Lawn Mower Cutting Grass at 50,000fps is Amazing!

Destin from SmarterEveryDay has posted an incredible video explaining how a lawn mower cuts grass. It is way more interesting and memorable than you might think. The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even.  The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera.  Highly Recommended to watch and subscribe to SmarterEveryDay for more great content! -HSC

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 a6500 Slow Motion and Overheating!

Sony a6500 Slow Motion

The Sony a6500 came as a big surprise to a6300 owners in that their camera was loosing value overnight in the secondary market to a near identical close with a touch screen and IBIS stabilization.  However the camera has still not reached the hands of many pre order customers but we were able to find a few insights on the 120fps full HD slow motion mode.

The quality should be very similar to the a6300 since the sensor is identical but with slight improvements in the dynamic range and color pipeline should yield a slight increase in per pixel definition. The compression should be very close with the XAVC-S codec at 21Mbps at 24p and or 50Mbps at 60p with easily selectable formats. → Continue Reading Full Post ←

Sony a6500 Keeps 120fps On Refined Update!

Sony a6500 front with lens.

On a clearly unexpected update of the a6xxx line of cameras Sony unveiled the α6500 E Mount camera much to the anger of people who just 6 months ago were buying the a6300 which became a darling for video shooters and APS-C photo shooters aswell. That camera brought oversampling of 6k to derive a 4k output which up to now created the sharpest and most detailed 4k image in consumer cameras.

However things were not all rosy with the a6300, many users cringed at the excessive rolling shutter skew when shooting 4k and the lack of dependable continuous tracking. There was also a lack of touch screen and no sensor stabilization which the a6500 aims to correct.  There is a lot of camera here so lets dig in… → Continue Reading Full Post ←

Nikon KeyMission 170 4K Does 240fps!

nikon keymission 170 4k Action Camera

One of the Photokina announcements that peaked our interest was the Nikon KeyMission 170 Action Camera which aims to disrupt the already crowded space of all weather sports segment.  We have a plethora of options from the leader GoPro and close competitors like Sony, Xiaomi, Olympus, Garmin and even Panasonic.  So another entry by Nikon seems to go by unnoticed however this hardware looks to be very capable and can go head to head with the best.

The slow motion capabilities are the standard for high end action cameras here with 120fps at 1080p and 240fps at 720p.  While these are becoming standard frame rates for the most part; there is a clear distinction on quality between cameras with Sony Action Cam being clearly superior in compression with XAVC S to GoPro for example.  ProTune on the Hero 4 and 5 does make a difference but Sony has the edge with an overall better codec that is low artifact. → Continue Reading Full Post ←
