On article Special K? Pentax K-1 Review (2597 comments in total)
In reply to:

tassosDA: This is a good and honest review. I really hope that Pentax will work hard to improve it's AF system and make it compare with best in class, and NOT with previous generation Pentax AF!! Basically its the last point of criticism (together with video specs) of an otherwise excellent camera...
Com' on Pentax, give us top notch auto focus...

it's not clear (to me) in the reviews if they adjusted any Focus Hold or Expanded AF area paramaters in the AF tests. Did I miss that or did they just shoot at default AFc settings, whatever they may be?

And all my Pentax bodies were set to zoom to 4.7x (I think) as the first playback zoom step. I'd be amazed if Ricoh decided that was not of value in the K-1..

On article YoCam is world's smallest waterproof 'life' camera (28 comments in total)

My YoCam arrived today. It will do just fine for what I need it to do, since I have other cameras to do other work. It updated FW and linked to my phone with little effort. Should be fun for snorkeling and other typically camera-averse fun.

On article Pentax K-1 Pixel Shift: An update (96 comments in total)
In reply to:

brycesteiner: I get the point of Pixel Shift on Olympus: It gives 4x the resolution of the standard sensor, but I don't get the reason in this camera. At 36MP it's fantastic already and I don't see that it will have 4x the resolution like Olympus. So what is the point of Pixel Shift on this camera?

Here is the website:
"The K-1 uses the latest super-resolution technology, which captures four images of the same scene by shifting the image sensor by a single pixel for each image, and then synthesizes them into a single composite image. Since the K-1’s SR unit has a flexible design that tilts the image sensor unit in all directions, it provides a host of handy shooting functions, including auto level compensation, image-composition fine-adjustment, and ASTRO TRACER, which simplifies advanced astronomical photography using a built-in GPS module."

The camera looks amazing. I'm just confused on what Pixel Shift does because from the comments it doesn't sound like the picture is 4x the size.

It allows red green and blue color information to hit every pixel, in essence removing the Bayer color array from the equation. It could be done with three shots in theory since four shots gets two green. If you read about the Foveon sensor that Sigma uses it always gets great color-fidelity marks. It provides data above and beyond mere pixel-count, which is why Sigma states their cameras as providing 2-3x the pixels to try and level the 'playing field'. However - with four shifted images the raw process gets complicated.

FastGlassLover: I'd switch if they had lenses to cover the lenses I use. Yes I checked, no they don't. Killer camera!

While it won't replace thin-DoF images, this sensor performance allows most of us to manage with slower glass and still get excellent results. Hopefully R/Pentax will add lenses for FastGlassLovers such as yourself. :-)

On article 2016 Roundup: Compact Enthusiast Zoom Cameras (286 comments in total)

It's always weird when reviewer-defined series overlap. It's hard to consider one of these without including a small ILC that can do very similar things yet swap in a different lens when the need arises. Especially when some of these are $700 and more.

In reply to:

mikey fried: good video - short and sweet - more like this please!

And yes I'm sold on the camera, will probably replace my G7 as prefer the form factor and stabilised 4K is a winner. Just a shame about the type of viewfinder.

You also gain 'shutter shock' immunity, in theory. That would be a very good thing!

SungiBr: @Carey Rose

"One downside of these (really) old primes - no metering. None. Not even an aperture measurement on the Raw files"

Good pictures and nice article, but you might want to know.

As usual on all Pentax cameras, you can meter with non-A lenses.

In Manual Mode, select the desired aperture with the ring and push the Green Button. The camera will stop down and meter the apropriate shutter speed.

Works elegantly fast and accurate. But you have the annoyance of not knowing the apertures used.

Note that having a lens with an 'A' setting allows for automation but you do need to set the ring to A or it will be a fully manual-metering lens. That's obvious to most folks but it should be clearly stated, as only when set to A on the ring (where it locks into place) will the data flow :-)

On article The long, difficult road to Pentax full-frame (617 comments in total)
In reply to:

Richard Murdey: "Pentax planned to release a FF dSLR in 2001, they even had it on display. Then they killed it. Then they released medium format cameras. Then they released the K-1".

It would have been nice if you'd managed to flesh that out a little with something we didn't know. Why was the K-1 delayed? How long was the K-1 in development. What changes did it go through? What were the major challenges?

Nikon gave an interesting behind the scenes look at the Df development back when it came out (to dcwatch iirc), so there is a precedent...

Pentax has released new K-1 specific web pages that will be covering much of the history; perhaps Barney knew that..

On article The long, difficult road to Pentax full-frame (617 comments in total)

Nice write-up, and from the heart as you say at the end. I've planned to be an APSc-for-lifer, having tried many smaller sensors and just not been smitten despite the advantages. And 36×24 really held no interest, nice images but too much more bulk.

And yet..
5-stop SR for any lens I chose to pop on (even my JCPenney 80-200/3.5)? Enhancements like PhaseShift update, screen dimming and tiny LEDs for dark imaging? Real tethering, and my choice to crop images with crop-sensor lenses? The best of Pentax core features plus some surprises that really strike me.

Many of the new features are not built with me in mind, and video is still just where Pentax has always said it would be: available but not a headline. But wow, something for everyone exists with the K-1. Ricoh did well.

Plenty of great video options now to supplement my Pentax K∙50 with its relative lack of advanced video features. Despite its name I feel the YoCam is more interesting for my purposes with its size & submersible + time-lapse options, but I'll keep watching for a while..

On article Sigma 20mm F1.4 'Art' lens real-world sample gallery (137 comments in total)

Guess I'm too old to get the allure of really fast WA lenses. Bokeh was never among my reasons to shoot wide, and size matters to me so Pentax 15mm f/4 or the 10-17 fisheye zoom will do fine. I'd like my entire set of lenses to weigh 950g!

On article Opinion: Pour one out for Samsung cameras (324 comments in total)

Maybe it's time for Pentax to reopen its cooperation with Samsung? Help to relieve them of some spare gear they no longer want? :-)
Just dreaming.

Despite the Samsung silence I repurchased the NX300, a really capable camera with some great tiny lenses. The S series zooms may be excellent but are way too heavy for the thin-grip models; the 16-50PZ on those bodies can do great things.

In reply to:

cgarrard: Another thing I'm noticing is the new camera seems to be a big bigger and bulkier than normal Pentax cameras- to me that is an asset for full frame. Less vibration to cause micro blur- especially important on these new high res sensors without AA filters (and likely this one will not have one either). Also, the bulk helps handling with larger lenses. I never understood the small FF camera with large lenses... very odd to handle for me.

I do like the smaller FF cameras mind you, but just with the smaller prime FF lenses. A camera like this can handle the big glass Ricoh has (and will continue to) announced very well it seems. Handling is important to working pro's and they are used to carrying around extra weight - that is just part of the job most of the time.

Count me among the trivial DSLR users then; I stop at 500 grams for my lenses. I've owned heavier and find I always grab something else instead. No doubt all my images are pitiful.

In reply to:

Class A: This camera has the potential to become an instant classic.

I'm very excited about the new controls and expect this camera to provide excellent handling.

'tis a shame that Pentax' pixel shift and AA simulation were not enough for an innovation nod. The NX1 has some excellent and unique features though.
