K-S2 & MX-1
The biggest clunk and bump on mine is the noisy autofocus! - that aspect of the new kit lens really appeals to me. A camera at its heart is an image capture device. Pinhole cameras didn't make any noise and you didn't look through them. All cameras capture light, and make a saved image out of...

You're saying it has ' mechanical' sensor shake reduction in video? ?? Pentax might be getting at least one more customer soon!:D Can we get this verified folks, if so it signifies an excellent step back !

K-S2 & MX-1
I'm still happy with the K7 SR, both for video and stills. I do mostly use a hotshoe MIC and have never heard any sensor shake noises on an audio track. I recently got my first long zoom for Pentax, and I find I can shoot perfectly sharply at 300mm with a 1/80th sec time value ... Very happy wit...

Still the stupid shakes at Yes, but you have to be looking for the wobble, rather than it being like a sudden 6.9 earthquake occurred.. I've had footage ruined by this system on the K-30, where the software thought the scene was moving. If sensor based stabilisation was being utilised, the senso...

How is that relevant to the topic? Quite. Sony have stabilised video by moving a larger FF sensor during video recording. Olympus have stabilised video by moving a smaller m4/3 sensor during video recording. Pentax have been moving sensors since the K100d era, and stabilised video by moving a...

Thank you for sharing this interesting article! Having owned and used a Sigma DP2 Merrill for about half a year, I must say it sounds very promising that Ricoh Pentax are researching into a "foveon-like" sensor technology. If they manage to produce a sensor that records pure RGB instead of the more ...

Not again ... Are you able to formulate a short summary of the most important points in the patent document:D:lol: Certainly : It proposes two separate systems for moving the sensor, one electromagnetic for shake compensation and the other piezoelectric for fast fine pixel-scale adjustment. Plu...

used a Sigma DP2 Merrill for about half a year, I must say it sounds very promising that Ricoh Pentax are researching into a "foveon-like" sensor technology. If they manage to produce a sensor that records pure RGB instead of the more common Bayer "guess-work", and implement it into the new FF, it w...

Sigma cameras are outside the remit of Pentax User, but for the record I have reviewed their fixed lens cameras and was not impressed, but there we are. The 16MP sensor Pentax cameras are actually quite hard to beat in many ways.

I think Pentax are to be applauded with their new pixel shift system in the K3 MkII, it should really elevate the image quality of the camera in situations where it's possible to use the feature. Studio work should benefit as well as the odd landscape on a very still day. It's just a shame it take...

I think you misinterpreted what I was trying to suggest, i.e. a 700km shift on a "Sun-sized body" sensor to be equivalent to a 1 pixel shift on the K-3II sensor (sort of, anyway!) :D

Your shutter time value would be replicated 4 times, so the electronic shutter would only save you a small proportion of the time the sensor was exposed. No one is going to stop you hand holding if you really want too, but assuming shutter speed is now x4 in total duration, and only one pixel of...

Pentax K3 now priced below most of the Pentax K-S2's
As much as it's nice to see the add ons for the K-S2 (wifi, flippy screen), and I'm glad Pentax now offers the option for a product like the K-S2, for the money the K-3 is quite a step above. IF Pentax/Ricoh restored mechanical sensor stabilisation during video, and everyone was suitably convince...

Initial thought on new K3
I bought a third party grip for my K10, used it once then discarded it. The slight benefit in handling was far outweighed by the increased bulk. An already heavy camera was made even heavier. Anything which puts me off taking/carrying/using a camera has to be a bad idea. Maybe something like one ...

K3 receives unsolicited compliment
Someone recently asked me how we got our backgrounds fuzzy. I thought that was an excellent question, as it showed they'd seen and identified something they liked but didn't know how to reproduce. Led to a conversation on Aperture/Av settings and how to maximise the capabilities of the gear they h...

Right lets get the rumour mill rollin... K3 II
I'd expect just the obvious floppy screen and wifi/nfc, along with a sensor shift high res mode.
