Calvin Chann: Imagine losing 1TB of data

Finding 1 TB of selfies, the joy!

Completely OT: every time I read the camera's name my brain changes "50S" into "505" and my internal radio plays that brilliant song by Arctic Monkeys. Best camera feature ever! :)

On article 6K here we come: Here's the new Panasonic Lumix DMC-GH5 (170 comments in total)
In reply to:

MrCentrist: While no one has a 6K TV, 6K is a very valuable feature. It allows zooming and panning to be added during editing (Google "ken burns effect"), as well as improved stabilization during editing too. And while almost no 4K video from ILCs is close to the 2160 lines of resolution (most do not come close), 6K video can be "downsize" so there really are 2160 line of resolution and one can get the full benefit of their 4K TV. Basically 6K video on a 4K TV will blow away almost all 4K video from inferior 4K ILCs when it comes to detail.

@Steve: there's a big difference between the pro segment and the mass market. I've never seen a 4k capable camera being marketed as "the ideal tool to produce stunning 1080p video". After all, this would imply that a 4k filming device is somewhat lacking for a high-quality 4k production... (which actually is the case, as the OP noted)

Very interesting perspective! It would actually make lots of sense to produce video capturing devices that record at a higher resolution than the concurrent displaying standard. However, I fear that marketing departments wouldn't know how to sell this.

Greg VdB: "The GH5 will also offer a 6K Photo mode that will allow you to extract 18MP stills from burst footage"

So it's just a reduced-size/increased-burst-speed mode instead of 6k video? Rather leading title then...

So it's very-short-duration video that they choose to call "6K Photo"? This convergence of video and stills is getting very confusing :-)

Now I get it! Barney's disappointment must be similar to what we've all felt whenever it took two years before our camera of interest was reviewed ;-)

Barney, stop over-thinking it, and just go out and play with the damn thing ;-) (I know, it's your job...)

By the way, dual pixel was "first introduced" in the 70D...

In reply to:

J A C S: I wish that the screen had been designed so that it could tilt facing up, not just down. Well, I guess I can always turn the camera upside down...

Still not sure what J A C S meant. If it really is about tilting the screen to face the front of the camera - to take selfies/group shots - then I definitely agree when it comes to shooting from a tripod, which the current design doesn't allow.

In reply to:

Donnie G: As the first mirrorless Canon designed to appeal to North American and European tastes, it will be interesting to see how well the M5 does in those specific markets over the next six months. If this very well designed compact ILC can't deliver the sales numbers that Canon expects, then I don"t think any mirrorless compact made by anybody will do the job either. So, is mirrorless strictly an Asian revolution or is it global? Looks like we will know soon enough. :))

I might have agreed if the 80D wasn't recently launched - now for sure, some people who might have been interested in the M5 already upgraded to that camera.

Of course there's room for improvement - just as is the case for each of its competitors - but Canon surely joins the fray of enthusiast MILC's in a convincing way. Competition is good, and it's exciting to see mirrorless coming of age. For Canon, the next step has to be a FF mirrorless to rival the a7 line. With dual pixel, a good UI, a more dslr-like form factor (larger battery!), and their huge client base, they could cause quite the stir in this segment. In my wildest dreams, the 6D will be replaced by a 6D II dslr and a 6D-M mirrorless equivalent, Sony responds with a dslr-shaped FF mirrorless with improved ergonomics, and some of the others also enter the FF mirrorless market. A man can dream... (untill the next troll wakes him up)

On article Samyang goes Premium with MF lens range (58 comments in total)
In reply to:

Steenoe: The Laowa 12mm seems like a really interesting alternative to this. It accepts 100mm filters and has a hard stop at infinity!
http://www.venuslens.net/product/laowa-12mm-f2-8-zero-d/
My 14mm UMC Samyang, can focus 2 lightyears past infinity, and I dont really need that ;-) and the distance scale is way off at long distances. Hope Samyang took a look at those issues with this new lens.

A hard stop at infinity is only good if you're not too picky about critical focus. If you're into astrophotography for instance and you need the stars to be sharp, even the tiniest nudge will throw off focus and be apparent in your images. Moreover, "critical infinity focus" can be slightly different on different camera bodies for the same lens. Also, there's many instances of lenses with a hard stop where critical focus lies just beyond the hard stop because of miss-calibration in the factory. (I personally had to open my Tokina 11-16mm to fix the latter problem)

In reply to:

matthew saville: The MTF of that 14mm is unreal. Considering the weight, if it's $999 or less I'll be all over it. The Irix 15mm may have just been sidelined for astro-landscape work!

From sample images I've seen on Irix's Flickr stream and the Lenstip gallery, the Irix 15mm has terrible vignetting as well, so the Samyang definitely looks more promising for astro. Let's hope though that QC of the premium line is better than that of regular Samyang lenses...

it's a natural process. Those punks are just species of local fauna exploring their habitat. Not malicious, just feral.

I believe their species is called Homo idiocracy...

But can someone help me remember the name of this digital camera in the 1990's that was saving VGA pictures on a 3 1/2 Floppy disk, before memory cards appear...
I used one at work, for technical photo,

To answer the question of where to go next: I stepped into digital photography with a Casio QV4000, and while this in itself is probably too "small" in a historical sense, it sported the same lens as the far more illustrious Canon PowerShot G2. Given that the G-line still exists today, it would make for a great subject.
