On BPG image format aims to replace JPEGs article (198 comments in total)
In reply to:

The Squire: Would be great to have a file format with a size somewhere between JPEG and RAW, that holds enough data for a bit of post-processing.

I'd love a standardized compressed RAW format. 14bit, bayer data but with varying levels of loss-less to lossy data compression.

DNG is an open standard so there's nothing stopping camera makers from using it, or browsers supporting it for that matter.

In reply to:

samfan: In the past few years, both Google and Microsft introduced their replacement formats and both failed miserably.

It's weird. Is there any other file format as old as JPG still so widely used? Besides plain text I mean.

JPEG became standard in 1992. Same year as Intel Indeo came into existence as a video format. Remember Intel Indeo? We've probably had 20+ major video formats between then and now. That's how old JPEG is in computer terms.

Well, considering that even GIF is still a thing, I hope for an image format that can replace JPEG, GIF and PNG all at once. Heck ideally it could have some compressed RAW capability, maybe that would give it traction at least in cameras.

> Is there any other file format as old as JPG still so widely used? Besides plain text I mean.

MP3 comes to mind, it's the same age as JPEG.

We already have that - DNG has supported lossy compression for a few years now

Boss of Sony: I thought this was the ideal camera until I realized it was the same size as the A6000 with one of its small lenses on it. A6000 has twice the sensor size, twice the megapixels, and the option of changing lenses, plus it's cheaper.

@Boss of Sony the "special" is the size :)

frosti7: Low pixel count? really?

There are disadvantages to having a high pixel count as well, so it's a trade-off.

In reply to:

Morten Rasmussen: Dpreview are Panasonic fanboys. You should consider this when you read their reviews.

What I mean is;

How come a camera that was launched so recently already gets a review and a very good one, when the Sony a5100, which, I may add, probably blows the LX100 out of the water, and is same size or smaller, doesn't get reviewed.

It's always the same when panasonic ships a new camera Dpreview is right there, but not so much with the other brands. One could get the impression that they benefit somehow.

They probably prioritise by the amount of "buzz" created, and it seemed to me the LX100 (something quite different for its class) created more reader buzz than the a5100 (an incremental upgrade)

Paul Kersey Photography: In the lab, this camera looks great. having said that, and I have used many Panasonic m43s over the years, the real world output Raw files have consistently been pedestrian.

If Panasonic would use a Sony sensor like that used in the Nex-6, now then you would have the ideal camera for casual shooting.

When was the last time you used one? I found the sensor they're using in the GX7 etc. quite a big improvement over previous sensors for raw PP.

In reply to:

art99: It offers 4K video but no mic input. So that means there was absolutely no room to squeeze in somewhere a mic jack. How about making the camera just a wee bit larger like the size of a Leica M, this way there would also be room for another unthought of jack...the headphone jack ??
I know many will say that this was not meant as a video cam BUT, in that case why would they make it with 4K ????
Sorry Panny, no jacks no buy. Maybe on the LX200

You'd get much better audio quality by using a small hot-shoe mountable audio recorder (something like a Zoom H1) anyway, the analogue amps of anything less than pro video cameras tend to be a bit crappy.

You can say that about any ILC (Why get the LX100 when you can get the GM5 etc.), but you won't find an ILC lens anything like the LX100's

In reply to:

hyfan: How come they don't use more sensor area in 1:1 mode?

Well 3088px is the maximum height they're using, probably taken some shortcuts with any physical lines above/below that.

TORN: Taking a snapshot wih this camera at Photokina felt like:

- switch on and wait for the camera to boot and then for the complex lens design to unfold and automatically zoom to a focal length which you most probably want to change

- use motorzoom to get the right zoom

- fiddle around with setting the right focus point

- snap

This process can easily take up to 5 seconds. At least this is something a buyer should be aware of. When using a zoom I much prefer a lens I do not have to wait for when switching the camera on and a second time when zooming.

> fiddle around with setting the right focus point

I really have no idea why the didn't put a touch screen on it, works great for the GX7...

In reply to:

Felix E Klee: In a professional context, for example for fashion photography in a studio, what is the advantage of a medium format camera today?

Today's full frame sensors and optics provide more than enough resolution for even very large printed ads, and dynamic range there is plenty as well. Furthermore, in a studio environment, I expect lighting to be perfect and the pro photographer to frame close to the final result.

For landscape photography medium format is interesting, but that's not my question.

You really do get that extra detail from an MF sensor/lens combo though: http://i.imgur.com/RZzPCx4.png

In reply to:

kadardr: Nikon 1 J4 double lens kit is $546 right now. It is better than this and has a 28-295mm reach.

But the Nikon kit lenses are only f3.5-5.6

In reply to:

Gesture: I like the way Panasonic is thinking with compact, integral EVFs.

Losing the built in flash is a bummer though, on my GX7 I use it more (in bounce mode) than I use the EVF.

In reply to:

jdh99: This is a shocking development and a blow to Sony's E mount. Mount adapters always degrade image quality. Consumers shouldn't expect to have to adapt the mount

It's not a mount adapter, it's an aftermarket replacement part. It doesn't look like Sony are using any adjustable shims on their mount so it should be the same precision as the original.

In reply to:

alenis: The Sony image was shot at F 5.6, 25.7 focal.
Canon's at F 4, 32.2 focal.
Don't these differences affect comparison? Why DP didn't take the shots at the same aperture?

As DPR said in another comment they test a lot of focal length / aperture combinations until they find the sharpest, and then go with that.

The different lenses obviously have different sweet spots.

In reply to:

Ontario Gone: Keeping in line with their Panasonic impersonations, I think they are releasing a mirrorless SLR type body that is fully compatible with their DSLR lenses, and they are calling it the HG4...

Sounds more like Pentax to me

In reply to:

aris14: 1/1.7 sensors would be just fine if the output is not counting more than 8Mps. Given, of course, fine optics and software.
Who really needs more?

If those enthusiasts print their work seriously (size >A4) a larger sensor would be more adequate...

You'd still lack the ability to have even moderately shallow depth of field at anything other than macro or extreme telephoto though
