Thank you.

Yea, I might have done with lighting the background a little to help with that but since the image is live, and has already done so well for me I don't really want to go back and do another edit but something for me to watch out for in the future

Thank you and no problem, I always like to share

I know I don't post in here that often but I got an article published on SLRlounge.com, a BTS look into how I shot the noble family image with my k5.
Feel free to check it out, and if their is any questions please let me know.

That would be great, as the MovieSR (the silent version) would have its uses (ie if you had no external mic).

All it would take for pentax to have great dslr video would be an option to people would be to add manual mode to the k5's and let the auto horizon work too (as this would help keep the footage lvl and dampen rotational shake).

As for the k-01 and k30, k50 allow you to switch into sensor stabilization and let you pick AVI or higher bitrates for movie recording.

I bet pentax would have sold a lot of units for people doing video, who wouldn't want a weather sealed camera that had nice video and stabilized any lens fitted to it (like fast primes).. and it would be the only system to be able to stabilize the new sigma 18-35 f1.8 which would be a great video lens.

If it was me, Id be kicking myself in the head for not doing software updates that could potentially sell quite a few units and also make exciting customers happy, they have probably lost quite a bit of revenue and could have had a great video following just for updating software.. its silly.

As it is.. the new em-1 from Olympus seems like a good bet, better stabilization, EVF similar in size to some FF cameras, can use many more lens including focal reducers like the metabones and has f0.95 prime lens available and lots of nice first party lens from both panasonic and Olympus themselves.

I really do love my pentax stuff, but its getting ever more tempting to switch over.. I'm hoping for something wonderful as a proper k5 replacement

They all have electronic shutters, the tax is related to camera's that can record 30mins+ of video in one take.

The black magic pocket camera is only 1080p and an even smaller sensor than m4/3 (even though it uses the m4/3 mount) it will no doublt be a great camera and record much better detail than most dslr's although the recent canon RAW video hack will have an impact on there sales but there are people wanting to use the new sigma 18-35 f1.8 with a speed booster on the black magic. There cinema camera records in 2.2k? which isn't much more than 1080p but leaves room for cropping later if you wish.

I have no doubt that things will move to 4k but giving the file sizes involved I think for a lot of people 1080p will still be the sweet spot for years to come, also given that it will take a while for 4k tv's to become the norm, hell I still know people who watch standard def programs.

It's a shame there has been no hacks for pentax stuff, I think the best quality of video from the current crop of pentax camera's is still with the k5 as its AVI can record around 100 Mbit/s but it comes with the limitations like no manual mode, over heating, crazy file sizes.

If Ricoh/Pentax were to give us a firmware update for the k5 to get manual controls and let the auto horizion feature work in video I would be super happy and we would have a great video dslr.

As long as you record under 30mins there is no EU video tax, hence why lots of cameras are limted to 29m.

I hacked my gf1 to remove this limit and can record video till I run out of space or battery .

Shooting short movie's the video limit even on the k5 isn't really something to worry about as most of the shots are really quick.. if you were recording event's then it could be a problem.

It all depends on the camera I guess, from what I understand the primeM cameras (like the k30) have manual controls and should allow shutter control but I'm not sure.

The Panasonic cameras with manual control like the gh2 or even my gf1 with a hacked firmware allow control of the shutter as do many other electronic video devices.

The only reason not to give you this control imho is the manufactures intentionally crippling the device or being very lazy, the 5dmark II got manual controls with a firmware update as did so many other devices yet pentax haven't bothered giving the k5 user's any love in this regard.

The mechanical shutter isn't used in the video process on the k5 and most digital camera's.. infact I would be supprised if they are at all?
Old film camera's still used a mechanical shutter, or a rotary disk shutter (or mirror to project an image onto a focus screen.

While the electronic shutter is a sensor process it still has the same effect as if it was a mechanical shutter, it controls how long each frame is exposed to light.

If you were using a camera that had full manual control (like a panasonic gh2) you can set your shutter in video mode just as you do in photography.

If you use a shutter of 1/50, each pixel in the frame revives light at 1/50 of a sec just as it would if you were taking a photo and affects your exposure of the shot.

If you then changed your shutter to 1/100, you would change your exposure by -1ev just as in photo mode and 1/25 would give you +1 ev.

The shutter speed has no effect on the amount of frames you record, on the k5 you will get 25 frames at 1080p.

If your shutter is 1/50, you will get 25 frames at 1/50 of a sec shutter speeds, if you shutter was at 1/2000 you would still only get 25 frames but at much shorter duration of 1/2000 and this freezing action more (removing motion blur and making the video looking a little jerky).


On a side note.. there are still cameras out there that had fast global electronic shutters that allowed you to shoot with flash outdoors even at 1/2000 of a sec! I would love for global electronic shutters to have a come back as the mechanical shutters restrict flash usage outdoors.

I hope this helps.

Just as in taking a photo, video also has a shutter speed which is not to be confused with frame rate.

The Shutter speed determins in video just as in photography how long each pixel is exposed to light, the slower the shutter the more light and motion is captured per frame and the faster the shutter the less light and the less motion that is captured.

In video the k5 uses an electronic rolling shutter, reading line by line of the cmos sensor till it finish's a frame, this is also why we have the jello effect when panning fast as each line records the objects in different positions.

The k5 records 1080p video at 25fps, so in effects we would want a shutter speed of 1/50 to get a nicer look to the video and capture some motion (to help blend movement between frames) if you were in the USA where they use a 60hrz system you might want to use 1/60 to avoid flickering from lights/tv's.

If you were to shoot outoors at say f2 without any nd filters.. your shutter speed would be away up in the thousands freezing movement and not giving any motion blur to blend frames leading to choppy looking video.

The shutter duration isn't available as an option on the k5, the only option being aperture which makes it a total pain to work with at times, especially when I'm also using camera's that have full manual control where I can set everything to suit.

Ouch.. I didn't expect that the gf1, gh2's I use let me switch if I want too. If im right the bitrate is pretty low on the k-01, we hacked the gh2's get much more room and it made a difference to fine details.

Its probably fine though tbh as most ways of playing it back will compress the end product somewhat especially if its put onto youtube and the first film I did for my friends was shot on a canon xl2 (standard deff) and still looked nice on a big screen.

Thanks for that info though.
