Sony a6400 Brings 120fps AF tracking to the Masses!

Sony a6400 slow motion

The newly announced Sony a6400 is what the a6300 should have been almost two years ago. It is still missing a key feature that was introduced with the a6500 that of IBIS or Sensor Stabilization which works with any lens added to the system. However, if you remove the IBIS fail from the equation this is a killer camera for just $900 which in this day and age of $1000+ cellphones, it is quite a bargain for the body only.

We were amazed by the 120fps full HD quality of other sony alpha cameras like the a9 and the a7 III which fully track subjects while recording in super slow motion which really makes the feature stand out compared to other cameras which force you to go manual while on that mode.  The codec quality has also been bumped in this camera for 120p to 100Mbps from 60Mbps on earlier cameras like the a6300 which should preserve more detail while sacrificing little in image crispness. → Continue Reading Full Post ←

Schlieren Imaging Slow Motion DIY!

Schlieren Imaging Slow Motion

Sometimes all it takes to embark on a new project is some unexpected inspiration.  On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment.   The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.

You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”,  you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane. → Continue Reading Full Post ←

Sony a9 Slow Motion Has Impressive Quality!

Sony a9 Slow Motion

The Sony a9 impressed with its full frame 20fps Stills shooting at  24.2 Megapixels.  It is probably the most groundbreaking camera performance wise we have come across for sports shooters in a decade.  The AF performance is second to none and as recent samples show it is just as good in video mode. Sony has cracked the continuous AF for video performance threshold where it can be used for production. That is no small feat.

What was totally unexpected was that the 120fps slow motion mode at full HD, which has a full sensor downsampling without crop of the 35mm FF sensor, is not only good; but probably the most detailed full HD slow motion mode we have seen in a DSLR or Mirrorless camera to date. → Continue Reading Full Post ←

Sony Alpha a9 Mirrorless Has Full HD at 120fps!

Sony Alpha a9 Mirrorless

Sony is taking straight aim at Canon and Nikon’s Professional sports photography market with the new Alpha a9 Mirrorless. It shoots 20fps full frame at 24.2 Megapixels RAW 14 bit up to a maximum  241 raw frames or 12 seconds before writing to the card. This is not only impressive but world class leading. Furthermore the camera is able to do it with full AF using a new 693 point system and without frame blackout in the viewfinder.

The Camera has a now standard slow motion mode in Sony cameras of 120fps at Full HD 1080p resolution with great detail. This is done with the help of a new stacked full frame sensor which is the technology perfected in the Sony RX series and now the Xperia Phones. However the lack of any professional video profiles like S-Log3 will put off the video centric crowd. → Continue Reading Full Post ←

Sony a99 II Slow Motion Samples!

Sony a99 II Slow Motion

The Sony a99 II with SLT “fixed translucent mirror design” has been awaited by the A Mount users who only have this camera to upgrade. It is by no means a slouch with it’s impressive specs like 42MP BSI Sensor and 12fps full AF picture shooting.  It also has 4k video recording at 24, 25 and 30p and a 120fps slow motion mode that works at 1080p full HD.

The slow motion quality has been mostly an obscure feature since no samples have been available until recently.  The original a99 had 60fps full HD on a 24MP sensor but the a99 II Doubles every spec and performance is not affected. It is really a monster of a camera for still shooters that can go head to head with the Nikon D5 and or Canon 1DX Mark II without skipping a beat. → Continue Reading Full Post ←

Sony a6500 New Slow Motion Samples!

Sony a6500 New Slow Motion Samples

We have now a fairly good amount of slow motion samples for the Sony a6500 compact APS-C Camera to share with you.  It is clear that the quality this camera can provide is above the norm but we still do see some aliasing in diagonal fine lines which is to be expected by a sensor that is skipping some of the lines to achieve 1080p 120fps.

While the 4k UHD in this camera is derived from an oversampling of 6k; the 1080p 120fps is being extracted from a 24.2MP sensor using a 13MP effective crop factor 1.9x;  is throwing away some line information to get there. Also the camera caps frame rate output over HDMI at 60fps so there is no way to record super slow motion to an external recorder at 120fps. → Continue Reading Full Post ←
