nir-vana: Equivalent apertures are slower than what you can buy for FF cameras. So what's the benefits of this so called "medium format"
63/2.8 equals to FF50/2.2
For the A7RII I can choose f/1.4 and even f/0.95 lenses.

How can a lens have too MUCH pop?

arbux: Small sensor, dark lenses. Medium format in name only. Any Ff camera with glass F2.0 or brighter captures more light and is cheaper + has much more functionality.

Most reasonably priced lenses are pretty soft at f/1.4 and 1.8, so the "light gathering" isn't the only criteria.
Might we not predict that the combination of a larger sensor and Fuji's magnificently sharp lenses might give you a better looking image than a 6D and a $100 50mm 1.8 shot wide open?

phoenix15: Pentax will reduce price 645z by 1500 USD, and they will introduce "true" medium format with 100 Mp sensor. Now the real problem for Pentax is providing the lenses. Two thump up for Fuji with "quite affordable" GFX lenses. Pentax really need to respond quickly.

Nevertheless, I believe this GFX will trouble more to the Canikon with the expensive FF DSLR. I wonder if GFX can be used for action photography with their new AF ?

"Reverse crop factor"!!! Thank you for coining a new term! This is even sexier than "total light" or "equivalent aperture".
Good job.

rfsIII: It's happening again, at least for me this gallery looks all just a little soft. Are we sure there's not some percent of Gaussian blur being added by the CMS software? Or something?

They're fantastic images, by the way. Snow turns out to be a great test for how a lens resolves fine edges.
But as usual, I didn't explain myself quite right. Why, for instance, does the Canon 18-150mm STM gallery look so delicious and crispy in comparison to this one? It seems like some galleries are sharp and others are soft with no rhyme nor reason.
Or could it be that this lens is tuned to give photographers more leeway when sharpening. I've found that with some lenses, the more you sharpen the better the images look, while other lenses quickly get hashy and harsh when the sliders are pushed too hard.
It's hard to believe Canon consciously set out to make a mediocre version of such a popular focal length....

Actually, the first accessory a newish photographer needs to buy is a 36-inch 5-in-1 reflector. Lenses can't fix bad lighting, but a reflector can make a marginal photograph into a masterpiece.

nerd2: Image supersampling is real and a very active field of machine learning. (It happens right now in your brain!) I am not sure the saved bandwidth is worth the computation cost on the device though.

You mean your brain, right?

In reply to:

skanter: Like much on this "gear forum", the article (while pretty informative for beginners) promotes the idea that buying a DSLR is just an intro to a lifetime of "buying" more lenses - not to learning about photography. I would recommend beginners stay with their kit lenses for a couple of years and learn the basics of photography with it, before more buying and buying more gear. We constantly see posts saying "what lens should I get next?" Answers abound, with little thought about the poster's level of skill and experience.

Preach, brother. One of my favorite lenses is still my $250 Nikon 55-300, you just have to know at which focal lengths it is at its best, I treat it like a 70-200 and it's amazing.

tinternaut: I'd say telephoto, but one of those needs to come with some education about what a telephoto is for (i.e. possibilities for creatively playing with perspective, and a reminder that the best way to get closer or further from a subject is often something most of us are equipped with).

Yes! It's all about knowing what the tools do and the making a conscious decision about why you're doing it. A lot of people don't understand what they're doing when the choose a certain lens. They might unconsciously know, but it's always better to have a mental checklist to go through.

There's no such thing as zooming with your feet. But the explanation usually given for changing focal lengths results in many awful pictures because no one tells you what you're really doing. What you're doing is changing your emphasis.
Changing focal lengths changes the ratio of background to subject. It's the difference between storytelling and spotlighting.
The longer focal lengths show you less background and more subject, thus spotlighting the main element of your picture. That's why they're used for portraits, sports, and wildlife. Usually in those pictures you want to just put your viewer's attention on one thing.

Using a wider, storytelling, focal length shows your viewers more of the background while making your subject look smaller in relation to the rest of the picture. That's why they're used for landscapes and environmental portraits. You are showing context; what the main subject in the context of its surroundings.

You're right. I just get irked when I see a staff so unbalanced...the beard to no-beard ratio is out of control.

Ian Chapman: For those who have experience with GH4...could you comment on what ND filters you use when making videos? Variable or fixed? Which are best? Which brand? Also, how do you zoom with this type of ILC camera?

I use Tiffens which are good enough for the movie industry, so they're good enough for me and they're reasonably priced so I can afford a range. Variable NDs are two polarizers stuck together which can do weird things to the appearance of skin.
But the rat in the ND closet is IR pollution. Some cameras are very sensitive to this and some aren't. We won't know about this new camera till it's out in the wild but you can read about IR pollution here:

There is no more dangerous weapon than the truth.
In a time when we are drowning in fake news, this exhibit is a reminder that people of good intention can use the immense power of photography to shine a light on the evil in our society.
Bravo to the creators of this exhibit which is a callback to the motto inscribed on Woody Guthrie's guitar: "This machine kills fascists."

Kenny08: Sharpness also depends on the camera body that is being used? The sample shots were done on a Canon 5D Mark IV, so it'll be nice to see other shots taken on other bodies...Ie. 7D MKII, 80D, 70D, etc....

Pas de tout; mirror slap and shutter vibration are definitely detail killers. And here's something I've learned shooting video—a fact that the stills world hasn't yet figured out—lens and sensor interaction is a huge determinant of image quality. Certain sensors work better with certain lenses.
And there's the signal processing chain to take into account. Even when you shoot what you think is raw, there's still quite a bit of computation going on inside the camera that we'll never know about.
Bottom line: Kenny has raised an important issue, don't shut him down.

Way beyond my coordination level. I was always picked last in sports at school.....I can tilt, or I can zoom, but if I tried to do them at the same time, I'd definitely fall off the dolly.
As far as power zooms go, look at Sony; they do, like, a 28-135 powered zoom for their mirrorless cameras.

SmilerGrogan: Why is it so hard for corporations to understand that if you don't have a model release, you can't use the photo. Period.
We've tried to make easy for them. There's a whole section in the IPTC Extension metadata specifically for models including their age and the status of the model release. All they have to do is look.
Are they ignorant or evil? Either way, something has to change.

People who work in the field all know, or should know, that you don't do anything without a paper copy of a signed model release in your hand. And just because a photographer sends in a photo, that doesn't mean there's a release. The two events are not related. Especially in advertising.
And more importantly, how do you know what rights the subject has sold. Is it just one state? The whole US? North America? Or worldwide? And for how long? A year? Five years? There are a lot of fine points.
And the amount is meaningless. That's just to get Chipotle's attention.

You're right, I'm over dramatizing. But really, I'm angry at all American media including that other Bezos-owned property for being so obsequious to both Republicans and Democrats. The (predictible) result is that we will soon have a Russian puppet in our White House. If the election had gone the other way America would instead be run for the sole benefit of Wall Street slimeballs.
We see the same kind of editorial failure here; instead of speaking truth to power and demanding real answers to real questions, they let the corporat oligarchs control the message.
The result in both cases is the same—we the people are stripped of our dignity and made a mockery before the eyes of the world.
Bottom line: Need to stay off internet till Trump administration is over.

Nikon is annoying because they never give we customers straight answers about anything so why should they reap the benefit of free publicity. In the trade it's called "earned media" but they haven't earned anything in a long, long time.
Plus that Nikon rep looks like a character from a black and white British gangster film. I'm afraid of him and I'm not even in Nevada.
