Polacofede: Hi,
I know that this might add lot of work for reviewers, but i wonder if there could be other kinds of AF-C done when reviewing a camera. I mean, for instance when you shoot BIF or wild animals they usually move ( fly / walk / run ) in a more perpendicular or diagonal way to the camera lens and not towards the camera, and they are not at 1-2 meter away. So maybe you can arrange something to test this kind of focus tracking in a predictive way, you could also add obstacles like branches so the object goes beyond them and then re-appear and see how camera-lens responds. So IMHO the review could distinguish among those instead of AFC review conclusion been almost a binary conclusion. You could end up having a AFC testing ground :) .

I see your point. However, we've settled on the bike test (which has two aspects: a simple approaching object and then a weaving object to test tracking), because it's a semi-challenging test of two aspects of autofocus that we've found relate well to a variety of real-world situations.

Birds in flight, where you have a single object, very distinct from an effectively infinite background, isn't especially challenging for any phase-detection system - especially if the subject moves perpendicular to the camera, requiring minimal refocusing. We could create a test for that but everything we've shot suggests that all PDAF cameras would do very well at it and CDAF cameras wouldn't (something we should probably more consistently make clear in those cases).

The bike test isn't *perfect* and it doesn't represent every use-case. But it is highly effective at distinguishing between cameras that are capable in a range of situations and cameras that are more restrictive.

Gesture: If I could get 80 percent of the quality of a Rolls Royce, Ferrari, whatever for 1/2 the price, I might consider it Golden?

Also, UHD 4K is twice the resolution of 1080/Full HD in each direction. This means you're perfectly (2x) oversampling the image. This should allow downscaling in such a way that you display the maximum resolution that 1080 can possibly show, but with no errors and if done properly, no attempt to (erroneously) represent anything above 1080 lines per picture height.

So shooting 4K for playback at 1080 gives you the ability to:
Crop/Pan/Ken Burns
Digitally stabilize by taking a steady letterbox out of the larger frame
or just show better-looking 1080 by oversampling

And if you've got a decent editing package, it'll let you work with proxies, so you computer doesn't need to be significantly more powerful (it only edits the full res footage at the end).

PKDanny: Pentax K-1
Mid Range Full Frame Camera

Why they say Mid-Range??? Not High-End??

We have two choices:

Categorise it by feature-set and then get complaints that we're unfairly scoring it in relation to *much* more expensive cameras.

Categorise it by price so that it's scored in relation to the other cameras someone might consider at that price, then get complaints that the *naming of the category* somehow demeans the camera.

That's one of the easier decisions we have to make.

In reply to:

Al wants a bagel: I think people are still angry after the debacle that was the pixel shift test. And I don't know why pixel shift is a con in the first place. That's like saying all Fuji cameras are bad because raw developers for X-Trans are still wildly inconsistent, and in some cases, not supported. And it's uses are limited, that is clear, but isn't that something that should be a plus? That they offer pixel shift should be a bonus, not derided as a feature that cannot be used in some cases.

Deriding the menu system and AF points selection? That is awfully subjective. I've found that over time, those have become second nature, and with so many features available at the press of an actual button, easily I find this camera to be more user friendly compared to my D750. And yes, there are many useful features in this camera not available on the D750. Like the outdoor view button, that button has become invaluable for outdoor shooting in my experience. So is having a dedicated GPS and WIFI button also.

Pros and Cons are not all created equal. **Pro**: Great Image Quality, **Con**: Lack of WB fine tune in Kelvin setting, wouldn't cancel one another out, for instance.

The Pros and Cons are a list of things that we think potential buyers might want to be aware of. Nothing more.

Pixel shift is listed as the second 'Pro' in the conclusion (and has been since the first draft of the conclusion was written). This isn't nullified by us also pointing out that there are some limitations to its use and your subsequent processing options.

We trust our readership to assess how important each pro and con is *to them* and their way of shooting.

darngooddesign: Can anyone verify that the X-T1 Lensmate thumb grip fits the X-T2 (my Pro 1 fits my Pro2).

My guess would be no: since the X-T2's grip is slightly deeper, but I've not seen this particular accessory so can't be certain.

In reply to:

BfSkinner: Does the use of the LCD "live view" screen result in reduced focusing speed (or effectiveness)?
I'm referring to still photography...not video.
As I recall, the D7100 "live view" resulted in reduced performance.

Yes. Virtually all Nikon's lenses were designed for phase detection, so don't always react well to being driven back and forth in the tiny steps required by contrast detection (the system used in live view mode).

garyknrd: I would be careful with the AF claiming to be much better. I used the new pro2 a few weeks ago with the 100-400 and it was a dog to put it mildly. Compared to a DSLR.
I am desperately wanting to go mirror less but the AF has to be up to snuff. I am hoping DPR will put out a detailed AF review.

Yes, I hope we were clear that these claims are untested. It's certainly something we'll test in detail.

Light Pilgrim: I was waiting for 2 years for this camera, but for some reason I am not over the moon. It is nice, for sure. I need to see the quality of RAW files and will decide based on IQ. Why folks are so excited about the joystick? I have in Canon for many years

In fairness, Canon's AF case modes are better than the three interacting parameters they had before, which required a booklet something like 64 pages long to explain.

Also, it's worth noting that Nikon now has two AF tracking parameters, rather than one, in the D500 and D5. This suggests to me that there was a benefit to be gained from just asking the user what was likely to happen.

Robert Garcia NYC: Sorry, I might have missed this but not one word regarding lowlight focus? Anyone spot that?

Fujifilm says it works down to -3EV, but our unit is pre-production, so we haven't tested it.

Brianroger: Well written as always Richard Butler, but please FOREWENT the hybrid viewfinder? Eschewed surely? Rant over, enjoying your wise and balanced reviews and first impressions.

Thank you, both for your kind words and your probably better suggestion of wording.

I took 'eschewed' to mean it *deliberately* went without it, rather than that it had to make do without. But 'Forewent' is probably a bit much. ;)

Kiril Karaatanasov: This battery life thing is complete fake. I took 800 shots today on my A6300 with single battery and had 41% remaining charge. I would bet I would be able to do similar with Fuji......I all depends how you use the camera. Mirrorless with full electronic shutter just use much less energy than DSLR.....I could have easily gone well beyond 1000 shots

The best way to think of it is like fuel economy/gas mileage figures: they don't necessarily tell you how many miles you'll be able to drive or how many shots you'll be able to get.

However, they do give a very good idea of how one product is likely to compare with another. So a camera rated to 600 shots per charge is likely to last around twice as long as one rated at 300 shots per charge, if used in a similar manner.

jl_smith: So I did a short comparison between an X-T2 setup and a D750, since someone mentioned one could just buy a D750 for 'these prices'. Of course you cannot *DIRECTLY* compare FF and APS-C (insert equivalence blah blah blah) but I came close. Also, this is an older camera vs a new X-T2, so prices are skewed a bit.

For those curious - took the prices and stats from B&H:
D750 w/ 35mm f/1.8, 70-200 f/4, and 16-35
Price:$5017.85
Weight:2689g
bulk:215 in^3

X-T2 w/ 23/1.4, 50-140/2.8, 10-24
Price:$5096
Weight:2213
Bulk:162 in^3

So with the Fuji setup you pay 1.6% more in cost, for 82% of the weight and 75% of the bulk (volume) of the Nikon. Specs you all can compare for yourselves (video differences, OVF vs EVF, whatever).

Then there are the intangibles: control preferences, after-release support of camera, battery longevity, etc.

I prefer Fuji ;)
Others may prefer Nikon.

Good to have choices.

@The Davinator - it's *entirely fair* to compare an F4 lens on FF with an F2.8 on APS-C, because they offer broadly the same thing. There's no reason to demand the use of the same ISO across two cameras.

Yes, using equivalent apertures means the FF ISO advantage vanishes, but you are comparing two things that offer similar capabilities, at that point, rather than dictating that you can't buy FF without using its full potential (which yes, would cost more).

In reply to:

agentlossing: Looks like a nice pro-grade camera, as long as the pro doesn't mind using APS-C. That's a lot of money when combined with some of Fuji's better primes, but I guess you gotta find writeoffs where you can! I can't personally imagine spending this much, but then I'm not the target market, obviously.

There aren't likely to be huge IQ differences between X-T2 and D500, though the Fujifilm will have slightly higher resolution and nicer JPEGs.

It would be a huge jump for the X-T2 to catch the D500's autofocus, though.

In terms of video, it'll be interesting to see. The D500, with its 2.25x crop (relative to FF), is not exactly a great video camera.

damian5000: An AF point joystick...:/ how quaint. Welcome to 2006, boys.

The Panasonic AF touchpad system is really good (and we try to give it credit every time we encounter it). Though it must be said that it works better for right-eye shooters than left.

As a left-eyed shooter I don't believe that it's *so much* better than a joystick that we'd start to decide that one was unequivocally better than the other. We believe there's still room for personal preference there.

justmeMN: It's easy for a camera to get through the First Impressions Review. It's the following Second Thoughts Review that's tougher. :-)

Sadly, yes. Promises are one thing, delivering on them is harder.

In reply to:

thx1138: Is that VF magnification FF equivalent or is it APS-C and is actually 0.77 x 0.667 = 0.51x FF equivalent.

Also what is the weight of the camera, can't see it in the specs.

0.77x is using a 50mm *equivalent* lens, so it's directly comparable to FF.

Unhelpfully, CIPA now allows viewfinder mag to be described in terms of 50mm and 50mm equiv lenses, and it's often hard to work out which is which.

This is a huge viewfinder. ;)

Henry McA: They could have updadet the AE bracketing to at least 5 shots. The handgrip could have been a little bit deeper too. Still a nice camera.

It's +/-5EV for Exposure Comp, +/-2EV for bracketing, with the current firmware.

The Squire: Good early overview, thanks DP.

Could we get some more detail on the video specs?

H264. Check.
422? 420?
8bit? 10bit?

I think Fujifilm would be shouting from the rooftops if it was 10-bit.

422, 8-bit. 100mbps h.264 if recorded internally, unless you hear otherwise.

Our first impression are that it's not as detailed as the a6300's but it pretty competitive with 1:1 sampled 4K.

Presumably you're using MSRPs (so $2299 for the Nikon) for this comparison, so that you correct for that fact that one of these cameras is brand new and the other is probably half way through its life-cycle?

Greg7579: Why in the world are you describing the Fuji lens lineup as niche and attractive to a small dedicated following? Fuji lenses are the best in the world and that was the only part of your very good review that I took issue with. So that means you did a good job. I just pre-ordered the XT-2 on BH, along with the large handgrip.

https://www.flickr.com/photos/139148982@N02/albums

Greg7579 - I actually meant it to other way 'round: Fujifilm bodies have lagged behind other mirrorless brands in terms of C-AF and tracking, meaning they appeal to a niche who appreciate the often impressive lens lineup.

I was trying to say that a camera able to address the remaining weaknesses would make those lenses all the more appealing. I'll try to re-phrase it later, to remove that ambiguity.
