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 a6300 Rolling Shutter for Slow Motion?

Sonya6300rs

There has been a lot of talk lately about the Sony a6300 horrific rolling shutter performance.  Most early adopters are crying foul at the skew and jello movement artifacts when hand holding, panning or using a long telephoto lens.  There is however a big question that has been answered concerning 1080p;  that is how bad is rolling shutter in the 1080p modes including 120fps? Sort answer is about 1/10th to 1/6th that of the 4k mode.

Mark Puckett of the Photo /Video Show set out to find out about the rolling shutter in the Sony a6300 first hand using panning motion while testing the different modes in the camera including 4k 24p, 30p nad 1080p 120fps and 60fps. → Continue Reading Full Post ←

Sony a6300 delivers 4k Plus 120fps FHD Slowmo!

Sonya6300

The Sony a6000 was a good middle of the line performer with pretty competitive performance. The new a6300 is a refined version with some pretty robust improvements in the video area.

For starters the 4k 30p, 24p, 25p video internal mode records in the robust XAVC-S video format at up to 100Mbps which is comparable to what the Panasonic GH4 and a7s II cameras record 4k into.  It also has S-Log3 Gamma for a flat profile for creative grading and LUT application for editors and colorists.   If you were looking for a Sony 4k alternative in an S35 crop sensor then this is the camera for you.   Furthermore the 4k mode is using the entire S35 frame and correctly down-sampling the image for extremely crisp looking 4k video from a 6k original sensor source. → Continue Reading Full Post ←

Sony A7S II 120fps Slow Motion Quality Tests!

A7SII

The Sony A7S II had a lot to live up to considering low light performance and it has so far been exceptional. But the question about slow motion quality lingered as to a new Spec of 1080p 120fps would perform compared to the previous 720p 120fps and to regular 1080p 60 video.   New video tests have surfaced that show how good and or limited the new slow motion spec is on this camera. Many will be satisfied with just the 4k video at astounding levels of ISO which short of the Canon ME20F-SH with 4 million ISO it is the best second option with more resolution at a Max ISO of 409,600.

The Slow motion spec seems to be somewhat limited in quality compared to normal video on the Sony A7S II with a reported 20Mbit/sec for 120fps which is the 100Mbit/sec camera spec stretched 5x to playback at 24p.  20 Mbit is’t that bad considering it is 1080p and the artifacts are well controlled. There are some here and there including some compression macro-blocks if you search for them but for the vast majority of users the camera has a very good slow motion mode built in; albeit at 120fps as it will go no further up the frame rate scale. → Continue Reading Full Post ←
