On Video: DPReview panel at CreativeLive's Gear Day 2015 article (28 comments in total)

What I found interesting about this video was the discussion on 4K.
The panel were talking about how 4K might not be optimal for sport due to video needs wanting to capature at 1/50 or 1/60.

As a photographer, if the IQ from a 4K capture is there, screw 1/50 and 1/60.
Just shoot a 1/1000 or whatever and freeze the action.

Yep storage will be painful you'll be changing cards a lot, but once you have your shot ditch the select.

The 1/50 or the 1/60 are only problematic if you care about the video.

Pervert the tool I say.

Then your only problem is the aspect ratio.
But buffer dept goes away as a problem.

In reply to:

jtan163: Anyone know if Capture Pro 8.2 will allow for D750 tethered shooting?

I know it tethers generally, do you know if it specifically tethers with the D750?

In reply to:

obsolescence: The 40MP high res mode is the main feature that would make me want to buy an OMD camera -- I could fix the artifacts of moving objects by patching in upsized segments from outtakes in post. What I really need for architecture and landscape is a 17mm equiv. shift or tilt-shift lens, preferably one that's not too expensive (like Canon's is). I'll bet Samyang could build one.

Yes a tilt shift would be nice.
Be interesting to see how "pro" Oly go, i.e. if they will extend their system to include TS lenses.

A 17mm equiv and a medium tele with macro would be grand.
Especially if they could bring it in for less than say $1600.
All manual would be fine.

Adapting is OK if you want normal or tele FLs, but even 17 or 24 FF is far too long for a wide on M43. Although I suppose you could use a speed booster.
I must admit I haven't got around to trying my Samyang F mount 24mm TS on my EM-5 yet.

However I have to say the Samyang's optical performance (at least my copy) is attrocious up to ƒ/5.6 and only gets decent at ƒ/8. You want ƒ/11 on up to get good from it, even with the movements centered, so I think my copy will do poorly on M43 due to refraction.

emersonik: DPReview should educate its readers about the implications of higher MP count and to whom it would be useful.

If high MP were so universally important, why the kinds of 1Ds and D4s do exist?

And I'm spent.
For the rest of your education, hit the forums, and the search feature.
Look for stuff about the D800 as I think that's where the discussion really started in earnest.

High MP is not universally important in practical terms. Realistically in todays screen based world it is less important than ever except for a very limited user base.

As you suggest there is lots of evidence of that in the form of cameras like the 1DX, D4s, A7S and the M43s.

In marketing terms HMP is perceived to be important because in the early days of digital imaging e.g. when we had 640x480 pixel images, resolution was not high enough to view much detail, so higher MP counts were a very easy way to suggest that one camera was better than another - the so called mega pixel wars.

We are now at a point where for most people for most current needs the MP count is sufficient. Some people say 12MP is sufficient, other 16, other 24. But for most applications more MP is not necessarily useful or indeed percievable.
However in the early days we were trained that more MP was mo bettah, and many unsophisticated users stil look to MP as a metric for "better".

Then there are the on sensor implications.
For a given format of fixed dimensions to cram in more pixels you need to make the photosites smaller. This has implications for the number of photons collected and as I understands decreases the signal to noise ratio, theoretically at least and almost certainly practically reducing the IQ when compared to lower MP (bigger photosites) sensors using the same generation of chip technology and image processing pipeline.
(one of the likely reasons the A7S does so well in low light and high ISO).

HMP sensors are also more problematic in video, as video used fixed relatively low res formats. This requires line skipping or pixel binning to reduce to high res image to the low res image and often results in visual artifacts and lower acuity of the resulting video (one of the reasons the A7s has a low MP sensor).

The readers can educate themselves by reading existing articles and the forums.

Some high MP implications:

High MP (HMP) requires better technique and better lenses (than lower MP).

HMP creates larger files, which means more data has to be processed and moved, both within the camera and without.
In the camera the implications for more data needing to be moved include more cycles required to process an image and write it to storage, which has implications for frame rate.
The in camera data processing increase also has implications for buffer depth. A given amount of memory will be able to hold less HMP frames than a lower MP count could.
Outside the camera HMP have the same implications for your PP machine. They need more cycles, more storage and more memory. The storage requirement flows on throughout the workflow, to image distribution (network transmission time, larger physical media), backup, archiving and disaster recovery.

On Olympus OM-D E-M5 II Review preview (695 comments in total)

@DPR Staff any chance of writing a description of the points system and the Gold/etc award system and linking it to the pre-amble and conclusion of each review (or just link it if it already exists), so we can reduce (sadly I don't think we will eliminate) the why did such and such score X or Y comments?

I'll send you some cookies.

On Olympus OM-D E-M5 II Review preview (695 comments in total)
In reply to:

mpgxsvcd: I have one simple question. Why did the Canon 70D receive a MUCH higher score(83 vs. 81) and the Gold award? What does the 70D do that the E-M5 MK II doesn’t?

If I picked up the 70D right now and shot it side by side with the E-M5 MK II what would the 70D be that much better for? Both cameras are still at a similar price point today and they are in the same category. So what makes the 70D so much better?

Is the issue that the 70D was rated against the competition of 2 years ago and the E-M5 MK II is rated against the competition of today? Shouldn't the ratings value always increase if the cameras are always getting better? Why are cameras like the A6000 and the E-M5 MK II rated lower than the 70D?

I still cannot fathom why I should choose a Canon 70D over an Olympus E-M5 MK II. If I purchased solely based on your conclusions and ratings then I could see no other option. Thankfully, I didn't wait for the review and bought the E-M5 MK II sight unseen. I don't regret it that one bit.

The Gold/etc awards are not related to points they are given more subjectively.
Furthermore scores and ratings are as far as I know given based on comparisons against other cameras in the same class at the current point in time.
This has been re-iterated a number of times by DPR staff, but it would be helpful if the methodology was linked to in the pre-amble and conclusions of each article, so we didn't need to have this discussion EVERY review.

I personally would suggest you should choose whatever camera you like based not on DPRs reviews or awards or any other single source of info. I'd also personally suggest that waiting 6 months or so after release would be prudent to see whatever bugs come up and the manufacturer's response.

Glad your punt on the EM5 II has worked out well for you. Looks like a nice camera. Wish I could both afford and justify an upgrade from my MkI.

In reply to:

Kameo: Can someone elaborate on this line (in the above review):
"...lack of on-sensor phase detection means it's less well suited for use with existing Four Thirds lenses..."
Is this similar to DSLRs' built-in focus motor?

To clarify further the EM-1 has PDAF sensor built into it's sensor.

Rick_Hunter: So, let's make a checklist
- people who buy an ultrawide lens wanna go wide: the nikon is significantly wider
- the nikon can take filters (even though cumbersome and expensive) trough third party solutions - the tamron can't.
- you're sure to have compatibility with all future bodies with the nikon, not so much with the tamron
- you're sure to have more resale value with the nikon, certainly not so with the tamron
- the nikon is smaller and lighter (and probably better built, knowing tamron...)
Rave all you want, but the nikon still looks the better purchase. The only plus for the tamron is a little bit more center sharpness which I highly doubt you're ever going to notice in prints...

@Lassoni - I very much agree. The 3rd parties especially especially Sigma and Tamron are very much catching up.

I don't think the 3rd parties are completely there yet in all respects, but I think it is very hard to make a rational un-emotional argument against their value proposition and the differences are such that only the denizens of places such as DPR would notice them 99% of the time.

I feel it's something like 90% of the performance at 60% the price.

And I find that compelling enough that it seems likely, but not quite certain, that the 15-30 will be joining my 24-70 and 70-200 so I'll end up with a Tamron Trinity.
The only question I still need to resolve is am I willing to add another 1kg to my bag.

It sounds absurd, but I'm wondering if it will be worth the extra couple of hundred dollars to get the lighter 16-35 ƒ/4 nikkor and save some weight.

If filters are a concern I'd image you could use a matte box.
Take some of the $1000+ you've saved on the Nikkor + some of the hundreds you'd pay for the 14-24 specific system and buy a matte box that you can use on most any lens and likely get better light control - and probably still come out in front in terms of cost and filter capability.
Seems to work for Joey L.

In reply to:

Photoexposition: So, this is how Nikon plans to fight the 38,1% drop in DSLR sales since 2012 ?
Not to mention D7100 owners who will sadly face the value-drop of their camera on the second hand market. Excellent way to upset their customers, way to go.
When men can't change things, they change the name. D7100->D7200.
NFC ? Well, that's marketing BS that applies to compact cameras or smartphones, not a serious digital SLR camera. The years when Nikon was a pioneer and a real innovater have vanished (Nikon F, F4, D300, D700)
You wanted a tilt-screen ? Doesn't take a rocket-scientist to forecast a D7300 in 2 years with this improvement. We are passionate photographers, not milk cows.

@moinarcs - true that.

Some of the incremental improvements that Oly and Sony made are incremental, but they are big increments.
IBIS and the A7 (especially the S) being two that leap to mind.

In reply to:

Der Steppenwolf: So Nikon, for EVERY little improvement you have to buy new camera. Memory and processor in D7100 could have handled same buffer if not more but no. First they sell hat one, then they add tiny bit more memory and the game goes on. And memory IS DIRT CHEAP and has been for MANY YEARS now.And before flameing starts, I happen to know for a fact that this is true since I am one of the contributors to Nikon hacker community (google it), where we actually are dissasembling these cameras and their software to improve upon lowly features Nikon is putting there to begin with.
No shame what so ever in that company.

I'd hold my judgement on the buffer at the moment.
The press release says:

"With an extended buffer capacity, the number of shots recordable during continuous shooting is increased to a magnificent 100 shots in large image size, JPEG fine-format, 18 shots in RAW, 14-bit lossless compressed, and 27 shots in RAW, 12-bit lossless compressed. Furthermore, unlimited number of images can be captured continuously, as long as battery and memory card capacity permit, when using the CH or CL release mode with a shutter speed slower than 4 seconds. "

On the D750 with a fast card you can get about 3 fps continuous until it hits a 200 shot limit.
Apparently the D7200 does not suffer from the 200 shot limitation, and the press release mentions CH as well as CL.

A large buffer is not overly important if the camera has the write speed to clear the buffer as fast as it fills.
Then presumably the buffer is only used a temp storage for the image processing.

In reply to:

bogdescu: Might it have dawned on them that merely postponing a decision (where to focus and what f-stop to choose) is not actually something desirable?

@Henrik - A wider aperture would allow you to gather more light. If you could then refocus that light at will you could use less cameras to cover more area with less artificial light.
3m-~ is probably not going to be an aperture which lends itself to to low light.

Mike Sandman: It's very refreshing to read so many un-hedged, direct statements from a camera company executive. Thanks, dPreview, for asking the questions, and thanks Fuji, for answering them forthrightly. Mr. Iida even acknowledged Samsung. This kind of thinking is responsible for Fuji's successful transition from film to digital vs. Kodak's failure.

It would be very nice (and quite a surprise) to see an equally frank set of answers from Nikon or Canon about how their cameras stack up against the competitors.

@Rishi - next time you speak to a Nikon exec who wants to get input from an enthusiast/amateur photographer, please feel free to refer him to me. I assume you can access my contact details from my profile.

As an alternative, how about a reader's Q&A with Nikon executive?
And even a Canon exec, for those that way inclined (not that there I anything wrong with that).

Indeed. I wish Nikon were capable or roadmaps, unambiguous statements and even *gasp* talking to customers.
