I'm shocked the Fuji Medium Format camera was voted most exciting announcement. I was sure it was going to be the Nikon action camera!

Louis_Dobson: It's very nice, but I'm not sure I understand the point. The resolution is no higher than the hi-res FF cameras, which also have more latitude then you will ever need at low ISO, and I can't see this camera as a high ISO sports camera.

So what can it do that a hi res FF can't?

The sensor is slightly bigger, so that offers slightly higher resolution potential, slightly higher microcontrast etc.

It's not a big improvement considering the price - they need to up the resolution to compete with the next generation of >50MP FF cameras.

Doesn't look like there's any chance of squeezing a 645 sensor behind that mount, looks like this has been designed from the ground up as a 44x33 system.

That should give it some advantages over Pentax's 645D/Z in terms of lenses, but if Pentax come out with a full frame digital MF...

In reply to:

Marco Nero: Sigma seem to enjoy replicating all the other lenses already out there so I suspect that they simply reverse-engineer existing lenses and then rebuild and refine them. There's times when I've had to take off an f/1.4 lens and replace it with an f/1.2 lens simply because the ambient light or the room itself was too dark... so f/1.2 is still desirable. The Canon 85mm f/1.2L is still going to have that edge although I'm sure the Sigma Art users will still be happy just as long as the long and unresolved Sigma QC issues aren't present. Looking forward to seeing samples from Sigma nonetheless. No doubt the faster claimed AF will make many happy. Haven't seen what the lens hood for this lens looks like either. I might have been tempted by Sigma if their 85mm f/1.4 Art was out sooner... but some of my absolute favorite shots have come from the Canon 85mm f/1.2L. Sigma sure took their time with this one. I think the Sony shooters are annoyed too.

Firstly your initial claim that Sigma are reverse engineering other's lens designs is the most ridiculous thing I've read for a while (and I've read a lot of Photokina threads recently), their designs are considerably more complex and share no resemblance to traditional lens designs.

Secondly, I hate to break it to you but moving from f/1.4 to f/1.2 will gain you almost nothing in sensitivity when shooting in low light - due to vignetting at the microlens level. When using an f/1.2 lens all that happens is your camera silently increases the ISO setting.

If you don't believe me, check this out:

https://www.dxomark.com/Reviews/F-stop-blues

or even better try it yourself - shoot an image with an f/1.2 lens wide open, then press the lens release button and give the lens a small twist to disconnect the electronics and shoot another image. I did this with my 85mm f/1.2 and the second image (when the camera couldn't recognise the attached lens) was indeed darker.

On article 6K here we come: Here's the new Panasonic Lumix DMC-GH5 (172 comments in total)
In reply to:

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...

estarkey:

It's not a stupid question at all - it makes a huge difference whether the camera can do bursts of 24fps, and whether it can do this for longer than a second. If not then the feature is extremely limited.

Notice how the announcement form Panasonic very carefully avoided stating the camera shot 6K video, only talking about 6K "photo" and not providing any information on burst rate or duration.

I highly doubt it will be anything like 5 minutes, 30 seconds is very unlikely, but you are entitled to believe what you want...

yonsarh: My computer is even slow editing in 4K..
I wonder if my PC could handle 6K video editing..
Is it just me, I think 1080p is enough for video ?

A 1080p camera has an effective resolution in the red and blue channels of only 960 x 540. That's not enough for high quality 1080p video output, nor is it enough for chroma keying etc.

In reply to:

mgrum: "6K here we come" - given that's for still only (6K video would be a huge deal) why not refer to the megapixel count instead, as that's what most people understand?

The headline should have been "24MP here we come",

or rather:

"Micro 43rds finally catches up with 2009 stills resolution".

kikiriki:

30p for how long? Half a second? A second? That's not really video in the way most people use the term. How many consider the Nikon V1 to be a 4K 60p RAW video camera?

maljo@inreach.com: 6K? I guess you can never have too much quality. I haven't filled out my 4K video collection yet.

If you read past the sensationalist headline it's 6K stills, i.e. the camera has a 24 megapixel sensor.

It's 6K stills only (or to refer to it in a sensible way, 24 megapixel stills), there is no 6K video.

spidercrown: sensor's dynamic range may no longer matter in the near future.

The dynamic range of this camera sensor is low, it's just taking multiple exposures to produce HDR images, just like photographers have been doing for years.

In reply to:

dtibi: I'm thinking if the sony A7R2 would handle this scenario or not. But probably not.

Not in video mode, but for stills, sure. As far as I can tell this camera is just doing multiple exposures per frame in order to extend the dynamic range, like photographers haver been doing for years. There's nothing revolutionary going on.

CaMeRa QuEsT: Is the rocket nozzle moving up and down a lot or is it just a terrible case of rolling shutter due to vibration of the camera itself?

I believe it's thrust vectoring of the nozzle, not a camera artifact.

PanoMax: Would be nice if they used a Foveon sensor

@HowAboutRAW

The only way the Quattro competes with medium format is in awkwardness!

The images look good because of the amount of deconvolution sharpening and processing applied by SPP. You can do the same thing to Bayer images with good results...

Nikonandmore: I have the feeling, just about all lenses now are "Leica" and MF price range. Sony, Zeiss, Canon, Nikon.. amazing! I don't understand how these manufactures survive to sell enough of these or how people manage to have money to feed this price frenzy. It will only take cell phone sensors, lenses and technology to get a bit better FOR ONE to buy DSLRs anymore. This market is dead and at these prices, sinking faster and faster. Costs 10 grand (or more) these days to buy a pro/enthusiast grade body and 2 or 3 lenses. Sorry, but this and it's pricing momentum is all becoming absurd. And mind you, these new lenses are all mass produced in 3rd world countries and with more and more dubious quality control. Long gone are the "Made in Japan" days with solid products made with extremely qualified manual labor, excellent quality control AND real long-term post sales support! Indeed Leicas start looking really affordable..

Cell phone sensors will never match DSLRs, there's really not much more room to improve - once you convert 100% of the incoming photons the only thing you can do is capture more photons, which means things have to get bigger.

Lens pricing has gone up, but so too has the quality. In fact the current lenses are arguably better value for money. Look at how much Canon used to ask for their original 35mm f/1.4L. If you don't want to pay these prices, the old lenses are still available for decent prices.

And finally there's no evidence quality control was any better in the good ol' days, I'd guess variance was just as high but no-one knew about it because film was too expensive to waste on shooting test charts and brick walls!

Zeiss Batis 85mm f/1.8 anyone?

TyphoonTW: 70-300mm F4.5 – 5.6 = $1,200
Is Sony slowly trying to compete with Leica?

@TyphoonTW:

"Why are we comparing this to Canon's L lens? Just because it has the letter G ?"

Yes.

shigzeo: In contrast to anachronistic cameras from Fujifilm, Olympus, and even Nikon, this is refreshingly forward-looking. And unlike Sony, it isn't festooned with badges. Is it pretty? I'm not sure, but it is attractive. Well done.

I assumed by "badges" you meant features, because looking at my A7R there are only 2 badges on it which hardly seems excessive... as for the number icons, I turned those off as soon as I got the camera....

In reply to:

Thematic: Fantastic releases.

Depending on where the prices settle, these models with a nice ART series lens should make for a compelling combo.

Macro, comercial, still life, landscape, travel, portrait, documentary, fine art etc.

Exciting!

You mean... macro (in really good light/studio), commercial (in a studio), still life (with a tripod), landscape (in good light), travel (in good light), portrait (in a studio), documentary (in really good light), fine art (in good light).
