dbm305: First fast aperture 85 with stabilisation? Zeiss Batis Sonnar 85mm 1.8 T*!!!!!

Any fast aperture 85 has stabilization when used with bodies from Sony/Pentax/Olympus (and recently Panasonic), so not really an exciting advancement for those who own these cameras.

I can see why Canon and Nikon users would be thrilled though :-)

Prognathous: It's interesting that the only Pentax camera mentioned in this review is the 645Z. I think you may have missed a somewhat more relevant model...

Not feeding you any more.

Because an important part of reviewing a product is discussing alternatives (competing products). Is this a new concept you've never encountered in product reviews before?

mike earussi: This review was obviously written before the K1's DR test was done, because the K1 beats the Nikon in Pixel Shift mode by several stops.

It's not a Foveon sensor, it just achieves the same result by using 4 exposures, each with a slightly shifted sensor. Read this for more:

The review was published today, so they could have added a short mention of the K-1. It's only expected, given it offers the same resolution and sensor size for 2/3 of the price.

I don't have the K-1, but I think this would be a good starting point:

According to this report, only 1 of 16 shots with motion correction enabled had motion blur, while 9 of 10 shots with this option disabled suffered from this issue.

SmilerGrogan, and even if there is wind, the K-1 motion correction fixes it in most cases (according to user tests).

Pixel Shift has two advantages compared to what you can do with the D810 and post processing:

1. It is much sharper
2. It works in camera, including motion correction (most of the time)

You only have to deal with the files manually if there was movement in the scene and the camera couldn't correct it automatically. In other words, normally you don't.

Rishi, the K-1 supports motion correction for the Pixel Shift mode, and also keeps the 4 RAW files. This means that even if in-camera motion correction is not successful (and reports are that it is successful 90% of the time), you can always open the 4 files in different layers in your image editor and "paint away" any movement by only leaving one layer visible in problematic areas.

The end result is that you'd still have the superb DR and sharpness of this mode, without any visible motion related issues. This is pretty much unparalleled by any other FF camera - with or without post processing.

But why would you need great dynamic range when shooting landscape, right? ;-)

Prognathous: I bought version 1 and tried version 2. Both are fast but the resulting quality is way behind DxO Optics Pro and even the free RawTherapee - my two favorites raw conversion tools. I think I'll stick to Corel only for PaintShop Pro (which I love).

That's not my experience. I've been using DxO since v7, and it's always been clearly ahead of ASP. The big changes that came later were PRIME NR and then PRIME NR with more reasonable speed, but both are irrelevant to conversion quality at low ISO.

Eric, this makes sense, but it's different from what maximme suggested. You advise to keep the center of gravity lower, while he suggest to have it at the top.

Can you explain in words the difference? It'll be a while until I cross a stream on a log-bridge...

If the waist belt takes the load why does it matter if the heavy stuff is lower or higher in the bag?

Have you ever encountered a macro lens that *doesn't* deliver acceptable results in IQ dept?

Very nice! This should be a default feature in macro lenses.

On article Keeping the faith: Pentax K-1 video overview (96 comments in total)
In reply to:

gigabloke: In all the video reviews I have seen so far, the LCD is shown to have very limited range of movement; none, including dpr indicates that it can tilt to full horizontal for waist-level shooting. Will it not do that?

And how far to the side does it swivel? Not very far according to this video report.

It does flip up and down, but for some reason it's normally shown in the spider position, with all 4 legs extended. This position is actually not very useful and is mostly a by-product of the real reason for this design - the unique support for *vertical* waist level position (where only 2 legs are extended).

The K-1 LCD screen has a brilliant design, but the fact that people tend to pull out all 4 legs and swivel it a bit from side to side show that most people don't understand the point behind the design. Pentax should explain this better.
