darngooddesign: Since the new Monochrom is the the only Leica that causes this problem it is logical to assume there is something nona-standard in it's DNG files.

So, the real question is whether Apple had access to one of the cameras, or even Monochrom-produced DNGs, before the current version of Photos shipped.

But yeah, Apple bad...rabble rabble rabble.

If a computer program damages data when fed unexpected input, it's a bad program. Period. Apple's software should either:

1) Work properly with the Leica files;
2) Throw an error message saying that the format isn't supported;

or maybe

3) Misinterpret the data in the raw files and display a corrupted image, but not mess with the whole catalog.

It very certainly should not explode and wreck other data.

In reply to:

ttran88: They could have possibly reused d7100 samples and call it a day.

The Toshiba sensor in the D7100 is fantastic, though; it seems like we're spoiled for good sensors these days.

On Nikon D7200 First Impressions Review preview (1114 comments in total)
In reply to:

lorenzo de medici: It's an incremental upgrade from the D7100, which I owned and then sold. Aptly named, and the improved buffer and low light focusing will be appreciated, I'm sure. DX Nikons just don't have any place in my camera bag any longer. Wildlife shooters who need 750mm equivalent focal lengths will enjoy this camera quite a bit, no doubt. Sorry but I don't care what claims they make or what DPR says, since it has just become a marketing arm of Amazon. DX sensors can't get the job done when it comes to the edge of the performance envelope. Buy a D750. If you dig down to the bottom line of DX advocates, no matter what they claim, the bottom line is they can't afford FX bodies or FX lenses. Cameras with little sensors are just a cheaper alternative to the real thing. Period. In ten years we'll all be shooting mirrorless full frame cameras, and DX cameras will still be what they are now - consumer grade equipment.

The giant pile of magnificent wildlife images in the Smithsonian Museum of Natural History, printed six feet tall, disagree with you. Many of these were shot on DX sensors, even back to the D300's 12MP. The D7100 (and presumably D7200) sensors destroy that one in resolution and noise.

Looks like a Canon version of the Nikon 80-400G. That Nikon is an excellent lens so if Canon's lens wonks are as good as Nikon's, it should be a good thing.

I wonder how the AF compares to the system in the D7100, the closest thing Nikon makes? AF speed and accuracy, more than anything else, is the killer feature for the sort of action work that this thing is designed for.

On Sigma announces two 150-600mm F/5-6.3 DG OS HSM zooms article (138 comments in total)
In reply to:

DVT80111: There is no fun carrying heavy and long lens. Why haven't anyone designed a long tele-lens just for APSC to reduce its size and weight. Most birdly people use APSC camera anyway. Why do we have to pay and carry extra weight just for the lights (2/3 of them) we don't capture?

It doesn't work that way: normal and wideangle lenses can be made substantially smaller for APS-C, but telephoto lenses for APS-C and FX are basically the same.

On Ricoh announces Pentax XG-1 superzoom article (205 comments in total)
In reply to:

W5JCK: Super yawn....Another camera with a small sensor and little to offer. Putting a long zoom on a lackluster camera doesn't make it good or make it worthy of being on this site. This kind of cheap camera is going to be bought by people who don't read sites like this, or they would know better. I'm not sure why DPReview still brings us information on these little sensor cameras or for that matter smartphone cameras. Maybe their newest members have been dumbed down to that level. This used to be a site for enthusiasts and professionals, not so much now...

I have a 20" print on my wall taken with an eight-year-old small-sensor superzoom (Panasonic FZ50) that looks *fantastic*. I shoot Nikon DX now so I know what modern large sensors can do, but these small sensor cameras -- at base ISO -- can deliver some very impressive results.

Don't insult someone else's tools because they aren't as expensive as others; look at the results. Are there limitations to small sensors? Certainly. Can they be worked around? Sometimes, they sure can, and the results are not half bad.

On What is equivalence and why should I care? article (2130 comments in total)
In reply to:

rfsIII: There must be an professor of imaging science out there somewhere who can be hired by DPR to write a nice counterpoint article that will untangle this topic and bring sanity to what is essentially a holy war between two under-informed camps. I would start at http://www.rit.edu/cos/optics-rit and work westward from there.

@Bustard, it really is that simple -- I don't know why people try to overcomplicate this beyond what you have just described.

In reply to:

sdh: Does RAW actually offer benefit in smartphone-size sensors?
RAW has real benefit with DSLRs and regular point-and-shoot type cameras because the image sensor can capture a larger range of information than the jpg format can store.
But the margin decreases as sensor size decreases (decreasing dynamic range).
Do smartphone sensors actually have headroom beyond what jpg can store?

And separately I can't help thinking that if you're fussy enough about your images to manually post-process RAWs (because there's no point shooting RAW if you don't) then you probably should be doing photography on a device with a proper handgrip and shutter button (ie a real camera even if only a compact and not a smartphone).

Yes.

Noise reduction is crucial on data coming from a tiny sensor, and that can be better done by a 35-watt Core i5 in a few seconds than by a smartphone CPU running on a few hundred milliwatts in a few tens of milliseconds.

On Olympus OM-D E-M10 Review preview (342 comments in total)
In reply to:

MikeStern: I returned my A7r for the oly em1. And I am sooo pleased with this decision.

Some here talking about m4/3 vs. apsc vs. full frame. I would rather concentrate on olympus rather than m4/3 in general. Because 5 axis ibs is out of this world. 3 axis is also very good. And it's not just my opinion, everybody who try it will agree with me.

I have not taking a single blurry picture yet. Including 1/3 of a second exposures.

It's 300 f/4, isn't it? That's what I'd rather have anyway.

If I'm able to sell my D7100 + 80-400G for E-M1 + 300 f/4 + 1.4x TC, I will definitely consider it.

I have a close friend with CF who is an excellent photographer -- and, thanks to modern treatment, lives a pretty normal life. He's even a good singer, something that would be unthinkable not too long ago.

On Ricoh to offer limited edition Pentax Q7 Premium Kit article (88 comments in total)
In reply to:

Smokymtnhiker: Check out the Studio scene for the Q7 before ragging on it.

Look at the page of text lying under the bottle of Baileys. You can actually read the text on the Q7 shot which is something you can't say for either the D7100 or Fuji X-Pro1. Text does look better on the X-100s though.

So the Q7 isn't bad for an over-priced little toy after all.

Shooting a D7100 at f/32 will degrade the image due to diffraction exactly as much as shooting a Q7 at the aperture that achieves the same depth of field.

That's because the Q7 has so much more depth of field at the same f/number because of the bigger sensor. A D7100 can be shot at f/32 to get the same effect.

In reply to:

jon404: I am shocked at the low pricing for this excellent camera -- and for those from other mfgrs -- and also how fast the value depreciates. Scary, scary business. Great times for the consumer, but you wonder how much longer this can go on.

If Pentax made the lens I wanted (a 400 f/5.6) I'd have gotten one in a heartbeat. When it comes to the camera itself they seem to consistently get all the features right.

On Olympus OM-D E-M10 Review preview (342 comments in total)
In reply to:

techmine: Don't Samsung/Fuji/Sony (MILC line) provide better alternatives?

Perhaps they make better cameras. Olympus makes great lenses, and that's sort of the draw of Micro Four Thirds. Just off the top of my head, the lenses that are known to be quite good:

7-14/4, 9-18/4-5.6, 12/2, 14/2.5, 20/1.7, 25/1.8, 25/1.4, 12-40/2.8, 45/1.8, 45/1.2, 60/2.8 macro, 75/1.8, 35-100/2.8, 100-300/4-5.6, 75-300/x-6.7, exotic f/0.95 MF things, upcoming 300/4 and 150/2.8...

If you want to do it, there's probably a lens for it.

In reply to:

The Jacal: For any body who feels like whining about bokeh, or in case others may be taken in by the shills here, look at this:

http://admiringlight.com/blog/fuji-56mm-f1-2-vs-panasonic-leica-42-5mm-f1-2-nocticron/

Admittedly, a cople of high end lenses, but the same difference is the same at all levels between the two formats.

The go-to affordable portrait lens on m4/3 is the Olympus 45/1.8, which is a few hundred bucks. It is wicked sharp wide open and gives nice bokeh.

What else do you want?

Olympus IBIS has always been quite good (all the way back to my first DSLR, the E-510). I agree with your assessment of the E-M5; I rented one once and was blown away, and would probably have one if Olympus made the telephoto options that I wanted. It just does so many things right.

Nikon VR has caught up, though: I can handhold 1/30s at 400mm with the 80-400.
