Preternatural Stuff: Amazing how the Fuji apologists burst out of the woodwork to try to defend their GFX. There is nothing "brave" about this article. Its just factual.

1. Sensor size - "The GFX 50S’ 44x33mm sensor has an effective 0.78x crop factor".

This is the smallest of all sensors you can consider a MF sensor, i.e. the smallest step up from a FF sensor. So the "MF effect/benefit" is marginal as opposed to a 6x6 or 6x7.

2. Why marginal gain? Sony no longer provides its latest/best sensors to competitors like Fuji. Sony said that Nikon will no longer get its best 35mm FF sensors too. Get used to it. But then whoever didn't see it coming is a dope!

3. The article stated the benefits of large sensors for those who don't already know, so It's very balanced. No denial/conspiracy theory. Fuji apologists - no need to flog a dead horse trying to justify why bigger-better etc. FF users already get it.

"facts" show that the best FF basically offers the same image quality as the GFX MF? "

So we agree the headline should be "Thinking of buying a GFX read this first".

How can this article not mention the resolution of the cameras with more than 50MP? Do we not suppose a h6d 100c might have a higher resolution?

They are facts. Facts that belong in a review of a camera

But this isn't a review of a camera is it. Its meant to be about digital MF. It cherry picks the best of FF and then compares it to subset of MF

It is in brief a silly article on DPReview. It would make sense in many places but not here. DPReview have consistently pedaled the message that more is better in every area including resolution. Print size has never ever been mentioned, unlike Imaging Resource which always comments on this. I have always felt that print size wasn't mentioned because resolution passed a point that it is so good that is irrelevant

But suddenly at this point 50MP is enough. Why 50MP not 24Mp or 200Mp it just feels arbitrary. Also we are extrapolating from first generation products. The current state of Medium format sensors lags behind the current 35mm sensors. But what of the future. There seems no place for medium format sensors to move forward.

There are some people who really need bill board size prints and its hard to imagine that, in the long run, medium format won't be the way to do it

Finally take a picture with a street light in it, its not low dynamic range is it

In reply to:

KrampusClaus: resolution is quite poor considering its somewhat competition, look at woodcut print left of center the upper left corner and background, it compared to the a6xxx, canon m3/m5, etc make it very low resolution, in the ultimate detail sense.

obviously it is the lens? or smearing processing?, how can we know ?

the results are the evidence !

I don't think anyone sets out to create a lens that doesn't have a flat field. But I think it is a common issue and an accepted compromise to keep the lens small.

I don't think dpreview can be expected to test cameras with a variety of lenses, I mean where do you stop.

But the testing of cameras with a great lenses stopped down does need to be better expleined by dpreview in conclusions. The Sony A6000 etc. are a case in point. They get raved about here but the lens selection is till an issue. One consumer telephoto that is poor and expensive. Ultra wide is expensive. There are so many more goo cheap options for Nikon and Canon

Mariano Pacifico: In comparison to Canon Powershot G7x Mark ii, I can see G7xMK2 is way much better at a cheaper price ...

You got to love dpreview. I'm glad you like you Canon but you can't really call that camera an alternative. It's not even got a view finder....

On article Flickr reveals its top 25 photos of 2016 (190 comments in total)
In reply to:

King Penguin: For gawds sake......you commenters really are a bunch of GOM (grumpy old men)......and many of you are probably not that old! Quite frankly, I'd be happy to have taken any of these images.

I know Flickr ain't perfect, but before I joined a few years ago the only people who viewed my pics were my family and my friends.......and often they weren't always appreciative about viewing my output. Now more people see my photographs on a daily basis than saw them in the whole decade before.......and when one of them is 'explored' (I've had 32 so far, the highest ranking one got to no.7), the feeling one gets as the views and 'likes' increases over a 24 hour period is very pleasurable.

I've also been contacted by people looking for images and now some of my pics grace album covers and books and have been featured in magazines, etc.......none of this would have happened had I not joined the Flickr community.

I believe my photography has improved immeasurably since joining as I see others peoples images, compositions, colours and locations and try them out for myself.

To me Flickr is a window into our beautiful, diverse, wonderful yet sometimes cruel world.......all all images are different yet all are familiar.

So come on guys, stop prattling on about how your mirrorless marvel is so light and some unimportant last year yet essential this year gizmo will helped you 'nail the shot' or getting annoyed 'cause your camera keeps overheating when taking endless 4K videos of your goldfish swimming around it's bowl and get out there shooting and sharing.........who knows, you may actually enjoy it!

Merry Xmas :)

Almost every grumpy person or pixel keeper on here has gone to spectacular lengths to make sure no trace of their photography is on line

Readers awards are about as silly as it gets. I suppose it helps the marketing team know how well they have sold the dream and it tells dpreview if people believed their reviews. But surely most people who vote will have no real knowledge of the products and how they compare

On article Ultimate OM-D: Olympus E-M1 Mark II Review (1361 comments in total)
In reply to:

showmeyourpics: Hi, I had an interesting and enjoyable discussion with "entoman" about the current role of camera technology in the photographic process. My 2c on this subject are as follows. Technology surely is a great enabler. In today's cameras though it has reached a point where any "serious" model you buy is going to be very competent and give you great IQ even with poster size prints (follow "Fun 4 all" links). I am not the only one I know who takes advantage of the launch of a new camera to buy the deeply discounted previous model. Also, you can keep the camera you have much longer and spend money on upgrading your lenses and improving your technique by, for example, attending reputable workshops. There is no perfect camera system and different sensor size ones should be judged independently. I am a fine art, part-time pro and what this review has shown me is that, while I drool on it, I don't "need" the E-M1II because my E-M5II is already capable of elegantly handling anything I throw at it.

Yep I agree. I bought my D70 and 18-70 for £350. launch price £1200

I then 7 years later it was getting flakey. So i bought a D90 mint be used for about £245

Spending bucket loads of cash is an option

On article Fast Five: Sony Cyber-shot RX100 V Review (420 comments in total)
In reply to:

Jersey Shore: A solid, fair review that Sony needs to read. You know what amazes me? How much Sony is still fleecing people for the original RX100. That camera should cost no more than $299 at this point.

I bought a rx100 and £250 and I thought it was a great buy. Thank you Sony for giving me that chance. Apple would never have left an old model remain at better than half price.

For me the only real benefit of the the 3 and 4 are the view finder, which I'm getting on fine without

The lens of the newer models is probably better but it isn't a slam dunk. I've taken loads of great shots at 100mm equivalent or cropped to upto 200mm equivalent. The newer lens would be worse for these shots. I've also really enjoyed the F1.8 at 28mm equivalent in social situations. The newer cameras can't do that they are something like f2.4 at 28mm equivalant

In reply to:

Hachu21: So 24fps burst is one of the main selling point of this new RX100.
Great.
But the french website "les numériques" is claiming a slightly different story :
To reach 24fps the camera double 1 image every 3 images taken.
this means that on 24ips, you have 16 real images taken and 8 that are doubled.
http://www.lesnumeriques.com/appareil-photo-numerique/sony-rx100-v-p35601/test.html

16fps is still an impressive score, but this marketing BS (if confirmed) is a bit irratating and useless.
Any details on this?

Surely you can't shoot 24 frames a second with a 1/24th of a second shutter speed. There must be time between frames digital or mechanical

In reply to:

User3723086768: I don't get it how DPreview can asses that the RX100 IV has better Build quality, Ergonomics & handling, and Connectivity than the RX100 V, if they are exactly the same. Perhaps Ergonomics & handling has something to do with shorter battery life, but apart from that, everything remains equal.

I don't think that you can read scores like that. They are scored in the market they are launched in.

On article Setting new standards: Nikon D5 Review (505 comments in total)
In reply to:

Joed700: I don't understand why the Nikon D5 would receive such a high rating from DP. Looking at the spec sheet from DXO Mark, the D5 is ranked number 8 compared to other Nikon, Sony and Canon bodies in ISO noise performance, way below D4s or Canon1Dx Mrk I. In terms of DR, the D5 is even below Canon 5Ds/r and way below the Canon 80D and most of the Nikon FF bodies. FPS - Nikon never caught up the Canon 1Dx... I'm not trying to be difficult here...I do shoot both Nikon and Canon.

Because its an action camera. It isn't an accident that the camera doesn't have high DR range at low iso. An Engineers working with photographers decided this was the correct compromise. They felt it was more important to have more DR beyond iso 1600. This is a camera for people who are trying to keep the shutter speed at around 1/2000 under stadium lighting. Not for people shooting landscapes at base iso.

On a technical not the older arrangement of having an analogue is o amplifier gives better DR at high iso and lower DR at low iso. This camera has the older analogue amplifier

On article All about that lens: Sony Cyber-shot RX10 III review (477 comments in total)
In reply to:

unbelievable: I kindly have to disagree on calling the RX10 III an ideal hiking camera. It definitely ticks quite some proper boxes: reach, image quality, weather resistance. But at 1kg+ it is simply too heavy (at least for me, considering that my total long trail pack weight is 7.6kg including backpack, tent, sleeping gear, clothes, raingear, snow clothes, cooking stuff, electronics, navigation stuff, medkit, etc).
Having had several lightweight superzoomes (FZ20, FZ7) but let down by image quality I moved on to enthusiasts camera (rx100, xz1, lx3). These are capable of making acceptable pics, but unfortunately do sacrifice reach to the extent that you can capture a bird in just 2 pixels.
In my opinion the optimal hiking camera is currently the tz100. It has respectable reach, decent image quality and most and for all, it is truly portable (small and lightweight). It neither excels nor fails in any field

Not an ideal back packing camera. But that still leaves day hikes.....

On article Setting new standards: Nikon D5 Review (505 comments in total)
In reply to:

endofoto: This is a very good camera. However crop sensor 1000$ Nikon D7200 has much better dynamic range value (D5: 12,3 vs D7200: 14,6). This is a real shame. I dont understand the reason for this failure. Nikon may have decreased sensor performance to get more speed. If you dont need speed D810 is still the king for Nikon users. FF does not mean better results, for macro FF is useless, for wildlife crop sensors are much better. Money is not everything.

I think you fail to understand the compromises made. Look at the graph. The D5 has better dynamic range than the D7200 at iso 800 and above. For a low light camera that means?

Surely to buy this camera and take base iso landscapes would be a waste of money

On article Back to the action: Nikon D500 Review (1122 comments in total)
In reply to:

Old Cameras: I think customers would accept an all- carbon fiber camera body and the deletion of the auto focus motor for screw drive lenses, and the aperture ring, making this camera like a D5xxx, compatible only with AF-S lenses. They could make a top of the line camera that weighs little more than a pound.

Surely a D500 doesn't have an aperture ring?

My hunch is that you are wrong any way. I think the weight is across alot of components. Like the pentaprism, mirror motor, battery etc.

Also I don' t t think magnesium is exactly heavy

In reply to:

philo123: Since I got into photography about 6 years ago I've been a Pentax User - Loved the K3 a great camera with DA* Lenses. However my preferred style is bird/wildlife which really pushed me and the Pentax, which isn't the best at fast autofocus. I decided to sell all my Pentax gear recently to fund the D500 and the 80-400. Finally got it a few days ago. First impressions on unboxing were....Hmmm, build quality not as good as Pentax and more "plasticky" bits . However I bought it for birds etc. so I could forgive this. Overpriced? Most definitely compared to the Pentax system. Performance? Oh WOW. I am absolutely blown away, staggering AF and sharpness. Virtually every shot I've taken is sharp. I've even tracked a swallow and the AF just glued itself to the fast moving thing! I'm not used to the Nikon system yet but I'm one happy convert. I know there's lots of negativity but this is the PERFECT camera for my type of shooting. Not yours? Well, move on to something that does suit you.

At last a really helpful comment

I hope Sony improve the image quality too, by using better sensor

So just let us know how we improve on a back side illuminated CMOS centre with the EXMOOR system

I'n sure the Sony guys would love to know
