On article Yongnuo announces YN360 LED light wand (33 comments in total)
In reply to:

Marksphoto: Yong needs to make a transmitter for this light , it would be very usefull for mirrorless cameras so that the light turns on when the shutter is half pressed. That would be revolutionary .

Why only mirrorless? Just curious.

White balance looks a bit out.
Of all the audience's not to check your white balance for I can't think of many that that would be worse than the DPR crowd.

On the content itself - it's like wow I've been prejudiced all my life - I guess most others are too.

On the question of exploitation - how much benefit do the individuals or homeless ppl as a class get?

If you want to shed the exploitative label then tell us what the subjects get out of the series, either as individuals or as a class.

There's no information about the subject and their stories of how they got where they are on Aaron's project page or as far as I can see any links to anywhere else with that info, so it really doesn't seem to draw attention to the subjects and their stories.

So yes it *appears* exploitative. If Aaron wants to dispel that he needs to tell us why it is not, because primae facie it is exploitative. The benefit the subjects get is not (based on the project info) proportional on what Aaron gets.

John Barkley: On the D5 and D500, does anyone know if there is a "focus peaking" function on the LCD in video mode? Sorry if this is posted, I can't find it.

@Deliverator - I don't see the recording of zooming as a problem (once you know about it) - it can be used as a creative effect at times, but it has it's down side for live use as a focus aid.

In reply to:

Muskokaphotog: The new Nikons are unquestionably great cameras. Apart from "professionals", who uses anyone of these cameras enough to justify spending the extra $? The other issue is the lenses. I have been using cameras and lenses for over 40 years and I think lens quality has actually regressed at the professional end. Sure we have better AF, but most lenses now need serious computer rejigging to compensate for distortions and other aberrations. When will Nikon create a standard lens with the corner to corner sharpness and a distortion free horizon?

I think you are both remembering through rose coloured glasses.
I look at old photos now - not amateur photos, but photos from books or magazines etc, and see chromatic aberation, distortion, blurriness etc etc.

Not saying there might not have been some great lenses - and frankly I don't have the experience from then to know.

But looking at the majority of the images from back then, I'd say the majority of lenses were not as good.

@Deliverator - yes you can, but if you zoom in in LV when recording the recording will be that crop - at least that's the case when you're recording from the HDMI port on a D750.

alexne: I don't think Von Wong's has made a name for himself by making things look real. I think "Cool" is what he goes after.

@VonWong - please let me be the first to say (in this venue) well done, nice process and write up! :-)

Aroart: I find it rather amusing how many photographers think there so artistic and creative when most take snap shots with high end gear and mess around in photo shop a little ... Its funny how they say there telling a story when all there doing is documenting an event.. Von Wong is a true artistic photographer his images are worthy of fantasy art and graphic novel covers..

I find it amusing you have "art" in your handle and no URL or galleries, and apparently no idea of what art is.

Von Wong is creative and this work is artistic but the message about shark's is coarse and I don't think particulalry great as visual art (but who am I? No one right? YMMV).

The value is for a company that want's to produce an difficult to produce image they know they can go to VonWong and say, here's $200,000 please make us a photo like this and he will.

His value is as a determined problem solver with the judgement to be able to assess the possible from the currently not possible, and the engineering and people skills to then get it done safely.
That's where my admiration for Von Wong comes from.
Not sure if he is a commercial photographer in the traditional sense, but it you want companies to give you $100Ks that's what it takes.
Epic image engineer. His words. Technician? for sure.
Artist? - all photographers are.

xiao fei: So... 6 stops.. that's handheld at like 1/15th of a second right? 1/(1000 / (2^6))

@xiao fei - I should calrify my 1/15th second with IBIS on an EM5 Mk I have been with relatively short lenses - e.g. 17mm, 45mm.

However your head will explode even more when I tell you on a good day, when my hands are really steady or propped against a post etc I can get usable-decent shots over a second.

It really is amazing tech.

In reply to:

jtan163: @DPR staff any news on whether either of these have an AA filter?

I'd be surprised too on the D5 althought I wouldn't be totally surprised if if was only weak/one axis as alleged by some on the D750.
I'd love to know what the magic pixel size is where it's no longer necessary.

In reply to:

KrisAK: I'd read that the earlier D750 had zebras (for video). Is that not the case?

Seem strange that such a feature would be omitted in these newer cameras.

Zebras are in - read the brochure.
Features like this tend to be a feature of the Expeed generation so if they are entirely software features they stay in.

Stacey_K: But what about the "shutter shock"?

@Rishi You didn't mention the EFSC to assuage the Nervous Nelllies.
I know the D5 has one - do you know about the D500 yet?

Not sure if you've spent much time in the FX forum lately but shuttershock is the latest fear/ "Nikon fault".

In reply to:

Nukunukoo: According to Jared Polin, the touch screen cannot be used to select AF points. Any confirmation to which is which?

@DIgital Walnut - that's in LV - the D5 can do that too according to the brochure. It's different to what they mean when they say focus ppoint selection like the D5500. ON the 5500 part of the touchscreen is active to touch control without an image being displayed and you can use it like a touchpad in OVF mode, to select OVF AF points.

Hopefullly the live view touch to focus in the video will trip the shutter too, like the Oly EM series.

In reply to:

matander: As i see it yesterdays Nikon announcements were to battle Canon, they still dont have anything that to compete with Sony on video features. The d5 and d500 could very well contain the NX1 processor wich would be a first step for the nikon/samsung cooperation. The 3 min limit for 4k filming indicates that Nikon doesnt wanted to step into pro video with the d5 and d500.
From a marketing point it would have been suicide to introduced the d5'(xx)s together with a new pro mirrorless system.
In that perspective it is good that Samsung talked about friges yesterday, a mirrorless cooperation will be announcements by Nikon as that is the brand that will generate the sales, hopefully with an NX mount that support both FF and APS-C.
I'd guess that Nikon will tackle Sony at CP+ with new mirrorless offerings in cooperation with Samsung..?

I actually have an atomos samurai so I'm not speculating about how you record from HDMI out generally
.
You don't have to activate the camera's record function you just set the HDMI output to be clean, and turn on LV. You can trigger the recorder from the camera but you dont need to and when you shoot DSLR video.
If you do you get the camera's time limits.
And it's obviously a real disadvantage to do so with 4K in a D5/D500.
Unless the 3 minute limit is only for internal recording, which may be the case. Very keen to see the manuals when they come out.

jtan163: Oooh - the hardcore "pro build quality/pro body" snobs will have to have a cry - the D500 is not all metal.
Amateur body with an AF-ON button and "pro" button cluster instead of mode dial ... those guys are gonna really be confused.
D750/D5500 construction.

No it's not a problem - I'm just baiting certain "pro body" snobs who for years have been saying that such and such is not a pro body because it is not all metal or doesn't have a dedicated AF-ON button, or because it does have wireless or a tilty screen etc etc etc.

It's gonna make their ridiculous comments untenable.
Even the D5 has a non proffesional touch screen now....

The moving platform with sony isn't problem.
I use an EM5 for stills and leave it turned on it does not get hot.
The problem is 4K video on both brands.

Sony's 4k handicams which don't have IBIS have cooling vents and I think fans. Their first generation handicams had offboard 4k recording, same with the A7S MkI - no in camera 4k recording, but it could do 4K to an external recorder.
Pretty sure Canon engineers went on record and said they same thing about the 1st gen C300s - no 4k due to heat.

Its heat from computation that is the problem.

So if the model number is an indication of technology, then how does that fit with the D600, D750 and D810?

What an ill conceived naming system. I thought it was gonna fail in about 5 years, but its actually going to fail next iteration now.

In reply to:

Marc Ramirez: Need 4 times the light to expose the larger ff sensor, so f8 dof equivalence. Or crop a 300 f8 full frame sensor to m43 levels and see how the images compare.

@atomicfish - actually a lot of people do care about shallow DOF with long lenses. Much nicer separation.

My 300 2.8 is an awesome head shot lens.

Yes and 1/15th is very achievable on the EM5 MkI with it's IBIS so I am not surprised by this on newer bodies with additional in lens stabilisation.

In reply to:

callaesthetics: If i put a full frame 300 f4 lens with an adapter on the Olympus i get the same image and exposure correct? And it only uses a small image circle from the full frame lens, the Olympus is engineered so that it uses only a image circle made for m43 sensor, so why are the lens the same size? Shouldn't this lens be smaller?

@ callaesthetics
No.
It's still a 300mm lens and the aperture is a function of the focal length not the sensor size/required image circle at the back end.

To get the same angle of view as a 300mm on a 135 format lens you'd get a smaller lens.
I.e. the 40-150mm ƒ/2.8 which is equiv to 300mm angle of view on 135 format.

But angle of view this is a 600mm in 135 equiv.
