I got the camera back from service. The shutter seems to work fine, however in live view it makes a really strange metallic sound like an old mechanic camera (which might be good news). Did anyone else noticed a change in shutter sound in live view?
How are these different in functionality to Cactus?
Dimitris Servis: A word of caution: do not put junk store lenses on your camera unless inspected for fungi. A contaminated lens may contaminate your camera and every lens you put on it.
@kickoff3pm, "total" is an understatement. Ignorants say "sheer"
Dimitris Servis: "The aperture, f/8, is likely fixed." DPR, it wouldn't be a bad idea to explain what f8 really, really means to people...
People reading this article will not buy this lens
mosc: It's no accident that telescopes describe the aperture size rather than the focal length and f-stop. At infinite focus, the focal length and f-stop are both means to the same ends: More light from a small object that doesn't fill the frame. A FF DSLR focused at infinity would get very similar detail out of a 600mm f4 lens as it would a 1200mm f8 lens. They're both 125mm aperture size lenses, more commonly described as 5" telescope.
This thing can be described in the very confusing magnitudes of 2450mm f8 for a 0.50 crop (compared to FF) camera or a 1225mm f4 FF lens or better yet just a 12" aperture reflector with a rather large mount built in. 12" reflector telescopes are for sale on amazon for little more than $1,000 that are probably pretty close to this optically
Though I suppose the lens may be capable of adjusting it's focal distance to something shorter than infinity? If so that's a lot more engineering for your dollar.
Telescopes are specified by clear aperture size and f number from which you can calculate the focal length. The diameter of a photographic lens cannot be easily used in this context.
For the rest I am not sure I understand what you are trying to say and what it has to do with crop factors, but I am not sure you understand either...
What is "focal distance" to you and what distance shorter than infinity would you expect a 2450mm lens to focus on?
"The aperture, f/8, is likely fixed." DPR, it wouldn't be a bad idea to explain what f8 really, really means to people...
Why not this?
So then give it a try :)
Took my D750 for fixing the flare issue to the Nikon Swiss repair center. Got it back exactly the same, only with a white fluffy speck on the mirror.
Dimitris Servis: Hydrophobic
Not sure what you mean exactly, these are very precisely defined chemical properties, not to mention the language these terms originate from
"A hydrophilic molecule or portion of a molecule is one that has a tendency to interact with or be dissolved by water and other polar substances."
So you mean the filter molecules, will in time dissolve in the rain?
There will be a time when people will sell D600 with oil splash effects and D750 with flare issues as collectors' items.
bensherman: Is Dpreview working for Nikon by any chance? To begin with they missed the whole flare issue,then denied it and now this so called investigation (primitive compared to other review sites) that had to bring Canon in make dpreview feel good about their argument....Plain silly!
"As a consolation: they don't make 'm like they used to."
Or you never found out without the web
But that's only Nikon US?
Roman Korcek: "The lenses [...] will be available in [...] MFT mounts initially, with the company promising [...] Micro Four Thirds at a later date."
I assume this is a typo or am I missing something?
Let's hope m43 will not be left out...
Langusta: Nice lens but at least some basic electronics for aperture control and focus confirmation (like dandelion chip) should be imo included. Voigtlander could do that why not samyang? It's really no rocket science nowadays...
I think the Nikon mount is chipped
HowaboutRAW: Mr Physics+Frank C:
According to Wikipedia the flash sync speed of the D70 is 1/300 sec.
With a smaller (APSC) focal plane shutter it is easier to build higher sync speeds.
The top shutter speed of the camera is indeed 1/8000 sec.
Speed might even be the same. Exposure time is different due to the sensor size...
tecnoworld: A wonderful camera, its af performance makes me think of going back to dslr, after the poor performanve of even the best mirrorless around, but...I'll wait and see what the a9 can deliver.
I am not so unhappy with Olympus AF and certain lenses. Still, have to see how D750 does
Frank C.: That dumbed down 1/4000 and 1/200 x-sync is hard to swallow nonetheless
It is hard to swallow... That's why I wonder if the ISO 50 could compensate a little for that...
On the other hand I think that would require a differentmaybe larger shutter and would make the camera the same size as the D800/810. It is the reason why I will buy the D750 but keep my D7000
garyknrd: What a camera! Insane sensor. If Nikon had the lenses I like to shoot with. I would make a lateral move in a heart beat.
Yup, that's probably a niche not covered properly
