On Pentax K-S2 added to studio scene article (74 comments in total)
In reply to:

HubertChen: I was very surprised to see that the K-S2 is far worse than the K-50 in the studio comparison. When searching for the lens information I could find none.

This studio test is more of a lens test than a sensor test, thus lens model information and lens settings are very useful and lacking.

If they are present and I overlooked it, please be so kind to let me know where to find them.

@ Samual,

Thanks for the answer! Sorry that I found it only just now. My bad. But still useful! Thanks :-)

HubertChen: After reading through the comments I am very amazed. So here we have two parties:

The innovative explorers:
- Hiking 15 days up to 3500 m and work at - 10 °C
- plan, coordinate and execute 70,000 Images
- Create a 365 Giga Pixel Panorama
- Create as a vision of what is possible in Ultra High resolution
- Write a web app and establish a server that can serve such monster picture (sure can not be off the shelf image sharing app)

The Critics
- overlook the accomplishment
- criticize anything

I am not shocked by finding negative comments, but I am shocked that negative comments are the majority.

I am sad for the readers of this web site. It is not the first time here I see innovation met with cynicism. It is likely this will motivate innovators to publish their new stuff elsewhere, making dpreview a less interesting place.

@ Couscousdelight
Consider they choose mostly snow on purpose. As such they can focus on cleaning our the stitching problems in the few areas that have details. This made the workload bearable.

Besides the city will have so much smog and dirt in the air that you can not work with such a long lens as they did.

@ Geir Ove,

I found plenty of inspiration here still. Honestly speaking I find many comments of readers more stifling than the authors on dpreview. I find their few often fresh and inspiring.

HubertChen: If this law passes something as simple as taking a picture of family on a sightseeing trip could end up in exchange of legal documents and extra expenses ans surely sore thoughts about the government.

I can see how copyright owners can benefit from it. But I also can see how those who would just want to take pictures for fun will get into trouble. Is creating feelings of resentment, anger and feeling extorted in thousands or even millions of people worth to pursue this?

@ nixda
I was searching the same answers some time ago and remember well how painful it was for me to find the answers. I need to use facebook, youtube, twitter and flickr for professional reasons and finally made sense of them.

I hope you will find my answer helpful to begin your own journey using these services:

These sites are popular because they work for the people. That they are kind of free is a bonus, but people are willing to pay for the same service too. Free is not critical, that they work is.

Flickr and Instagram are ideal to share photos. Be it simply private photos between family and friends, or very serious artwork. These are new media and they work in a complete different way, offering complete new methods of sharing and feedback. Once you make these services work for you, you will not want to go back. If you have specific questions, send me a personal message. I sometimes take a bit to reply, but I always do.

brycesteiner: Affinity Designer is excellent and has saved us many times when Illustrator couldn't because of version issues.
Affinity Photo I hope will do the same.
Still will use Adobe but having another tool for prepress and design work is always welcome.

Try Lightworks. Available on a Mac: http://www.lwks.com/

Hollywood Feature Movies are made with it. You can buy or rent it. If you you publish no more than 720p its use in full version is free. Its User Interface is very well thought out.

mamupofu: I'd buy all of their lenses in a heartbeat if they'd also make a 70-75mm and a 55 macro ... there is not a single lens maker out there except Leica that makes a full line of fixed focal length lenses.

Pentax makes a full range of fixed focal lengths lenses from 15 mm ... 560 mm. They make excellent Macro lenses @ 35, 50 and 100 mm.

Samyang itself is growing a very fine collection of fixed focal lenses

Anybody who takes pictures today publishes them in instagram and flickr, which make money from advertising. As such the uploaded family pictures serve a commercial purpose and as such would be subject to a license agreement.

HubertChen: Wonderful Article. I hope I will see more of the same.

I suggest there is one more thing to consider: With time moving in Mirrorless cameras will become lower cost versus SLR cameras will become higher cost to make, due to SLR cameras involve much more mechanical parts. It is a long ongoing trend for electronics to become cheaper and mechanics to become more expensive.

@ dpreview: deng, I just spend some time editing above. After committing my edit I received the requester that it is too late to accept my edit and it was deleted.

It would be more polite to make this requester when one presses the edit button and then reject the change. At that moment no time would have been invested!

In reply to:

dynaxx: I know the DPR journalists are constrained by matters commercial but I fail to see how you can discuss this topic without at least acknowledging that the two biggest camera companies have chosen not to take a promising new camera format seriously.

It is the backdrop in front of which, this photographic drama is being played out. But for this, 600 odd passionate comments would not have appeared ( sorry, it is not your jaunty journalese, Richard).

I am sure you have an opinion as to why they have pretty much ignored MILC for so long it is impossible for them to change course ( 5 years for a decent set of lenses for a new mount ? ). Some say, it is the same mantra the cigarette manufacturers used ; "we are giving them what they want".

But aren't we are looking for leaders not followers in a business driven by technology ? Imagine the hoo-ha if Ford / Toyota had said they are sticking with internal combustion and not making electric motors.

I agree with you in that, it is curious that Nikon and Canon are not exploring Mirrorless with full heart.

On the other hand I am lost as to how this is relevant to Richard's Article? He is exploring that the difference of Mirrorless versus SLR is becoming irrelevant.

In a sense this could be the answer as to why Canon and Nikon stick with SLR. The would loose all their lenses versus not much to gain anymore. They almost can do all what mirrorless can do with their SLRS. Slab the mirror up and they have mirrorless.

HubertChen: Very amazing project! I took the tour and was astounded on the level of detail captured. Excellent execution and nice presentation.

Thanks to dpreview to find such interesting project and to bring it to our attention.

I saw several questions below as to why shoot this landscape instead of say a cityscape. The answer is that in order to provide content for 365 Giga Pixel the camera needs to be quite far away. This is why they shot with 800 mm lens on APS-C which makes it 1200 mm full frame equivalent. Close to any city and in lower height there would be simply too much dirt and moisture in the atmosphere to get a clear shot of anything at these distances. Another reason is that this subject has no movement of traffic or leaves, making stitching much easier.

Thanks for your kind reply. I agree very much!

Dear Villagranvicent,

Thanks for your kind reply. I agree with your judgement. It is still sad there is no place here for innovation, art, creativity and thinking out of the box. It would make this place more exciting. Guess I need to look for another place to to find that. Do you have any recommendations for me?

As for tech gear review, dpreview still of course is the #1 place to go :-)

On Google and GoPro unveil 16-camera 'Array' VR rig article (45 comments in total)
In reply to:

AV Janus: So how will this work?
Do they stream two streams at a given time stamp relative to my head position?
Morphing them for subtle head position changes to make it seamless?

https://www.google.com/get/cardboard/

You build a VR headset literally from cardboard, place your mobile into it. Two added lenses lets you focus to your mobile from 5 cm distance. The app uses the movement sensors in your phone to send movement data to youtube which in turn will send you the updated video stream corresponding to your new viewing angle.

You would feel that you would be positioned where the center of the 16 camera array had been and you can turn your head around 360°

In reply to:

Franz Weber: Why did they use a 400mm lens with 2x teleconverter instead of a 800mm lens in first place?

They might simply had this for flexibility. I have a 300 mm f/2.8 plus a x2 converter. I sometimes use it at 600 mm and for me it was worth this investment. A 600 mm f/5.6 dedicated lens would never have been worth it. Despite the resolution I get is incredible, can't imagine a dedicated lens to be better. Check out some of their tour spots. Some of their shorts have incredible resolution.

On Pentax XG-1 real-world sample gallery posted article (44 comments in total)

@ dpreview: 1250 mm made me curious to see the IQ at this focal length. In the sample gallery I found not one picture that comes even close to it.
