  1. The AA filter won't make a difference to video. It barely makes a difference at 36MP never mind the 2MP of 1080p. Biggest marketing gimmick ever devised.   The difference in video between the A7 and A7R could still be significant because they use completely different sensors.   So look to the sensor as the differentiating factor.   The AA filter comes under the headline spec along with the sensor, they have bundled the meaningless AA filter spec in with the CMOS which is crazy. On my list of priorities the AA filter comes a distinct LAST! Look at the difference between the RX1 and RXR and you will see what I mean!
  2.   As far as I'm aware the Toshiba sensor in the D5200 and the Canon CMOS in the 5D Mark III don't read out all the data, they do pixel binning. Better than line skipping and they do it well, but no match for the full pixel readout.
  3.   I believe the LCDVF for Blackmagic Pocket camera will attach via magnet. Easy to take on / off.   At the moment I am using their LCDVFe as a small lightweight monitor for Pocket and 5D Mark III shooting.   Here's my Pocket Cinema Camera rig. The audio side is handled by the Roland R26. Very good built in mic on it, but rigging it can be tricky and there's no line-out port, you have to use the headphone jack to connect it to the camera or sync the dual-system audio in post. If you set the headphone jack output on the Roland too loud you will get distortion on the Pocket ProRes audio track.   Top handle and nato rail from Wooden Camera. Excellent build quality and design from them.   The whole rig is very light. I've tried to keep it as un-spidery as possible. Without the Roland it is amazingly discrete and looks pro, not DIY.             That above is my Magic Lantern raw rig. Still the ultimate image quality in my view.   I'm powering both the EVF and camera off a single Switronix PB70 battery with that rig. No more swapping multiple batteries or worrying every 10 minutes about having enough juice!
  4. Sony recently took a stake in Olympus. It's a shame they've not used 5-axis sensor shift on the new cameras. Maybe the next versions.   5 axis works with any sensor size. I've tried it on a recent Olympus compact. Compact is shit but the stabilisation works great! :)
  5. Nice find Julian. The RX10 looks very nice.   The A7R had a bit of false colour but nothing too bad. A massive improvement on previous Sony cameras.   Lots of compression on YouTube so looks softer I am sure, than the original clip. Anyone found original files to download?
  6. I'm expecting the picture profile to take a leap with this too, as they'll have more data to work from.
  7. According to Imaging Resource the new video mode of the new Sony RX10 with 1" sensor is a huge step forwards. The RX10's sensor reads out the entire 5472 x 3080 frame at 60fps sending huge amounts of raw video data to the image processor. The new Bionz X processor is designed to take the 5K video stream (for the first time). The advantage is that Bionz X can intelligently downsample and compress to 1080p from a much higher baseline than usual.

  8. If they are doing on the new full frame sensors the same as on the RX10's new 1" sensor then video is going to be amazing.   The RX10 does a FULL READOUT producing 20MP 6K raw stream at 60fps.   The new Bionz X as featured in the A7 and A7R is powerful enough to then subsample that 6K down to 1080p before writing it to the card.   That means no moire or aliasing, no line skipping on the sensor, no great loss of dynamic range from a poorly subsampled sensor output.   If your credit card is not ruined by now it may well be when the RX10 sample videos start trickling out.
  9. The full frame Sony A7 and A7R are disappointing for lacking 4K and a high bitrate codec (the time is now...), choosing to stay with 1080p and AVCHD from the last generation. However Sony have pushed on in other areas and are promising "pro-quality" video. Marketing speak or genuine breakthrough? Let's take a closer look...

  10.   Glad to hear that, because the Optimo is $50k!   Got any samples from your test? Bring it on :)
  11.   It works on a passive mount yeah. I used the Nikon Speed Booster here, a passive adapter on an active MFT mount = passive :)
  12. If you are doing ETTR at the native ISO 800 then switching to ISO 200 will give you the low noise, as it uses similar pull you will do in post on the ISO 800 footage, but in-camera.   ISO 200 on the Pocket looks great and don't notice the dynamic range being hurt, or worse highlights.
  13.   Great video from Tom there. I met him in Manchester last time he was over, really nice guy and knowledgable.   I am tempted to try this myself but how could we get around monitoring such an over exposed image as alluded to in the top post? The camera needs a ETTR mode!   By the way this only works with raw or 10bit ProRes, not worth trying with a compressed 8bit codec as it will create too much banding.
  14.   I tried it and the image at 18mm is somewhat outside the comfort zone of the APS-C image circle the lens was designed for. Quite murky corners. Either that or something funky is going on with the adapter.   Nice and wide though!
  15.   Amazing 90's fashion sense as well. Superdry should do a Ghost In The Shell themed collection of high collared bright orange jackets. Oh they already do!   Japan is such an amazing place, why are they so uncreative when it comes to cameras?
  16. AVCHD was well implemented on the FS100 compared to a DSLR (even is OK on the GH3), as the H.264 encoder was good, but the wrapper itself is just so unnecessary.   It gives you zero benefit in image quality. What DOES it offer? Oh yeah - a stupid folder structure and inability to play nicely with some editing software or preview clips easily.   Just...get...rid.   What is wrong with Quicktime MOV?
  17.   The wobble is from Warp Stabiliser. Twixtor causes a morphing effect.   The night time tripod mounted shots give you an idea of what the camera looks like with no post trickery.
  18.   Thanks! There's a loupe coming from Kinotehnik for the Pocket. I have their HDMI EVF and loupe. Very well thought out design and good performance. I'm using it on my 5D Mark III rig for raw shooting.   http://www.kinotehnik.com/products/electronic-viewfinder/overview   Hopefully I will be able to get the BMPCC loupe to try out as well!

    The clamps are great, much better quality than any others I've used. I use two, one on my Iscorama and one on my Centa Vision. The guy is a fountain of knowledge. As for the forums you have to get his humour I suppose ;)
  20.   Straight from the card into Premiere and Film Convert. No need for anything in between, no LUT.
  21.   Not unless you really really need AF on a Canon body. Nikon one adapts to a Canon DSLR just fine. The EF-MFT Speed Booster has no ETA. It is lost in space!
  22. I don't use the multiplier on the F-stop when it comes to speaking about low light ability. F1.8 is F1.8! And it is easier just to take it as given that with a smaller sensor you won't get as shallow depth of field as you will on full frame.   Crop factors are only useful in terms of describing the field of view. Everyone in the DSLR video world thinks in terms of full frame. A 28 is a wide, etc.   People in the movie industry don't think like that, they go in terms of Super 35mm and a 18mm is wide on a movie camera.
  23. Yes Warp isn't perfect but the great thing about the Pocket camera is having no rig.   I'll reluctantly dive into adding bits too it later.   It just needs a loupe maybe, and a stock.   Of course you can go crazy and rig it up insanely, the image quality makes it an 'A' camera for a lot of people.   By the way... few more facts about the lens.   - Made in Japan at Sigma's main factory. They are a 100% Japanese family owned company. Not South Korean as with Samyang. - 4 aspherical elements (most lenses have none, some have 1... but FOUR!!?) - Back ordered in the US currently (none at B&H or Adorama). Price will be $799. - I paid 829 euros for my Nikon mount version, the Canon version is usually cheaper in Europe and the UK (on Amazon). - Ultrasonic AF motors - All internally focussing and zooming. Front element never moves an inch.
  24.   Crop factor is just a way of understanding focal lengths, using photographic full frame as the standard.   We think of wide as 28mm, portrait 50mm, and telephoto 135mm+ on full frame.   The crop of the sensor narrows the field of view, so a 28mm x 3 crop = 84mm. It is like taking a photo with a full frame camera and cropping it in Photoshop.   Super 16mm lenses have a smaller image circle but the field of view is the same as a normal lens, so if it is a 50mm on a Super 16mm sensor the 3x crop applies when thinking in terms of full frame field of views. 50mm is telephoto on Super 16mm not portrait.
