At what sort of focal length or field of view is this, the moon can be seen quite a distance from earth, many millimeters, and the distance to the moon is approx 300k kilometers. Now Saturn is 1.2 Billion kilometers away from us, so its 4000 times further away than the moon is. Therefore this picture actually understates the distance Saturn is from us.

Karaya: "anyone that still blindly fetishizes the words 'made by hand' should try shooting with the EF 16-35mm F2.8L III sometime."

One could just as well turn this around and say: "anyone that still blindly fetishes the words 'made by advanced automated processes' should try shooting with one of the Canon broadcast lenses sometime"

Yes somewhat, but mostly people shoot DX and simply come here to drool over what exists, and end up buying value for money items like SIgma C. Not Canon L

Most people talk about the premium ones, when realistically only few people can actually afford them, the 100-400 is the real gem, it will perhaps replace the current 70-300 for many people shooting dx.

Don't we humans have predator vision with our eyes facing forward? Just look at horses and deer, they got their eyes on the sides.

Very good, but sounds a bit too artsy like for my taste, i rather join the non photogs on my bar visits, just like old people dont want to be called old or necessarily crammed with other "old" people.

Papi61: Every mid-range Android has 1080p nowadays. I wouldn't call anything without a quad-HD screen a "flagship."

Brand Oppo players however is kind of different from the mobile manufacturer from what i know, i could be wrong and cannot back up my statement, but this i've heard.

How to know when lens technology has come far enough? The answer is when someone deliberately does lenses that are of bad optical performance. Calling bad lens design art is ridiculous, vintage simple lens designs were not considered artsy with their aberrations then, why should they now?

Robert Soderlund: Oww, this hobby can be expensive, for that price one can pick up one or two very capable DSLR's used, and that 500 is just for a flash. Getting a macro lens with that and its a grand or so.

I dont seem to ever get my point correct, whenever i post someone posts something to counter my personal opinion. I would end up with 3 bodies, but the point was not how many DSLR bodies you have. Point was simply that 500 can get you loads of photo equipment. and no some OEM flashes might be 500 but for 75 you can get bounce flash easily. Just because they are going for 500 doesnt mean you spend 500 and buy them, the consumer chooses not the producer.

Mirror speed is never as fast as shutter speed can be, the video does not remind the viewer of this.

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.
