In reply to:

brumd: I am particularly happy about the silent electronic shutter. That was a feature that I really missed on the original EM5, after I sold my Fujifilm X100. All those opportunities where the sound of a click spoiled the moment.

But.. could someone explain to me what is the actual advantage of a mechanical shutter? Why is it there when apparently it can be done (even faster) without mechanical parts?

Also full electronic shutters tend to have an issues with exposure in very short exposure times, while mechanical shutters are far more consistent and ensure even exposition.

Boris F: No other company came with such amount of innovation with one single camera.
Cheers Oly!

Care to list this whole "amount of innovation" in this body?

ZeneticX: To sony fans: You better hope Olympus would be able to pull it off with sales of their new model. Sony owns a majority stake in Olympus so any gain is beneficial to Sony as a whole.

To olympus fans: Be thankful to Sony. Without them Olympus wouldn't even exist now after the 2011 incident

Copycat Olympus should tanks Hasselblad for ideas.

Cause this whole 40Mpx mode is clearly copied idea from Hassel, even if it differs in details.

Randy Veeman: Think about this.
With an average to good lens how much of a difference would you see between the 2 cameras announced today?
One in a special mode has images 7296 pixels wide.
The other in all modes has images 6480 pixels wide.
There is a difference, but with most lenses I bet it won't be much if anything (noticeable).

Number of pixels ≠ image quality

jdu_sg: So, basically, any kit lens has sufficient resolution to produce a 40mp image, within the feature's performance envelope. That's impressive.

That would explain why from these "40 Mpx files" you don't get a resolution anywhere near the 40 Mpx camera.

Everlast66: This looks like a nice little camera, but I can't believe they are asking $1,100 for a m4/3 body only!

Every A7 feels cheap, no offence meant to it's owners - you get what you paid for. People even swap bayonets on them because of things like that: https://www.youtube.com/watch?v=Hw1NKIGZ4ps

"A sensor is just one component of a camera." - arguably the most important one though.

brownie314: Nice looking camera. Any word on if it focusses any better than previous models? Especially in low light.

(IMHO Panasonic is as good as any DSLR) - I'm laughing hard. Makes me wonder if people posting comments like that ever touched anything else than D3000.

kodos - some people have low needs. I know guys who sold their DSLR gear for Fuji X100 or Sony RX100 (I also know a guy who barely sold his gear for RX1, but changed his mind after borrowing it for a few days). Some people simply never were meant to use DSLR. It doesn't make your camera any better or worse, it just means it's good enough for you.

PicOne: "Hi Res mode is limited to a maximum of ISO 1600 and a minimum aperture of F8 because beyond these points, the image becoming too blurred for the extra resolution to be particularly beneficial."

Huh? Is this a reference to diffraction and noise effects? If there's a reason for shooting in regular 16mp mode at over 1600 ISO or eg. f11, then not seeing why this reason goes away in hi res mode? For noise.. how would a 40mp downsampled shot (back to 16mp) compare?

With 40MPx m4/3 sensor diffraction kicks in already at f/3.5 at f/6.9 Airy disk covers 2x2 pixels. But that's for middle of the visible spectrum. For reds diffraction kicks in at f/2.8 while for the blue light it's f/4.1 - so I presume it's capped at f/8 for a point where additional resolution gives you no benefit what so ever, regardless of wavelength registered by camera.

badi: 7 years to go....

Joke aside... it's a bit sad when you realize the pace these science projects advance... i mean, ok, it is a big project...but 7 years to build... is only one guy building and caring the bricks on the mountain or what...

But... that's what they are doing. You really think that they wait with starting the construction works until glass elements are done? lol

In reply to:

Sirandar: I am interested in what this camera may see and whether more MP will actually result in seeing more or whether other limits such as light gathering, stability and noise will come into play.

I wonder if eventually NASA will park a telescope in orbit on the non-sun facing side of the moon.... there is probably no accessible place darker ..... but is may be more gravitationally wobbly.

PS ..... that may be the biggest ND filter ever made.

ESA got an idea of doing just that - building a telescope on the other side of the moon - sadly just like NASA - they don't have a budget for things like that.

flektogon: So, the CCD technology is not dead yet. I would even say that it must be better than CMOS, if in such an expensive project it is preferred. Just wondering when we are going to see CCD in the digital photography again.

CCDs were always very popular in astrophotography, even among amateurs, not just scientists. When cooled they are much better for working with low levels of light than CMOS sensors (linear response to light, lower noise, better sensitivity at wide range of wavelenghts).

On Canon 7D mirror box filmed at 10,000fps article (175 comments in total)
In reply to:

ProfHankD: Nice video! I think most DSLR users are not aware of the moving slit, which is a cloth curtain that moves left-right in many old SLRs (and why we still call them curtains). The temporal artifacting, nearly identical to electronic rolling shutter, is also something I think many people don't know about. It's also worth mentioning that there is a very different artifacting for leaf shutters used in compact cameras: the iris goes from open to closed and then open again, effectively varying the aperture diameter through the exposure interval (which actually can improve bokeh, but causes strange temporal artifacts within the bokeh for fast-moving objects).

BTW, a high-speed video looking at the other end of the camera is interesting too: the lens in a DSLR typically has to stop down to the desired aperture as the mirror is being lifted. In fact, in some cameras that's what's still in progress in the short interval between the mirror being up and the shutter curtain starting the exposure.

When filming video camera is not using a mechanical shutter, so there is no moving slit as visible on this video.

In reply to:

Glen K Wells: Jusy my two pennyworth but i think it is a mistake by Panasonic to not provide a built in flash.
Ok add-ons are more powerful etc but who are these cameras aimed at?

The LX100 - no flash and now the GM5?
Basic photo punters do not want to carry a separate flash around with them to a friends house or out in their other pocket. Just want to take a quick snap oh hang on everyone I need to find and then attach the flash - hey where did everyone go?
A built in flash is one of the functions that make cameras like the E-M10 and the NEX I mean A6000 lines popular.
A built in flash is dam useful. If there is no room on top anymore why not squeeze one on the front like the days of old - software or the camera can remove red-eye.

Personally I would not choose a camera without one, I know that counts for zip but it is a feature that I look for. Currently have D610, X-E2, NEX-6 and E-M10.

Gonna start a bring back the built in flash campaign haha.

You can use one of small flashes designed for E-mount cameras with RX100. I picked RX100 mkII cause it comes with build in flash with an ability to bounce it from the celling - no, it doesn't have EVF, but IMHO such a tiny EVF on tiny camera is nothing more than a waste of space.

And a lack of interchangable lenses in case of this small camera is actually an advantage - it allows you to get brighter zoom lens than any ILC camera of similar size can offer, and you don't have all the hassle with interchangable lenses.

In reply to:

thxbb12: That's a shame DPR didn't show a comparison of the EVF size compared to other models (Sony RX100 III, Panasonic LX100 and some other MFT bodies).
It's difficult to gauge how small it is compared to a "regular" MFT body (E-M10, GX7, etc.).

I guess they don't want to include it because for most of the people it'd be misleading. Size isn't the only important thing about viewfinder. Here is a specific case, cause it's very small, but otherwise it could lead people into believing that larger EVF is universally better, which is not true.

Herman Dijkhuis: If you wanna go professional go Sony. Canon is too expensive imo.
The war for professional cameras has begone, it will be hard for Canon to stay ahead of Sony.
Acc. to me Sony will win.

They are talking here about use for video. Mirror got nothing to deal with focusing while recording the video. And besides - focusing with split prism OVF is perfectly doable, hardly "much harder", I would even argue it's easier, you never used split sceen with that size of OVF or what?

Group of people choosing between 1DC and LX100 is non extstent. They are totally different cameras. You have no clue what you are talking about.
