ondrejbobek: Where is the button "i want it"? :)

I understand and respect your thinking, but I still think I would get that car in stead of the just in case of cyclists kit.

obsolescence: Great. Now, please put a T-S mechanism in the back with a MFT mount, and we'll have a nice T-S architectural lens for MFT.

seeky: For architecture its the shift function that are the most useful part of the TS mechanism. Shift is absolutely possible to do in post processing. The result is the same if you shift the lens or shift the sensor. Or use a larger sensor and do a shifted crop. Some IBIS cameras even have a built in a user adjustable sensor shift function that works just like a shift lens.

But I agree that the tilt part isn't possible in post processing.

thx1138: Hopefully low coma for astrophotography. Also I've read from field tester the distortion is very low and from 5.6 it gives the Canon 11-24 a run for the boatload of money it costs.

Low distortion seems to have gone at the expense of low coma.

In reply to:

TyphoonTW: "Venus Optics says that the lens has almost no distortion".

If that's true, and if coma performance turns out to be at least somewhat decent, this lens could be very succesfull. Is the extra 2mm worth the extra 600~$ over the Samyang 14mm f2.8? We will see, but definitely worth keeping an eye on this.

Well, the coma performance is not exactly stellar at f/2,8, but it could be worse. Calling it decent may be a stretch.

I'm definitly waiting for a Irix 11mm f/4 review before I make up my mind. Samyang 12mm f/2,8 may also be a lower cost alternative if low coma is more important then low distortion.

Why? Just buy a full frame camera and do a post process 4:3 ratio 2x crop at the left side, right, upper or lower side or one of the corners.

Where is the button for "I want it for free - and trade it in for Pentax equipment plus a nice car"? :)

On article Comparison Review: Sony FE 50mm F1.4 ZA vs 55mm F1.8 ZA (225 comments in total)
In reply to:

SimenO1: 1000$ for a full frame nifty fifty 1.8 are a ridiculous price. Also considering its performance. Similar lenses for other systems cost 100-300 $.

It also defeats one of the main points about mirrorless: small size and weight. This is the longest and heavies in its class.

That leaves me wonder even more how few would buy the 55/1,8 in stead of the cheaper 50/1,8 or the better 50/1,4.

ijustloveshooting: I payed 92$ + shipping for my full frame DA 50mm f/1,8 and its optical quality is comparable. Lower build quality, yes, but it focuses fast and accurate and are sharp corner to corner wide open.

Bhima: The Sony 55 are not perfectly sharp ether. The optical performance is comparable. Wide open, corner to corner.

Obelix: That full frame priced Sony lens are only APS-C, so I don't consider that comparable.

On article Nico360 to be 'world's smallest' 360-degree camera (24 comments in total)
In reply to:

webber15: @creaDVty...I'll admit there are probably some good uses for 360° cams...it's just that pretty much all the images I've seen so far are just plain weird...

Another words I've yet to find a way to look at these images and see nothing more than...well...a squeezed perspective - it just doesn't impress me...

VR classes. Google cardboard or something better and more comfortable.

In reply to:

Evolusion: You can get better quality - more resolution and no parallax error - for less expense by shooting 360 degree with an ordinary action camera and a 3D-printed panoramic head like Panohero-Pro for spherical panos or Panobaby for cylindric panos. It needs a tripod and it gives you HDR as well if you want to.

Well, most action cams are more expensive, so why bother to do it that way? Action cams will give parallax errors too. Both Nico360 and action cam photos may be corrected for that or they may use other projections like for example little planet. Yes, you may get higher quality by stitching, or lower quality if there is movement. Nico360 can do video. If you want to stitch videos from action cameras, then you need as many cameras as you want to stich and a lot of processing power and time.

In reply to:

Biowizard: In what respect is a 360-degree view "stereo"?

Brian

The article says Nico360 can produce content for stereo VR glasses, but it doesn't say the content produced is in stereo. You know, almost like listening to mono audio through stereo equipment.

Kamox: That was really, really cool. But the record out there is a trillion frames per second, so you can see light in motion:
https://www.ted.com/talks/ramesh_raskar_a_camera_that_takes_one_trillion_frames_per_second

That is not comparable. The Phantom flex are filming a single event. That video takes still photos with extremely short exposures, but not in a single take. Every frame is a new event. It can only stitch events that are highly repeatable into a timelaps movie.

On article Bentley creates a 53 billion pixel car commercial (183 comments in total)
In reply to:

DeputyPhoto: I think Simon Stock is a genius. He's convinced Bentley to pay him for months of work and has given them a basic landscape photo with a car rendered in the one area you can zoom in on and convinced them it's a 53 billion pixel image!!!!

I wonder if Bentley knows or if they will be surprised when they are told its fake. If they know, I hope the photographer/editor got well paid for lying. If they don't, it probably wasn't such a genius move from Simon Stock.

In reply to:

Reactive: That is so obviously a 3D render that has been dropped into the bridge image, what was the point of the exercise? The bridge is blurred but the B on each wheel hub is pin sharp and the right way up. The hideous 2-tone Ford Cortina paint job also looks fake, as does the hard shadow around the car.

Its not a 3D render, but the car itself is a stitch, as oppose to the rest of the image. The stitch is done on a parked car and reflections and spinning wheels are fake. I call it a medium editing job and a good hoax.

Because marketing lies makes me wonder how much else of the marketing that are lies..

Pretty peace of hoax.

- Clouds reflected in the back window and paint does not match the clouds in the larger view.

- The lens flares show the large image is a single exposure, no stitching, except the car.

- The car itself is stitched. Evident by the stitching errors on both A pillars. And how do you stitch a moving car? Well, you don't. The car can't move when the stitching technique is used. Spinning wheels are added a different way.

- Motion blur on the vertical wires but not on their reflections..

I wonder if Bentley believes their customers are fooled by first glimpse? And if they think marketing lies increases their credibility?

In reply to:

tobicy68: Does it really look that big? Looks pretty small to me compared to Canon/Nikon/Sigma 24mm F1.4 and on top of that it has splash proof. Add power OIS and you have a perfect lens for vlogging but don't think we'll have it. Yes equivalence-wise the DOF is equal to 2.8 in FF but in terms of speed it's a 1.4 not 2.8. Too bad I already have the Fuji 16/1.4 WR so I won't be interested in this in the short run.

Yake, you should read what equivalency is all about.

12mm f/1,4 1/100s ISO 200 on mFT

equals (in terms of FoV, DoF, noise and motion blur)

24mm f/2,8 1/100s ISO 800 on FF

In other words, if you have another camera, you will get equal images with a cheaper, smaller and lighter lens. Oh, except for the resolution and micro contrast that would be better on FF. In yet other words the mFT system does not offer an advantage in IQ, size and weight in this case. It may for other cases, but not this.

In reply to:

SimenO1: Comparing to the equivalent offerings from Canon and Nikon (24/2,8) the Panasonic are:
- the longest
- the widest
- the heaviest
- the most expensive

Astrotripper: Sharpest? First of all that is purely speculation as we don't have any good side by side comparisons yet. Second, that is highly unlikely that a large aperture lens is very sharp at its largest aperture. Third, the sensors it may be paired with is not up to the resolution of its bigger brothers, so that makes it even more unlikely that it may compete on sharpness.
