evogt500: Those "camera" usb sticks will probably not fit in most laptops. Why make something less useful?

Practicality and value are not the primary motivations for those who chose to spend roughly US$80-$90 on a 8GB/16GB USB drive. These are collector items.

That said, which laptops are you referring to? It looks to me like these should be compatible with just about any laptop that has a USB type A port - they might get in the way of other ports, but they should be usable.

Any chance that a variant of these new sensors could have on-sensor phase-detect AF points? I own a GFX 50S, more confident AF would be great for use with lenses like the 110mm f/2. As it is now, autofocus is extremely accurate in one-shot, and usually reasonably quick - but servo-AF is, well, rather slow and has a tendency to hunt, I'm better off just using one-shot.

Dianoda: No mention of display gamut? Are these wide-gamut/DCI-P3 like the Studio or do they continue with sRGB like the previous-gen Surfacebooks?

The local print shop that I work with utilizes a ZBE Chromira printer and requests files saved as uncompressed 8-bit TIFF's in the Adobe RGB colorspace. I would prefer a wide gamut display option, even if I'd still be relying on an external display (one attached to a different computer, even) to finish prepping images for print, it'd be convenient for editing/soft-proofing images on the go.

Boeing skipper: Images 18 and 21 show a lot of red dots in the recovered shadows.
Is that the compression, dead pixels, problem with the camera?

It's pushing the file too far in post. There is a limit to shadow recovery.

Well, up to 60K. Canon date codes and lens serial numbers are a bit of a mystery/moving target, but typically each lens contains a code that can be use to identify the month/year of manufacture, which revision the lens is, and some way to identify the factory that manufactured the lens. For the 50mm f/1.4, I believe the first two digits refer to month of manufacture (in this case being the first half of 2017 - Jan 2017 = 49, Feb 2017 = 50, etc.), and my guess would be that the next two digits refer to the facility of manufacture (1) and product revision number (8 - this lens has been in production since 1993, not too surprising that there would be this many revisions). The next 4 digits would be a sequential serial number during the month of production for that factory/product revision, we don't actually know how many lenses are affected. But I'm fairly confident there were 6 months of suspect EF 50mm f/1.4 production at one Canon factory.

Ah, you are correct, the full license cost has come down since I first starting working with the software. A license for Studio is now $300 in the US. That said, for my needs, the free version of 12.5 has proved to be more than capable enough; honestly, I feel like I've barely touched the surface of what the software can do.

I'll second davinci resolve as an excellent free video editor - a few of the more advanced features are locked unless you purchase the full license ($1K), but all the basics and then some are available in the free version. It's a decent editor to start learning on.

CaPi: What on earth,.. Won't make any sense in terms of sensor usage but hey..

@shigzeo

I suppose a better word choice to describe the GFX+Cambo+TS-E combo relative to the HCam would have been "compact." There really is not much else out there that provides the functionality and flexibility the HCam offers, but if you just want to shoot TS-E lenses on a larger than 35mm, it's possible some may find the GFX+Cambo adapter solution more appealing.

Either way, I find myself on the outside looking in, as I've yet to touch digital MF. But as a longtime user of Canon 35mm cameras and TS-E lenses, I've always been intrigued by the prospect of using the 17mm/24mm TS-E lenses on a larger sensor.

The 17mm and 24mm TS-E lenses have huge image circles (approx 67mm), they more than cover the GFX sensor, even with significant movements. Mounting these lenses on the GFX with one of these adapters would be quite a bit more elegant than previous solutions like the Hartblei HCam-B1.

This was my first camera, got me started on photography. Image quality was, er, different compared to most other cameras. I had a lot of fun with it.

On article Drone footage captures the raw power of Iceland (56 comments in total)
In reply to:

Reactive: I found Iceland to be a depressingly barren, grey and dull place to visit, and I've spent years out walking in the great outdoors. Sure it's interesting to see how the flora, fauna and humans have had to adapt to their environment, but the endless vistas of barren moonscape and Armageddon lifelessness can make for some very dull days. There's only so much rock you can shoot! This video shows that very well, so in that respect it's a great film.

As an alternative , try Tangerine Dream's 'Canyon Dreams' video; lots of rock but at least there's some colour ;-)

I was in Iceland for about a week and a half in late May, the color can be somewhat dreary during the changing seasons, but once the sun comes out, it was quite lovely. If you have the means, my vote is go. I'm certainly planning to return - I'd love to see the country in winter, and I'd like to hike the Laugavegurinn in summer.

Direct flights from the US to Reykjavik were surprisingly affordable (at least with respect to the other international travel options I researched). My group did about a 50/50 split between camping and hotels/airbnb, several days in Reykjavik and then a loop of Route 1 (aka ring road) - all-in costs (flights/car rental/petrol/accommodations/food) ended up being around US$3K/person for a 10 day/9 night trip.

On article BenQ announces 32" 4K high dynamic range monitor (84 comments in total)

The specs quoted here for the PV270 are inaccurate. It's a 1440P display that covers 96% of DCI-P3 (which is in most respects a wider color space that adobeRGB), has several advanced features absent from the SW2700PT, such as a brightness uniformity compensation mode, quick stability on start-up, etc.

There are several inaccuracies on page 8 in the Leica Q summary - "The Q's 28mm equivalent F1.7 image-stabilized lens is incredibly sharp and its 24MP APS-C-size CMOS sensor produces good image quality" - the lens offers a true 28mm focal length, and the sensor is full-frame. Cheers.

MrTaikitso: If the 'follow me' mode is as good or better than the DJI Phantom 4 does then GoPro have a hit on their hands. One thing, anyone know what the flight time is on one battery charge? Latest DJI is about 25 mins.

Gopro website specs flight time at up to 20 minutes on a one hour charge. Battery is 5100mAh 14.8V. Assuming the software/controls are fully baked, it could be a winner.

85mm f/1.4 and 500mm f/4 cool stuff. No sealing on the 85mm is acceptable, but the lack of weather sealing on the 12-24mm f/4 is a bummer, that really limits the appeal of the lens for landscape use.

Very cool, I love the focus on portability. Bundled pricing with the hero5/black5 seems pretty decent for a ready to fly gopro drone. Looking forward to reviews.

On article Canon EOS M5: What you need to know (564 comments in total)
In reply to:

MasterWayne: The most important question for me: How do adapted EF/EF-S lenses perform?
Comparable to 80D's live view? Are any of the M5's features (peaking, ...) disabled?

To add on to what BEKippe had to say, yes, extreme angles of incidence for light hitting the the edges/corners of a sensor can result in increased vignetting in those sections of the frame.

There are three primary factors at play:

- lens design - flange distance
- lens design - angle of view
- sensor design, in particular, microlens arrangement/optimization, and possibly sensor stack thickness

The steepest angles of incidence will occur with ultra wide angle lenses designed for short flange distances, which could result in dark corners when paired with sensor microlens arrangements that expect less extreme angles of incidence, as the amount of light that actually reaches the photosites is reduced. However, sensor microlens arrangements can be optimized for increased light collection in these cases - and the sensor designs used in most current mirrorless cameras already make use of such optimizations. The Sony A7 line, for example:
