On Calm Reflections in the Reflections in Calm Waters challenge (4 comments in total)

Excellent shot and great winner.

So my little summary is that these results suggest that at this s. speed VR doesn’t reduce the shake but introduces it.

This is the same result as your test done on tripod is showing (http://www.dpreview.com/previews/nikon-d810/10). Although unlike here you didn’t pick up on the differences for VR on/off w/EFC there.

Maybe I wouldn’t expect the VR to behave the same or very similar on tripod (collar mount and camera mounted) compared to when hand-held. I can imagine a whole range of specific changes reflected into the VR’s work and the results these two different support methods are likely to introduce. But it apparently is the case and your results support this idea strongly which is what matters.

The test with the lens on tripod is also useful as it is showing shutter induced shake and its cancelation when EFC is used (at the typical s.speeds @200mm) including VR on which again determines the shutter induced vibration/shift as the culprit.

My 70-200/4 VR on D600 is not affected by the smear caused by out of sync VR action seen with Nikkor 300/4 VR at the particular s. speed and cameras and which appears to be a very distinct issue.

However I follow carefully your findings with regard to Optical Stabilisation and its deteriorating effects at critical s. speeds as these prove to be just those useful s. speeds the VR/IS function is used for. This is brilliant work you are doing for us. I absolutely support the wider implementation of the EFC. And its wide use in all Nikon DSLRs. In fact, I think these are necessary steps and that Nikon, after the start of certain implementation of EFC in D810, will continue this direction.

On Nikon 1 J5: What you need to know article (493 comments in total)
In reply to:

HSway: With this camera the J series makes sense for the first time to me. But the ambition of J 5 design in N1 concept, although likeable, is very bold, so bold that it borders on naive. But this naivety or boldness makes sense from Nikon. And what makes sense can succeed somewhat. But mainly it makes some sense and it even seems to have got a little seed of mission in it. When something makes sense it keeps its dignity.

How about - first N 1 camera I like as a camera and as a product (using LCD for shooting). But in this segment I am not sure the typical buyer will appreciate the J5 enough for it to become very profitable (something to do with the concept of interchangeable-lens camera in this segment). But this worries me less than Nikon making bad cameras.

HSway: The Tamron might have less complex field curvature. It has better CA control, the scene tests this nicely. Differences here and there aside, the Tamron is equal player and gets you lens even bulkier than not exactly small Nikkor and narrower angle for a much better price. And gives you VC which may be that decisive feature for some. In other words Tamron again comes with an excellent option.

Yes, thanks. I am referring to axial CA as the more or definitely just as useful to get some comparative tools for. Surely these are more difficult to make and present. For lenses from f2.8 in particular but not only. Slower lenses like f4 can be quite terrible in this regard.
There are plenty of those measuring lateral CA.

HSway: Samples tell us 24 Art bokeh can be very jittery. I don’t say it lightly, I am not any of the bokeh fanatics or a Sigma basher and I am very happy with 50 Art and 60 Art in this particular respect. The point is that while this is absolutely OK with some, say, (14-) 24/4 lens the purpose of f1.4 lens fills also different roles where this is a consideration. I wish they take it into account with such fast lenses including UWAs and avoid rendition that really can be distracting and limiting for certain uses. (As distanced from the character; most people will agree on the difference - my Touit 32 can have unpleasant jittery bokeh @f1.8, it changes to character I love @f2.2, I could go on).
No it is not a disaster but it makes the potential of the lens less versatile.

Not that the standards are not high but thank you for the most interesting article.

OK guys, we come from various brands, you certainly have a point. Nikon has spoilt us maybe a bit more here (not always). 20/1.8G seems to have clearly struck a better balance. And 24/1.4G simply is a different lens - which does translate to having options as a good thing. Btw, and despite the first samples, it’s still early days.

I agree, absolutely. I haven't actually ever seen nearly this much CA from my lens on usual conditions. But I don’t shoot comparison tests for it often either:) Still, starting from LR 4, I think, this would take just the default profile to clean it.
I think that having high brightness/contrast induced axial CA quantified using a standard test would be (more) useful. I saw somewhere you or Barney referring to this as well.

Karl Summers: Aside from sharpness, how do you account for the difference in hue/luminance values in the blue trim around the window?

Yeah, that’s the one.

No Nikkor is known for holding more detail in the highlights. You will appreciate it if you process raws. I sold a lens for sterile highlights before (Tokina 100).

Have a closer look at these samples. I will link the discussion where we were debating the 24 Art. It's from Dpreview’s set.

I think each (UWA) design faces number of challenges. At this point I’d focus on breaking FL (AOV) numbers last. Much greater achievement, though less spectacular, is obtaining top parameters at the start/end of the range and from the wide open. There is number of challenges just for the resolution characteristics. Such as properties at the frame's periphery or the field curvature. They will want to keep the distortions in check and if they get bored there is the flare resistance or filter accommodating steps. 14-24/4 is then the best possible specification for the widest range of photographers. I would want to excel there. I am unsure Sigma will resist, though. They already have the 2d v. of 12-24 (f4.5-5.6)
The same for a 24-70/2. Just look carefully what numbers to break. You will never break them all and although the size/weight may not nearly be the priority it still remains a practical part of the product’s properties as does the general sense of a lens spec in practical terms.

Looks like 100-400 L IS my guess as well.
And the rumours about the 7d ll are culminating so there may be more good news for Canon in the coming weeks.
