Tamron 28-89mm f3.5/5.6 Pentax AF
Hi Spamcan, I think the plastic on the lens bayonet fitting will be quite durable, a lot of the budget lenses from the likes of Canon and Nikon (Pentax too maybe?) had plastic camera bayonets. They are only a major concern with big, large heavy lenses. The plastic mounts don't have the streng...

K10d or K100d for novice
...and poorer low-light performance if that's true, would be downsides for me. Pete, it's swings and roundabouts ;) The 6Mp SLRs cover ISO 200 - 3200. The 10Mp covers ISO 100-1600. The 10Mp noise at ISO1600 is different to the 6Mp. From what I've seen (as I have 3 Pentax DSLRs) the 10Mp has far...

Cleaned the sensor of my K10D
Hello Just cleaned my mirror, focusing screen and sensor with Visible Dust VDformula+ and Visible Dust Sensorclean. It works perfect, everything is clean again. However cleaning the sensor it tilted when the wip reached the right side (seen from the frontside) the sensor seemed to tilt down. ...

Cleaned the sensor of my K10D
The first rule of SLRs is never, ever clean the mirror. The mechanism is critical to the correct focusing and is easily put out of adjustment. In normal use, the mirror should not need to be cleaned anyway, even after many years of use. Any specks will have no effect on the image. The same applie...

Cleaned the sensor of my K10D
oops I am another one. I used a lens micro-fibre cloth to clean both the mirror and the focussing screen. Giotto blower on the rest. I do have a very clean K10D now, I just am worried what you write John and all the rules I have broken! My problem was, my camera had to go back to have the mother-...

Cleaned the sensor of my K10D
As John so rightly says never ever touch the mirror. On normal mirrors the fairly soft and easily damaged silver coating is behind the glass but in SLRs, to prevent unwanted double images, it is on top. Even a brush can leave an indelible mark

Cleaned the sensor of my K10D
I think nowdays there is a protective coating over the silver.

Cleaned the sensor of my K10D
Thanks guys, I will clean with even more care now. To be honest, this is only the second time I have needed to clean the K10D in 8 months - and I only have prime lenses so I change quite frequently.

Glad I cleaned it all, everything is back to normal again.

K20D TTL flash capabilities - does it have any?
Subject says it all really, but I'm guessing it doesn't. I would just ask those privileged persons who have had a look at the new camera to let us know if Pentax have re-enabled TTL flash control. Inside the mirror box there will be a rearward facing sensor at about (or exactly) 45 degrees to ...

I can't believe this is normal, so would much appreciate your advice. It's perfectly normal, as is alarmed new K10D owners asking about it :) Note to the not-so-new... Do we yet have a definitive answer as to whether it's the sensor shifting or the orientation sensor? I keep imagining that ...

I too found the dull thunk to be alarming as well, so much so I was about to return it to my local branch of Jessops. Even when the camera is switched on, I was still getting the knocking. One way to put your mind at ease is to dial in a long exposure time, of 30 secs and rock your camera from horiz...

One way to put your mind at ease is to dial in a long exposure time, of 30 secs and rock your camera from horizontal to vertical, you will find there is no noise then. I just tried this... during a 10s exposure, rocked the camera from portrait one way to portrait the other. Got the same slide thunk...

I asked a Pentax tech. in Canada, and he said it is indeed the sensor moving when the power is off because the electro-magnets aren't holding it anymore. :)

I asked a Pentax tech. in Canada, and he said it is indeed the sensor moving when the power is off because the electro-magnets aren't holding it anymore. :) This is an example of how hard it is to get a definitive answer. Power off? I don't have to have my camera switched off to get the noise, a...

K10 odd movement
As I said last night, I sent a quick e-mail off to Pentax UK about the slide-thunk issue. My e-mail read: I recently purchased a Pentax K10D. My question is; When I rock the camera from the vertical, through 180 degrees, to the vertical, I can hear and feel a thunk. Can you explain what this?...

The fact is that if the sensor is making the "thunk sound" as it's rotated (sensor falling due to gravity) whilst an exposure is being made (or the camera is in cleaning mode) then it is faulty. You say this is 'fact', but do you have an authority to cite for it? I've now tested two K10...

You say this is 'fact', but do you have an authority to cite for it? I've now tested two K10Ds, bought at different times and places, both apparently functioning normally, and they both exhibit the thunk during long exposures, but only if SR is on. I don't need authority just common sense. That n...

Right, I'm pretty sure I know what's going on now, at least for my K10D. I've taken the lens off and actually watched what's happening during long exposures, with SR on and off. First with SR on: The mirror pops up, and for small camera movements, you can see the sensor moving around as it ...
