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!

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!

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.

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.

On Pentax K-S2 added to studio scene article (73 comments in total)

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.

Mac McCreery: Pentax do seem to make photographer friendly cameras. I have handled many brands in my local Jessops in the Uk (the Birmingham branch). The Pentax is my preference. We all have our own preferences with regard handling. I guess that Pentax have announced these lenses first as users often complain of the lack of longer telephoto zooms.

As for Pentax not having a good lens range- I find that an odd and unfounded argument.

Dear Barry (Pentax has weird zoom lens portfolios)

On that one I agree fullheartedly :-) It seems they forgot to pull some older full frame lens designs :-)

Dear Barry, (why the hell I wrote so much)

I replied to you in the first place as I misunderstood your complaint as the typical non informed poster who does the typical Pentax bashing.

Instead you know more about Pentax zooms than I do. I use primes.

I see your points. They are personal and they are understandable. Not every photographer will see it the same way though.

I guess I wanted help that others reading these posts do not discard Pentax simply because of personal statements that their lens range is no good.

I think the Pentax lens range is no better or worse than others. It has its weaknesses and it has its strengths, which makes it a valid choice among many great photography brands.

Dear Barry, (about DA* 16-50mm and DA* 50mm-135mm)

16-50 mm is the APS-C equivalent of 24-70 mm. and 50-135 mm thus is the equivalent to 70-200 mm. Both zoom ranges are standard zooms for Full Frame and this split is well accepted in the industry.

However, Canon has the 24 to 105 mm f/4 and many photographers love this lense, evern it is relatively slow and not optically superb, but it has a zoom-range that many find perfect.

As you wrote, I think many photographers can discuss this to death and never come to a conclusion.

Myself I shoot primes, as I like the higher quality and nicer bokeh.

Dear Barry, (about Ultra Short Zoom)

The 8-16 mm Sigma is superb and it is available in Pentax K mount: http://www.sigmaphoto.com/product/8-16mm-f45-56-dc-hsm

To my understanding 8-16 mm is not available by any major APS-C Brand, so Pentax is not better or worse than others.

The 8-16 mm from Sigma is without peer, so if this is your thing, this is the lens to go for.

http://www.photozone.de/canon-eos/515-sigma816f4556apsc?start=1

I am as excited as you about the new Wide Angle Zooms Pentax has announced. But I am worried that as for Full Frame they will be rather big. What is attractive to me is the small over all size of Pentax APS-C Camera plus their small prime lenses.

Dear Barry, (about weather sealing)

Thanks for you in depth reply. My comment was meant on optical quality. If you consider to include weather sealing, this is a different matter. But to be fair, many competitors do also no have a complete zoom range AND weather sealing.

Please note that I should with my Pentax gear regularly in adverse weather conditions and never had a problem. None of my lenses are weather sealed. Here is my trick, it might be useful to you:

- After every shoot place lenses and camera in a dry cabinet
- I set my cabinet to 30% humidity, this dries out any gear, I found 50% not to be sufficient
- Always unmount lenses from camera, so humidity of camera can escape through lens mount
- never mount the lens cap on lens mount, so humidity of lens can escape that way
- place camera lens mount and lens mount of lens down so no dust goes in

On Olympus OM-D E-M5 II First Impressions Review preview (1392 comments in total)

Compliments to great writing on "First Impressions" and "Shooting Experience". For me every camera is technically good enough, but handling of most cameras clearly is not. Thus (for me) these pages are the most important pages in any review. Keep up the good work.

Personally I would even enjoy more pages about handling and less pages about Image Quality and technical details. I did not even looked at the IQ pages. Again, all cameras good enough for me. I am shopping for a camera with better handling, not with better IQ.

On New samples from the Sigma 24mm F1.4 DG HSM Art lens article (230 comments in total)
In reply to:

Jonathan Wilson: Looks great. I'm certainly looking for something around this focal length but sadly there are apparently no plans to make this in Pentax mount.

They should consider, period. My absolute favorite lens is 35 mm f/2 and I shoot it open almost all the time. There is nothing to go wider and stay open. The Pentax 21 mm is an excellent lens, but it is only f/3.5. The Sigma 24 mm f/1.4 makes perfect sense on APSC. And Pentax is a much bigger market than Sigma expects, as there are so many Pentaxians shooting with prime lenses! I wonder if Pentax User base * Prime lens users > Canon User Base * Prime lens users? So the Pentax lens market for prime lenses is actually bigger than the Canon one!

Direct link | Posted on Feb 22, 2015 at 04:13 UTC

Maybe when seeing how big Full Frame Lenses suitable for sensor shift image stabilization are will cause a good thing: A lot of those who cried for a Pentax Full Frame camera for so long might realize that APS-C has its place. It provides a great balance: You can bring a complete range of lenses in a shoulder bag versus a full fledged photo back pack!
