Hmm, one trick ponies that will soon collect dust.
One could think they might be collectors items, but I doubt it, the original ones, yes. But I feel these new lenses will not keep their worth. Reminds me of all these special edition collector coins, or collector decorative wall plates (with famous motifs of famous painters), that nobody buys on fleabay.

On article SainSonic launches 50mm F1.1 lens for APS-C cameras (248 comments in total)

this is nothing new really. Kamlan is the actual manufacturer.
http://www.kamlan.com.cn/ These lenses were also already announced several years ago under the Kodak/Sakar moniker, as some searching will tell you.
Sain Sonic seems to be primarily an electronics shop, I guess they are distributing the lenses now in the US. In Asia you can get these lenses already, here are some samples on a Thai forum: https://pantip.com/topic/35416488

zonoskar: Does the MTF look good? http://www.tamron.jp/en/product/lenses/b028.html

Hmm, the one at 400mm does not look so hot. Already at 10lp/mm it drops off.
But the lens is really light for 600mm.

On article Pinhole Pro DSLR lens is on Kickstarter (39 comments in total)

Pinholes are already available for purchase (for less). Not sure if the exchangeable pinhole sizes are worth it. If at least they would have made a zoom (or shift, as mentioned by someone else). yes, a pinhole can be made as zoom, just move it in a barrel back and forth. My, wait, just get a cheap bellows, and put the pinhole in front of that, and you have a zoom pinhole...

Learning from existing pictures, means so you can reproduce existing shots... ;-)
In related news: GooppleGMdak released a mobile robot that can travel for you to all the scenic locations on the earth with your AI enhanced camera to take all the nice shots that you ever wanted... They will be transmitted wireless to your TV and you can watch in real time, and change the destination if the weather is poor.
The poor masses that can't afford this, can use google streetview that in the meantime covered every square meter on the planet.

photonius: The full depth of the mount would have some advantage for technical trickery. For example, one could still have a small semi transparent mirror that deflects some light for initial PDAF focusing, and flips out when taking the picture, and stays out when servo tracking. Not sure if it would be worthwhile, on screen PDAF may soon catch up.
Or a a second small sensor with a much smaller pixel spacing (for simplicity sake, say a mobile phone sensor) mounted on the side, and a mirror that can be flipped in to use that sensor. Suddenly, your body will now have a crop factor of 5x or whatever, for those birders (only in good light of course) - anyway, just a crazy idea anyway.

@ Kerensky. No, not a full mirror. The camera works by life view. It's basically only the secondary mirror behind the main mirror that I'm talking about, that reflects a small fraction of the light to the PDAF. So, a small semitransparent mirror that can be flipped out permanently if not desired, or could be used for PDAF. Less weight, smaller, less mechanics than the full mirror with its secondary mirror. But I'm of course not sure if it's useful - it just could be a stop-gap until sensor PDAF is fully matured (if it ever can). Just wanted to say, with the space you have you could implement such gimmicks.

In reply to:

mosc: Also if we're talking about EF vs FD, why does it not mention the infuriating self-imposed limitation of the wider EF-S mount's throat preventing using those lenses on an EF camera??

Probably more of a litigation issue, i.e. so that people don't sue Canon when the rear element bumps into the FF mirror. Canon does take advantage of the fact that with EF-S they can design the back of the lens a bit closer to the sensor. Third party does not design into the mount, since they want to mount their lens on many different brands.

So many network things in there that I don't care about. But no GPS.
Stuck with Sony then.

In reply to:

thx1138: Didn't Canon get the memo, this market is dead and buried. Smartphones have sensors this size now and sure while they don't have optical zoom yet, the IQ has improved dramatically, just look at S7 and Pixel.

Canon should focus on 2/3" and 1" sensors for its compacts and frankly I don't want or need 1000mm equivalent in a tiny camera of this class where the AF sucks anyway. Make it a 1" sensor with a 18-200 f/1.8 FF equivalent, and sign me up now.

the optical zoom is the huge difference to a smartphone. Can't replicate that with a smartphone. Yes, maybe not optimal at the tele end, but a lot better than a wide-angle shot from your phone.

On article Photokina 2016: Olympus E-M1 Mark II overview video (280 comments in total)
In reply to:

Gazeomon: For Olympus users the EM1 II maybe a tempting camera to upgrade to. The stats and the camera features look very good, but I don't see any compelling reason to switch from any APSC system. The size advantage is negligible and the image quality maybe comparable (at best). Olympus's 'pro' lens offerings although very good quality are not exactly compact either. I would consider Olympus if I would not be committed any other system.

If you take a Canon 80D, Samyang(Bower) 8mm fisheye, Canon EF-S 10-18 (16mm FF equi. UWA rectilinear), 18-55, 55-250, Canon 100-400 II
you get 7.8 pounds. The reach at the long end is virtually the same since the 80D allows a bit more cropping (compared to the mark ii), reducing the Oly tele advantage to only about 10% more. Given the better sharpness at the long end of the Canon, I would guess they actually give similar results at 400mm.

that's the future. Not only software renting from the cloud (Adobe etc.), but now also hardware renting, it will die whenever companies decide.

hmm somehow i thought it was a different cover.

Hmm, I guess they forgot about the basic principles of photography. Who wants extra flare reflecting of shiny golden inside surfaces....

hmm, while nicely done, I expected something else from the title, i.e. the same view of the skyline in time-lapse over three years. These are just cuts and edits, all could be done over a very short time.

gag...

... and now, how about a pain by numbers camera with touchscreen to select what picture you want. No actual landscape needed.

In reply to:

photonius: As pointed out by SickVodka, it's not really a Swiss company. To summarise findings of many people: The Swiss person (of the two person shareholding company) is involved in several other companies, the location in Baar is not surprisingly in the canton with the lowest taxes in Switzerland. Many other international companies locate their tax headquarters there. The Foreign Investor of this company is Polish, and is the owner of foto-tip. This was actually one of the key companies to bring the Samyang lenses to Europe, the first European Web site for Samyang was Polish. So, it looks like the IRIX brand is simply a high class product from Samyang. Not sure if Samyang themselves will come out with this product, or if this is really the brainchild of the Polish entrepreneur to make improved Samyang products. Samyang still sells their lenses to other resellers for rebranding. But Samyang has now established its own reputation, maybe now branching out to higher level (like Lexus vs Toyota)

Thanks for this extra tidbit Astrotripper. Yes, indeed, the polish Samyang web site disappeared. And foto-tip has a clearance sale of the Samyang lenses (for good?).
