On article Ricoh Theta V hands-on (30 comments in total)
In reply to:

phoenix15: If it is 625 qualcomm chip, then it isn't the same inside Galaxy S8. It is similar with most motorola phone.

At first, DPReview believed/were told that it's the 835, not the 625. They corrected the text, but left the Galaxy S8 part.

In reply to:

PhotoCGI: The 4K video capture claim is misleading. Most people reading Ricoh's marketing statement will think you will get crips hi-res images as you get in other 4k video offerings.
What Ricoh don't tell is that 4K spread out in a 360 sphere result in less than 1k effective resolution. (the resolution we look at in our screen when watching the so called 4k video). To achieve true 4k video you need minimum 4 times the amount of pixels (16000 px by 8000px). The actual resolution we get from this Theta V will be half HD at best.

Since the Theta V is capturing 4K video, you're arguing against facts while accusing Ricoh for "deliveratly misleading" (actually, for not lying to their disadvantage). So yes, it would be a good idea to retire from this conversation.
Yes, you're normally seeing much less than the entire 4K spherical video... that's why I said you have to make the difference between capture (what Ricoh truthfully claimed) and visualization.

By the way, Ricoh provides samples so people can see what it looks like:

P.S. I wonder if you were similarly upset about the Keymission 360...

"Apparently technically correct"?
Buy a Theta V, take a spherical video with it and count the pixels of the full image being captured. We'll continue after that.

I'm not "arguing the point", I'm making a factually correct statement.
Failing to understand the difference between capturing and visualization of spherical images is no failure of the camera.

It's not a misleading claim, it's the truth: the Theta V will capture 4K spherical video.
The problem is that you're usually visualizing by "zooming in" and moving around the spherical image, rather than seeing it as a whole.

In reply to:

falconeyes: I am looking for no less than an Insta360 Pro lookalike, i.e. a VR camera with 6 rather than 2 lenses. And then 8k rather than 4k when stitched offline. A larger manufacturer like Ricoh (or Yi or GoPro) should be able to do that at the $999 pricepoint. Until that day, all VR offerings are either crap or scam.

Wow, you're looking for "no less" than a 3,500$ camera "lookalike"? At less than 3 times the price?
And on another post, nothing but 20K was adequate for you... isn't this just bashing?

Ivan Paganacci: Memo to Canon: Even my underwear has 4K.

20K? You're not supposed to make fine prints out of Theta images, though ;-)
4K into a such compact package, is not bad - and let's see if the Yi can do stitching as well as the Theta.

Mike, you were talking about still images of still subjects, and all the time in the world to mess with gimbal heads and whatever (and still not getting a 360 image, but a panorama). Take a look at the Theta... it's not designed for the utmost image quality (for that, you'd use a 645z or a K-1 in Pixel Shift Resolution mode), but to be very easy to use. It's designed to capture the moment... spherically ;-)

This is not a "panorama" camera, but a spherical camera capable of recording still images and video (with spatial audio). You cannot do that with stitching.

A possible solution - one investigated by Ricoh Imaging - is to combine a Theta with a much higher resolution DSLR:

4K video is a requirement for spherical cameras, IMO - since the resolution is "stretched" all around you. Unlike "normal" video, you will only see a part of it (but you're able to select which part "around you" to see).
This Theta V makes a lot of sense.

Its about time to change the name of your site.

Instead of DPreview
it should be
Nikon-commercials

Make up your mind: you either agree it is news, or you don't.

Because it is news? You know, one of the main camera makers announcing a product that wasn't available before?

wed7: Will DPR use a SILVER BICYCLE this time? Will it be necessary? :)

Thank you Ricoh for bringing this product, I hope you made some of your customers happy. BUT MORE customers will be more happy if you hasten the release of your other products. i.e. lenses. :)

The D FA*50mm f/1.4 is expected for this fiscal year - that could be as late as March.

Roland Karlsson: Many here are talking about a classic look. Make an image google search for "pentax slr chrome silver" and take a close look. This camera looks very close to a Pentax MZ-5. Actually, very close. I do not know about you, but I would hardly call MZ-5 classic. Might depend on your age :)

What I call classic is Spotmatic, K1000, MX and LX. And their chrome versions looks totally different. Much more classy IMHO. They have chrome plated brass, while MZ-5 and this are painted with silvery paint.

Since it's so hard to see a difference...

In reply to:

Triplet Perar: The comments are not on the camera, but on the unappetising behaviour of Ricoh — to release nothing — a silly, already-seen-it-hundreds-of-times-before irrelevant paint-job, on the very same day as Nikon releases their own, new and breakthrough D850. Ricoh had announced this paint-job back in February, and could release it at any date. But no, they were waiting for Nikon, to spoil their day. Got it? They are capable to bomb other company's PR very precisely, but incapable to deliver on dates of their own crucial promises. Ricoh pretending to rival Nikon, bombing their PRs and pretending to be a photography company of the same calibre goes way back in history, and this is, I think, their all time low. I am glad this "news" was tucked aside on DPR.

I think he's just looking for attention. "Truth" has no meaning for Triplet Perar.

In all likelihood, since the new cameras and lenses are still under development, Ricoh Imaging simply reserved an announcement for this period of time. It's a good way of drawing attention to the K-1.
But noooo, it must be something awful, an all time low...

Yeah, I'm quite sure none of their optical engineers were involved ;-)

P.S. By "I won't complain" I was talking about the change in materials and manufacturing methods. Sorry if I sounded in any way accusatory.

The top might be high grade plastic, though - to allow for GPS signals to get through.

I got what you meant. I guess we agree that we won't see brass except as special, purposely retro products.
I think the silver on the MZ-series cameras looks cheaper. But maybe I should dust off my MZ-6 and take a good look at it first ;-)

The last one I know of is the Pentax MX-1.
Since Pentax is giving us a better build (compared to similarly priced competitors), I won't complain.

Richard Murdey: Ah, the commemorative two-year-mark "try and juice sales by re-painting the camera and putting it in a pretty box" event.

Speaking of two years ... when was the last time Ricoh announced a new K-mount lens?

Richard, why do you have to translate? Can't you speak English directly?

That "better than nothing, by the way, has two most significant advancements for the K-mount: it's the first fully electronic (KAF 4) lens, and it has a new, very fast motor. Next would be the first truly high end primes in a while.
That being said, I'm not happy with the roadmap execution speed. But, ranting about it won't speed up the process.
