K5 full review up on DP
Just read the review. First DXO now this. Those Pentax conspirators are doing a fine job.:evil: Just don't mention the sensor issues (DPR didn't)!:oops:

Night shooting
If you're going to take long exposure shots make sure the Kx can turn off any Dark Frame Noise reduction. What this essentially does is take another shot equal to the length of the exposure to 'cancel' noise from the sensor. Unfortunately that means if you take, for example, a 10 minute exposure y...

K-5 humming with LV and video
I get similar sometimes with the mirror up on my K20D in live view. I assume it's a solenoid of sorts??????? - I havent' checked it with SR off. I suppose a solenoid either clamps the sensor or allows it to float free regarding the status of SR ???

K-5 humming with LV and video
Electromagnets hold the sensor and shift it to make SR possible. If SR is off, in the K20D and later the sensor is cmaped and fixed. In the K10D it is held steady by the SR system.

K-r or K7?
As the owner of a K-10 with snapped off SR switch:?, I too am looking to upgrade to the K-R or K-7, high ISO isnt a priority nor really is weather resistance though both would be nice, what I want to know is which of these cameras can produce the best image? ( regardless of focussing speed/processin...

K-r or K7?
The K-r is definitely better than the K7. It s newer and with the latest sensor. High ISO is also better.

K-r or K7?
The K-r is definitely better than the K7. It s newer and with the latest sensor. High ISO is also better. Providing you don't get it drenched in salt water as I did with my K7. A K-r would probably not have survived the incident. As ever, it's down to actual needs and intended use. Best rega...

K-r or K7?
I don't see the need for high ISO. Back in the days of film I only shot up to 400ASA max. And why is a bigger sensor needed if you are not printing bigger than A3? It's what you do with what you have got that counts. IMHO.

Pentax K7 recommended settings for Landscape Photography
Slowly learning the K7 Sensor, it definately harder to get great Dynamic range from it than the K5 (No suprise there:lol:) but it's rewarding all the same.

How clean is clean enough K5 sensor
Having spent a lot of effort in cleaning the sensor of my K5 I've managed to remove all of the worst heavy black marks and am only left with a number of what look like feint oil stains, there were far worse oil stain marks when I started. However after this effort I'm no longer able to make a imp...

How clean is clean enough K5 sensor
I think you shouldn't have tried to clean the sensor on your camera. You should have returned it to Pentax for a replacement. Now, if you try to have it replaced, since you attempted to clean it, an overzealous employee might say you caused the damage yourself using an improper technic/product.

It still looks a bit ropey to me :cry: Do you have a 'before' and 'after' shot? How did you clean it? Was the sensor exposed to dust and were the marks there from the outset?

How clean is clean enough K5 sensor
I counted at least four more that where not marked by you. I am of the same mind as pentaxian450 and you should send the camera back. You may be charged now because of (as said) you attempted to clean it and that could be a problem in itself now. I am not doing any more than the normal sensor clean...

How clean is clean enough K5 sensor
When I last checked my sensor (which I have never attempted to clean) it had just one mark like yours. I decided that I could live with it; yours I wouldn't. My camera is going to be exchanged anyway as the cold weather and experiments with a domestic fridge and a thermometer show that the top LC...

Thanks for the response, unfortunately I deleted the images after each cleaning session, which was stupid I know. I don't think I'll have a problem with Pentax's local repair service as I've built up a good relationship with there Workshop Manager and in any case how will they know I've attempted...

A bottle of Klippies premium and I will not tell Eric :) By the way, there don't seem to be any clean ones in stock at this stage in SA. I'll have to wait :(

Servicing my DSLR
Cannot see the need for a regular service on a modern camera. Apart from a sensor clean which you can do yourself what is left to do on a modern dslr? Davex.

Servicing my DSLR
I life by the sea, I go out in foul weather, I travel to very sandy areas, and all the rest I put my equipment through. Why do you need an MOT on a modern car. I can change the oil and fill it up with petrol? It's for looking after your gear. My F2 is just 15years younger as I am. It has been thro...

K-5 Workflow workaround for stains
Hi all, Just a little (hopefully) helpful workflow solution to those who have decided to live with a stained K-5 Sensor over the Xmas period. The follwing method will basically enable all of the stains to be removed at the touch of a button in CS5 simply by recording an action to operate in ei...
