NumberOne: Personally would rather be pilot than photographer on occasions like those - Even being 4WD and icy... :)
...As for the responsibility towards future generations I guess the complainers never used airplanes and other modern transportation means, among other; maybe they also don't buy consumer products and just live naturally in the jungle! :) :) :)

Here (small town in central Finland, about 62° North) most roads are currently covered with ice and snow. Driving is, eh, interesting, also with an old car like mine with no fancy computerized anti-skid features or ABS brakes. A modern 4WD with all bells and whistles would make it boring. :-) Not sure about photogenic...

LDunn1: Please shoot a (clear) night sky wide open for approx 30 seconds with this lens on a full frame sensor. I'd like to see how it renders point light sources (aka stars) towards the edges/corners of the frame.

I was excited with the announcement of the Sigma 24 f1.4, but then I saw a review which included a point light source in the corners & edges shot wide open & I was a bit disappointed. I'm hoping this 14mm performs better with such things than the 24 appears to.

For me the primary use for this lens would be aurora borealis, and with them 5 seconds is more typical - and that's where the wide aperture would really help as it'd allow using lower ISO sensitivity.

But nonetheless a 30 second exposure sample of stars would be useful for assessing coma.

In reply to:

Boeing skipper: Very impressive.
Would love to see a night sky shot at f1.8 to check the coma.

For night photography there's never enough light, even though it is indeed done with tripod. Stopping down means exposure times grow, stars become trails, auroras become blur... The only point of this lens is speed, and if you need to stop down to get rid of the coma I'll rather go with Samyang/Rokinon 14/2.4.

In reply to:

mikeyL: A lot of folks (like myself) are very interested in lenses like these for nightscape photography. Sure would be nice if you could include one or 2 tripod mounted star field shots of short enough exposure to not trail the stars so we could evaluate the coma of the lens in the corners.

Yes. Coma is definitely critical for me, too. If it isn't at least as good as Samyang 14/2.4, it's a no-go, regardless of anything else. So, can we have a star shot - pretty please?

Biological_Viewfinder: The case should be thrown out of court for being frivolous. I don't care what happened; she's asking for $2.2 Billion and therefore the case should be dismissed on the basis of it being frivolous. It's stupid and I'm tired of the games. If there's ZERO chance she could get $2.2 Billion; then drop the case until she gets reasonable.

Secondly, why is the restaurant being sued? Wasn't it the photographer who did the actual "damage"? Sue the person not the deep pockets. Again, frivolous and needs to be dropped. If anything, she should be fined for bothering the public with her nonsense.

Do you have a reference to that "less than $300k" in the McDonalds case? Wikipedia says the court actually awarded her $640k (judge overrode jury's recommendation of $3M), it was appealed by both sides but settled out of court for an undisclosed sum, and there is no suggestion it was insufficient for her medical costs.

"Freezeproof to -10°C" sounds a bit silly. (It's -22°C here in central Finland now and getting colder.) Fortunately most cameras can generally handle much colder temperatures than they're specced for (Canon 7D had no trouble at -30°C for example).

CameraLabTester: The Piranhas are going wild on the tasty morsel that just dropped in, for 2 weeks.

This could happen on just about any country with the same Laissez-Faire attitude to crime, peace & order, justice and police protection.

In this situation, however, a stampede of delicious Holstein Cows just charged into the river.


Brazil as a whole is not really all that dangerous. Big cities, especially Rio and São Paulo, sure (though I've walked around in both carrying SLRs without incident), but countryside and smaller towns are generally pretty safe (with some exceptions, of course).

nua: Looks like the end of Sandisk...oh well just need to figure out what are my other options than WD!

I've got WD drives bought in 2008 still going strong, as well as several newer ones. Admittedly those are RE* series disks rather than the cheap stuff, but nonetheless it goes to prove WD can make pretty reliable disks - certainly better than Seagate in my experience (even if not quite as good as IBM/Hitachi).
Of more recent crop WD Red series have performed well for me, too.

In reply to:

pannumon: Great photos! A notice: in Lapland the days in winter are extremely short and in summer extremely long. This means that sun angle is low, and you get the golden hour for like half of the day (assuming that it is not cloudy, as it often is).

Autumn is great time for photography in Lapland, as you get separate autumn colors for the trees (not spruces though) and the ground vegetation.

Summer is a great time for shooting mosquitoes, you get them in every single photo whether you want or not (but there are less mosquitoes at the hills).

Mosquitoes only arrive after mid-June though. I go to Lapland every year in early summer, during first three weeks of June, when sun already stays up 24h but mosquitoes haven't arrived yet. Midsummer though, notably July, is recommended mainly for entomologists and others who like insects. :-)

In reply to:

Requin: How did you protect your gear from the coldness. Most "freeze proof" equipment goes up to -10 degrees Celcius. Don't you risk your gear going there in cold weather? I live in Finland and have broken a sensor already.

That is strange. I also live in Finland and frequently shoot below -20°C and never had any sensor problems. On one occasion I had my camera (Canon 7D) out for two weeks nonstop when temperature never rose above -25°C and averaged close to -30°C, without any serious problems (lcd display got dimmer, but recovered when eventually returned to warmth). One smaller camera had a problem with its clock resetting itself around -20°C though. I'd be really curious to hear how the sensor broke.

Lapland in winter is indeed magical. Regarding the difficulty of using tripod in snow: I've used plastic plates attached to tripod legs as sort of tripod-snowshoes - in certain kinds of snow they work fairly well.

In reply to:

star shooter: Not having a tiltable screen like the 60Da has, is a bit daunting if you are imaging near the Zenith and have to get down on all fours to look at the image. I use an USB connection to the PC, control my exposures.

The biggest factor in any camera is the 'noise' that builds up as the sensor gets hotter. So unless you are imaging at temps no more than 20C or lower, no matter what Iso you use, the image will take on noise. But, having a FF sensor this may not be a problem. Either way, I'm getting one.

My 60Da has been doing great for over year now and if the D810A can match or do better, then its winner no matter what others say. Let's see some test images Nikon!

"The biggest factor in any camera is the 'noise' that builds up as the sensor gets hotter. So unless you are imaging at temps no more than 20C or lower, no matter what Iso you use, the image will take on noise."
Fortunately that's not so problematic here in Finland, where astrophotography is mostly limited to winter anyway (summer nights aren't dark enough) and temperatures are more likely to be -20°C than +20°C. :-)

kpaddler: "Not built for extended use in cold conditions"

As usual, DP doesn't disappoint with its useless points raised.

The camera lasts in cold weather longer than the people who carry it.

My old Panasonic GX1 sure failed in cold well before I did. First to go was its clock, which reset itself already at around -20°C (-4°F). Also, small cameras are generally hard to use when it gets so cold you need to use gloves, let alone heavy mittens - but some are harder than others (for example, I found Canon G11 surprisingly easy to use even with mittens on, despite the small size of some of its buttons).

You can also use the * button instead of shutter half-press. That is, have one zone in AF-ON and another in * and shutter doing metering only. Or AF-ON for zone and * for 61-point, or vice versa.

Unfortunately it doesn't seem possible to have one zone in AF-on, another in * and a third one in shutter half-press. That could be quite useful: separate buttons for left, center and right zone.

In reply to:

christiangrunercom: Why is the Ricoh GR left out ? It would have nuked all the others...

Incidentally, I chose the GR over X100S not because of the focal length difference but because the GR fits in my pants pocket and the X100S does not. I think DPR seems a bit too obsessed with focal length and zoom as camera selection criteria.

In reply to:

Harold66: This is a misleading title for a list of cameras which does not include ricoh GR, Nikon A, sigma dpm. I have seen the reply from dpr but if this is high end what becomes of these cameras not listed : super high end ??

The only reason I can think of for excluding Coolpix A and GR is that they lack zoom. But there are many people, especially among those looking for high-end pocketable camera, for whom that's not a key criteria, certainly not over image quality.

In reply to:

sbansban: Will Nikon Coolpix A and Ricoh GR be included in the high end pocketable compact category? As far as I know, at around $1100 and $750 respectively, these two are the absolute top pocketable (or near-pocketable) cameras that money can buy.

Seconded. I wanted the best camera that I can actually carry in my pants pocket, period, and settled on Ricoh GR. I really can't see why it (and the Coolpix A, which differs from it mainly by ergonomics) are not "high-end enthusiast compacts", although arguably they would fit in the pocketable compact category as well.
