On article Hands-on with Ricoh's compact Pentax KP (632 comments in total)

I love the idea of a compact DSLR, something that resembles older film cameras in form factor without giving up the creature comforts of modern technology.

My biggest gripe with this camera is it could have been more compact if they got rid of that ridiculously bulky-looking pop-up flash. Heck, they could have even fit in a bigger viewfinder and still wound up with a slightly more compact body if the flash wasn't there.

Only here to make my emphatic plea for a digital GF670. All I want it to be is a medium format X100, leaf shutter, converter lenses, and all.

techjedi: Aren't hot lights considered distracting as the primary light source for portraits? I thought one of the big advantages of flash was that the model isn't squinting or reacting to the light? I feel like the picture of the guy wearing the beanie cap is showing this tension in the skin around the eyes.

That said, these look great for product shots if they have enough power for 2 lights to enable ISO 100, f5.6-ish, 1/125-ish on APS-C sensor for a 3/4 body-size mannequin.

Maybe if you had your subjects in front of these lights for an hour with no modifier, perhaps squinting would be an issue. I think it's evident from the sample photos that for quick and easy portraits, squinting is not a problem. Some modeling lights for studio strobes put out more light than this.

One of the side effects to a continuous light that many photographers overlook is the fact the pupil of the eyes is smaller. This allows for more visible iris color, which is never a bad thing. (Again, look at the sample photos.)

ProfHankD: I think the big problem with this is that good encryption isn't computationally cheap enough for the relatively slow ARM32 processors used in most cameras. Using CHDK, ML, or OpenMemories, one could probably put code into a camera to do this, but it would almost certainly be as a slow in-camera postprocessing step. It would be pretty hard to convince companies to add encryption hardware....

Actually, a lot of Flash memory cards also have ARM32 cores that could be programmed to do it... but then the camera probably wouldn't be able to review the files once written.

The capability of ARM processors shouldn't be the concern. There are more powerful ARM SoC designs available, should a camera company choose to utilize them.

I agree that the problem is: "So, this image is encrypted... should we let the camera read it afterwards?" Doing so would basically mean the keys to reading the files remain on that particular camera, and if someone has access to that camera, they have access to the files. But if the media is not reviewable on a camera, then some other data has to be provided via a common application or piece of hardware to decrypt the photos so they're readable again. Apps and hardware can be hacked, which means any encryption is basically a deterrence, at best.

There's no easy solution here, sadly.

GodSpeaks: I agree completely. Some time ago I was poopooed on these forums for suggesting people consider encryption on their computers and phones to ensure the privacy of their personal photos, videos and data.

There are some very good free encryption tools available for computers, but be wary of free smartphone encryption apps. They may not be nearly as secure as they imply. Before committing to one, be sure it does what you 'think' it does.

I use TrueCrypt/VeraCrypt on the PC and EDS (not free) on my android smartphone. EDS can read/write TrueCrypt/VeraCrypt containers. EDS does require root, however.

Encryption for your phone or computer is only as good as your habitual use of either. You're using an Android phone which decrypts your data anytime it's passed through Google's servers (which is often), and most Windows apps do the same. TrueCrypt, VeraCrypt, and EDS are, shall we say, flawed, at best, and are only useful at preventing people from getting data from a device they have physical access to and no known password. If you're freely transmitting unencrypted data across the internet by way of using normal, everyday apps and operating systems, then there's no point.

People really seem to misunderstand what encryption does and does not do, nor how to best implement it. All you seem to be doing is giving yourself a false sense of security on leaky devices with encryption apps that often do more harm than good.

I'm surprised camera data encryption isn't already a thing. We're talking a few KB of data added to each image & minimal processing power on the behalf of the camera to ensure that information remains secure and/or confidential. The media most cameras use - Secure Digital - supports encryption; a SD card's ROM could probably be modified to secure erase after too many password attempts.

With that said, encryption is only as good as its design and implementation. Companies get hacked all the time, and their cipher data could be stolen and distributed. Backdoors are made because some companies willingly hand the keys over to any government who politely asks. Heck, even the few bits of information passed back & forth between camera & the card could leak enough data for a crack. Nothing is foolproof, and encryption might just wind up being a mild inconvenience instead of a huge detriment.

Before anyone cracks wise: This is part of my job. I think about security in practical terms a lot.

teddoman: This doesn't account for the quality vs quantity issue on flickr. I almost never see a cellphone photo on flickr. That's because I follow photographers. But sure, there are users who auto-upload their cellphone photos to flickr. The vast majority of active users that I see have traditional cameras.

A statistic that tracks actual flickr usage would be camera types of the most popular Explored photos. Or maybe by raw pageviews.

I find your comment to be needlessly elitist, ostracizing, and self-aggrandizing. "I almost never see a cellphone photo... because I follow photographers," is basically a statement that insists photos can't be taken with any device a person has on them, and that not everyone with a camera is a 'photographer'.

It's equally as disingenuous to say there's a "quality vs quantity issue on Flickr" because your generally assuming everyone's basis for 'quality' is the same. I assure you, it is not.

Your alternative methods for discerning what cameras are 'popular' are flawed and easy to artificially inflate. I've never used the Explore function, for example, but I suspect it would probably throw promoted images at me rather than anything objective based on my interests. Raw page views isn't an objective metric unless Flickr wastes time separating out IP addresses and user logins to eliminate people or bots that might visit the same image a hundred times to help drive traffic.

User5477267025: Which are these certain lenses?

If it's of any additional use, I find that if the lens is equipped with a linear motor (LM in Fuji's lens naming scheme), or, as Richard suggested, if you own one of the newer small prime lenses which have fewer focusing elements, you're in good shape when it comes to fast, accurate autofocus.

It's worth mentioning the newer small primes do sacrifice some image quality. For example, while field curvature is basically non-existant on the 35mm f/1.4, the f/2 lens has significant barrel distortion which is corrected for in camera. While most people won't see this weakness if they shoot JPEG or lightly edit their raw files with a lens profile, the native flaws become more evident if you have a tendency to push your files in post production.

BBQue: Medium format starts with 6x6 cm. 3x4 is pretty boring.

Well, the largest 'medium format' sensor is 6x4.5 cm, and the cheapest camera I could find using it costs about $23,000. I hope you're also excited by parting ways with enough money that could otherwise partially finance a home or purchase a whole car and a garage to put it in...

Plus, last I checked 'medium format' technically referred to anything larger than 135 format. But facts never stopped anyone from asserting their uninformed opinions in an internet comment section, so don't let that concept get in your way.

It's medium format, mirrorless, water resistant, and there's a battery grip for this thing?!

GetUp: X-Sync just 1/125, not cool

There's also studio strobes capable of going above x-sync. The assumption probably goes: If you can afford a medium format camera, you can probably pony up for a good set of monolights.

My thoughts, in no particular order:
- This had better come with dual XQD cards
- Time to find out how few A-mount lenses are capable of resolving 42mp
- Speaking of, when was the last time Sony announced new A-mount lenses?
- I hope Sony re-worked the crummy menu system
- I wonder how quickly this thing will overheat?
- It doesn't matter how many focusing systems this camera has if Sony's tracking algorithms haven't improved
- Hey, Sony managed to go 3 weeks without announcing a 50mm lens for E-mount

MikeFairbanks: I'm often wrong (just ask my wife), but I'm pretty confident that this one is going nowhere. I can't imagine anyone buying these shirts. They're not really funny.

I get the point they are making ("let's laugh at stock photography cliche's"), but I just don't see how that many people are in tune with those stale images enough to think it's funny enough to put on a shirt.

It seems like something we would see on April 1st.

But I could easily be wrong.

I'm often wrong (just ask anyone in a comments section on the internet), but I'm pretty confident it clearly says in the blurb from DPR that these shirts are not actually for sale, and this is just an ad campaign.

It seems like someone didn't read before posting.

In reply to:

whyamihere: I think Wenmei has created the perfect gallery to help evaluate this lens. I can see how this lens can be put to good use with smart composition and some creativity, as well as how the swirly bokeh effect can go horribly wrong. I'm not in the market for such a lens, but I think this set of images is a clear testament to the capabilities of what one can do with it, if they are so inclined to learn how to put it to good use.

I'd imagine surrealist photographer/artists like Dave McKean would probably find a use for f/16 and maximum swirl. Perhaps a black & white portrait of a creepy subject, and surroundings that would be rendered appropriately nervous by this lens (a wooded area or an open field of tall grass, perhaps), might turn out nicely.

jackpro: Is the screen OLED?

OLED doesn't mean anything beyond the technology lighting each pixel. If Samsung's colors are 'weird', it's because of the subpixel structure they're using on that particular phone (which varies depending on what phone or display you're looking at).

In reply to:

tkbslc: Even on my $399 OnePlus, the reviewers gave it a hard time for only having a 1080p screen on a 5.5". And here Apple is going loud and proud with it on their $800+ model. And essentially 720p on the regular 7?

Excited to see the dual lens setup in action, though. I'd really enjoy a 56mm FL for portraits.

Reviewers complain about phones 'only' having a 1080p screen because even low-end and mid-range devices have gotten to be so good that the only way to ding them is by pointing out how they're not 'the greatest'.

Which is not unlike most camera reviews, really...
