" Darling where was this picture taken ? And this one ? Where was that again? "

So why is this GPS feature so neglected ? The DMC-GM5 (and others) would have been so much nicer camera in my list ! For that price, most people would expect GPS to be a standard feature or at least an option. Everybody might have it's own reasons, but on the subject I guess anybody will agree.

When showing your best pictures, what is the most common question you will get to answer ? .... " Waaow ! WHERE was this ? "

The Garmin GPSMAP 60CSx uses a SiRFstarIII GPS receiver, which for many years was the gold standard. It’s a 20-channel receiver, so it can download data from all visible satellites simultaneously, greatly shortening time to first fix (hence your 45 seconds).

I tried my Garmin nüvi on a TGV once (at 300-odd km/h). It took literally half an hour to get a fix but did eventually do it. Obviously I wouldn’t want to rely on it achieving that.

My phone’s receiver, like yours, is dramatically quicker and more sensitive. It also taps into the Russian GLONASS satellite system – how much that helps I don’t know.

Zerg2905: Dear DPREVIEW...
I read your reviews carefully. Because I think you have the skills, and the expertise, to produce quite good reviews. And many, many times, I was on the same page with you, especially when you pointed (rightly) the clear flaws some of the Canon cameras have. But not this time. I own the 7D 2. I had the 7D before, and between these two there is no contest. Sony sensors, ah, yes, they DO have more DR (but not that much). Other brands DO have more video mumbo jumbo (and big minuses in other areas). But the 7D 2 is, in my opinion, a photo tool, first hand. So tell me, please: which photo tool in the APS-C world is matching the 7D 2? The SLT A-77 II? I would have to disagree, as I have use it, too. Other brands don't have anything close, but, like the 7100, are "Gold award" cameras.
I think the Silver Award is a BIG MISTAKE (and many EU and US articles seem to be on my side here...), a mistake that will cost you credibility. Not now, but in the mid-long term. If it matters.

Flaws may be overstating it, but videographers had to work around many inconveniences – hence the rise to prominence of companies like Zacuto. And for stills, it lacked the speed and autofocus sophistication of its Nikon D700 rival.

But that 21-megapixel sensor derived from the eight-grand 1Ds Mark III made it all worthwhile for a lot of photographers, many of whom still rely on their 5D Mark II daily.

iAPX: I still don't understand how someone could spend so much into a camera and then use a non-calibrated iPhone display on it. Non-sense!

As DStudio says, iPhones are calibrated and profiled quite well when they leave the factory – likely better than anything made by a camera manufacturer!

Besides, precise colour accuracy doesn’t really matter on a camera display (and is anyway impossible to achieve in bright and varied ambient light).

On Pocket Watch in the Macro - Machine challenge (5 comments in total)

Mechanical timepieces are among the most astonishing, beautiful, and of course influential of human achievements. The idea that the oscillation of a balance wheel like the one in this photo could be regulated to a few parts per million by minute weights and temperature-compensating bimetallic construction is to me laughably audacious – and yet John Harrison’s marvellous chronometers achieved that already in the 18th century.

If you are mechanically minded, learning how these watches function will give you enormous pleasure.

ALPA cameras are uncommonly beautiful and well-made things. It’s worth visiting the ALPA stand at your next camera show just to check them out, though be sure to wear your best tie!

By the way, the 35 mm lens is variously described as f/4 and f/5.6 above. I think it’s the former.

In reply to:

WillWeaverRVA: EDIT: Never mind. The acronym "ILC" is confusing, though, as it's typically taken to mean "interchangeable lens compact" (i.e. a mirrorless camera) and not what it's supposed to mean here: "interchangeable lens camera".

The term ‘mirrorless’ is understood by everyone and rather apt. Like the horseless carriage (now car) and wireless set (now radio), it will disappear when the time is right.

In reply to:

JoEick: Why is it whenever someone makes a scene example of why DR matters, it's always a scene where bracketing could have been easily used? Is this an infomercial where people can't even use a normal spoon in their cereal without burning down their kitchen? lol

1. Bracketing can be used even with things moving fast through the frame. It's very easy to fix in photoshop without artifacts. The 7D2 is a fast machine that can bracket like a bat out of hell. It also has quick 2 shot bracketing.

2. Since when does having the Sun much darker than the shadows ever look good? Pushing shadows often results in bad taste long before bad shadows, regardless of sensor brand.

3. Shots taken at ISO 100 need to be processed as two different output files and then recombined in post for a good result. Pushing shadows over 3 stops while retaining highlights is going to force the software into HDR tone mapping mode, which equals HDR type artifacts and halos from dark to light transitions, which is crap.

“Pushing shadows often results in bad taste long before bad shadows, regardless of sensor brand.”

Ha ha! Well put.

The 7D Mark II is undoubtedly a fine camera, but I think DPReview gives out too many awards. Why should the umpteenth unadventurous iteration of Canon’s ancient EOS platform be worthy of an award?

The top award should be given to cameras that meaningfully change what is possible. Examples (not comprehensive):

• Canon 300D/Digital Rebel – a digital SLR for under $1000? No way!

• Nikon D70 – fast, capable, cheap

• Canon 5D – put full-frame (when that really mattered) within reach of determined savers

• Nikon D40 – imaginative new platform that really hit the sweet spot

• Nikon D3 – huge leap in refinement and core technologies

• Panasonic Lumix LX3 – too many reasons to list

• Canon 5D Mark II – despite significant flaws, changed the course of video

• Fujifilm X100 – gave control back to the photographer

• Olympus OM-D E-M5 – made Micro Four Thirds sexy

• Ricoh GR – billboard-quality photos in your pocket

• Panasonic Lumix GM1 – radical miniaturisation done right.

Et cetera.

Andy C Knight: Hi, I have a couple of questions on the GM5, that I was unable to find in the User Manual...

1. Is it possible to turn off the LCD and set the EVF to only turn on, when you put your eye to the camera? (I'm thinking of maximising the limited battery life!)

2. Can you MF with (10x?) magnification on the LCD/EVF with a legacy (i.e. non cpu) lens attached?

Many Thanks

Andy.

Nice! Thanks, lacix.

I have become obsessed with getting a GM5. Acquisitiveness run amok! It would be a small moral victory if I managed to resist.

I was going to mention page 167 of the user manual, but I see I’m too late.

I don’t know why this limitation exists, since the mechanical curtain is used with non-Four Thirds lenses when flash is used. But it’s not a serious limitation for me. There are perhaps better Micro Four Thirds cameras (e.g. ones with larger viewfinders for easier focusing) for habitual users of legacy lenses.

Besides, the electronic shutter should work fine for many things. The 10-bit limitation is there to speed up readout, so it’s considerably more usable than the GX7’s electronic shutter – which is itself anyway used by many owners.

Another question for lacix: how quickly does the viewfinder turn on when you raise the camera to your eye? The GX7 is much slower than the Olympus E-M10 in this regard, which bothers me slightly.

I’m no expert, but my understanding is that Assisted GPS downloads reference time, ephemeris, and almanac data for the GPS satellite network from a terrestrial server via the cellular network. Without this cellular assistance, a GPS receiver has to download this data at a very slow rate (50 bits per second!) from a GPS satellite itself. This can take up to 12.5 minutes depending on how much up-to-date information the unit retains from the last time it was used.

While phones do use cellular triangulation to give a rough position, that is a separate function from Assisted GPS.

Here’s a new GPS receiver that consumes just 10 mW:

www.sony.net/SonyInfo/News/Press/201302/13-022E

Its cost of 1000 yen is less than 10 dollars/euros.

Just now my smartphone got an accurate fix in 15 seconds – indoors and two metres from a window, outside of which is a tall building. On a city street it usually gets a fix in less than five seconds. Newer phones may be even better (I have an iPhone 5).

GaryJP: As someone said, the people who should be MOST interested in this sale are the Australian tax collectors. If it's bogus, he's going to have a hell of a tax bill to fork out for a bit of publicity.

He only has to show the statement was bogus or a piece of performance art in itself. The tax authorities won’t be interested if the $6.5 million only exists in his head.

Peter Lik apparently has 14 galleries in the USA, so I suppose it would be the American taxman that might be interested, if any.

Andy, you should know the GM5 resorts to electronic shutter, with the limitations that apply (e.g. 10-bit colour depth) when using a legacy (non-chipped) lens.

Andy, you must have tried it on an old smartphone. My iPhone takes a handful of seconds to get a lock, even in the city. It’s nothing like the old Garmin nüvi in my car or the Garmin Edge on my bicycle, which can take literally minutes to get a fix in bad conditions.

Furthermore, a GPS unit doesn’t have to use much power these days. (Moving maps on a big and bright LCD with maps downloaded via a cellular connection is of course a very different thing, but none of that is needed in a camera.)

A modern GPS receiver uses about 0.1 watts (some use one-tenth that!). With the GM5’s battery (about 5 watt-hours), a 0.1-watt receiver could be powered for 50 hours. So if you exhaust the battery in 5 hours of photographing, the GPS unit would only use 10 % of the battery’s energy in that time.

The technology is there (admittedly, phones use Assisted GPS which may be difficult on a camera). It just seems the market isn’t ready – which amazes me for the reasons Merel stated.
