pgphoto_ca: Be carefull....it's not a f2.8-f4 with this sensor (2.7x crop)....it's f5.6-f8 or more.......the crop factor need also to be apply to the aperture :)

A real 400mm f4...is much bigger ! :)

let me try to explain.

With a 2.7x crop at 25mm, on the camera marking, the focal length in actual is only 25/2.7 = 9.26mm.

f2.8 is always f2.8
so if aperture is f2.8 then the visual opening that you will be when the camera is at 25mm* is 9.26/2.8 = 3.31mm wide.

on now, we talk about full frame.
at 25mm with a 3.31mm wide visual opening then aperture will be 25/3.31 = 7.55 so on full frame with the same visual opening on the lens it will be f7.55.

Still...

f2.8 is f2.8 regardless of sensor size. it just tell you the amount of light at any one point on the sensor is having an f2.8 eqv light intensity. But in real life, a full frame will have a bigger pixel so

pixel size X f2.8 light intensity => a full frame will do better then a small sensor.

Pixnat2: Very creative and beautiful, I enjoy it.

The comments about torturing insects are hilarious !
I guess those who made those comments never smashed a bug :-)

Hypocrisy at its paroxysm.

We do kill many insect and animals sometimes but it was never an evil intention. If you killed a frog that is poisonous, it may be still fine but if you killed a frog just for photography then it is evil.

forpetessake: Before people start cheering and celebrating, they need to understand that Sony (just like other manufacturers) mislead the ignorant public providing equivalent FLs and conveniently forgetting to convert the f-stops to FF as well. So they would advertise RX-10 lens as 24-200mm f/2.8 equivalent, while it's 24-200mm f/7.6 equivalent.
Same with these lens designs, they provide an equivalent FL and 'forget' to provide an equivalent f-stop.
If you look at the actual equivalent numbers, like the first design is 26-112mm f/5.1-9.0 you'll be a lot less jubilant. The lenses are quite dim, no faster than they were in the compact 35mm film cameras of yesteryear.

hi forpetessake,

They are correct about your comments. But you are correct about yourself.

Why everything these days look more and more like a melted bar soap?

By contrast, Fuji, Olympus - well done!

well said.... haha.... do you need to take into account of lens weight, flash weight etc to finally determine ergonomic...

Zeisschen: With the a6000 news just prior to this, it's hard to believe both product pictures are made in the same year 2014. Compared to the modern Sony design this camera just looks like a cheap plastic tool from the 90s.

to Zeisschen, 1 like for your post.

Mirrorless today is no lack of lens. There are so many adaptors to choose from. I think it is only correct to say that more than 90% of the lenses in the world will fit an mirrorless camera or E Mount Camera.

In reply to:

munro harrap: We have to wait and see how the theory works in practice. I use an R1 still, at base iso in RAW it is excellent, and have been waiting for this since then. But I am puzzled because if the 1" sensor allows a max of 5472x3648, and the sensor is square, how come there is no max resolution available (according to you) of 5472x5472? There should be, indeed there must be, because otherwise the sensor is not square at all!!!.

What exactly IS going on here? Have Sony stupidly chosen to limit resolution, in which case we can all wait until Nikon grab the sensor improve the image processing as they always do and market their own version complete with 5472x5472 and we can bin our Hasselblad film bodies for good!

More accurate information please!

I understand that you take raw but do you understand the difference when you take raw with base iso and max iso?

DVT80111: Live view AF is still useless for still picture until Canon add a EVF.
The screen is too small and my arm is not long enough.

evf is even smaller then the screen?

what has it to do with your arm?

bgbs: Do you shoot professionally? I do not bring a mirrorless to any of my client work, and they certainly don't expect me to. But I agree, mirrorless is my go to camera when I'm shooting around for pleasures sake.

what has shoot professionally to do anything with the camera?
U think small camera cannot be more expensive then a DSLR?
or small camera cannot produce a better photo then DSLR?

In reply to:

HawaiiVolcanoes: This article is meant to get attention..nothing more...sooo you've succeeded, this time. I believe that this article is short-sighted and irresponsible. You keep shooting with whatever you please..and I will continue to shoot with my 85 1.2L and 5DmkIII and amuse myself at the end of each day with a glass of rum, my images on my 27" iMac...and the ramblings of another so-called "photographer" that for some reason thinks that his opinion matters...all of these crummy little Pen Cameras and Mirror-less this and that cameras are meant to draw people away from Cellphones...Amen

Actually. what define a PRO is what photo they produce. U do not define a PRO just by having a expensive DSLR. A lot of PRO does not like small cameras but it is true that camera are getting smaller and better. It is really not about the camera. It is about the photographer.

If you insist on your thinking then is medium size is more PRO then full frame?

whtchocla7e: What is the point of this campaign? To get some likes on Facebook?

I need way more motivation than that to get away from the computer and actually do something. I doubt the Internet is the right medium to transmit this type of a message.

Just to share my experiences.

There is this charity event which ask for donation to buy chairs for a school who cannot afford new chairs. So I paid for a furniture company to deliver the 50 chairs to them. Something that shocked me is that the furniture company tells me that the organization ask for a refund and demanded to return the chairs and in turn refund the money to the CHARITY organization.

It really makes me mad.

@Impulses may just be correct for most of the campaigns.

On Canon EF-M 11-22mm f/4-5.6 IS STM Preview preview (80 comments in total)
In reply to:

Beat Traveller: What I don't get is why this lens is only compatible with the EOS M. What about the EOS100 they just released? Why would you go to all the trouble of designing "the world's smallest DSLR" and then develop compact lenses that can't be used with it?

The heaviest lens is much more heavier then the heaviest camera. So it is more important to reduce the weight and size of the lens then to reduce the weight and size of the camera.

Canon have the smallest DSLR but got no small lens that goes with it. So eventually why smallest body only?

In reply to:

Fatality: I wouldn't upgrade to 6D not even for $500. To me, the 6D is worth about $1000 MAX.. My 60D is more superior than this camera (which currently sells for $780), not only that it takes EF and EF-S lenses, but it even has a shutter speed of 8000.. pfff This is a major failure from Canon.

Actually there is no diff for 1/4000 and 1/8000. What shot needs 1/8000 and cannot do with 1/4000?

On Best Camera of 2012: And the Winner is... article (1412 comments in total)
In reply to:

Anastigmat: I have 2 words for the results of this poll: ballot stuffing.

if you think people vote more then once (with multiple accounts) for EM5 then what makes you think that people will not vote more than once for nikon & canon & sony? Respect the decision of others. If one day, others commented that your photo are lousy then your photos are lousy to THEM. As long as in your heart your camera is the best then your camera deserves YOU.

In reply to:

G L: I have a m43 camera and the EM5 is what I would like to have. So I voted for it.

Just one remark: If Nikon had not the D800 and the D600 in the competition they might have won.

But anyway, the EM5 is a camera of which many people think it is a very good compromise between capability, size and prize. It really is an achievement to bring all these features in such a small package. The EM5 deserves this win.

I am a sony supporter... When I see this EM5. I am shocked. So immediately I went to try this EM5. All I can say is that for that size and that price, it deserves to win.

In reply to:

VadymA: DPR, please change the title to "The Most Interesting Camera of 2012", because this is what this poll is really about. I don't have any of the listed cameras but I voted OM-D because to me it was rather a head turned in 2012 and I think it deserved its place fair and square. Is it the Best Camera out there? Probably not. But we are just DPR Readers, not the camera experts. This is Our poll, Our opinion, Our fun way to pick "The Camera of 2012". Those who believe otherwise and come here with angry comments only make fools of themselves.

The word Best is very subjective. Wild life shooter and a wedding photographer has different best in their heart. So whose is best?

Peter 111: Overall score A99: 84%
D800E: 84%
D800: 82%
5D3: 82%

"It stands out as the only full frame camera to offer in-body stabilization, an EVF and articulated rear screen." WYSIWYG EVF, throwing away the Hoodman now. Sold my D800 and got an A99, loving it :)

@jmmgarza
I believe the one who produce the perfect photo is the photographer and not the camera.

@Petka
you memtioned that EVF will always have too much lag for precisely timed shots. May I know how much lag are you talking about? Sony is for SONY users only

tedious is because D800 is perfect. Since D800 is perfect then the rest will never be good. The Best camera is always the one in your hand.

Spectro: if the translucent mirror flipped I would be interested.

Translucent mirror to flip where? It is a limitation in the old SLR design thats why the mirror need to flip. else it will be blocking the sensor. So if can dun flip then why you still want to flip?
