Xeexon: I hate to be boring- I’ve moved on from Pentax/Ricoh system long ago (though that was my first love and how I introduced myself to DSLR photography)- but it is so unfortunate that with over sampling based on sensor shift tech, like many other technologies they’ve pioneered, Pentax was so far ahead of its time that it seemed like a gimmick when it first came out. Now that everyone has adopted this tech and rebadged it as revolutionary, Pentax is not even a footnote in history.

I’m not asking for anything to be amended in the article or crying out for justice, but I am just amazed at the crap luck Pentax has had. Was it the lag in autofocus and video that did them in, or was it just clunky implementation of said revolutionary features (or even bad marketing/assessment of customer needs)?

Would love to hear opinions, but please remember to be gentle in your criticism- I am still a Pentaxian (read: Pentax fanboy) at heart.

IIRC Olympus introduced a pixel shift that increased resolution in the file, while Pentax developed - shortly thereafter - a pixel shift that, by moving the sensor exactly in 1-pixel increments, allowed to have real color information for each pixel.

I don't know if and/or how much Olympus relied on interpolation, nor if and/or how much Pentax's claims were marketing or not, I can only say that Pentax's way makes much more sense, because in the second case you don't need to resize the output jpeg, and end up with something roughly the same filesize as a normal jpeg.

Sony came much later, and with an implementation that takes much more time than Pentax's, so I can surmise it's a little less refined

LensBeginner: These "tests" are meaningless IMHO...
Pentax cameras and lenses are advertised as "weather resistant", but I've heard lots of reports of the WR failing in light rain conditions.

Bottom line, sample variation is much too great, to the point that even though the manufacturers like to advertise weather resistance, they usually don't cover damage to the cameras/lenses involving liquids.

That's what I'm saying.
I've seen videos of cameras submerged in a swimming pool, covered in sand and washed under a shower, and then some people have their failing after 10' light rain.

Too much variability, no certainty.

In reply to:

LensBeginner: How do you do star trails like those in a time lapse?
I mean, judging by their length those are from exposures many minutes long, yet they move by a small amount and overlap with each passing frame.

I gather it's a PP thing?

I thought this out, and figured it must be some sort of "staggered" stacking...

For instance, in a series of pictures [1, 2, 3, 4, 5, 6], the first frame is the stack 1-4, the second 2-5, the third 3-6 etc. it's the only sensible explanation.

I feel that the editors could have added some interesting bits of information like this one, instead of just pitching the thing like eBay junk (Rare! Pristine! Mint! Mint-y!)

In the Raw: If there is one thing to learn from the rate of change in this world of rapid technological advance it is this. If you nail yourself to the mast of any one camera today, tomorrow you will go down with the ship.

Best to be on your own vessel, however old, take photos of the latest Titanic marvel as it sinks and post them here. :-)

I'm using 5-6 y.o. cameras so I definitely know that...

Still, at least 50% of my system is brand-specific (the other half are adaptable MF lenses, manual flashes and accessories), and it couldn't be any other way.

That's a catchy phrase for sure, but how are you going to put that in practice?

Only buy old manual focus lenses and adapt them on a different body if the company producing the one you are using goes bankrupt?

Or do you intend to design, manufacture and test your own camera? :-/

Windeguy: Pentax?

Pentax hasn't released anything worth mentioning camera-side this year.

KP is not what I'd call a best enthusiast-ILC.

I use Pentax almost exclusively BTW.

...so Mirrorless DSL non-R?

In reply to:

Mike CH: The point is probably not really about dropping bombs on places or surveillance or some such but rather something else:

Drone users have been making too much of a nuisance of themselves and now the backlash is coming.

I thought the people at Columbine High and countless other places would have made enough of a nuisance of themselves to make someone act, even if only out of spite...

Oh, well... drones are dangerous, after all.

Akgbkd: Pixel 2... Best camera for parents

@anticipation

That is based on the assumption that everyone can sit in the front row... 5-10m can make a big difference for smartphones, since they have a fixed, wide-ish angle focal length.

In reply to:

O_O: I guess that F22 allows more background details. With a slower shutter speed, the motion blur effect is much stronger.

An F-22 would have been faster, I think... so, yeah, more blur! :P

Thanks for the interesting trip!

Scottelly: Does anyone else see that the Pentax K1 is conspicuously missing from this list? It has advantages over the Nikon D750, and costs the same, right? How did the D750 make this list, but the Pentax K1 didn't?

...if you say so...
