Fri13: The video is falsified, it shows recording from the moon, but you can hear wildlife on soundtrack. Everyone knows that space doesn't have air, so the moon wildlife could be heard from the moon to earth.

You can clearly see rotation of the earth in an exposure as low as a 25 seconds with a 24mm lens. It's an annoyance that will cost you considerable cash to remove with various tracking gear if you get into astrophotography. This entire video is a marketing gimmick for ignorant amateurs with too much cash and gear acquisition syndrome.

Prixnobeldefoot: wish they had included a bigger flash, 12m range is a bit short for my astrophotography....

Yes in real time is not an exaggeration or rhetoric. In this video ISO 204800 looks best to me for seeing dust lanes etc. in the milky way. Taken with a 50mm f/1.1. My jaw dropped. Of course you'd use lower ISO for actual hi-res image capture.

Sammy Yousef: Terrible timing. Most who want to do astro are drooling over the innovation on the A7R of being able to see the Milky Way in real time at ISO 409,000.

Astrotripper, here's proof by counter example.

I encourage you to take a look at the full sized images. Now what is that you were saying?

Sammy Yousef: No thanks. OVF when shooting action...at least until OVF is killed off or EVF genuinely becomes better than OVF.

Ok I'll have to eat my words here and apologise for being incorrect. I wasn't aware Sony had managed to do this:

Moonlight isn't extreme. An OVF handles it fine. Try doing some wide field astrophotography some time. You're trying to avoid moonlight! And a high ISO EVF will be very little use.

On Panasonic Lumix DMC-GF7 flips for selfies article (390 comments in total)
In reply to:

whyamihere: I like the adorable grumpiness and lack of awareness of the anti-selfie, anti-social media crowd. It's as if nobody in the history of the world ever photographed (or painted, or sketched) a self-portrait, published that picture in a public location for all to see (like an art gallery, or an online portfolio), or shared their photos with friends and family (photo albums, 35mm slide shows).

It's not narcissism. It's the same thing as before, just in a form you're all uncomfortable with because you don't know how it works.

It's those who excessively take 1 person selfies, often at inappropriate times, that give it a bad rap. We had people taking selfies outside a cafe that was under seige by a terrorist in Sydney Australia recently. And for days afterwards people took selfies in the vicinity instead of taking more outwardly focused pictures.

Just because you stand in a spot that doesn't mean you're a part of the story, or a part of history, or should be the focus of the situation. These people are missing the point. An analogy: Going to an airshow to take photos your own ingrown toenail.

Sammy Yousef: You can't sweep things under the rug with such assurances.

1. There is cost and inconvenience to the customer. Some will have a much harder time than others getting theirs serviced. Some will have to wait for a long time without a camera. Some will have to pay shipping. Some will be out of luck because they bought grey market.

2. Nikon will recoup the cost of service from subsequent sales. Which means customers pay more again.

3. There will be shots ruined. That is not and never will be the photographer's fault. Cameras that can't autofocus properly or have internal reflection issues are squarely the camera company's fault.

4. It's not the first time. There have been a long line of issues with Nikon camera. D70 blinking green LED of death. D80 exposure issues. D7000 focus issues. D800 focus alignment. D600 should be sold as a vacuum cleaner. As more customers get burnt, more move to cheaper options like their phone. The camera companies only have themselves to blame.

I think advanced users would enjoy the ability to setup a presribed focus chart in a prescribed way and for say 3-5 different focal lengths and say 3 distances (near focus, mid distance, infinity) enter an AFMA value.

Something like
f dist AFMA
70 near -2
70 mid -2
70 inf -1
100 near -1
100 mid -1
100 inf -1
170 near -1
170 mid 0
170 inf +2
230 near +2
230 mid +2
230 inf +3
300 near +2
300 mid +4
300 inf +5

Details would depend on how wide a range and other factors. Camera could confirm dist and focal length roughly correct. Taking 15 or so shots or validating with liveview view dot tune would be time consuming. Only dedicated users would do it. But much better than having to take it in to the factory at least where I live as there is a long lead time and you're without the camera.

No it's not. What's the point in microadjusting at 70mm if it doesn't focus properly at 200mm...or vice versa? The best you can do is even out the blur between 2 focal lengths you use commonly...or you could go back to a prime which you have some hope of adjusting perfectly (assuming it doesn't differ by focal distance)...

I repeat MFA as it currently stands is a kludge. It's better than nothing....JUST. What you need is a value based on distance and focal length for each lens. Then you can nail it. But it's not a perfect world.

All that said I will agree with you that +4 is not a lot. Expecting better is as reasonable as expecting perfect sharpness. But for larger variances MFA doesn't fix the problem.

Well I'm certain you understand this better than me. Try a 70-200 f/2.8 zoom lens instead of a prime? How consistent is that micro-focus adjustment across the range of focal lengths? Or do you have to MFA for a specific focal length and compromise at others? As it currently standsa MFA is a primitive tool for zoom lenses. You need to be able to set numbers for at least 5 points in the zoom range. We may see that one day...or CDAF may take over - I'd guess the later.

You don't do the camera companies any favours by convincing people the problems are small. QC continues to go down because those companies temporarily find themselves getting away with ti. Then you reach a saturation point where too many users have been burnt and sales crash with very little hope of medium term recovery because you either burnt professionals that had to manage a client's expectations or you burnt amateurs that often save up for months or years to get their gear.

Photographer2: As a former D600 user and now Canon 6D I know I made the right choice.
It's not even worth reading those "reviews", much better taking pictures and good not having to worry about quality issues. How many models after the D600 came out for Nikon to get it right with the D750?... And still no D300 replacement...

Sadly your faith is misguided. Take a look at the autofocus through viewfinder issue the 70D has. I would have bought it otherwise.

https://www.youtube.com/watch?v=cA6JnzYSDJE

I have been a Nikon shooter since 2005 and I now own both Nikon and Canon bodies. I will never buy a really expensive body and I'll never buy one until it has been thoroughly tested (at least 6 months, preferably 1 year after release). All the camera companies care little about the consumer. You just have to look at some of the responses people have been getting when they've complained.

ealvarez: D750 is basically 5D Mark III with

Better sensor
flippy screen
Wifi
-3EV focusing capability
Highlight weighted metering
ability to spot meter exposure with focusing point from other than middle
Better auto ISO system
Face and eye recogniton

and

$1000 less money.

And you still complaining for flare non-issue that Nikon will be fixing for free? Seriously?

Is it a non-issue or is it an issue they'll be fixing for free? I really must insist that you don't contradict yourself at least within the one sentence!

"Better" or "just as good" depend entirely on what you're shooting. Under the right conditions and in the right presentation media the phone will do nicely next to a much more expensive DSLR. If you're buying a DSLR purely to take medium wide angle photos in bright even light only to post them on social media then you may well be wasting your time.

This accessibility is fantastic. It allows people to play with framing and composition without an additional financial outlay. It means where 10 years ago you'd normally be caught out because you didn't have your camera with you, you MIGHT just have something suitable sitting in your pocket to capture that shot.

If that moment you're capturing involves long zoom action sports, wildlife, astrophotography, architecture, extreme low light etc. your phone won't cut it and your current DSLR might not be enough. You might be able to capture something complimentary that would suit your phone. (Crowd watching sports for example).

BrumNewsPhotos: How exactly do you replicate this issue, I have taken a few thousand images on mine and don't think I have seen it, but then I don't know what I am looking for!

You're lucky. My experience with Nikon service in Australia has been to be ridiculed because they were unable to replicate an intermittent shutter issue (warranty serviceproduced video to prove it was happening with error code clearly displayed. Retailer replaced camera after 3 attempts under consumer law). Another shutter fix on another camera 2 years later required 4 trips including initial drop off for them to get it right and fix the thing. Never mind the inconvenience of having only 1 repair center within 1000km of me and I live in the largest city in Australia.

Karl Summers: This camera wasn't ready to be released prior to Christmas, yet Nikon did it anyway before the camera was thoroughly tested for defects. Now there is a major recall and Nikon is taking a huge hit for it. The company has poor leadership. I remember a poster stating the Canon 5D Mark III had the same issue, yet I don't remember a major recall for that camera.

I don't need the constant headaches that Nikon inspires. Canon may not have the latest greatest sensor tech, but at least I can rely on my camera.

And one more thing, this is what you get for buying the first incarnation of a new product line...suckers.

Except that Canon are refusing to even admit some faults. Like the 70D focus issue above. So you would be just as stuck since they won't fix what they don't admit exists.

Don't fool yourself. The camera companies have all had their customer service go into the toilet in the last decade or so.
