Why a K-5
[quote:3496ace15f="cbrog"]Just be aware that the K5 is a relatively new camera and, apart from the unfortunate sensor splodges, does not yet seem to have been fully sorted in the way that perhaps the K20 has. Given Pentax's present situation I wonder if it will ever be. I'm not at all sure there's a...

Why a K-5
You need good lenses to get the best from any make of camera Canon don't make any L badged EF-S lenses, but you would be hard pushed to find a better crop sensor lens from any manufacturer as good as their 17-55mm f/2.8 IS (10-22mm is none too shabby either)

Why a K-5
Nothing like an external review of the sensor to give you confidence in your choice..... http://www.dxomark.com/index.php/Publications/DxOMark-Reviews/DxOMark-review-for-the-Pentax-K5 It made up my mind, compare it to others in the price range....impressive!

K 5
What are peoples thoughts on the K 5 as I have a K 7, that is a problem. Am onto my third K 7 as my second K 7 has trouble with the second sensor that has been installed.My camera store has offered to swap it for a new K 7 that they have in stock at no charge. What are Pentax K 5 users views on pa...

K 5
The K-7 had a lot less problems than the K-5 which (apart from the sensor) is quite strange considering they share the same body. Would I go back to a K-7 .. absolutely Would I sell my K-5 to go back to a K-7 ... no chance.

K5 amplified noise in live view
The K-5 has moving parts which need to operate in live view. The mirror actuator needs to keep the mirror up, that makes a little noise. The SR mechanism has to move the sensor to keep it steady, that also makes some noise. Noise in live-view is normal as far as I can tell.

K-5 video hotspots work around (fixed)
Hi, I noticed a couple of moderately large sensor spots (green and red on my 1080p video in low light, these are not high iso noise, these are like dead pixals with a slight halo around them, the green is brighter, i have 2 bright ones and one faint one, on the left hand side in this pic. ...

K-5 video hotspots work around (fixed)
I cannot see any possible correlation with sensor hot spots and the swapping of lenses while powered on. As far as I know, lenses have nothing do do with hot spots. I would certainly not recommend this practice no matter the perceived results you saw. Also, can you explain what you mean about li...

K-5 video hotspots work around (fixed)
I cannot see any possible correlation with sensor hot spots and the swapping of lenses while powered on. Swapping lens with the power on has nothing to do with hot spot, but since the sensor is electrically charge, it increases the chance of dust being attracted inside the camera and, eventually, ma...

K-5 video hotspots work around (fixed)
thankyou for your comments i only tested the idea once so i'm glad i read this before i tried agin. but it does work, the spots go once this process is done, i admit it feels wrong taking the lens off while the camera is on, and i didn't know about the charged sensor when powered. live view d...

K-5 video hotspots work around (fixed)
As far as I am aware, dust cannot sit directly on the sensor due to the filter. Any dust in front of the sensor will only block light and therefore will result in a dark spot. Only leakage currents can cause 'sparkles' (or hot pixels). I'm no expert, so I may be proven wrong about this.

Pixel mapping is available on the cameras and the "hot pixels" can be mapped out of existence. Dust is dark specks and these lie on the low pass filter that covers the sensor.

Will K5 price be driven down by new mirrorless?
The prices should not affect one another. The K5 and K-01 are two very different cameras, having only the sensor in common. It will be interesting to see how the K-01 IQ looks with it's new M imaging engine. It just may turn out to be the defacto platform for the Ltd's? Best regards

I've noticed a couple of comments about the sensor, bu Pentax did say that it was a new sensor.

Will K5 price be driven down by new mirrorless?
Perhaps someone can explain why the PK mount is the problem with producing a thin body? I can see that the lenses need additional distance from the sensor, but that could be dealt with using an extension tube with a k-mount - something that Pentax could then also sell to existing DSLR users. If ...
