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 PXW-Z150 has 120fps with Stacked Sensor!

PXWZ150

Announced just last week the Sony PXW-Z150 gets a lot of right for the low end pro video market.   It has 4k 4:2:0 as many in the competitive price range of $3,595 MSRP. It has 4:2:2 1080p 10 bit at 50mbit  which is a good surprise and it seems to be carried to the also included 120fps full HD 1080p slow motion mode.

The sensor is of the stacked kind and it is 1″ sized, the same as the ones in the RX100 IV and RX10 II from Sony which are really good at slow motion for a low price. However those full specs are not carried through in the high frame rate mode or HFR.  It maxes out at 120fps 1080p instead of 240fps on the RX series in the 1k range and the FS5 which is a tad more expensive than the Z150. → Continue Reading Full Post ←

JVC GY-LS300 Offers Rebate and 120fps Upgrade!

gy-ls300-JVC

What came as sort of a surprise and some mitigated anger to current  recent owners of the camera, JVC announced that the JVC GY-LS300 4k, HD and SD capable camcorder will now be offered at $1,000 USD cheaper from a MSRP of $3,995 to $2,995. Furthermore it has a few new features added in a free firmware upgrade to current and new owners of the camera in April.

The update brings full HD 120fps capability to an already robust camera along with “JVC Log Gamma” recording mode.  The camera offers a Micro 4/3 mount for easy use of different lens mounts including Canon and Nikkor lenses which is a big strength of this setup.  Hundreds of adapted lenses can be used from almost any manufacturer.  The JVC Log mode is supposed to increase dynamic range by 800%. We find that claim a  little on the superlative side and probably will bring 2-3 real stops improvement in DR. → 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 ←
