Full Frame (again)
I do think 'full frame' has a now artificial mythicalness about it. Originally technology wise it was difficult to manufacture a sensor the same physical size as the 35mm film format. We are leaps and bounds ahead of where we were initially now, so it should no longer be so unobtainable. I real...

Full Frame (again)
Maybe Pentax will do with the K-3 what they did with the Q10 - just put a larger sensor in. Not quite that simple I know but it would make for a very compact 24x36mm DSLR. Has anyone tried out the new HD Limited lenses to see if they are actually full frame? If they were, then maybe HD is the des...

Imaging Resource says Although the Pentax K-30's incorporates a sensor shift-type image stabilization system, this is disabled during video recording, in favor of what Pentax calls 'Movie SR'; in essence, digital image stabilization. Unlike a mechanical system, this allows completely silent oper...

That 'Movie SR' sounds a bit like computer software type stabilising functions. I use Sony Vegas Platinum and tried the stabiliser function, but wasn't happy with it due to the significant crop it applies - you have no control over this or the amount of stabilising (although I guess you might in the...

I've not heard enough at all on the K3 video. Is it sensor based (ie real) stabilisation. Are the bit rates good/comparable with the competition out of the box at least? Can the AF work during video recording? Can you turn on focus peaking during video? Yes, premiere pro has a warp stabil...

I have not been aware of sensor noise being recorded, although I often use a hotshoe mic. The K30 system sounds like a backwards step. There is an occasional 'chirk' as the SR moves the sensor. Nothing objectionable. I agree, the K30 system isn't as good, as far as movie SR is concerned. (It's bette...

I have shot loads of footage on my K-30 and my GF's K01, some even for professional work. They are essentially the same apart from the latter has focus peaking and a mic in port. I'll dig up some of the clips from online. Bottom line is that the video quality is extremely soft and if you set the cus...

Over the weekend I took a short video clip on the K-S1 (a rare event for me!) Unfortunately the video oscillates up and down. On checking the camera settings I discovered sensor stabilization was turned on by default so I have now turned this feature off. But Richard is a devotee of this so calle...

That sounds like a fault. As we know, the K-S1 doesn't use sensor-shift for SR, only software SR (MovieSR) . Thing is, the sensor plate is still powered on even with SR switched off in order to hold the sensor in place, otherwise it slops around inside the body. Thanks for that. Well I do not know...

That's fine, similar to what I got on my K-5. I must say I hadn't realised the extent its got wrecked in the recent models. Arriving a bit late to this conversation, but Steve's got it covered. Every Pentax camera since the K-5ii models has had a software attempt at video stabilisation called 'Mov...

Turning it off is an option, in fact it's the only option if you want to avoid warping of your footage. You can then reapply some stabilisation in post production, which at least you get a lot of fine tuning control over, rather than no control via Movie SR. Obviously the more proactive you are at...

I note they say, "So far the sensor shift is disabled in movie mode in order not to record mechanical noise." So presumably the capability has simply been turned off, so should be simple to flick the firmware bit to turn it back on. It leads to the question though as to why they did this and not k...

I think user technique will be significant .... If you support the camera well and make controlled, smooth steady movements, then the sensor SR is superb ...(it is on my K7 anyway). It can look like you're using a professional film rig, racks and rails etc, especially at wide angles. The real com...

.... I will however take Nigel to task (slightly!) on his assertion that Pentax don't listen. They have actually introduced almost everything members of this forum have ever asked for over the past 10 years. Video is the last bastion of the Things to Do list, probably quite rightly as it is a fairl...

I don't remember seeing many complaints from K7 and K5 users about sensor noise on their videos, so why it was seen by Ricoh as an issue is unclear .... ? Or was it just magazine and YouTube reviewers they were worried about ......? Nailed it... I still have a number of video files from my K-7 wh...
