What is creating this huge gust of water? And what kind of dam is this?

Marty4650: It looks like Sony is getting serious about FE.

Smart move, on their part. I hope Canon and Nikon are paying attention.

55 mm is also a decent portrait focal length for APS-C.

On Opinion: The myth of the upgrade path article (1290 comments in total)
In reply to:

Papi61: This is what I don't understand; why do you *HAVE TO* sell all your DX lenses when you buy a full-frame camera? This is what manufacturers would want us to do, but it's not a rational choice, especially now that lenses aren't selling on EBay as well as they did a decade ago. You'd be taking a huge loss, and for what? What's wrong with using a DX body *AND* and a FF one? A DX body is certainly more useful when you shoot with a long tele (or tele zoom), while your FF camera has the upper hand in low light. In other words, best of both worlds.

There is nothing wrong with having two systems that serve different purposes but that is not was this article is about. The article specifically talks a about using DX lenses on a FF body.

Papi61: Did we really need another iteration of the 55-200 kit lens? Looks like the thread size is the same (52mm), while the body is possibly a tad more compact. Most likely, the AF motor is the same (i.e. nothing to write home about.) I seriously doubt there's a way to squeeze any better performance out of this design. I guess they just wanted it to be smaller.

BTW, have you noticed that some people clicked on the "I had it" button? How's that possible? These lenses haven't even been released...

It is 25 mm shorter than Sony 55-210 mm f/4.5-6.3 E-mount lens. Since the flange difference is 28.5 mm, Sony E-mount camera with the lens mounted is only 3.5 mm less deep than a Nikon F-mount camera with this lens. And for taking up space in your bag, it clearly beats the Sony lens.

Joseph: No AF-S 24mm f1.8 yet. The 300mm does sound interesting though. Will wait for review(s) to come out first.

Its zoom range is so short, you could almost call it a prime.

On Hands-on with Nikon's new D5500 article (264 comments in total)
In reply to:

noirdesir: Multiple sources have reported over the years that Nikon uses non-Sony 24 APS-C sensor, from both their own sensor group as well as Toshiba. I have repeatedly heard that the D3300 sensor is a Nikon sensor and the D7100 a Toshiba sensor. Thom Hogan recently mentioned that the D5300 sensor is also from Toshiba. When the D7100 came out, it was remarked upon that it a tiny bit more banding than the D7000 (which had a Sony EXMOR sensor), suggesting that Sony still had a small edge in that regard.

The only other brand using a 24 MP APS-C sensor (besides Sony and Nikon) is Pentax. As Thom Hogan also mentioned that Sony hasn't offered its 24 MP APS-C sensor to other companies (or they did not want it, the NEX-7 sensor appeared to be much more picky in regard to the angle of incidence than previous Sony 16 MP sensors), it might also have a Toshiba or other sensor.

Ah ok, the lower end models (D3x00, D5x00) are a bit of a blur for me, in particular when they keep the same number of pixels.

In reply to:

jtan163: Nikon Canada https://www.youtube.com/watch?v=np37mHApfxU "a lot of those features it shares with the d5300"

I.e. really nothing much new here.
Touchscreen, super small size, eye sensor.
The eye sensor would be extra important if you were going to use an EVF.
I'd guess with an EVF camera the video can go either to the EVF or the LCD.

My guess is there is an EVF coming to Nikon real soon, and perhaps it was intended for this model but something didn't work out, or they are testing their code/logic/usability on this model where they still have an OVF, and it won't matter if the sensor behaves slowly.
Taken together with this fact that they say it's the smallest Nikon DLSR, I think mirrorless or at least an EVF driven Nikon consumer model is gonna be maybe the next model.
Also be interesting to see if the D3300 stays in the range.

I wonder if they'll fully exploit the interface options touch gives them in the next model. I dont think they have in the 5500 yet.
Glad Nikon is responding.

Eye sensor is also import if you have touch screen ...

Valentinian: Nikon 300mm/f4 ... shorter, lighter.......available next month for $ 2,000.
When will OLYMPUS release their 300mm/f4 ?????

The point to make is that a 300 mm f/4 lens for m43 and one for APS-C or FF don't have to be much different from a design standpoint (though they serve different purposes). Yes, the m43 version will focus more on centre sharpness and the APS-C/FF version more on sharpness over a wider field but longer tele lenses image circles tend to have noticeably larger image circles than necessary for the sensor format they are designed for.

On High-end full frame roundup (2014) article (574 comments in total)
In reply to:

StephenL: When will people realise there is no such thing as full frame? m4/3 is full frame to an Olympus user. Yet to a Pentax 645 owner, a Canon 5D sensor is tiny.

What is now referred to as 'FF' has the largest lens catalogue and had the largest lens catalogue for the last 50 years probably. And largest lens catalogue usually coincides with largest market share in the ILC market.
APS-C created an exception to that rule by creating a hybrid system using a flange distance and lens mount from a 24x36 mm system with a smaller sensor meaning people were able to use lenses designed for larger sensors very easily.

On High-end full frame roundup (2014) article (574 comments in total)
In reply to:

lacikuss: When you offer purchasing advise, like in this article, I'd recommend to narrow your comparable cameras based on customer segments and not on sensor size, which is pointless.

If I'm a video enthusiast, then I can't agree with your D750 top recommendation
If I'm a landscape enthusiast then I can't agree with your D750 top choice
If I'm a sports & wildlife shooter, then I can't agree with your D750 top choice
If I like light camera for travel, then I can't agree with your D750 recommendation
If I have a limited budget, then I can't agree with your D750 recommendation
etc.

High-end Camera is an obscure and very subjective matter.

Please learn some marketing fundamentals and start focusing on your customers preferences rather than the obscure technology that manufactures use to trigger desired features that most of the time true photographers hardly ever need.

If you offer enough categories, eventually every camera will will in at least one. How meaningful that is, is another question (the European awards for 'Best xxx of the year' follow that pattern).

And a lot of people aren't wedded to one category only, they shoot a wide range of subjects and thus a camera which is pretty decent in all categories is likely the best choice for the majority of photographers.

On Not dead yet: Sony announces three A-mount lenses article (123 comments in total)
In reply to:

Cheng Bao: "Based on CIPA standards. Compensates for angular shake (pitch and yaw). Measured using a Sonnar T* FE 55mm F1.8 ZA lens, with long exposure noise reduction off."

Wondering what the long exposure noise reduction to do with IBIS cipa rating.

Noise reduction can affect acuity, the impact of shake might be measured by measuring acuity.

On Not dead yet: Sony announces three A-mount lenses article (123 comments in total)
In reply to:

VirtualMirage: DPR, I feel that was a poor choice of words to say that the A-mount is "Not Dead Yet". It labels the brand with a negative stigma, one I don't think is warranted. Your headline implies that A-mount is dying or will be dead instead of reassuring that A-mount is alive and the focus on the mount is on fewer models that is focusing on a higher end clientele.

As we have seen so far, their product release cycles have not been longer. The release between the A77 and A77II is far shorter than it was from the A700 to A77. We could assume it will be the same with the A99's successor too. When there are fewer products to release, there will naturally be fewer announcements.

Now it would be nice to see more lens or flash announcements. This latest announcement is a good sign.

VirtualVirage:
You have very much confirmed my impression of a sad state of affairs.

In reply to:

mpgxsvcd: You guys do realize that the more controversy there is in these reviews the more clicks Dpreview gets, right? They have no incentive to put out an article that everyone says “Yup I agree” and then goes about their merry way.

They have been posting articles lately that attract attention because they are controversial and we take the bait. Personally I like it this way. I like the controversy. Others may not though.

Do you realise that your comment says more about you, than about DPreview?

If news organisation aren't allowed to make puns in their headlines anymore, then we've arrived at a very sad state of affairs.

Beckler8: Like all the haters here, I too think this is pretty stupid. It's a luxury image camera. But then admit that Rolls Royce and Rolex are ridiculous as well. At least this camera is a rebadge of a great model, whereas those two examples are badges of nothing.

Mark,
the car manufacturer Rolls Royce (now a subdivision of BMW) has long parted ways (41 years ago) with the jet engine manufacturer bearing the same name. Besides the name and maybe a logo nothing much still connects these two companies.

Rolls Royce engines are based on BMW engines. The Bentley Continental GT is based on the Volkswagen Phaeton platform.

FocusBogus: This Alpha series has a problem: A7, a7, α7 or Alpha 7?

My suggestion is that it should be named to "Alpha", like Cyber Shot. No more hassle with α.

Simple, it is called the Alpha A7.

I never said they were the same, just that they use the same technology (PD AF, one-shot HDR).
