No this is different.
Tracking and zoom are diferent things and so is this. This however does seem to take a lot of work. Here they are pinning objects in the scene, allowing to move selective objects in and out. Like your video just with selcting the railing or the lights only.

Just wow,
His bigest argument is that the android has too many choices and options. Thus Apple is better, because you are limited and stuck with one option.
Sorry even that is garbage as there are other camera options on iphone.
If you truely care about photography, you learn how to take photos, the tool you use if irrelevant.
This post makes me feel that Apple has finnaly lost control and is grasping to get market share. I will not be surprised now if lots of movie stars and athletes start saying how good Apple is. To me its a sign of the end.

A true soul hunter camera. The S7, should be marked with a mode to find your hidden inner demon. Both sides lady are exposed in full colour.

I think this article is a little over the top on the issue of sand. I bring my Oltmpus E3 to the beach with both 14-54mm and 50-200mm sealed lenses. I even carefully switch lenses there and for true test hand it over to the kids to shoot with, currently 9 and 6. No issues since 2008!
Maybe because its Olympus or maybe the author is just a little over the top on the issue of sand.
Or maybe the E3 really was hurricane proof?

Roland Karlsson: Why call it stretch? Why invent new words for already known things?

It is either variable length, macro focusing or helicoid. All perfectly fine names. The word stretch do not add anything to humanity, other than just confusion. And maybe also Fotodiox'es marketing department get happy.

BTW - stretch hints that you pull it out and push it in, like some kind of LensBaby fun adapter, that you probably also can tilt a bit. Is this the message they want to communicate?

They don't want to use the correct terms, like macro helicoid, because if they did you would find 50 better cheaper products. They need news headline and a new name so they are all you see in a search.
I have yet to get a product from them that has worked. My nikon to canon g adapter would not fit and needed filing. My pentacon 6 adapters from them were 1mm too long and will not focus to infinity. Much cheaper Chinese products to replace have worked without fail.

vscd: I have a better plot. They all are taken with a Canon DSLR and the Dynamic Range is so low that they have die in darkness. The mainactor tries to push the shadows but they all coming back noisy and with banding.... what a horrortrip ;)

You forgot the banding with LED light. Oh wait thats Sony.
My bad.

dash2k8: I want that flash! So small yet so powerful, why hasn't any of the major brands made something like this yet? Canon, Nikon, Sony et al., are you guys seeing this!?

I dont think that flash comes from the camera. Rather the light emitted as your soul is being ripped out of your body.
Also why the images are so dark, the flash sync can't match the soul ripping speed.

Yep using excellent Nikon glass with adapters on the Canon cameras cause slow manual focus. Those Canon cameras are terrible. Time to switch to other brands.
Seriouly dpreview, this is junk. If Sony is slow with Sony glass than fine. But using a non intended lens with a third party adapter is ridiculous. People should be glad the option even exists.

SmilerGrogan: There is a much simple answer to this problem. Shoot the camera like your readers would—use the manufacturers autofocus system for the test scene. If the results are sharp; GOLD! If the images are soft; that's the way the cookie crumbles and better luck next time.
Retesting a camera isn't fair to you or the readers. It wastes your valuable time and gives readers a false sense of what the cameras are capable of. None of us have all day to focus one photo and neither do you.

@Rishi, I agree but to be honest you do leave cameras at default settings. Not kicking back over handed NR, or sharpening. So the is variables not addressed.
I do like the green curve red curve conformation. That should save time in future an you could see if other cameras are correct.

NZ Scott: An interesting explanation, DPreview, and good journalism to "come clean" about your processes and difficulties.

You mention that you use 85mm-equivalent lenses at f/5.6 equivalent and, as a Micro Four Thirds shooter, I'm curious about the one you use with M43 cameras.

Is it the Olympus MZ 45mm f/1.8, set at f/2.8?

If you look at a m43rds tested camera and click the little i in the bottom right you will see the details. The gx85 test was shot with the olympus 45mm set to f5.6.

What privacy issue?
So lets ban people with photographic memories.
Lets prevent people from interacting.
Lets lock everyone up so no one will see, remember or bare witness to anything.
How is having this any different? People whom argue privacy issues need to rethink leaving their house at all.

With a name like Nikon Miami, I guess he is not going to be using an Olympus or Panasonic camera. But that D4 setup with 800mm lens just looks like an ad for the Panasonic GH5 with the Olympus 300mm with Tc converter. The 6k photo mode and olympus lens combo would just be so light, cheaper, faster (to move around) and fun to use. However you would not nearly get as many stares from the old men in the golf carts.

This sounds like the Nikon bought up Samsung mirrorless rumour. We all know that was true.

Scott Eaton: As a macro shooter struggling with Canon sensors and their annoying low color accuracy and habit of 'color puddles' when it comes to saturated warm colors (red is the worst) I was expecting this camera to do better than grocery store print film. All I have to do is look at the test results to see the Foven has *worse* color response under high gamut conditions than my 60D. The Foveon captures more spatial detail, but at a far more limited brightness / gamut range, and that sucks. This camera proves that just like bayer we are reaching the limits of RGB capture and need to expand to a physical aquisition mode with 4 or preferably at least 5 filter windows. RGB is fine for low gamut scenes and remote space probes, but even colored thread on a spool proves it's inadequate for full pictorial use.

Actually Olympus cameras use 2 different green colors on the sensor. Thus why its best to use VNG4 in Rawtherapee as the Raw handler.
This is why people talk about the vivid olympus colors in the old four thirds forum.

obsolescence: I'm attracted to the Foveon cameras, but uncertain of their usefulness in professional practice. As stated, it’s not likely to be my “only” camera — that is definitely true. But will it be compatible with my existing system (and with another one that I plan to acquire)? I see that as a problem not just in terms of lenses but mainly the significantly different color-tonal rendition. If I’m shooting a series for a project, all the individual shots need to be fairly consistent. Other than the desirability of fine detail, I’m not sure the Foveon rendering would be an enhancement or a detriment, unless it were to be used singularly.

@obsolescence
I think I see. The answer is no. That is not why you would use a Sigma camera.
In video its convenient to have the output all match, so you can mix b cameras and still have smooth transition.
You should never mix diferent sensor tech if that is the goal.
Olympus uses 2 different green colours on sensor, and will not match a Nikon output. But will produce some vivid landscapes. Sigma cameras are great when you need extra details in blue, red or yellow. The Sd14 I have produces the best yellows. Also I find Sigma cameras to really ne Ir cameras with a block. If you want the best detail Ir images use a Sigma.
So you pick the tool for the output you need.
If you want the same output, easier to just buy the same camera make or even a set of similar models.

Lan: In other news, water wet!

Seriously, they're looking to cut costs, raise yields, and increase sales?! Is any business *not* trying to do that? That's pretty much Business 101!

Thats the old business model. The other one is have one looking really good product. Put just enough into it to look really exciting. Then get bought out for millions.

It depends on what your other system cameras are. If you dive into Sony with the E mount. Then you can use the exact same lenses on both cameras. Get a SA MC11 adapter and the art lenses and you would be set.
However, other systems this would not work.

Also the question is not why is the output different, but which output is best for the client?

Thank you Richard Butler,
But is this all?
I would like to know your feeling on the Evf? Does it hold color compared to the lcd and other cameras with evfs?
Does the evf struggle in really really low light? Can you see something in near darkness? I am hoping yes like Olymus evfs, so can be used for uv work.
Any plans on popping out the dust filter for a quick dive into other spectrums? These cameras are the best for that, and to me the best sales argument for any sigma camera.

If this is all, thank you for your time with the sigma. Good to see an other sigma review here.
