I wonder if the 2.8 III will still have the same ridiculously stupid tripod collar design that destroys the lens barrel, and gets hopelessly jammed when the screw-on guides come loose.

armandino: Not convinced that the D5 is better than the 1DXII in its category. It should be a tie.

@mako69
The Canon 1DXII is a great camera, and actually has better IQ at ISO 50-100, but it can't even touch the D4s at high ISO's. The D5 wins at color saturation and dynamic range as well.

I edit and print a lot of high-ISO photos from 1DXI, 1DXii, D4S and D5 shot at no-flash indoor competitions like gymnastics, dance and cheer. I don't see any advantage the Nikons have over the Canon's under those conditions. In fact, I usually have to work more on the NIkon images than the Canon images before printing them. In addition, the Canon 1D class has better ergonomics than Nikon D class, and Canon CPS is better than NPS. I have owned both Canon and Nikon systems and those last 2 points really made it hard to love Nikon as a working professional. That being said, the D5 and Nikons latest glass (70-200 f/2.8 III in particular) are extremely good, as expected for that kind of $$$

interesting. What are the purpose of those contacts? A google search led me to Halloween sites selling White Block contacts, which look similar but make the Iris look white, which these don't seem to do. IN any event, the clarity of the eyes in these photos is pretty spot on :)

The LED light panel(s) they are using does horrible things to the model's iris!

hidden1: At what point does a photograph ceases to be a photograph and becomes a computer generated rendering?

Easy to answer, it was the day you stopped using film! Every pixel in every digital photograph you've ever taken goes through a computer algorithm that manipulates it before it gets stored on your memory card. Even if you are shooting RAW.

Frank Neunemann: OK, but what is "Deep Fill" actually good for? Even more phony photographs made easy...

My #1 use for content aware fill when an 8x10 or 5x7 crop cuts off parts of the subject!!! Its an massive time saver. A better content aware fill will be even more of a win.

rev32: I remember 8K tape reel to real drive, punch cards, ticker tape and felt that was a lot...
It's amazing, wonderful and makes me feel old..

My Radio Shack TRS80 could store about 1k of data in approx. 30 minutes to a cassette tape given that it usually took 5 tries to get it to successfully save the data. Still a heck of a lot faster than re-typing the data back in :)

Franglais91: A NAS is a shoebox attached that you stick in a corner somewhere attached to your home/office network that you use to hold your files fairly securely i.e. if a disk goes down then you don't lose your files because there's another disk that has a copy of the data.
- It's like the Cloud except that access speeds and volumes are much greater/faster than the Cloud
- Like the Cloud it's NOT a backup solution. If you delete a file by mistake it's gone

I have one SYNOLOGY NAS for my precious data and another one to backup the first NAS. Plus I also have a second backup of the NAS on external hard drives stored in a facility 50km away which I refresh every 3 months (I live next to an air base with helicopters overflying every day)

That is only true for the most rudimentary NAS. Not only does Synology offer time backups, allowing you to go back in time for each file but since DSM 6.0 they also have snapshot. Snapshots allow you to restore your drive (or single files or folders) to any point in time. And that WITHOUT the need for a backup drive. You could not ask for more convenience.

That said a single storage device/ solution can never be a backup for other reasons. But that's the great thing with modern NAS/ Server / PC. If you set them up correct you can't delete a file by mistake

>>>This is great until UNTIL all the drives in your Synology Raid 6 array decide to simultaneously fail because they are "old" (straight out of the mouth of Synology tech support). The odds of this happening are staggering, but that's Synology's official explanation.

When this happens you have a big expensive paperweight and not a single byte of data unless you have backups of everything.

Was a happy Synology customer for years until my UPS powered Raid 6 array went belly up. Synology tech support looked at my box remotely and told me that all 5 disks in my Raid 6 array failed simultaneously because they were "old"!!!!

PhotoUniverse: I've had Synology NAS device (5 drives) for more than 6-7 years. and it's running with no problem 24/7.

Best NAS device in market hands down.

Word of caution, My DS1010 was running a 5 volume raid 6 array for years without issue until it decided to wipe out all 5 disks simultaneously one day. Synology support log on to my unit and suggested because the disks had been running for 5+ years they all decided to fail at once at the exact same time, all wiping out the tables necessary to recovery my data. Note that none of the drives actually failed, they just all decided to wipe out their drive tables at once. Never heard such a crock of sh*t in my life. Then I did a search on Synology problems and gee whiz a lot of Synology volumes have gone belly up out of the blue, just like mine. Note that my DS1010 is connected to a fairly expensive UPS, so I'm pretty sure I had no power issues going to it. I also have a 5 disk expansion connected to the DS1010 with its own 5 drive volume that still works fine to this day. Never had a problem with it.

Steve Balcombe: I have a DS413j which has run without issue for over 6 years. It runs quietly, the software is comprehensive, easy to use and easy to update, and it sends me an email once a month to reassure me all is ok. Highly recommended.

mablacksv: Verizon is offering to upgrade my current phone to the Z2 for $360 ($15/mo for 24 months). I was interested until I read no headphone jack. The couldn't give this phone to me for free without a headphone jack.

I have a hard enough time keeping track of my phone (which I can make ring to find it), never mind a stupid adapter.

In reply to:

Full Stop: .
It would be smart if SONY made all the "important" lenses one stop slower
than CaNikon.
50% less weight, cost, size (volume).
With a
24-70mm/4,
70-200mm/4
300mm/4,
400mm/4,
600mm/5,6
they would have a REAL weight- & size-advantage.
50% less light should be no problem for this new sensor.

The whole system would make more sense.
Perhaps even attract some µFT guys as the A9 itself is the size
of a GH5 / EM-1 Mk2.

Canon already has many of the 1-stop slower lenses you mention plus the wider aperture versions as well as IS and non-IS variants. For instance Canon has 4 different 70-200 variants you can buy depending on your needs and wallet: 70-200 f4L IS, 70-200 f4L non-IS, 70-200 F/2.8L IS, 70-200 f/2.8L non-IS

Also, wider aperture versions are still widely used for IQ unrelated to ISO. With my 1DX II sensor I never need f/1.8 to lower my ISO but still shoot with my 200 f/1.8 every chance I get because of its stellar IQ, narrow DOF, and gorgeous bokeh.

Sony has a very long way to go to catch up in the lens department.

Canon A-1 which I bought in Biddeford, Maine at ABE's of Maine (which is still called ABE's of Maine but is located in Brooklyn, New York! Go figure).

Loved that camera.

In reply to:

DualSystemGuy: I may have missed it but I did not see anything about:

1) The laundry list of things that will slow down the FPS (2 entire pages in the manual dedicated to scenarios where you won't get advertised FPS)

2) The AF is only -3.0EV sensitive at the center point in single shot mode, where few people use it. It drops to -2.0 for tracking scenarios, which is half as sensitive as the competition in the middle and one third as sensitive on all other points.

3) 1DX batteries do not allow for advertised FPS - you cannot re-use your old 1DX batteries without crippling the camera

Those are important pieces of info for perspective buyers IMHO. Otherwise great review.

I shoot mostly JPG's, and usually to fast CF cards. Given that the high ISO is so superb I'm usually shooting at shutter speeds of at least 1/800 even indoors. With those parameters I rarely if ever see anything below 14fps. I have 300,000 clicks on my 1DX2 so far.

Also, I think 14fps is really pushing the boundaries on what is possible with a dSLR. I think you have to get rid of the mirror to improve on that. It took Nikon 4 years just to catch up with the 1DX's 12 fps. And 10fps was the gold standard for a long long time before that.

I have 5 1DX batteries and a bunch of Mark IV batteries as well. I would have rather not purchased another 1DX2 battery too but the 1DX2 battery last up to 8-9 times what the CIPA tests rated them, and you really only need 2 to shoot 14fps all day long.

For the $6500 price of the D5 you could pickup the 1DX2 and 3 more batteries. And you could use your new batteries in your old 1D cameras which will make them run even longer.

In reply to:

donsdavid: I saw a review on youtube a few months ago claiming that the neither the Canon 1DX Mark II nor the Nikon D5 can focus at -2EV. https://youtu.be/sT14RrsDW18?t=554
Maybe DPR can check this out too as part of the AF review.

In my experience, low light AF with the 1DX2 is beyond stellar. I have been able to instantly lock on subjects faces where it was so dark I could barely make out their faces to begin with. Not sure what EV value that was but I was shooting a crazy high ISO (>50000) at f/2.8 around 1/125 sec. YMMV. I can't imagine needing more low light capability than this.
