On article Sony a7S III initial review (2305 comments in total)

The camera missing from the comparisons is the Blackmagic Design Pocket Cinema Camera 6k. It also has an SLR format, records RAW video in the camera, shoots DCI, can record directly to an external USB 3 connected SSD drive, has peaking and false colors, etc. The only places it misses are no IBIS and weak autofocus (which many videographers don't use).

On article Hands on with the Sony a6600 and a6100 (394 comments in total)

This would have been interesting if I didn't have a Blackmagic PCC 4k sitting in front of me recording BlackMagic Cinema RAW to a 1TB SSD drive. Camera: $1300, SSD drive $170, lens adapter $150 (there is a Sigma 18-35/1.8 which is equivalent to a FF 26-40/2.8) for less than $1800.

Of course, it is not a photo camera, it is a video camera. But a vblog isn't a photo shoot.

What's missing is customer support.

RED should give Hydrogen One buyers a free upgrade to a Hydrogen Two. Other than getting the Hydrogen Two in circulation, it is probably the least expensive way to satisfy the problems of Hydrogen One buyers.

This seems like an amazing piece of glass.

DavidNJ100: People have already commented on the storage. I'm surprised you can't hang an SSD drive off a USB-C 3.1 gen 2 port or store 10-bit video faster than 100Mbps.

But the questions:

1) Which lenses can resolve 265 dpi? A medium format is one thing, but this is still a 35mm frame.

2) Why does it have old communications standards? Bluetooth 4.1? 801.ac? Should have been BT 5.1 and 801.ax (WiFi6). This is supposed to be a leading, high-end camera for multiple years.

801.ax will be mainstream in the lifetime of this camera. BT 4? Really? Bt 5 is 3-years old and my S10 5G has both. I wonder if ToF sensors will start appearing on cameras.

According to DXOMark.com, only a handful of lenses come close to the resolution of the 42Mp A7RII. This is 61Mp.

I shoot video with a Blackmagic Pocket Cinema Camera 4k where 10-bit ProRes 422 HQ is recorded at 220Mp/s and Blackmagic RAW is recorded faster. A high-speed SSD connected with USB-3.1 with a USB-C connector or CFast is needed to keep up. This is their tests, but they also have a test utility. https://www.blackmagicdesign.com/support/faq/59025

On article Choosing a camera Part 3: the trade-offs of sensor size (298 comments in total)
In reply to:

km25: How many cameras of 2019 standards that you know of take bad pictures. Cameras even made five or so years ago are still are valid.
So buy and use what you want. Put your money into glass, "glass is forever, or at least for a long time".
For tomorrow will only come more bells and whistles......which must be had or you cannot take photographers.

But glass has been evolving quickly. The newer lenses are optically much better, often less expensive, have better IS, and often quieter for video.

DavidNJ100: In addition to the 2/3 lb extra weight, 82mm filter vs 77mm.

At $1500, it is less than an IS Canon ($2100) or Nikon ($2800) lens. Doesn't come in native Sony; the Sony GM is double the price. The older Canon is $1800, the F4 Canon $1300, and the Tamron G2 $1200.

Is it really better than the Tamron? Sigma chose not to label it an Art even though I'm sure they wanted to and expected to be able to.

No, they have 3 lines. They have the 50-100, 105, and 135, all Art.

This one didn't measure up.

On article Lexar launches trio of ultra-compact SSD drives (95 comments in total)

Seems to be part of a new range of higher speeds mobile SSDs. SanDisk has a new Extreme Pro which isn't out yet. Both heavier and slightly larger than the previous generation.

These work directly as storage for the new Blackmagic Designs video cameras. Thos cameras do ProRes HQ (10-bit 4:2:2 at 220Mb/s) and also the new Blackmagic RAW at higher speeds. The higher speeds will enable RAW at higher frame rates.

On article Best cameras under $1000 (316 comments in total)

I confused. A camera with a 79% rating beat cameras with 82%, 84%, and 85%.

Do the ratings mean anything? How can this severe deviation exist?

Link | Posted on Mar 14, 2019 at 21:22 UTC as 42nd comment

It will obviously need an adapter for the EF mount because of the distance. The EF lenses will probably have full functionality.

A question may be: will it have a crop sensor mode like the Nikon and Sony?

In reply to:

DavidNJ100: It all depends on lens quality. We passed on the ZS100 because of image quality, IMHO worse than the Sonys, some Canons, and even some Panasonics.

If they have fixed that it will be very attractive.

The G9X and G9XII are also smaller and more pocketable than the other 1" cameras. It really is mostly about the lens (after sensor size), and because of its more modest spec the G9X may have lucked out on image IQ.

We have a Canon G9X, which is the only 1" that is really pocketable in the traditional sense. The lens is fine. Holds up well next to my Sigma 18-35/1.8.

We looked at the ZS100 for the zoom range and 4k video, but the lens was awful. If that is fixed, this could be a good camera.

That said, it is a pretty big and heavy camera not to have a tilt screen.

We need an image comparison with the ZS100 and RX100V/IV. May also the Canon.

The ZS100 had an unacceptably soft lens..we based on it and I'm sure many others did also. If this camera avoids that it could be a great choice. Many times that telephone is very handy to have.

In reply to:

DavidNJ100: You get 4:2:2 at very high bandwidth with an external recorder. Underlying it all is the full-frame sensor, whether A9, A7rIII, or A7SII, is 4x the size of the 4/3rds sensor.

To suggest a case where F9 is needed in a relatively dark room is not a norm but the Sony's would acquit themselves well. What about the more common situation where an F2.8 wide angle is needed? Often the 4/3rds lens doesn't exist.

Sort of defeating the 4/3rds size advantage.

That is starting with an APS-C lens. The Tokina may be the best of that group but not of the caliber of a full-frame lens. The best would be the Sigma 18-35 and 50-100, both f1.8. I have the 18-35 and a 50-150/2.8 which can shoot a 200/4 equivalent.

The Metabones isn't a panacea. According to their site, the GH5 needs full frame lenses and their XL adapter. It hasn't been updated for the new model.

DavidNJ100: The questions are really just 2:

1) Can Canon deliver a camera at the front of the class, it hasn't for a while. I'm tired of reading A7rIII vs D850 comparisons for the top camera.

2) Will they realize Sony is the real competitor and deliver PDAF on the sensor that is competitive with other tracking features? Not to mention video quality, resolution, speeds, rolling shutter, etc.

True, but the point is in a 7D, D500, A6500 we are expecting similar capabilities with a smaller sensor. In many ways, the 7D was better than the 5DM2, and the A6500 was a bust because it didn't deliver the sensor video quality that was expected.

Both the D850 and A7rIII have crop sensor modes and aren't that much more expensive. Other than sensor size and resolution, there are very few if any A7riii features that would not be expected on a 7DM3.
