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.

We have gotten a few questions about the EOS 5D Mark IV when it comes to it’s 120fps 720p slow motion mode. We covered it back in August but samples were hard to find back then; all that has changed and now we can rate and position the camera in our HSC Camera Guide ranking. While it will not win any contests for resolution or frame rate we think it is a good all around camera with useful features for video enthusiasts.
The negatives like high price, Moire & Aliasing prone slow mo resolution, huge inefficient 4k bit rates on an old codec, 1.74x crop in 4k recording and big system bulk still apply for this camera. The Panasonic GH5 for instance destroys the 5D Mark IV in the video spec department but that is ok considering the 5D Mark IV is a stills workhorse with a full frame sensor first and an excellent AF and high ISO performance package.
For many the EOS 5D Mark IV was to be the resurrection of the DSLR camera as a video professional’s tool of choice. However just looking at the reactions online and the spec sheet itself it looks like Canon missed the mark by a mile in this aspect. Several camera shortcomings like the codec, crop factor in 4k and lower resolution for higher frame rates come to mind.
The over four year wait which was about the same between the Mark II and Mark III models is extremely long for a product class that needs to evolve constantly in order to remain competitive. With Sony and Panasonic doing real innovation in the video space in a much smaller time frame usually 18 months, Canon needed a product that could withstand to scrutiny for a few years.
We have been following the rumors on the next version of the Canon 5D with some subdued but hopeful enthusiasm. However, as many rumor sites now claim the final specs for the camera to be released next month probably at Photokina; it is clear that there is a big disconnect in performance from the common DSLRs in the Canon line and the mirror-less competitors from Sony and Panasonic.
There is a lot to like in the camera specs but also a lot of disappointing things for the video enthusiast or professional. The camera has always been primarily a stills powerhouse and it is clear that this pedigree is maintained in the Mark 4. Auto Focus with dual pixel tracking support, pixel count and sensor should be heavily improved along with dynamic range as seen in the 80D and the impressive 1DX Mark II.
We are just a couple of months away from Photokina 2016 which takes place from Sept 20-25th in Cologne Germany. There are quite a few refresh expectations when it comes to cameras but there are also rumors of new announcements. As to what is solid and or dependable remains a mystery but rest assured there will be some good hardware presented.
For starters the updates to popular higher end camera lines in the Nikon, Canon, Sony and Panasonic lines should be announced with most of them sporting higher frame rates as specs. Continuous Phase Auto focus will continue to be a trend this year as more sensors support it.
Canon is often accused of being too slow to react and update their line compared to the competition. However when you look back and see cameras like the 7D Mark 1 which introduced 60p 720p video to the EOS line it is much harder to judge them as other cameras topped at 30p.
The 5D Mark III has been a best selling camera for Canon but it is getting long in the tooth. The lack of 4k video is a sore spot for the camera line that introduced cinematic looking footage to the masses. The upcoming 5D mark IV (4) rumors suggest that not only 4k is in the cards but 1080p 120fps as well.
