Robert Soderlund: In the last balloon picture, doesn't it take few milliseconds for the sound to reach the flash at a meter or two? How did it fire in time?

Because it takes much longer for sound than 1/20000 seconds to reach the flash in the first place, since it was probably positioned a few meters from the target. Sound travels approx 340 m/s indoor temp, yet the explosion is in its starting stages. It takes 1/340 of second for sound to reach a flash a meter a way, by that time a burst would no longer be in the starting stage i believe, i could be wrong, any ideas? Add to that possible millisecond reaction time of the electronics involved.

oscarvdvelde: Looking at the full gallery, the panel will have a hard time going through the images. Of the 10 pages only a minority of submissions qualify as scientific photography.
http://rps-science.org/competition/all/International-Images-for-Science/entries/?page=10&sort=&category=&competition=1

I agree, it seems its half biology which of course is science, but mostly it seems to just be fine pictures that can have something to do with science. They are very basic pictures that try to cater for everyone, not particularly for science oriented people. Many true science pictures can be very boring for someone who does not understand it, and very interesting for someone who does. Like a microprocessor, or anything that doesnt exactly say anything except for the scientist. Butterfly pictures for example could only be called true science for 9 year olds in school.

I dont quite follow, setting a shutter even to 1/8000 would not suffice, it is the flash that illuminates the scene making the sensor capture only what happens during the intensely short flash duration, the shutter itself has minimal difference, we are talking tens of times shorter duration than shutters can do.

Any idea whether current version supports Sigma 18-200mm C model?

As usual these capture the moments where a certain expression has nothing to do with reality, but rather the emotion the photographer tries to express. If a person has a certain look, he too often chooses that photo and thinks it expresses the situation of the population in question.

Emotion in photography should in my opinion have no weight, what photography does if done correctly is documenting the facts, not twist them and make people draw conclusions of a certain second in a certain war that could take years. Its the experience of suffering that is bad, you can only capture part of it, the emotions are not to be taken in pictures.

For example, everyone who has been ill knows that taking a picture of themself does not explain how they felt during that illness. If you however got blue or pale, thats where photography comes in handy, to bring out the truth, not how your lips or expression was during a certain time of the day.

I dont understand why people bother to look for sharpness in samples that are sharpened, if one would want to critique a picture one would view unsharpened unprocessed RAW or unprocessed JPEG output. Lenstip is one of the only ones that uses science over beauty in samples. When you put "real world samples" on the web its just marketing how it CAN look, not how it performs as standard.

If it would be with a viewfinder i'd understand how it would be more stable and more enjoyable to shoot with than simple "knuckles to skull" shooting. I do not see why it has such a grip, but there must be a reason, until i understand i will not mock it, but when i do, i just might.

Well at least rotational shake is minimized with such a wide grip, especially for a left eye shooter, other than that i don't know.

Simply put i'm sure many agree, these are images, not photos.

On Nikon AF-S Nikkor 35mm f/1.8G Lab Test Review preview (79 comments in total)

D800.. which one is measured here, the camera or the lens itself? Pretty hard to compare lenses when the tests are done on different formats and cameras altogether.

Must have some sort of a standard, as in same camera for every lens.

Volkan Ersoy: Looking at samples in Steve Huff's review, it's sharp enough wide-open in the centre. However it has a strange bokeh character with blurred highlights having a swirling effect. Many viewers say it gives dizziness. Also, the lower parts of bokeh halos are missing, compared to Leica's Nocti. Huff claims it is close to Noctilux and Hyperime in 3D pop and sharpness though bokeh can get odd at times.

Indeed, get close enough and nail the focus or you could stay shooting studio if bothered with OOF things.

"Bokeh shmokeh" as they say, stop it down and bokeh no longer bothers if there is enough light. Bokeh seems to be some sort of sensor size thingy these days, smartphone users want it, slr users bother more than ever in the film days about it.

Robert Soderlund: This is in my opinion how people should do photography these days, not censor out things with bokeh and unrealistic post processing which makes pictures graphics and not photographs.

Photography is about catching the moment, not feed people your own ideas how things in the world "should" or how you would "want" them to look.

I think you are trying to be funny there with your statement on the bokeh. Seriously speaking we cannot "oust them from photo" only time will ultimately show us what photography is all about.

I rely on lenstip myself, waiting for their review.

Perhaps we can see something that is "Nothing to carp about" and "simply sensational" along with "deserves our praise" or to have "any reservations".

Joking about the wording, but lenstip tests without sharpening.

webrunner5: Crap skin tones and crap video and it gets a 80 score??? Wow, someone at DPR REALLY likes Fuji's.

Ultimate image quality is always number one in thousand dollar cameras, no sane person invests that amount to just take snapshots.

I just will not believe that there is 5 high ranking people in Canon that REQUIRE translation, are not the higher ranking ones usually quite knowledgeable of english, since its kind of useful to know especially in the marketing department.

jon404: 3X the price of the new Pentax 645D-II... same 50 MP sensor? What am I missing here?

A hell of alot of people in this world do not eat much anywhere except what they can, going out to eat and riding bicycles is not even everyones luxury.

Therefore it is obvious that this camera is marketed for people with too much money, that find Pentax to be just a soup kitchen.

Marty4650: A dream job, if ever there was one for a photo enthusiast.

And he actually gets paid to do it!

For some being in a basement AND working AND getting paid is all that matters, for others they simply get bored too easily.

zither: OK, everybody acknowledges the sharpness (score) is partially because of the A7R 36mp sensor. But what about A7? I think it's more fair to compare this FE 55/f1.8 on A7 with 50/f1.4 on Canon 6D and Nikon D610. They are the most popular (affordable) FF cameras + standard prime lens bundles and the overall prices are in the similar price range as well.

It has more to do with pixel density over the area the image itself is cast, smaller circles tend to be sharper (micro 4/3) than full frame image circles. In the end the result is what matters, full frame is less densely populated with pixels (often).

If we would measure purely resolving power, a microscope lens would obviously outresolve a large format lens.
