The jaggies look just like a poor GPS module in difficult conditions (trees, echoes due to having rock on the opposite side of the satellite, slow motion etc.).

Even the most sophisticated GPS module will draw a "star" when holding still, let alone a smartphone-quality like the ones mounted on cameras (and no, GLONASS support won't make that "highly accurate"... the old Galaxy SIII - and many cellphones of that generation - had it too, and it still was a mess).

Question: is it possible to download a *.gpx file without passing through the app, just straight from the microSD card, or is it everything stored in a proprietary file format?

Marty4650: Wasn't the Pentax K-01 "designer inspired" too?

@Will So useful it's my only camera...

PanchoVilla: A cheap Helios 58mm f/2 will get you the same look for $40 USD + purchase of an adapter. Another Kickstarter ripoff!

Right.
Or buy a Pentax, find a Helios 44K and forgo the adapter ;-)

LensBeginner: I believe that a 3D-printed plastic item is intrinsically more fragile than a cast one.

Re the integrity I was refering to the fact that in image No.1 the thing surely looks bent under the weight of the camera, as many here noticed, just in case you missed it.

I wouldn't let anything of that sort bear the weight of an even remotely valuable film rangefinder, let alone a heavy modern camera...

@electrophoto yeah I know, type of resin, heat treatment etc.
However if I had to bet after seeing the pics I'd say that in this case I'm correct ;-)

Moreover that's the wrong process for this kind of thing, they are so simple that molding is the way to go, unless they expect to sell a veeery small number, that is...

On article Pentax K-70 real-world sample gallery (65 comments in total)
In reply to:

ahw82: I love the picture of the corgi. Clearly, the least artistic composition of all the photos in the gallery--you can tell the photographer was wandering Pike Place Market and took the shot on autopilot. "Look, a corgi!" And it was still good enough to include in the gallery. Proving that any photo with a corgi in it is a great photo.

If it has to do with the 15 LTD, it's not "autopilot", it's called "mind control" :-P

On article Throwback Thursday: when studio lenses retire (203 comments in total)
In reply to:

LensBeginner: A 1995 lens being called old... what are lenses from the '70s then, dinosaurs? -_-
I can't see a SMC Pentax M 50/1.7 (because I know it, but any fifty for that matter) struggle even with a modern digital sensor, and I mean from f/2 upwards, not necessarily at peak sharpness aperture.

Many people seek sharpness wide open, which is IMHO the polar opposite of what a portrait lens should do...

You actually want some softness wide open, because that'll be good for portraits, and absolutely no corner sharpness, in order to focus the viewer's attention on the only things that matter (the face,som or facial feature, which are almost always in or near the center.

And an f/1.4 lens is almost always supposed to be softer than a f/1.7-1.8-2.0 lens.

OTOH, you'd like a lens to become progressively sharper when stopping down, mainly for other uses. I can get pixel-perfect detail on a 16MP APS-C body (and I bet I could all the same on 24MP one), maybe I'd expect some more corner fuzziness on FF (at f/2, half stop from w.o.)

That's valid for all 50s, not only Pentax's or Nikon's, of course.

In reply to:

dennis tennis: I have 4 claymore mines attached to me at all times. All of my cameras and lenses have a small gps tracker attached. If they are more than 6 feet away from me. I'll explode. I may die but the thieves will go to hell with me. I've made reservation: a nice hammock at the base of a volcano., all the acid I can drink (free refills caught on huge down there)

I suggest that you reverse the arrangement... put the mines on the gear and the safety pins on yourself... :p

In reply to:

LensBeginner: Here in Italy 1080p broadcast compression is awful... and it still uses MPEG2 compression... I think that with a higher bitrate or better algorithms one could improve things much more than increasing the resolution to 2K, 4K, 8K or some other bogus value.

Main issue is, there's a huge confusion between frequencies lost by TV broadcasting, a switchoff in favor of DVB-T2 that hasn't been scheduled with certainty yet and uncertainty WRT to the adoption of the h265 codec.

Bottom line: there are other priorities, at least here.

My bad... RAI HD is actually 1080 interlaced... LoL...

GodSpeaks: At 6.6 inches, this isn't a smartphone, it's a tablet.

It's not so awkward to have a 5.5" phone, especially with a grippy cover and a one-handed mode feature.

A phablet, if you wanna play semantics...
I don't think something under 7" qualifies as a tablet...
Hell, if it were for me a proper tablet would only be 9-10"...

In reply to:

Dr_Jon: If you need their servers to crunch the data then if they go bust you have a very expensive paperweight. I'd want the option of processing images locally, even if very slowly, before paying that much. I already have some internet-enabled paperweights that are no longer supported by the people that made them.

@jjd yeah I agree 100%, you need at least a fallback/failsafe.

...but then they couldn't automagically build an archive with all the pictures ever processed all over the world, could they?
I'd be curious to know exactly what the license terms are with regard to use license rights for the pictures...

tsk1979: No 3.5mm jack? Do not want. I think only the consumers can put an end to this stupidity by refusing to buy these crippled things, and buy a proper phone instead? What next? No Dialer, buy our 1.99$ dialer package.

Thinner than this?
Protruding camera is a recipe for scratches, camera must be indented (flush is ok, just put a plastic/silicon/whatever cover on).

N95's closed camera was, well, too good for modern times I guess...

In reply to:

Joel Benford: What is the focal length?

Well... the S3 was quite a bit wider than that IIRC... then there was a trend towards normal for a while... maybe there has been an inversion recently...

However, as I always say, the ideal FL is a compromise between moderate WA and a normal... 30-35-ish should do quite well, considering that there always is panorama mode to go wider, but you'd need a whole lotta more pixels and detail to crop a portrait in order to shoot from a reasonable distance (and avoid getting an alien face in the process...)

Panorama mode has its disadvantages of course, but the benchmark here is still "cell-phone quality", and all tricks like built-in HDR and "night mode" are allowed...

BeaverTerror: There have been a lot of articles recently on Chinese gear. I guess the days of China not being a place of innovation are over.

It's been a while now... the Mi5 from Xiaomi is just one example.

I have 8, so that would have been more difficult for me... and my PC isn't from the stone age...
What was the processing time?

Now think about target audience and average Joe's PCs

In reply to:

Gesture: Pentax K3-II versus Pentax K-1.

actually we are more than two... however you're right... discerning people are few and far between...

However, if DPReview is planning to develop that into a series, that's the obvious comparison as far as Pentax is concerned
