now be paying much closer attention to the shutter speeds chosen by the K7 of the good & bad shots out of the 16-50, to see if the throw-away wide angle shots fall in the K7 shutter blur range.
