Old Cameras: I wonder what the design life is for these very complex lenses. Lenses used to be pretty simply and were strictly mechanical and all or mostly metal. A cell phone, for example, doesn't really have a useful life of more than 4 years - and that would be an old phone. But lenses are traditionally thought of as long term investments that hold their value better than, say, a camera body. Any of these lenses, after a few years and perhaps after being discontinued from production, might be one good "thud" away from becoming completely worthless. Especially if repair is either unavailable or prohibitively expensive.

Hmm okay. I had hoped that they studied half a century of lens technology to know how to build robust designs.

At least Samyang's manual focus will not break. The lenses that use electronics to drive focus even manually are bricked once the electrical system fails or when the mount is no longer supported.

It looks huge on the outside yet fits only 3 items with a lot of useless space above them.

FuhTeng: E-mount ain't got no lenses! I need me a wide angle prime to shoot my cats from 6 inches, this just won't do for my needs! And who thinks f/2.8 is acceptable for wideangle! I demand a 16 mm, 4 inch minimum focal length f/1.4 lens!

he asked for 16mm F1.4 and E-mount also includes APS-C format, so there you go.

oscarvdvelde: These "soap bubbles" look dense and not very 3D.

Yes indeed. But why do they not choose sample images that show the best the lens is supposedly capable of?

Switch to Fuji ;)

photophile: The dog picture made me feel like I had just just fallen off one of those playground roundabouts - which some older kid had started to turn really fast! So yep - the effect is a bit stomach-churning. Wonder if you can control the extent of swirl.

Same here. I have liked swirly bokeh photos from vintage lenses, but these are too much for my brain and stomach to cope with...

Interesting how the sample image on the right also has a darker sea.
And a reduced microcontrast.

On article Beta: try out our new 'light' color scheme (598 comments in total)

Good that it will be a switch. I like dark tones, it is relaxing to the eyes among all the white pages, documents, email software and file manager windows. Especially at night when humans should avoid exposure to doses of (blue) light which suppresses melatonin release. If you correct color and brightness using software like f.lux, white pages look like ugly yellowed old newspapers.

Imakefoto4U: Frickr is okay mainly because there aren't any other sharing sites that are better to participate in. You used to have to pay to post anything larger than 2048 pixels. Now it is 'unlimited' so paying doesn't give you much except statistics. There should be a way to run it at a profit and keep members happy or at least satisfied.
The one annoying thing to me is that the majority of members disable downloading so the largest you can see is 2048. That isn't wide enough for panoramas. If they can solve the sharing restrictions it will be great.

a Pro account used to be worth for keeping your older posted photos visible for anyone. The free account was hiding them after a few months. So, I'm still a paying member, but I now don't know why I would need to renew. Only for stats? Because ads I block anyway. I'm afraid Yahoo doesn't get any longer revenue from Flickr.

Perhaps marry Flickr with Vimeo. The style is already very similar.

oscarvdvelde: I feel all these shots could be made stronger.
The iceberg image would need to be cropped more tightly from bottom and top.
The lighthouse needs to be composed with slightly more land and less sea, and more central position so that the basalt radiates toward the lighthouse.
The tree shot looks better to me when cropping off the bright top till the curve in the dune.

@ Tungsten Nordstein
Okay here are my interpretations,

I actually feel the panoramic crop enhances the symmetry. I would put this on the wall instead of the original.
The desert was cropped both from top and bottom. May feel cropped at first, knowing the original. But then I start to like it better.

If the iceberg reflection was like a mirror, it could have worked. When it is wavy, I prefer to appreciate the wavy part of the reflection and the details of the iceberg. Now either is too far away to appreciate their details.

Cropping off the bright sky eliminates the divided focus between light source and the shadow, without losing the parallel with the beams. It removes what is predictable to make it more mysterious.

It's amazing how the camera looks like a miniature next to the bag, and then hardly fits in...

On article UPDATED: CP+ 2016: shooting the Pentax K-1 in Yokohama (377 comments in total)
In reply to:

zakaria: I like the conceive and valued report except the conclusion!!!
K1 is not at league with d610 or 6d .both last camera are entry level cameras and outdated. You even didn't put it in d750 league.
The fair compare is D810 at least both are handling 36 mps sensor
Both are 1/ 8000 shutter speed both are well made bodies not a combination of plastic and ss. Don't forget the Pentax unique features that you already have mentioned.

I would actually be very surprised if a Canon EOS 6D II would come out at that price and with similar resolution and special sensor features (stabilization and pixel shift resolution). The 6D hasn't even got a tilt screen yet.

On article Special K? Pentax K-1 First Impressions Review (975 comments in total)

This looks like the innovative camera I was hoping Canon would make, when I wanted to upgrade from my EOS 5D. Instead they came out with a high-priced autofocus monster 5D mk III and a crippled 6D (5D mk II mk II)

Dudeist: Wheel reinvented - 35 mm lens with full frame camera is good for some portraits.

@Timbukto the Fuji 23mm F1.4 is $700. The Samyang 21mm F1.4 is just $350. There is a 17mm F0.95 for m43. It is not that difficult to find... An equivalent 35mm F2 on full frame DSLR is $550 and roughly similar in size/weight, but in shutter speed you lose a stop.
