On article Special K? Pentax K-1 Review (2595 comments in total)
In reply to:

pentaust: I can see a lot of offended replies following the review of Pentax K1 AF performance. On the one hand some Pentax users feel offended from the poor review given to Pentax K1 AF performance. And DPR feel offended when their methodology is questionned. Well, every AF servo module is designed to perform best for a set of use cases. For example, Pentax Single Point AFC tracking is not meant to be used for tracking a fast moving subject such as a bike or car or motorbike etc... Single point AFC is used in focus prio mode to focus on slow moving target, such as at weddings, so, if you (DPR) got poor AFC single point results on a bike, you did not use the proper mode that is planned by Ricoh engineers. If you used multipoint AFC tracking and selection focus priority instead of FPS priority, you'd already get a lot more keepers. And if you'd use focus preset, your keeper rate would increase even more.

Rishi, you should know this by now. Any criticism of any product will bring out the fanbois in droves who will defend their product to the bitter end, no matter how bad it is. The K-1 scored higher than the 5Dsr. Both did not get gold awards and both are still very good cameras, albeit ones with flaws.

This is the internet and the era of idiocracy. Reasonable and reasoned individuals are no longer welcomed. :-/

oscarc: Nice politically driven contest. Makes sense that the photos with the most death and destruction would get the most attention just like in the news. Aside from this, pictures like these help promote the climate change/global warming hoax. Forget that satellite images show more ice than ever, or that the earth was actually cooling, hence the "global warming" label change. Never mind that "scientists" manipulated data to support their position. Pesky facts. And yes, there is politics in everything.

This thread really brought the drew the fringe element out of the woodwork.

@oscarc, if people are calling you *all* of those names, maybe they problem isn't so much with them as there is a problem on your end.

Typical of many dogmatic individuals to try to shoot the messenger rather than the message. The Bloomberg article just aggregates the relative charts to show the variance in sources so one can graphically identify the primary sources of global warming. Not everyone who is here lives in the US.

You could always start here:

Hard to change anyone who's inoculated themselves from science and reason but one can always hope that one can do their own math and figure out what is real and what is propaganda.

nicolaiecostel: I warned you, in the article that announced the purchase of SanDisk by WD, I said that they will interfere and mess things up, and you contradicted me.

Here is the proof !

I think you should put away your tinfoil hat. The merger of WD and Sandisk happened on Oct 21, 2015.

Check this page here:
http://www.bhphotovideo.com/c/product/1087556-REG/sandisk_sdcfsp_064g_a46_64gb_extreme_pro_cfast.html

First product reviews show up on November 25, 2014, almost an entire year before the merger. Maybe the WD ninjas dropped into Sandisk headquarters to pre-ruin this product because the Nikon time wizards wanted to mess with the Canon 1Dx2?

Fujica: Why Canon why?
Second BIG problem with the 1Dx MKII and playing the blame card is really poor.

IF this problem is caused by Sandisk then why oh why Canon do other cameramanufacturers NOT suffer from this problem?

Its really poor to blame others while the problem described more sounds like a buffer problem with the 1Dx MKII.

I don't think I've ever heard of :o))) meaning a joke emoticon.

I even tried to search google for this emoticon and I came up empty.

Nothing shows up here either:

Joe Ogiba: Canon should have used UHS-II SDXC slots. The 2000x UHS-II SDXC cards are very reliable and more than fast enough with much lower cost.
http://www.bhphotovideo.com/c/product/1191363-REG/lexar_lsd128crbna2000r_pro_2000x_uhs_2.html

If 800Mb/sec is fast enough then there would be no need for XQD nor CFast. The 1Dx2's 16fps at ~30MB is 480MB/sec and the D5's 12fps at ~43MB is 500MB/sec. Faster cards help maintain the buffer so the cameras can keep shooting at top speed. It's not a common occurrence but I've hit the buffer limit on my 1Dx and 1D4 occasionally.

photomedium: They are fixing it, it's all good. Anyways, sandisk cards are just fine.
No need for Canon to play the blame game.

@ AprilW,

I have no problems with my 1Dx2 and Lexar 3400x 256GB cards.

@Odpisan,

They are not even CFast spec cameras, and besides, Pentax cameras don't count anyhow. :-)

Minimum write speed guarantee of 30MB/sec. That is really slow compared to CFast (2.0). The Lexar 256GB CFast cards are writing in excess of 400MB/sec.

The 1Dx2 is way better with CFast, just some teething pains with any new(ish) standard.

If anyone had bothered to read the linked article you can see that they were basically hanging on since *1991*.

"The decay in the heritage institution had, however, started to set in much before the advent of digital technology. A fire in 1991 not only broke the studio financially, but also destroyed pieces of history stored in the building in the form of negatives."

On article Video: Canon EOS 7D versus leaf-cutter ants (47 comments in total)
In reply to:

James Benet: The reason they took the plastic and the other bits is because you left a sweat or smell imprint on it. The ants do not eat the leafs or insects they take. They hoard it deep into their nests and let it rot to grow a fungus that is their true food source. The plastic and other parts by having bacteria and human oils and sweat would also help in growing the fungus. As a nature photographer myself the water containers help but are just a starting defense. You need to use White Petrolatum or Vaseline in the tripod legs to stave them off as that is something they easily stick to and thwarts their advance.

I have a research scientist friend who trapped tsetse flies in Africa and they created a ring-like barrier around the steel legs with dollops of axle grease to prevent ants from crawling up into the traps.

1/4"-1/3" thick dollop all the way around each leg, about 6"-8" off the ground, and clear the area around it.

On article Canon USA launches new online photography courses (25 comments in total)
In reply to:

DamianFI: Make it free and a large chunk of customers who use it will most likely buy Canon products.

Charge them and they won't bother, you can learn it all on YouTube university.

Canon should charge for it but give certificates to everyone who has registered their warranty in the last 2 years and also with every new SLR/ILC.

That way it adds a perceived value to the course, and to the new camera sale.

nir-vana: I will take the Sigma 120-300/2.8 S
Similar image quality, less than third of the price, T2.8 vs T4.7

http://www.dpreview.com/galleries/1996031733/photos/2488317/a94b6560

Taken with the 1D4 and Sigma 120-300/2.8 OS in declining light. We were on a rubber zodiac slowly motoring by after the light had declined to the point where we had head back to the ship. ISO 5000 wasn't ideal for the time but I needed the faster shutter because of zodiac's bobbing and the how low the light level was.

Nobby2016: the lens elements show dust.

i worked for a video production company and i did such stuff as CGI in maya,
it´s a mess to do stop motion when you see every dust spot and fingerprint.

so as nice as it looks the dust gives me the creeps.
no way i could have presented that to my former boss.

they should have done most of it as stop motion but do the lens elements as CGI.
im pretty sure canon has full CAD models of this lens so they could have done it 100% animated easily. but i see the reason why they wanted classic stop motion.

it´s just that the dirty lens elements don´t look good.

Good eye...even the aperture blades after that show some wear.

I have the original 120-300/2.8 OS and the 200-400 IS. My 120-300 is a freakishly sharp copy, but the 200-400 is definitely better in AF and the built in TC means the lens is extremely versatile. Before the 200-400 I used the 120-300 on a 1D4 as a 'poor man's' 200-400. Now the 200-400/1Dx(2) is a near unbeatable combo whilst on safari.

If you need a zoom and can't afford the 200-400 I'd recommend the 120-300 Sport or the 100-400 II. There is an embarrassment of great lens choices today.

robbo d: Glad i'm not the only one finding that i'm needing to up my shutter speeds to get sharp images with this new breed of high mp cams ....

Higher resolution means that something that was sharp across one pixel might be blurry across 2 pixels if the new sensor is twice as dense (4x megapixels), if the subject is in motion.

Therefore increasing shutter speed would be the solution to freeze the motion even further.

In reply to:

alcaher: There was a d5/1dx msrk2 Af performance comparison, it was interesting. I want to see from dpreview a d500/d5 Af comparison too.
Like a previous póster said, eventhough they share the same Af system and technology, the d5 might be better but how much better?
People here like alot comparisons between cameras of different brands, well it is time to see some between the same camera maker.

I think you're right in looking for a D500/D5 shoot off comparison. Even though they may share the same AF sensor, all the subsystems after that are significantly different, although it may wind up to be a small advantage for the D5 in the end.

I don't have a D5 but I do have a 1Dx2, moved from 1Dx and all the 1D series since the II before that.

I'd say that Nikon has tended to have the edge in AF performance in previous generations and I think they still may at present, but the gap has been the narrowest since the D3 trounced the problematic 1D Mark III.

The D5 might be better in the lowest light (high ISO and AF) but the 1DxII is just behind it. However, faster FPS, base ISO DR and 4kp60 video are really strong features that make the 1DxII a better all around body.

Also Canon battery life has been slowly going backwards on the 1D series while the Nikon's have been going forwards.

It would be in the narrowest of edge cases where a Nikon shooter would have gotten significantly better results than a Canon shooter, and other improbable edge cases where the Canon shooter would have an advantage. I wouldn't hesitate picking a Nikon or Canon 99.9999% of the time.

In reply to:

johnschafer: I'm sorry, but I'm at the point where I'm done with DPR's very obvious Nikon bias. I really don't want to start a negative rant here. But come on, honestly, I must protest. DPR admits in a separate article of the D5's lowest base ISO dynamic range of any current FF Nikon DSLR. Further, look at FStoppers review of the D5. It is very clear to see the D5 hits its useful limit at ISO25600. Here at DPR if this was a Canon-equivalent pro DSLR, it would be demoted to Silver award. Further, DPR hasn't reviewed a Canon 1D-series in 6 years. Nikon D5 is a Silver award, nothing more.

Anyone who decides to buy a D5 over a 1Dx Mark II only because of this review (coming out first) is pretty much a fool for doing so. Both the D5 and 1DxII will not disappoint though, but which one you would choose would likely not hinge on a DPR review.

If there was a big bias towards Nikon vs. Canon you wouldn't have had Barney's cool 80D video (sponsored by Canon).
