Sdaniella: let's hope 7DMkII's new sensor has improved uncompressed RAW DR 16-17 EV by at least +2EV over the old 7D/5DMkIII RAW DR 14-15 EV sensors

and extended dual iso (dual gain) sensor architecture to read all pixel lines with two (or more) iso/gain amplification, not just one per alternating pixel (grbg doublet) lines, OFFER IT OPENLY or at least automatically (not hide it), so one need not rely on ML hack to extract (divert) the two potentially SELECTABLE different ISO image data from the sensor processed to the memory card ...

whew

if you got what I'm getting at
that puts pressure on Canon to deliver MULTI-ISO (multi-gain) capture (customizable handheld fast capture HDR stills and Cine video) sooner, not later

reminder: 4k H.265 ... Samsung APSC NX1 (digital 35mm 4k Cine) is here US$1500 ...

@Sdaniella

Yes I've used and tested 5D mk II & III vs. Nikon D800 in this regard as dynamic range is important for my work in high contrast situations. The shadow noise quality of 5D mkIII is bad. The dynamic range is simply nowhere as good as with Nikon or Sony. And this is a wellknown fact among pro photographers.

LOL Where did you get this figure of 14-15 EV dynamic range for 5D mkIII?

Its DR is mere 10.97 EV @ ISO 100 according to DxOMark screen mode (1:1 pixels) compared to D810's 13.67 EV @ ISO 64.

Canon sensors are NOT known for good dynamic range and shadow noise performance. D810 in comparison has the smoothest shadows (at ISO 64) I've seen so far in a DSLR.

DarkShift: Canon seems to be stuck too much with their old design of controls and interface. Not much improvements in this regard.

The thumbwheel position is not very good for controlling aperture or shutterspeed. It moves too easily by accident if not locked. Not good position for left eye dominant shooter either. Very disturbing.

I don't quite understand why they can't add control wheel to upper right of their bodies like every other manufacturer.

May be so, but after using Nikon D800 & D810 interface for sometime, the Canon's "time proven" user interface feels not so good to me anymore.

Using gear from different manufacturers is sometimes beneficial. One will quickly learn that something that you've used to do a lot of times may not have been the easiest way at all.

qwertyasdf: This might be the first and last time that I say this to a M43 lens:

It's priced reasonably.
Given it's longer range than 70-200 FF lens, it is way way more versatile, and I have confidence in the IQ of a Oly HG lens. Oh....also, the 0.21x magnification, taking into account of the crop factor of M43 sensor, is class-leading.

@RStyga

You don't seem to have clue. It is a true f2.8 lens, DOF has nothing to do with that.

@Oleg

Actually ISO control can be set to movie record button with D800 if needed.

For me there's usually no need to adjust constantly the other settings you mention while using OVF. So their position if very fine for me.

For adjusting aperture or shutter speed it's often not required to cycle through all values :D

And the Canon lock can't be operated on the fly. Fe. Nikon D810 works much better in this regard as shutterspeed and aperture can be locked separately. And it has much better user interface overall giving this 'designed for photographer' feeling ;)

The big question for me is if the dynamic range and shadow noise are improved with the new sensor in 7D II.

If not, it might tell something about sensor performance of the rumoured high resolution Canon FF camera. Sony is rumoured to release 46-50 MP FF sensor later, so Canon will face very tough competition.

Yes, I know but RStyga claimed that the Zuiko 150/2.8 is not a f/2.8 lens at all.

@RStyga

Please go read some photo science before posting here. This Zuiko definitely is F2.8 lens by definition which means its focal length divided by diameter of the maximum aperture is indeed 2.8.

On Zeiss introduces 'no distortion' Otus 1.4/85mm article (336 comments in total)
In reply to:

Mssimo: DXOMark has the review out already.

http://www.dxomark.com/Reviews/Zeiss-Otus-85mm-f1.4-Apo-Planar-T-Canon-ZE-and-Nikon-ZF.2-mount-lens-reviews-World-s-best-performing-85mm-portrait-lens

Nice information, but I would not propably call it the best performing portrait lens. Without fast autofocus I wouldn't use it for general portraiture but for anything else where AF is not necessary and subjects don't move too much. For portraiture it is not necessary to have the best absolute sharpness. More important is to have lens focused where it should be.

If one compares the results to Nikkor AF-S 85 f/1.8G on D800, it is surprising that the Nikkor actually has less distortion (0.1% vs 0.2%) and its T-stop is closer to the manufacturer rating than with Otus. Where Nikkor looses is wide open performance and CA & LoCA, but for portraiture this is usually not a big issue for me.

In reply to:

erotavlas: we all know everyone who uses this lens will still end up tweaking their photo's to death in Lightroom and Photoshop making whatever benefits this lens offers with respect to colour, clarity, sharpness, contrast etc kind of pointless.

I think 99% of clients don't even now what LoCA is.

The greatest artistic potential is and should be behind the viewfinder. Equipment has not much to do with the art anyway. Equipment image quality != art.

That said, this Otus should be great lens for certain situations but not so practical for general use.

In reply to:

Wedding photographer: I believe that the new perfect portrait lens should have:
1) beautiful pattern bokeh (Yes);
2) accurate and fast autofocus (No);

In my opinion modern lenses have acceptable sharpness (considering possibility of their mediocre autofocus systems).

I think, other parameters such as “flawless sharpness” and especially “No distortion“ should be placed on fourth or fifth place.

However Marketers of Zeiss have other point of view. They look based on synthetic tests of manual sharpness - far from real life.

Separate lenses of course :) One with ultrasonic AF for portrait use and one MF lens with tilt and shift for different cases.

Photoman: Wait till Sigma release their 85/1.4 lens. 1/4 price and better quality, like their 50/1.4 ART lens.

Sigma has much lower price compared to Otus that I wouldn't be too concerned what happens after ten years of use (if professional). It can obviously be used as manual focus lens too...

I would certainly be more interested if Zeiss would introduce 85mm tilt shift lens with shorter min focus distance. Obviously with even higher price tag :)

For a portrait lens to be used for about zillion frames, the lack of autofocus is a turn off.

DuxX: Wide aperture portrait lens without AF at 4.000+ $/€ price... pffff. Brainless! Really wish to see comparison between this lens and 85 1.4G and what buyers pay with 3.000+ $/€ extra!?

@Jones R

I'd say most working photographers do fine without the Leica Noctilux or Zeiss Otus. For great results, subtle differences of photo gear area not what counts but rather the artistic skills of the photographer.

@Jones R

Which junk brand are you talking about?

There is several extensive tests in the web comparing the Otus 55mm and the Sigma 50mm/1.4 Art. The differences in IQ are not too big especially regarding sharpness @ f1.4 and the Sigma has great advantage by having autofocus.

@Henrik

IMHO Choice of background is more important for great bokeh than subtle differences between different lenses with same focal length and aperture.

For comparing lens bokeh, it's essential to shoot the same scene. Then you may find, that the differences are in reality quite small.

Too much LoCa may be disturbing sometimes with subjects like closeup products, but usually not something to worry too much about.

Fine lens no doubt, but lack of AF makes this not so practical choice for portrait photography. The Nikkor AF-S 85mm/1.8G is propably the best reasonably valued lens for that at the moment and gives very nice results. No way I would use manual focus lens in every day use anymore.

More interesting to me is actually if Sigma will release Art series 85mm f1.4 lens at Photokina too.

On Niko announces service advisory for D810 'bright spots' article (379 comments in total)
In reply to:

Thys: What's up with Nikon lately? I don't understand their policy - flooding the market with FF models (the new one will the 8th new model in the same time Canon had 3) and one problem after another? ... and all this in an era of ever shrinking sales? Surely all the new model releases and continous QC problems must be hurting somewhere?

Better not to be too dramatic about this issue. The D810 produces images with much higher IQ than any of the current Canon models could. The sales have been very good AFAIK.

Both 5D models I've purchased were broken right from the start. Non functioning thumbwheel and big blob of stuck pixels visible on video. And there is this light leak problem with the 5D mk III.
