K5 Poll
Been reading all these threads as I was seriously thinking about getting back to Pentax with a K5, might leave it for a little while though That looks suspiciously like some sort of oil, didn't Nikon users have trouble with that a little while back? Maybe over zealous lubrication of the mechani...

I don't think that's right. If you go back and look at the macro photos that DCUK took of the sensor, it clearly shows the offending blobs are actually particles of some sort. The ring is just the shadow.

is the photo I'm talking about, which clearly no one else has seen :D :D :D DCUK's caption for the image was "Please note the fine white marks are the problem area, the bubble effect seen below the marks, is out of focus reflections from the light."

The Japanese learned years ago from problems that the Germans had with sticking camera shutters to use if possible little or no lube so I think they know what they are doing :shock: :lol: Sticky greases have been available for years i.e. don't fall off, although I doubt they would use them w...

You need to be careful there are bound to be managers in Hoya who will set a deadline for which cameras are exchanged for new ones and which are sent for repair. The normal period in most businesses seems to be 1 month. There's a massive cost involved for Hoya here. If used to annoy me years...

I gave up and took mine back to the retailer this morning. I got a full refund, but only after a bit of a fight. I will now wait for a definitive response from Pentax before buying another one.

3821xxx Although the original test shots I took showed a very small single spot to one side of the frame at f/32, I just wasn't worried about it, as I never shoot smaller than f/16 and it simply wasn't a problem. The marks that have appeared are near the centre of the sensor. First shot, no...

Just done another check, and yes, I have them too. Not as bad as others, but they are there. Put it under the Sensor Scope and the sensor appears clean. Looks like it is going back. :(:(:( However, before it goes back. I am going to give it the rocket blower, just to make sure, and take an F2...

K-5 AF Speed test in "machine gun mode"
Ok, quick test of the AF speed on the K-5 this morning. Was in centre spot focus, AF-C and FPS priority. These were taken with the DA* 60-250mm f4 which isn't the fastest focusing lens in the world .. may try with the Sigma 70-200mm f2.8 another day. Not much processing, just a slight sharpening ...

K-5 AF Speed test in "machine gun mode"
Dang!! Very impressive. I could not get anything like that with the DA* 16-50. I have been unable to focus at all by the time the dog reaches me. Of course, I suppose further away subjects should focus more easily - less focusing difference from point to point. ??? I may need to try with my l...

K-5 AF Speed test in "machine gun mode"
Good stuff Mike. I need to try this myself, all I need is a dog :) So what do you think of FPS mode? Considering the speed he was running I think the camera did pretty well, especially as he was coming straight at me (which is apparently the ultimate AF test). I did try focus priority but it jus...

K-5 AF Speed test in "machine gun mode"
Having done this test Mike which mode would be best would you say for using the K-5 at an airshow? You could get away with focus priority as the planes are normally flying past and you are panning with it rather than them coming straight at you. Would probably use the 5 focus point option rather tha...

K-5 AF Speed test in "machine gun mode"
That does look pretty good Mike. Yup, probably the best Pentax to date. Not checked the lens for back/front focus yet so maybe that would help, along with a faster shutter speed.

Kr Sensor Marks?
My K-5 went back to Mifsuds yesterday who have today refunded the postage costs. They in turn have sent the camera to Johnsons to be checked over and hopefully replaced.

Let us hope we both have a camera back by Christmas!
